Heads Up! If your CPU is not boosting beyond 5.5 GHz when more than 4 cores are active, here's why: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-A8kf7Psn_Z0.html
I simply do not have the patience to do anything other than all core curve optimizer, I'd be pulling my hair out. Thanks for the interesting video though!
Hah, good point! When people ask my what's the appeal of overclocking (for me), I usually say it's like never-ending sudoku or 100,000-piece puzzle but with computer parts. At the end of the day, the situations where you get a tangible real-world performance difference are limited. But the process of finding the set of options that maximize the performance is somehow satisfying.
Great stuff. I might add that if at any time you have trouble with the BIOS itself locking up try powering down and holding the CMOS reset switch for about 10 sec to completely reset the CMOS.
I don't know what I did, but when I first got this CPU back in January, I tried to get the temps down without doing any research first and no experience with PBO. I remember setting all core to negative 25 and changing stuff I had no idea what. I started Prime95 and let it run while I left the PC for a while. Came back and the temp was still 95c. But what surprised me was that 12 cores had reached 6063Mhz! I took a picture with my phone to save as a trophy 😂
I don't know if it was just a spike or hwmonitor just reporting wrong, but 12 cores reaching that exact number, I guess there was something fishy going on. I later managed to get the temps down, but in the end I just decided to run it stock with PBO -24. It doesn't get that hot in games or my main productivity workloads, even while using an air cooler.
Hey my friend, I found a ‘core cycling software’ that use a power shell script to cycle through cores in Prime95 small ! Have you seen it ? It’s pretty nice I used to to stress test my PbO2 through the night. You can chose how long to test each core, how many loops to go through all cores individually and a cooldown in between each core. After the test is completed it generate a text file with the result for each test
@SkatterBencher I have a question about last year's "Alder Lake Overclocking: What's New (COMPLETE GUIDE)" video. At the "Specific Performance Core" settings I noticed you didn't set the highest "Specific Ratio Limit" on the 2 cores the bios identified as the best cores. Was that on purpose or just an oversight? And if it was on purpose, what is the advantage of setting the 2 best cores to a lower ratio? I'm using the guide to setup my new Maximus Z690 Formula and 12900K system. Great in-depth guide, it pretty much tells me all I need to know to have a solid starting point that I can tweak over time to match my hardware.
Would be interesting to see if you could make some content on how you keep Watt-consumption & Temps down, but still maximize performance to a certain extent.
I've been thinking about it. My challenge is that opinions about what's "too much watt" or "too hot" are all over the place. In addition, there's not much tuning involved in limiting watt or temp ... just set PPT or Thermal Throttle point to whatever you desire and that's it. So I'm not sure how interesting that is for people :)
@@SkatterBencher undervolting will get you lower temps faster than setting the thermal throttle point. What your looking for is the lowest vcore you can run at the highest clock multiplier and finding the sweet spot right where current/temps start expontentially rising, go back one setting. Worked great on my 3700X, 4.3ghz all core, stock cooler, never goes over 61C.
Great guide. Thanks a lot! Bios is now updated and with the whole agesa thing fix and there are a couple of extra settings in there. Are you considering re-visit this OC Guide with the current (more stable) BIOS? Also, about the current gpu limit, if there's a performance hit when jumping from PBO to manual OC, wouldn't be better to set the value lower so the jumps can happen when the system is about to get on full load? Maybe lowering the temp could be a good idea. Like 75°C or something like that.
Thanks for the kind feedback! I am not planning to return to Ryzen 9 7950X. I'm already struggling to keep up with all the different CPUs and GPUs ... I definitely don't have the spare time to do some multiple times :) Yes, you are right that one way to avoid the performance hit is to trigger the switch earlier. However, the performance hit will be visible somewhere else then (at those lighter loads)
@@SkatterBencher well this video is already very good anyways, again thanks a lot. About the limit, I found out that is not that good of an idea as I thought since the switch happens on mid loads wich are often very important actions on windows. I specifically found that lowering the value to let's say 150w at 1.23V (like using 120 on that current value) will negatively affect when my software saves or when some Nvidia softwares step in to do denoising something like that.
thank you for this. very helpful guide. it will be great if you can also add CORONA RENDERER 1.3 Benchmarks to your future test. corona is more widely used production renderer may be better than Vray.
