i also have had experiences where i have a buyer that would replace the parts that i sold him with exact same parts but are defective. so always make sure to have records of serial numbers of the stuff you have to make sure he didn't swap stuff out for defective ones.

Hey dude, when I build machines for people I take pictures and keep a file on my NAS of the build and finished product. To many times people will take stuff apart and screw it up and then try to come back and say I made a mistake. Then I pull their file and show them the pics and that pretty much settles the issue then I charge them to fix their screw ups.
I had a faulty CPU in my 2016 Touch bar Macbook (i7 6820HQ) and it was incredibly hard to get Apple to accept that there was a problem with the machine, their own internal stress tests couldn't replicate the problem, so even if say rendering in premiere would cause a crash report from the kernel saying the CPU was bad, or I'd have kernel panics they wouldn't accept a warranty claim because it'd pass their diagnostic.
Nope... We shouldn´t have to. When paying up to a 1000 dollars for a product, it should be expected to already come in perfect condition and with good paste or liquid metal. It should actually be soldered to the cpu itself like amd has done with their cpu´s.
@@datreja9573 We should get a decent product even if we pay a fucking 100$, especially every K and X cpu, why are we paying the premium for them then? 1st time I bought from intel and was already disappointed with their garbage 7700k toothpaste. Had to spend additional 9$ for some liquid metal and 2$ for some knife to delid it. After that I could finally have 5ghz with 75c and not 100+.
Memory, bent pin or dust in socket, blown PCI lanes, bad sata, fried chipset. It is rarely the CPU though i have had it happen but your right it's usually memory.
@Adam W I already have seen more faulty or even dead CPUs (i5 6600k, i5 6400, FX 8320) than any of these problems though. A buddy of mine bought an i5 6600k from Mindfactory (biggest German/European e-tailer for pc parts) and left it at stock (MSI Z170-A) and it died just months later, meaning it would crash @stock constantly, had the Windows boot screen watermarked in UEFI - it was weird all around - and ran fine lowest clock of @2.4 GHz in Prime95 for just three minutes until BSOD. Swapped memory, board and PSU and the problems persisted until I swapped the CPU with an RMA sample, no problems since then... I also built a PC for someone on a budget with an i5 6400 from eBay from a commercial seller with >5000 feedback (99.9% positive) as "known working, even optics checked" and it came bent. I know Skylake had some problems with bending, but never had that problem myself until then (have an i5 6400 in secondary PC @4.7 GHz with DDR4 @>3800 MHz xD), so we thought the bluescreens (somewhat counteracted by adjusting system agent voltage and similar) and program crashes would simply be caused by the (DDR3 bclk oc Z170) Gigabyte motherboard which was in for RMA already. Since we also tested and another chip (almost known good Skylake ES "QH8F" - guess who inspired me) also was unstable, this was pronounced. Turned out the motherboard was bad and was repaired just luckily a few days before warranty expiration from September 2016. After repair strangely everything worked fine only with memory in channel B, with any out of piles of memory in channel A and/or B the PC did not boot. Turns out the chip was damaged due to the bent. Since I life in Germany I thought: "No problem I have two years warranty by law with six months of "burden of proof reversal" (direct translation of the law), so I just need to tell the seller. The seller declined because I did not return the item within two weeks after purchase. Excuse me, someone does not know law here. After many fruitless mails I let the case rest until I met a lawyer that would take my case for free (only would take a cut of the fine), so I got 60€/71€ back from my purchase, after the seller received a legal letter. The chip however still works fine in single channel even @4.3 GHz (4.4 GHz was unstable @1.38V so we stopped there) with just two slots and it was almost free. :D Also know a guy whose FX 8350 was dying (random bluescreens, lacks and program crashes or complete boot failures). He against my advice did buy a new motherboard and had the same problems (PSU, HDD and RAM already known good and replaced). He eventually got fed up and sold the chip as non-working alongside the other used parts on eBay - so I borrowed him my aforementioned spare PC with overclocked i5 6400 and he (apart from his new motherboard, the CPU and RAM) still uses the same parts and only had one bluescreen since he hot-plugged a HDD and no further problems. And since he is no stupid fanboy, he is considering saving up for a Ryzen build this year because of the value and new components. He really did not want to switch to a random Intel platform just to keep his DDR3, which I second. Furthermore I have some CPUs with bent pins, but that is another story, since these CPUs are technically repairable unlike with internal damage which is irreversible. So yeah, CPUs get faulty or die more often than many may think, source: my experience: Built and mantained about ten PCs 1x memory (very cheap stuff) 2x bent pin (once did it myself, repaired all) 0x dust in socket or similar 1x blown PCI lanes 0x bad sata 0x fried chipset, maybe more but idk for sure, could be 0 to three times Meaning all known to me apart from mostly irrelevant or fixable cases of system failure mentioned in the list are less for me than dead or failing CPUs, so really not that uncommon sadly. Still way less likely than RAM, other motherboard component, HDD or PSU failures though. Only unfixable and stability affecting one was RAM in one case for me. Also never had any fan die on me ever apart from two very cheap ones which died within the first second of use (one the same fan header any of my other fans worked fine and they are similar CPU fans).
