in this video I conduct a lot of experiments on computer hardware, in particular on old intel cpu. for example, I heat them up with a Gas Torch, scalp the processor with solder and much more
Those capacitors are not only filtering, but they have a special purpose. If there's a sudden increase in power consumption (can be going from idle to a cpu stress test) the motherboard will not be able to increase the power on time (and the physical distance between the VRMs and the CPU cores matters), so those capacitors act like batteries, which are phisically near to the cores, so that they can cover that power increase until the motherboard power arrives
so what might happen if you suddenly have a spike in cpu usage without these capacitors? would it blow up? just stop working? Im very curious to know if this would fail, and HOW it would fail.
Those specifically not, those are for when there's a sudden change in the current (for example going from idle to a stress test), the electricity can't physically get there in time, those capacitors act like "batteries" that are physically nearer and can power the CPU on time. If he tries to go from idle to stress without those, probably it will bluescreen or turn off because of CPU undervoltage
@@santiagobarrera2387they seem a little bit small to be able handle any type of suddenly demand. I think they are some type of filter capacitor to get noise out. Last line of defense kinda thing.
@@BVN-TEXAS When such spikes are nanoseconds in length, it's a lot. They aren't designed to decouple power supply ripple but the high frequency transients from the internal transistors switching on and off.
Obviously the translator didn't fully convey how intelligent or lack of in this individual. I don't see why this comment isn't higher up, had to dig for it since I knew it was here.
This man basically proved that while sure you should be careful with your components, first time builders do not need to worry about breaking something as easily as it may seem. Hell even I myself is pretty impressed with the durability of these fossils.
why do they always think pulling it out while it's running will kill it all it does is the same thing as turning the computer off sure the system will crash due to no cpu or ram but it runs fine after you reinstall it
@@SaraMorgan-ym6uewell yes and no. Primarily in laptops, if you happen to disconnect anything while the battery is still plugged in, the chances of sending the 19v (main power line in pc laptops) directly into the cpu (1v) killing it instantly. Its because the desktop atx pc's are meant to be modular, which is why they are so idiot proof.
@@nikitazaycev8636its actually because of the power supply. A good quality power supply has overcurrent and power surge protection. jayztwocents made a video about putting water on a pc, the psu will auto shut off and refuse to turn on until its been cut off from current for a few minutes. Not all PSUs have this capability, which is why you should always buy C tier or higher PSUs.
all these ways were dumb. first of all old cpu's. i didnt know about the caps just fore current regulation but you would do none of this damage in reality. Bent socket pins is 1st problem. Most Mb's have protection but in some cases you could push the voltage above what it can take but idk my z77 had max 1.57v and i tried that at 5.2ghz on a 2600k and it wouldnt die no matter what. 1.52v daily driver on (4,8x4 5.0x1) now im driving r5 5500 on 1.408 lets see how it survives. The capacitors on new cpus gpus etc are way smaller and you can knock the off pretty easily and wont even notice is gone. this can be soldered by anyone the ones now are as small as a grain of sand what are you about? Also i think people short the MB to the case way more often then any of the complicated things. Look at a cpu power connector and an 8pin for gpu switch them around and cya. Most thermal shit and deliding n shit is pontless unless you bought a used budget cpu and have no other option cause its shit and you have no more money and a well placed fan is better anyway. like i see this as a po0ntless video it had nothing just destruction. just the deliding was kind of interesting to see that it didnt matter but cracked pcbs is nothing new
@@marisbarkans9251 you did read that I said "fossils" pointing to the specific components they used in this video right? Of course nobody could re-solder a capacitor that small, nor correct a bent pin unless they have the precision of a machine. As for feeding your CPU a lot of voltage for giggles, I'll leave that to the LN2 overclockers. Lastly, if you by some odd chance manage to feed a PCIe power cable into the CPU connector, I'll have to applaud you. They are keyed, and in most cases labeled as well, for a reason. :)
Capacitors are for voltage stability so when an area of the chip needs a sudden burst of current, the current reserves are there in case the VRM on the motherboard isn't fast enough to keep pace. They help keep the voltage stable for sudden millisecond spikes in current draw.
It depends on where you drill the hole through the substrate, as long as you hit just redundant pins like how most of the power pins are redundant the CPU can run with a hole through it
Watching him scalp an lga775 processor expecting to find cheap thermal goo underneath the heat spreader was fun... Intel sure fell off since back then XD
Very good video idea, it's a lot of fun to see you torture those poor CPUs 😅 I'm happy to have discovered your channel, the editing is perfect, the thumbnail too, it's impressive for someone with so few subscribers! Keep it up 😊
I’ve had an Intel 3.4ghz Haswell in a 2013 iMac transcoding and encoding videos for about 8-9 years now, nearly none stop (queue in handbrake for days), just sitting at 85-95c (iMac). About the time it gets done a new codex or video standards comes out and I’ll redo old videos so it’s a never ending process. Point is, CPU’s are very very durable if just used normally. Can’t help from laugh when I see someone worried about their 70c CPU temp.😂
Loser temperatures surely are better there a known Casey oft gpus dying because of lackluster cooling and you never know what kind of silicon you really have. And also i guess the temperature sensor is not able to meausre the whole chip. I am not sure how severe these effects are but i guess you chip Holding up a long time can not represent every processor.