Concerning CPU and mainly PBO/CO, I don’t see any advantages in terms of Bench (Cinebench) between stock setting and tweaked PBO /CO. I mean, I tried -10 on my 4 best cores, -20 on the others , Boost clock override at +200MHz, and I get roughly same Cinebench R23 scores than at stock. This is especially strange for single core performance where PBO / CO should help a lot. I have the feeling that currently PBO/CO and/or boost clock override doesn’t work or is not optimized. I am on bios 0805 with ASUS STrix X670E-E Gaming wifi My 7950X is SP117 and the cooler is 163 (H150i Elite Capellix) Windows 11 Pro 22H2.
@@jondonnelly3 Yes. In fact scores improve with PBO/CO as long as you have a good cooling. Mine is a H150i iCUE ELITE CAPELLIX and performs very well on my 7950X. I am currenty stable with following settings : PPT~TDC~EDC : 750W~500A~650A // Max CPU Boost Clock Override = +200MHz // CO : -10, -10, -10, -15, -10, -10, -15, -15, -25, -25, -15, -25, -25, -25, -25, -25. Medium Load Boostit is disabled as it is a no go for my CPU. Cinebench R23@20°C => 39500-39600 points Multi core and 2070-2075 points single core.
@SkatterBencher Ryzen Master is coming up with an optimized and stress-tested Curve Optimizer value of -30 on all cores (7950X) but I cannot go beyond -20 when setting this in the BIOS. Do you think this indicates a BIOS bug--perhaps some other settings (voltage, clock, limits, etc) are not set correctly in BIOS when enabling PBO? I'm thinking there are some default optimization settings that are compounding the issue which might explain why booting with defaults and using Ryzen Master to change the settings at runtime works. (Gigabyte B650 Aero G)
UPDATE: I can boot with -30 if I set a neg 100 MHz on the Boost Clock Override and I'm reaching my best numbers in PassMark (4384 single-core, 64609 multi-core).
thanks for this video. the more i see people extracting huge performance from a 7950x, i keep thinking mine is broken... I cant seem to keep stable with a CO higher than -10 to -12. when starting a superpi per-core test, to find the limits of each core for CO tuning, should this be done from stock BIOS settings? I currently have some PBO and CO adjustments dialed in, so im unsure if starting from here wouldnt be more or less effective than starting from stock. My goal isnt max power, but lower temps/voltages without crippling the cpu and making the fact that i "upgraded" basically worthless. i know i could just set a max temp limit and call it a day, but i think that leaves alot on the table as far as performance thats still untapped if the voltages are just applied more appropriately. also, are you familiar with PJVol's PBO 2 Tuner utility? I came across it in another video tuning a 5950x, and it seemed like a good way to dial in values, but im unsure if it will work with Zen4. Any idea here? I can barely find any info on it other than the original posts on overclock.net, and a few videos where people are using it on older gen CPUs. I asked there as well, but no answer.
Silicon lottery, its why im considering gettting the 13900ks as it means for sure it's a decent bin. It's does run a lot hotter in all core workloads but in gaming it''s fine.
@@SkatterBencher Thanks!! I was comparing both all of them and it came out that strix has 3xM.2 PCIE 5.0 x4 and 16xPCIE5.0 for GPU = 28 lanes - what is a scam and robbery on the GPU lanes :). I will go with Aorus Master - it is decent and at least you have 4 usable M.2 slots not robbing other important elements!! And yes!! Your meaning helps!!
I do not have 7000 series, but i played enough with 5000 series to be sure im not wrong what im about to say, and from reviews and even your video, the only difference between 5000 and 7000, is a higher temperature target set by AMD and higher power limits out of the box, and ofc higher thermal density since it's a smaller node. Increasing FMAX offset in most cases is uselless, this is because it will hinder your CO drop range. I havent tried it on water at high wattage and for multicore loads, but i dont think it's any different. That being said, most if not all ppl look at this the wrong way. You don´t wanna look at highest frecuency achieved, but highest avg sustained. If you're going for single core and gaming, depending on your cooler and cooling environment, you should decrease the FMAX offset, hard power limit the CPU, and hit it with CO. You should aim for 60-70ºC range under incomplete loads for ryzen 5000, or 80-90 for 7000, although i would recommend sticking with the 60-70ºC for ryzen 7000 for longevity purposes. For multicore, set power limits to "sky is the limit", and tune CO........ be careful here, as you might not be able to go so low like before, and need to stability test per core aiming for max clock stretch much harder as it might be unstable at idle and low intermitent loads. SSE instructions are my favorite.