@desertrat810 That all makes sense, since I think the most failing CPUs are either old hot Intels like Pentium 3/4 or similar AMDs like Sempron, Duron or FX and newly those flashy new Intel chips. Hell I've never seen that many dead CPUs before Intel 's now infamous 14nm node and I don't think Intel's "rise" in popularity or dumb and careless customers are to blame - tech gets more fragile nowadays and who can repair CPUs that small? I think running them with bad components can kill them, but I admit I put an i5 2500k into a bent socket for testing and the socket was shorted (VCC to GND) so that it basically unsoldered a gold contact pad from the CPU which I had loose afterwards. The funny thing is I send the board to a person repairing it for 40 bucks and put the CPU back in and everything worked fine. So, I guess moral of the story: Don't do that even if it worked out for me. xD Really any of the CPUs I describe here are not very old just 7 months for the 6600k, at most since Skylake released (then 2.5 years ago) for the i5 6400 and I think 8 years for the 8320. Especially the latter ones die like flies, but who cares FX was long dead anyway I recon and any real gamer can attest that. So to anyone doubting: I have many CPUs and none of that that died/are dying were run overclocked at any point by myself, so that is ruled out as a factor. In contrary most of the other CPUs I have were tortured to the brink and many were in now dead motherboards and still work just fine.
Memory 9 out of 10 when you are installing it while power is running through the motherboard as well as handling the memory stick on the memory chips rather than the edges of the DIMM as shown in this video.
I once had a 4790k that had some weird issues with low power states (c6/c7), the system would freeze after ~5 mins in idle. Disabling these low power states fixed the problem.
I had that on a CPU (not Haswell), and it was the lower voltage causing the instability. It would run the lower speeds fine if the voltage was manually set. What you did makes perfect sense. It's been tested and the power difference is negligible between letting the clock speed and voltage drop and manually locking both. The current is drawn on load anyway, and the power difference between a small process completing at full speed vs taking longer at a lower power draw is small. It comes down to efficiency at that point. When I saw the numbers on a modern CPU with everything locked vs all of the power savings running, I stopped worrying about it.
Haswell was kind of a wonky generation. I had a 4790k that was an awful overclocker, couldn't barely get to 4.6 GHz and had it running most of the time on stock because it was so unstable, really.
@@pedrobastos8132 I'm actually still using a haswell CPU, an 4770k that I picked up rather cheap in a bundle. I overclocked it to 4.5GHz/1.32v and it runs perfect in combination with my 1060. Temps are also good using an Thermalright Macho Rev. B, the only issue is the core to core thermal difference, core0 to core3 are under load 7-10°C apart. I might delid it soon but since the temps in general are fine (70°C max at non-avx load) there isn't really a need for that.
I bought a used 4770k on ebay for a friends budget gaming PC . It had very similar problems to the ones in this video the thing is that it was already delided and it wasnt overheating. Turns out the cpu just wasnt making contact with the motherboard pins and crashed etc etc. Real pain to get the thing working though good thing the YES man didnt have that problem with a actual faulty cpu lol also LOVE the content keep up the good work mate.
The only faulty CPU I ever saw was a Cyrix PR 200+ that ran way too hot and kept crashing no matter what standard cooler I used. Went back to the shop and swapped it over for an Intel 166 mmx that I overclocked to 200Mhz from the day I got it and ran perfectly ever since. But I guess no-one remembers these anymore... like Intel's first low budget overclocking beast, the Celeron 300a... I'm getting old...
i had a dual P2-333 system back in the day, and ran into it getting unstable and found that the fans on the backs of the cpu cards had clogged all to hell. after cleaning them out (positively nasty after seven years of multiple climates, and the fact that i smoked didn't help), it became stable again, with no actual damage as far as anything that i could use to test it.
I had a Cyrix 5x86-100. Cyrix chips were notoriously hot CPU's, but I found most of their problems stemmed from software bugs and incompatibilities. I started into overclocking with the Celeron 300a on an ABIT BH6 motherboard, it was a very simple overclock of the FSB from 66MHz to 100MHz and CPU clock speed increase of 50%. The Celeron 300a was actually a better CPU for gaming more often than not vs. the much more expensive Pentium 450, because of faster L2 cache even though it had 1/4 the amount. Overclocking back then was physical dip switches and jumpers on the motherboard, not fancy BIOS settings.
Everyone keeps saying the same thing. A dead cpu is rare. But whats even rarer is a brand new 9900k dying on the first gaming session. How do i know its dead? Swapping out the Cpu to a 8700k, it boots. 9900k it just wont boot. So here i sit, listening/reading the countless amounts of “its very rare a cpu dies” being told to me. While slowly accepting the fact that im hella unlucky...