I believe these are decoupling capacitors, which keep the CPU running if your power supply has a small hiccup. Think of these capacitors as suspensions for your CPU's power supply. Aside from filtering voltage, I think they also help your CPU maintain power in between clock steppings. Let's say you take your CPU from idle to full load, like maybe you opened Crysis or something. The CPU would want to increase its clock speed, which would increase its power consumption, which means it would want to draw more current from its supply. Thing is, when it tries to suddenly draw a lot of current, the supply voltage droops. If the capacitors weren't there, the CPU could lose power as it was trying to step up to higher clock speeds. So my two cents about the capacitorless CPU is that, while it may seem fine as the computer boots up, it will be more susceptible to brownouts (loss of power). If you used it for a while, you would see your PC randomly shut off, especially when you put some strain on it.
Definitely familiar with taping LGA77x contacts - back in the day people would mod LGA771 Xeons with tape and run them in LGA775 sockets for a cheaper alternative to Core 2 Quad
And of course, overclocking without the overclockable motherboard. From 2.4 like Q6600 to 3GHz. I do really miss those days.. and even i remember overclocking with graphite pencil, AMD AthlonXP, when you shorted some contact pads with pencil, the clock multiplier was somehow open and free to be adjusted.
The caps maintain supply to the cpu and stability. You may find with heavy cpu usage the system will keep crashing if caps are removed and the same if many power pins are covered.
I had a Core 2 Quad overheat at 95-100°C under any load for a long while because I was a kid who couldn't be arsed to spend a couple coins on fixing broken cooler pegs. It lasted half a year or so before it finally gave up. CPUs are quite hard to kill lol.
THIS is what I was looking for. Especially sillicon grinding one. I'd do 1 more test: connect a CPU to external PSU and give it like 1.5V. Then check if it works. Keep increasing the voltage until the CPU is dead.
We had an old computer back in the early 90's can't remember what socket type it was. Anyways I was playing around with the cpus and swapped one out. I had no idea about the marking but I inserted the cpu the wrong way. When I turned on the computer a puff of smoke came from the cpu and that was it. Good times.
I always knew that by damaging things you also learn. Although in the learning process, my parents punished me for disassembling electronic devices. But that same curiosity led me to be one of the best electronics and computer technicians today.
The sanding of the silicon is actually used by some mad overclockers to get a better heat dissipation (less Z height between the CPU die and the cooling solution).
Had an AMD CPU once with a corner broken off its core. It ran 100% stable but couldn't show any kind of pictures - they just showed up as black/purple dot noise.
i actually dellided a xeon e5472 with a hot air station, was already 775 modded, and put some lm on it, the results were actually jaw dropping, 32 in idle and 70 max whilst playing world of tanks at max on a P43T-ES3G MOBO with modified bios.
I don't think the tape is fully preventing electricity from getting through. There might be a bit of current that gets through and as long as the relative pins are all blocked similarly, I think it is just recognizing that like an undervoltage or lower signal (compared to no signal as intended). Just my guess. Also, any capacitors are going to be able to store energy. I would imagine they're going to be used to handles fluctuations or filter the power when changing frequencies/under loads. Just my guess. Cool video tho. I can honestly say I did not know some of that stuff lol
at the start of the video, i had no clue you were using an english translator, about one quarter into the video, i was very confused by the strange language, then i saw the cyrillic on the computer, amazing work from the translator, but obvious he doesn't know the inner workings of a computer
Fun fact: if he shortened just a few right contacts he could force the bus speed to go higher and literally OC it. That's how I got my Q6600 running at 3Ghz in HP OEM mobo that has no settings for OC
I just catagolized and tested my 775 collection, cleaned every single CPU and it bleeds my heart how brutal you engage to these nice little things. However, very interesting how resilient they are in some cases. Now do it again with all your Quad Cores just to be sure the results are the same. :)
This is by far the funniest yet very interesting computer video I have ever seen :) I boiled an sd card once and it works fine to this day. The card is a whopping 512 mb one. and over 10 years old.!
After what I went through with my first computer assembly (woman, scared of hardware, always told by her dad not to touch it or else some capacitor will kill her); looking at this makes my soul scream in pain.
Powersupply is regulated but very slow. Its impedanze can't be changed so quickly. Thos capacitors are special ceramic capacitors with very low resisstance and inductance so they can deliver very high currents if needed. That helps stabilizing voltage changes. until the powersupply is able to "pump in more current"
I once had 2 bags full of 775 processors. it was years ago so when i've found a Q9550 working in there i was very happy ;'D Also most of them were q6600 and pentium's. Imagine testing around 300 procesors on 1 motherboard ;-; Bu tit was worth it, and i could do some experiments bc i had a lot of backups, ah the memories.
i think the CPU has those capasitors for speed and it still works because you either just launched in a wired way or it just used the capasitors from the mothorboard

What do you btw use for recording (camera,editing software,etc.)