Hi can you help, i tried with asrock b650e pg-itx and 7950X and ram g.skill trident z5 neo ddr5-6000 cl30 64gb, ram in on profile, if i go light oc no matter what I do is a blue screen, in master the same, all is on custom ek water. Thanks
Would you recommend using both low latency support and high bandwidth support if it doesn’t cause boot issues? Can’t really tell if they provide any performance change
I'm currently not planning any content with ASRock board. My 7900X and 7700X will be with ROG Crosshair and 7600X with ROG Strix. Then probably one more video with MSI before the launch of the X3D variants.
Heard from a lot of sources the Seasonic PSUs have the best quality. What is your opinion based on your experience ? I have the TX - 1000 model on my wishlist.
I'm not a PSU reviewer, so I can't give you an objective comment. That said, I've been using Seasonic 850W power supply almost exclusively for years and never really had an issue. Apart from that one time Threadripper tried to pull 1000W+ watt from the wall socket haha
No video with the 7950X3D, but I did do a video with the 7900X3D and Aorus motherboard ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-NzNflofJufY.html
first of all - great video , may i have qiestion to You ? i try determine curve for each core using Ryzen Master , i run this curve optimisation per core, ppl say its should take arround 1h 40 min, well after this time im stuck on 6-10 % for 2 hours, its any other tool which help me find curve optimize for each core ?
Hi, I have the same setup and I noticed some strange behavior with this CPU; when I use it in games the clocks are stuck at 5.5 regardless of load. Even in games that use less than 10%, it won't boost above 5.5. In benchmarks and the desktop environment, even at loads exceeding 15%, the clocks are around 5.65-5.85. Is it a bug or something?
You mean manual per-CCX overclocking? To have a starting point, run your heaviest workload/stress-test for 15min, then check the average frequency and average voltage. That can become your tuning starting point.
@@SkatterBencher Yes, I'm running a -10 CO now with PBO. Resulting in CB R23 scores of 38000-39400 usually. Could probably try -12.. - 15 not stable when Idle. Going to try a manual OC on all Core. And would like to know what to start with Per CCX. And voltages that I should aim for. I'm on custom watercooling. Watertemp around 30 celcius. Still worried about contact with the waterblock though. Might want to re-check it... But the CPU does work as it should in standard operations. Running CB R23 for 15 min. I see CCX0: 5.25 , and CCX1: 5,05 stable over time. All core boost on light workloads are 5,75hz on every core.
My B650 does not have Async/CPU/PCIe clock. Should I NOT touch the CPU clock control? If it's safe to increase it a little bit with air cooing. What is a safe increase? Up to 102? 105mhz?
I have not tested Sync'd Eclk on Ryzen 7000, but my guess would be that the range is similar to previous platforms that didn't have Async. So 103~105 MHz maximum, possibly as low as 101 MHz.
My Raphael launch content was with a 7950X (ES) and the X670E Gene. I also created a video with the 7900X and X670E Extreme. Maybe those are useful for you? ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-20r4NhtvOj8.html ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-y7FgijMlLc0.html ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-o_AMxVcS2DM.html
With money not being an issue at all, how do you feel about the Rog Crosshair X670E Extreme? I will add to the motherboard whatever 4090 I can get my hands on at launch and G.SKILL Trident Z5 Neo RGB Series AMD EXPO 32GB (2 x 16GB) 288-Pin PC RAM DDR5 6000 cl30 until I can get my hands on the ddr5 equivalent of my current ram. I am upgrading from 5950x/Asus Rog Dark Hero/3090 and 4 sticks of 16gb Gskill Trident Z Neo 3800 mhz cl14 ram which I was only able to get to 3777 but with ram timings of 14 14 14 34 so the system has been running very smoothly along with your advice on overclocking the 5950x. What will be my am5/ddr5 equivalent part list? Am I on the right track? Also with this motherboard, I should be able to like last time follow your instructions even though we are using different motherboard right? Sorry for the long winded message but I can't think of anyone better to ask these questions and hope very much you are doing well and want to thank you for your great and thorough work. I do wonder if another dark hero is down the pipeline, and if it will be better than the X670E that is coming, I got to say, it was on hell of a board.