Different story, but something was wrong with the PC of my mum. It kept crashing and never turned on when we hit the power button. We sended it five times to the merchant who sold us the pc. Every time he checked it, he said it was fine but never fixed anything. My mother was one of those people who threw everything away if something didnt work and would buy a new one, so I suspected the merchant never looked inside of the pc, which everyone should do, if a customer tells you something is wrong with the pc. We returned the pc again and he became salty because he had to check the pc again. Then I told him "Then you clearly never looked inside! Seriously! You cant do small tests and say everything works well." It was clear in his tests the pc was running fine, yet he never looked inside, simply because all what he did was to check if the pc is turning on. After telling him my mind, he did check the components. It turned out the PSU had a faulty, he replaced it and apologized for the mess. I asked him what kind of a technician he was and we didnt pay the last repair bills for all this mess. To that time I was 14 years old and didnt knew much about pcs.
Theres 10% wiggle room on ATX voltage specs. And only 12v is relevant here, which further gets converted both in the motherboard VRMs and in this case on the CPU FIVR.
@@Brandon-uy1uv Lol i know, but down under we just call all types of spray wd40, its a weird thing. The aussie export, multipurpose stuff is the best thing going.
I recently picked up a Xeon E3 1270 V2 for $60 on eBay and it performs like a $100 i7 2600 if not slightly faster. I was worried that I would run into microcode compatibility issues cause HP does not list Xeons as compatible with their Q77 chipset boards, but the CPU worked without a single problem.👌
My 4790 is on the warm side too, but since it's not giving problems and as you say it's still somewhat expensive, I'm not going to risk delidding. But maybe some day.
@@webbie7503 I have the same cpu. But it gets really hot. (50 - 55 C idle) (70 - 85 when gaming) I dont know if it is the cooler or the cpu whos causing the issue. The cooler isn't great i think its a spire sigor iv, but anyways i just wondered what cpu cooler you have i need tips :D
I'm not sure why, but despite the exact same architecture and only 100mhz speed difference I've never come across a Haswell xeon that's had the same issues with temperature, even spite of the fact many where used in much higher duty cycle loads with smaller cases/coolers than there consumer breathern. Could it have something to do with crystallization of the TIM with heat cycles rather than actual drying, or perhaps that these CPU's never saw attempts at being overclocked? Or may there have been a difference in the binning/selection criteria? Either way, they are a pretty cheap/widely available part still, so if your buying used and your not getting a K skew, I'd compare prices.
You are onto something there, I noticed with some of the mining experiments I did back over a year ago, that some GPUs would be fine* to just keep on running, but take them down for a week then try booting them back up and you would have to change the thermal paste. Something to do with cycling from hot to cold?
umm I'm gonna say voltage is the answer? my E3-1246 v3 needs only 0.89v to maintain 3.5ghz and 1.01 for 3.9ghz "turbo" speed, the 4770 I got rid of needed 1.19v at 3.5ghz and 1.22 at 3.9ghz... both kinda won the silicone lottery, and tested on the same boards. the 4770 needed more volts, hence ran hotter than the Xeon at the same speed...
@@C-S-J True, however the Xeon E3-12xxv3 of the LGA1150 socket is in fact thermal paste, not solder, and are the directly comparable parts to the i7 4770 of the video referenced in the video... and yet doesn't seem to face the same age related overheating or instability as the consumer i5 and i7 chips. This is why I'm speculating about either binning differences of the core itself or effects the different use cases have on the longevity of the paste. And the conventional logic that more use and hotter running would correlate to drier paste and higher temperatures later in life doesn't seem to hold up with my experiences on the platform.
Xeon's are better binned parts for Enterprise systems that need power efficiency and stability. So of course it makes sense when a Xeon counterpart from the same architecture runs cooler and with less voltage than their desktop counterparts. But yes, Haswell was a very hot architecture in general (even hotter than Ivy Bridge) compared to Sandy Bridge, and most overclockers were better off with the 2600K due to it's best performance without the hot temperatures since it was soldered. That may be why a lot of people never upgraded from their 2600K until Coffee Lake came around. This was fixed when Skylake came out with the 6700 being quite cool when you're not bumping up the voltage, just to be undone once the 7700K came out due to the high clock speeds and obviously the poor choice from Intel to use TIM on enthusiast parts. Ivy Bridge and Haswell overclocking ARE NOT the same procedure when compared to Sandy Bridge. The 22nm Tri-Gate transistors are much more sensitive to voltage than the 32nm transistors we saw with Sandy Bridge. This can prove to be a pain when overclocking since you may need to bump the voltage to reach higher clockspeeds, but that may cause the heat to ramp up with it. And we also know that voltage does cause a linear increase in heat either. As for thermal cycling, that's a lot worse on a CPU and GPU than if you ran it constantly at the same temperature. Large temperature spikes can prove detrimental to hardware. It's why mining GPUs are usually actually in better condition than a GPU used for gaming because a GPU used for gaming will be thermal cycled A LOT between hot and cold temps. And there's miners that actually ramp the fans up and undervolt their GPUs also to keep low temps. Thermal cycling can cause PCBs to warp over time and solder to crack. In fact, the Xbox 360 had this issue where it would get very hot under load, cool off when not in use, and over time this caused the solder that held the GPU in the socket to crack and cause the GPU to stop working, and thus the red ring of death would occur.
Well, prime95 is nice, but usually takes a lot of time before you can encouter an error. What is somewhat better to test CPU/RAM is Intel burn test which uses linpack. Usually it is enough to run 10 loops with maximum ram to find if the computer is stable or not :)
Filip Doležal just throw in call of duty 4 blackout run zombies it’s best stress test yet trust me got my i7 9700k at 5.2 ghz at 1.325 volts its amazing !!! Stays in 50-65 while gaming on just 120mm aio in push pull and fan over vrms!!!!
you can only truly test stability with a mix of stuff. start with the IPDT, then stuff like aida64, then intel burn test, then prime with FMA3, then real-world crunchers like seti@home. i have found that everything would be fine, until seti@home (lunatics avx client) would show it to be unstable. if you are looking for an unconditionally stable oc, you need to have a large set of synthetics and some real world stuff.
AVX generates more heat, and you may need to set up an AVX Offset in the bios, to downclock the CPU by -1 or -2 on the multiplier when AVX instructions get hammered like that.
@@mrlithium69 I think AVX offset was introduced later. I have the Gigabyte Z97 flagship board for my 4790K, the GA-Z97X-Gaming G1-WIFI-BK, and it doesn't offer that. I'm pretty sure that ASSRock didn't either. Not sure about Asus, as my first modern Asus board is a Strix Z370-I (prior to that, my previous Asus was a 286 board).

Over 2 years now I've gone through 3 sets of RAM, a 1070 and 2070 GPU, an SSD and NVME.2 storage for the OS, and reinstalled windows several times. Yet my system still crashes semi-regularly. Sometimes daily. Sometimes weekly. Raaaaaarely I can get 3 weeks without a crash. I'm confident I have either a bad CPU. Why? Because while installing my AIO cooler I was trying to squeeze it on suuuuuper tight with a LOT of pressure, before I realized I could loosen the screws to get the AIO mount on, with ease. And you know how AMD's PGA sockets are.
I’ve seen other symptoms like stop codes consisting of CLOCK_ WATCHDOG_TIMEOUT, WHEA_UNCORRECTABLE_ERROR, DCP_WATCHDOG_VIOLATION, and/or MACHINE_CHECK_EXCEPTION.
i usually just use IPDT from intel and when it says it's good, i just trust them. but if something else goes wrong, it usually is very accurate what's a bad processor or not. takes five minutes.
The only 'faulty cpu' encounter I've had was a i7 860, which had a faulty memory controller so half the motherboard ram slots wouldn't work (I tried a different cpu and the all of the slots did work, so I was sure it was the i7 860)
Wow that's bad. I think I have a faulty X399 board that acts the same. The only defect/weak CPU memory controllers I've seen are Ryzen (My Ryzen 1700 can only do 2666 reliably, though that's technically not defective since anything over 2133 is "overclocking", its still REALLY weak!). My Threadripper 1950x does great with quad channel 3600 (plus some overclocking on top of that!), BUT.... If its cold, around freezing, (which sometimes it is in my room), it can't run full speeds. At roughly 0c, the Threadripper starts dropping memory connection, and 32GB turns into 24, and then 16... And then you need to drop it down to 2133 just to boot, then run some loads on it to heat it up so the rest of the memory detects. I'm 99% sure the motherboard is faulty based on how it just drops sticks of RAM completely when its cold. The lowering of stable memory speeds however is normal, and a known fact for Ryzen based processors acting up when cold (so don't run dry ice or phase cooling on them, but liquid nitrogen gets cold enough it starts working again for whatever reason). This memory issue was a huge pain in the butt when I was testing my LN2 cooler with regular ice (so the coldest it could possibly get was above 0c since there was melted water at the bottom of the cooler, still had these issues, so it can happen in the morning on any cooler). I'm very certain that its a bad board though, the CPU seems to bench fine at 4.15 Ghz on a 120mm AIO and 3600+ Mhz quad channel RAM most of the time, it only seems to crash when its doing nothing in the desktop (or 4x Handbrake encodes at once, but that could be a software conflict, though I normally run 2x at once...)
"Do NOT use Prime95 versions later than 26.6 on 2nd through 7th Generation i3, i5 or i7 CPU's, which all have AVX (Advanced Vector Extension) Instruction Sets. Recent versions of Prime95 such as 28.1 and 28.9 run AVX code on the CPU's Floating Point Unit (FPU) which causes unrealistic temperatures up to 20°C higher.

I have a Core I7 10700 cpu and after a year of owning it with moderate use and adequate cooling with a. high end motherboard and PSU I did downsized my pc from an tax to a mini ITX build still with the 80 plus for PSU and a nice motherboard I was stress testing it the temps only went up to 50 Degrees C. 3 days later I turn it on and I'm greeted with a no screen and a RED LED CPU on the motherboard, I swiped everything and the problem is still here so for sure I have a dead CPU. I hope intel will do there job to send me a replacement.
I have an i7-920. Sometimes in summer it started to have weird crashes. Turned out it was overheating to 99°C. I completely de-dusted everything inside the computer and it has been running smoothly since that. It is easy to overlook heating problem possibilities until you face one first time.
A computer should be cleaned and thermal paste changed about every third year I would say. Depends of course on the environment. There is software like HWinfo64 that can help you keep track of your computer and thermals. Thermal Paste always gets hard with time. That and dust would probably be one of the two major reasons why laptops tend to die rather soon (3-6 years).

Been in the computer industry for 30+ years and the only Intel CPU I had fail was a Pentium P5 90 MHz CPU in 1994. Had more problems with AMD CPUs, but not in along time.

My computer is just going slow, takes a long time to boot up, and sometimes files don’t completely open I just get a blue spinning circle. I’m just hoping it’s the HDD and not the CPU. Assuming 7hats the case, I ordered a solid-state HDD and hoping the7’ll fix things. Your video tells me though, I need to take the heat spreader off of my CPU and check the paste and if it’s dry I’m going to have to go back to Amazon to order some heat paste.
My i54590 was going over 100C load on stock cooler but after upgrading to hyper 212 turbo it stays at 60-70C at load weird for a locked cpu might be the TIM like in your video
THANKS! you saved me from throwing away my 7700.... I bought this second(?) hand cpu for an old mb and it worked fine for a couple of days, even benchmarks all below 85C until it started freezing dead before boot... it just froze either before post, during post, or after a few seconds at the bios screen when I managed to hit F2 in time... I swapped it for an 7100 i have laying around to modify the config to lower the ratio, fix the cpu core voltage at 1.125, and disable turbo-boost... then back to the 7700 and it FKIN WORKED :D... It's running hotter than usual but at least it's not an expensive paper weight now :D
I had a i7 4770 that I delidded, I didn't seal the IHS to the CPU little board. I used Arctic MX4 both between CPU die and IHS and between IHS and cooler.

Before delidding I had 70 Celsius in idle.
in my lifetime, i experienced an old cyrix m2 processor fail completely. otherwise, im with this intel dual core 2nd gen living it through all the ages, replaced like 4 or 5 motherboards over the years. motherboards are generally the first thing to fail. maybe the power supply too.

My Ryzen 2700X was a faulty CPU. The impossible happened. Wasn't hard to identify it/ It was just unstable. System was freezing whatever the memory settings, whatever the voltage. I managed to keep it stable at 4.2 GHz and 1.34v (yes the chip didn't crash at around 1.3v in prime95: "golden chip") with 16GB of cl14 3200 memory. XFR2 and PBO2 didn't work at all. System hang up while booting. After a few weeks nothing worked. Even 3.7 GHz with 1.4v and cl18 2133. I tried different hardware. Wasn't the powersupply either. And my Crosshair VII went through RMA too, they sent it back, so by conclusion it wasn't the motherboard either. Well RMA just gave me a new Ryzen 2700X. Been working fine in the last 6 months. And probably will just do fine in the next 5 to 10 years.
I been around computers since MS-DOS days never once experienced a faulty CPU where it kind of works and don't work. I stopped using Intel processors after Pentium II Slot 1 CPU and decided to use AMD processors. My reason for doing so is AMD processors tended to be cheaper then Intel Processors. But week ago I was able to snag a used i7 8700 and motherboard for $50 dollars. Which replaced my AMD FX8320 which I been using for the last decade. First time using a Intel system since Pentium II Slot 1 days. lol
I've got a persistent crash problem with no error message (black screen) and then it reboots itself. I currently have a computer from this era (i7 4790k) however I don't believe my problem lies with my cpu at all, I had an i5 4460 prior to this, I also have a gtx 970 which I believe is the fault, the black screens only occur in games, more often than not in older games, like MW2 it'll crash 95% of the time over 30-60 min usage, newer titles may take a little longer to crash, temperatures are fine (core wise) on both CPU and GPU, I've tried overvolting my GPU at stock clocks, to no avail however, it still black screens. CPU I running at 4.6ghz @1.22v stable. Any help or advice would be appreciated I've had this problem since I bought it in 2015 Specs; MSI Z87M GAMING, i7 4790k, GTX 970, 16gb HyperX Savage RAM 2400mhz, 620w Seasonic PSU.
I had the same problems with an Engineering sample cpu, it is running mostly fine now without changing much of the settings. I did change out the motherboard battery and that increased the booting stability a bit.
I’m having issue with pc build, when installing windows I get error message 0xc0000001 Stop_Thread_Handle_Exception_ Error_ message. At first I thought it could be the m.2 SSD so I flashed the BIOS and still the same problem occurred. The next step was to try the each memory stick and each one still gave me the same message. I even tried installing the OS on a different drive but that did not solve my issues. I’m coming to the conclusion that it may be a bad motherboard or bad CPU but not sure. Any assistance or advise on this matter would be appreciated.
I bought a Cpu and mobo 8 months ago. It didn't started quite well, random shut down, freeze etc. But recently when i start computer it just opens but all the apps disappeared, basically it's gone. When opened the intel i-3 10gen processor just showing burn mark really unfortunate, intel won't relplace it because of burn mark...
The motherboard overestimates the voltage on the processor. 1.21 volts, is enough for overclocking 4.5 GHz, if you have a good cooling, ofcourse )). And this processor is extremely successful, its nominal voltage can be seen after resetting to the initial settings at the first start. In your case, this is 1.028 volts or so. If you just fixed this voltage, the system would work stably and without scalping. My 4770K CPU is working on 1.046 volts by defolt clock and 1.21 at overclocking to 4500 GHz. It s easy )
i mean it's a testament to Intel that we look everywhere else first before blaming the CPU. back in the 90s, Asus was like that for their MBs and Kingston ram had a lifetime warranty for a reason.
The CPU was not faulty technically, had a dried thermal paste, a faulty CPU can't be fixed, since is the circuitry itself, you can say it had a faulty functioning because of the thermal paste, yeah you can say faulty but need to make that clarification
I have a i7 4770k and have no idea why the pc keeps just shutting off. Sometimes the pc is just idleing and it shuts off. Just watch low stress content and boom off. Thank you for letting me know about it's thermal grease. It's come down to the motherboard and CPU. Retesting the ram one more time before I delid the cpu. Other option would be to buy a motherboard first and see if that works fine. That would be sad though had an amazing formula VI motherboard. Going to just buy new set of ram. Worst case scenario I end up with extra ram for my system. Do let me know what would you recommend I do?. I have changed the power supply, tested both the rams, added a new cpu cooler with new grease, tested it on unraid still turns off, remove all hdds and tested it still turns off, removed most usb plugs, changed grease on gfx card which made it 12c cooler understress. Ram test just turned off was at 92%. Temps are generally really good on the cpu. Below 37 max 50 to 60. Will try Prime95 tomorrow.
My recent issue with 4th gen i7 4770 is it never gets heated up 😂😂😂28 to 30 c only. My system shuts down after 30 min Or an hour. Never starts after that. May start after a few hours. After watching your video, and changing CPU ratios it worked. On stress test the temperature was 70-c.b At idling 35-c. The system worked for 5 hours now, today. Thanks buddy
I've got an i7-4770K that hard freezes under load, I think both of my Z87/Z97 motherboards show the Vinput as 3.9V (?!), but my B85 motherboard has a 1.8-1.9V Vinput (which I believe is more correct). I also have a totally dead i5-4440.
jeez that paste is worse than my older I7 2600K which is at 4.9ghz on air, but I bet the only way its actually working is because of the huge cooler and I really tight it too hard (harder than I would ever do to anyones PC :) ). But I'm guessing its squeezing him a lot lowering the thick shitty black glue so the thermal compound will be squeezed and get thinner. When I cleaned the cooler and put Artic MX4 (had MX3 before), all the CPU pads even have holes from the motherboard pins, but not that I care its still kickin ass and if I ever delid it I would put liquid metal and aim for 5ghz if it dies it dies. I use OFFSET+ voltage for the OC +0.155 its close to red, but I tried going a few steps higher, but still no chance of 5ghz here, CPU not delidded :(. ps: Anyway it was way easier to bring the CPU to 4.9ghz than actually getting the ram to 2133 mhz working that took me quite a bit as it was always not accepting because sadly I have a mixed ram, the first ones were actually way better than the ones I bought a few years later which are high voltage sadly and the timmings are even higher than the ones I bought in 2011...
I have a 4770 and I'm now wondering if my CPU has gone bad. Temps are fine, usually 30's when idle, 50-60c when gaming, but 2 times in the last 3 months my PC has done a slow freeze and lock up. When this happened, I was playing a game on one screen with Chrome open on the other with task manager and Afterburner background. One time the game froze 1st, then Chrome. Other time it was reversed. After those 2 froze, the task bar would slowly become unresponsive. Afterburner freezes. Any other programs open would also slowly freeze. Task manager is always the last to freeze, but clicking End Task on frozen programs does nothing. Then it's frozen too. After about 5min or so, the mouse and keyboard stop responding. Only 3 things I haven't swapped out is CPU, main SSD and MB.
My 2 year old workstation, which is still under warranty, has had the PSU replaced, and then the Motherboard. It's still failing for the original fail, four beeps (power error). Nothing on the screen. Problem not the SSD, any other drive or the GPU pulling it down. Same beeps with only one stick of Memory installed, and CMOS reset button made no difference. It must be the XEON E5 CPU.... what else could it be...??? This offering from Intel is a server-grade processor. How often do these things fail?
I have an i5 2500k and an ASRock z77 extreme 4 (p2.90) but no I was unable to change my cpu speed or overclock it. The clock multiplier just came back to 37x . Is this a motherboard problem or cpu problem? Please help.
can you load test a cpu to see going out….lmine is a socket 1155 intel i5 idle temp 45 when gaming 65..when gaming it shutsdown…using deepcool pro 400 heatsink deepcool 500w power supply 8 gb ddr3 12800 ram……anyway to test ram without just replacing…expensive here
The i7 4770 is a terrible CPU. The bad heat transport between die and heatspreader, the weak!! single and multicore performance. My Xeon e-1240 v3 died by faulty memorycontroller!? But this was my only CPU with malfunktion of about 80? 76 of them i bought on ebay, the e3 Xeon i bought brand new.
I just built a PC. It turns on and I can get to BIOS. When I try to install Windows I get a black screen with dots that spin for a second and then freeze. There was only one time that I got an actual blue screen and it froze there. The error was a "Machine Check Exception". After that I didn't get the error again, but it's still the same issue. I began testing it by taking out components, but when I took out the GPU and tried to use the i5 9600K's integrated graphics, I couldn't get a display. Is it likely that my CPU is the issue? Or maybe the motherboard?
this is what happen to my Ryzen 5 5600x 6 core 12 threads . i did all the thing possible to fix but still crashing on blue screen of death . now i downcore my processor to 2~0 . now im using 2 core 4 threads . darn faulty processor . . .and now its working . . .
I had a customer bring me a Dell optiplex 9020 they bought from the off lease section. The computer would not boot and the warranty had been 90 days and they were at 100 days. So they just told me to get them a used 9020 board and I5 to replace their I7 4790. At that time , nobody had listed an issue with the power switch. I still have not read the issue and now I know this issue. I still have the board and chip I pulled but I did discover that the power supply was blown. Since I did that as a favor to them, I no longer had any extra parts around for checking stuff. My guess was the power supply blew hard and took the board and chip. There was an issue with the 8 pin power supply they used having a very high failure rate. Anyone else disagree with the assessment ? The power supply did not have any power and when their used same Dell 8 pin power supply came in, I plugged in the I7-4790 board and did not get any fans or lights or beeps. I was unable to check the CPU without old parts, The customer was using the computer daily so, I did not pull the I5 and take a chance on damaging their board in any way. So chance the I7-4790 is alive ????? I vote it is dead because of the definitely dead PSU and Board. PSU had the reputation of popping as it died with a high failure rate.
So... I know this is an old video and the chances of anyone seeing this is quite low I bent the CPU and I chucked it back into the computer and it boots. However, it failed the prime95 blend and Smallfft test. Froze up within an hour. Currently I am trying Smallest FFT. Does it mean my CPU is failing and I should get a new one?
Yes, you must test for faulty CPU cores and other issues. No, you don't get to ignore that just because it is rare. This is part of why shops charge a bench fee and many often charge more to work on Intel-related hardware issues - I only need a few AMD chips to test dozens of boards but I need dozens of Intel chips to do the same. More overhead = higher fee. Thanks, AMD! ;) Also no, 78 is not that warm for a room. Is that warm where you live? It's normal in the USA. -Most PC technicians who actually do this shit for a living and don't just talk to a camera
I haven't seen TIM degradation like that before. Crazy. One thing: How is it that this client bought a 4770 from you only 6 months ago? Selling old system? I guess that's the danger of second hand system with unknown history. Really you should never have to delid to maintain stability, unless you are overclocking by a decent chunk. Intel took a lot of flack for their crappy TIM. But the TIM does the job they needed it to. One of the reason that we hate it so much is that it doesn't transfer heat as well as some after market types or solder. But the reason it doesn't work as well is that it's formulated for longevity, no ultimate performance. Aftermarket TIM is usually rated for 2 years, Intel's was 10. Just a tip. It's good to check the per core temps to see if your thermal paste is making contact. If one core is WAY off (like 5C+) from the other ones, you might have an interface contact problem. It is normal to have 2-4 degree variance.
My 1300x was hitting 3.1 at 1.37 volts. Base clock is 3.5, turbo to 3.8. I had to update BIOS, update chipset driver, ect. Turns out it was thermal throttling cuz one of the cooler screws was loose. Once cooler was on it turbo to 3.8 at 1.2 volts.
I bought a 4670k for parts from ebay. the cpu would behave work, then slow down, then crash. 99ºc on 2 cores, 70 on the rest. Delided the thing, replaced the intel shit TIM with what i had on hand, Noctua NT-H1, used it for a few months, no issues, sold it for 70 pound profit. xD
wow...just realized why Intel swapped to using TIM instead of solder. Forced obsolescence. That's why they're doing it. We all know the cost difference is marginal.
Can someone help me out i have a wierd tdp issue, so im using the same i7 4770 and my cpu doesn't go over 60w on gaming, blender and benchmarks it only goes to 80w in high power test in prime95. I have changed bios settings to lower the temp with changing some settings thst i dont remember. But now that i have loaded optimized settings it won't go above 60w. Also the clock re fine 3.9ghz on single and 3.7ghz on all at around 65 max. If anybody knows anything about this that be helpful
Ok I'm done with these guys that think the TIM is "so bad" when they see it's dry after a delid. That stuff is obviously not meant to be exposed to air like that, no shit it runs dry. Yes, the Intel TIM is bad, totally agree, but this way of thinking is just wrong. At least it's not like that LTT vid where they scrape off the TIM from several CPU's and try to use it as a IHS-coldplate TIM. That vid was terribly bad lol
My first pc was a Q9550, I picked the parts but had the store build it. Once arrived it worked but not great and had higher temps and seemed to thermal throttle. In transit the cpu cooler must of been shaking because the thermal paste was cured with airgaps on all but the very center of the cpu. Cleaned it up and new paste and it was running normal. This system also had the OCV-Reaper 1066ddr2 that would cause issues on stock volatages or if placed in certain slot combinations with bootloop.
On a side note to whoever reads this comment: nowadays every cooler out there will come with some sort of pre-applied thermal compound which most of the time is $0.10/g crap (some coolers do come with decent stuff so do your research if you can). I recommend everyone to scrap that white stuff off, get yourself some decent thermal compound like Kryonaut or MX-5 (if you want more longevity but decreased performance over Kryonaut) and replace it, your temps will probably be about 5C lower. Plus it will probably last longer unless if you're constantly running 80C+. Kryonaut's break-down point is 80C, MX-5 *should* last longer in a high temp scenario but will not offer the same level of performance. There are more expensive solutions that might endure longer than Kryonaut in a high temp scenario but I personally think that by the time it starts losing effectiveness, your system will also need some cleaning, so it's not hard to also repaste at that point. On GPUs I highly recommend to test it on day 1 and then straight up repasting with Kryonaut once you're sure it's working fine. You will get better performance after the repaste, specially on Nvidia GPUs with the way GPU Boost works. In my case, I use a slim gaming laptop as my daily, my CPU (i7-8750H) runs 80C+ under load and these high temps lead to the thermal paste to break down/dry out faster than normal (I use Kryonaut). So I just replace the thermal paste whenever it's time to open my laptop to clean dust build up, which I probably do every 3 months or so. Every slim laptop I've seen out there running an 8750H will inevitably CPU thermal throttle at some point due to design limitations, so every degree counts if you want max performance and longevity.
All my io and gpu output keeps turning off randomly, stress tests and games don’t seem to make it anymore likely to happen. Replaced mobo, ram, gpu, no change. Sometimes it won’t boot until I change out random parts after the crash, doesn’t seem to matter what part as long as something changes. Windows event viewer shows nothing.
DOnt know how this is related to cpu.... When im usign LIVE LINUX from sub stick i almost always get the same freeze as you get here. But NEVER with installed os.
When I was in China not too long ago I got a 2nd hand AM4 A6 9600 that only does single channel mem which I did not realise until much much later. Also had a E3 1240 V2 xeon that will run perfectly but once you shut down won't start back up.. in the end had to drive to the shop in Shenzhen electronic plaza before they reluctantly offered a replacement. I'd imagine it's much of the same on aliexpress so always always test with dual channel mem and integrated gpu if there is one, then aida64 test overnight.
I just built my first pc from NZXT BLD KIT and it’s turning on but no display :(, I’m starting to think that I accidentally bent something from the amd cpu
I have a faulty 2500K and a FX-8230 that doesn't boot at all. A friend of mine has a FX-8350 that has one problematic module which only runs underclocked
Do you know why my prossessor keep broken. First one is athlon 200ge suddenly broken in the middle of gaming only 5 month use. Then change to ryzen 3 2300x. Same thing happen only 16 days use
I might have a faulty 5600x as of posting this comment my CPU workes fined till I put a load on it. The moment I play a CPU intensive game I crash or any bench marks / stress tests aimed at the CPU.
Well I have a dead 2700x was tinkering with vddp (trying to undervolt) and had a slight oc on RAM on a gigabyte x470 gaming 5, when it restarted it went black screen and now the CPU led is lit (in a bad way LoL)
I keep saying that the reason INTEL used paste between the lid and the die is so the CPU will run so hoot after a while , and most people will think the CPU is busted , but noooo a lot of INTEL fanboy's including some jewtubers keep saying "it's because they can't solder it because the die will crack"
hmm cpu is overheating, lets overvolt :D. Actually the only good way to test cpu if its faulty and not overheating (well that's obvious) is to swap to another test bench and then stress test it, also overclock it by 5% before testing, so u will know that it has 5% extra frequency stability margin. Also if underclocking cpu 5% helps , that still could mean that mobo mosfets are failing and some times provides less voltage than cpu could handle without crashing. An actual reading with osciloscope , by connecting to right pins could also show how bad the delivered voltage fluctuations are on problematic mobo.
you shouldn't use prime95 anymore it is known to overstress things to the point where it will break shit that's not broke lol need more proof ask Linus that's where I learned that from
Hi, I'm researching my own faulty cpu after having to fix many other system issues first. My Ryzen 3700X has a worker fail on the start of running a Prime95 test. The manufacturer suggests I change all my hardware to test and seek the help of friends etc to help complete my tests, well this simply is not an option, my hardware has already been changed many times for other system faults. Time and hardware cost are getting very high now. If the manufacturer cannot advise me on a simpler test option without the need for a lot of hardware swap outs then I have got a problem I cannot diagnose easily. My cpu is still under warranty and the retailer has been very good with other hardware returns, but I feel like the manufacturer should step in on this one and help me out more. Yes I may be able to under volt to fix the issue, but I feel this cpu should be rock solid on default bios settings and that is what I have paid for. If you have any input on this that would be great to hear.
I have a xeon based off haswell thats been beginning to run hotter and hotter. E5-2690 v3 12 core 24 thread beast got it well over a year ago off ebay for 490$. I changed paste on heat spredder tried 3 different coolers no change. Think this is same issue on xeons?. I dont dare try to delid myself since to this day this cpu is still very pricey.
My recent cpu broke, it was an X3440. Didn't know the reason why. But I knew it was a faulty one because there was no contact=no heat. Then changed the cpu to an x3430, then my pc posted.