@@BloodShotFury the memory overclocking capability was extremely weak. Barely able to get 6000mhz stable on Samsung or hynix ddr5 with multiple 12900k cpus. Zero advantage over a hero. Just big and expensive, but unlike some extreme boards in the past it didn't seem better. It feels heavy and nice but using it is a pain. Had many Asus boards previously and this was the worst experience.
I'd love to see you do this with an ASUS mobo, because MOST of these settings DO NOT translate into the bios of my X670 StrixE-E mobo. I have a R9 7950x cpu, GSkill NEO binned 6000 DDR5 and a Radeon 7900XTX gpu. So several of the settings you are using in the Gigb bios are not present in the ASUS bios, like the high bandwidth setting... Can we get some stuff with an ASUS mobo?
No, the 7950X3D works very differently when it comes to overclocking. I would suggest you check out my X3D video to learn more ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-9BwNt6PD-00.html
Hello, love Your work... please do not get me wrong, its a wonderful video, only thing is that nobody will ever buy a 16 or higher core cpu for a motherboard brand that offers one x16 pcie slot and not a second x8..... the whole reason 16 core cpus sell (bulk of them) is that they go on Nvlinked GPUs...no, I do understand that 4000 series Nvidia gpus do not come with nvlink, but for this reason 4090s as the 3080ti will not sell at all. and nvidia will for sure bring back nvlink to its 5000 series. So who is buying 7950X has typically dual 3090's. When Mind factory opened sales for the 7000 series, the MSI carbon X670E sold out within 10 minutes with just as many 7950X, in a total of 280 units...and they are left with gigabyte boards that no one is wanting to buy. I Would be very grateful if You could make videos on ASUS and MSI X670E motherboards, designed for 16 core cpus, and aside the cpu OC, see if you can OC and to what extent Hinyx 64 GB memory sets... pros and cons.. EG ASUS validated 5600Mhz Corsair memory 64 Gb. This OC tutorial or any Gigabyte one would be much more useful for 7700X or lower users.
I don't think Nvidia will bring back NVlink. You have to buy a Pro-Card (not called Quadro anymore) for that. Why? Because money and NV is all about the revenue. And thinking "no one wants to buy" you are referring to a very small number of people who work with a dual 3090 setup. And 4090 will sell, I have no doubt. I think you are massive overestimating the number of dual-GPU systems now / in the future. It was a small number when SLI was a thing and it will be even less in the future. So people who really work with them, will run Threadripper with not-Quadro-anymore Cards. Anyone else will either run one Geforce or pay for it. Why i bought this board? 2x Gen5 M2 Type 22110 and 2x Gen4 M2 Type 22110. So now i can run 4x 4TB Samsung PM983 without some stupid adapter.
@@derstreit You have no idea. You do not get phone calls from nvidia representatives sell you quadro cards...I do. at the top tier the number of dual to octo gpu systems outnumbers gaming ones likely 1000 to 1 and i tell you more, pretty much the bulk of 3090 or previous titans are all purchased by people who use at least two in their systems. These 40 series will remain unsold just as much as the 3080 ti...literally safe to say 80% at minimum will lie in warehouses getting dust and the 5000 series will have nvilink again. certified. No one buys quadro cards after windows 11, the only reason we purchased quadro cards side the memory allocation, was pretty much because of being able to run 10 Bit monitors, today you do not need that anymore, and for the applications we use to give you tv commercials or shows or feature movies, all we need is FP 16 and FP 32. The Quadro market is literally almost dead and is necessary only when using Dassault Catia when we talking 3d and 3d stress simulations and frankly You do not need Nvidia Gpus for that, You can very well use AMD, while for what we do for media and entertainment CUDA and Optix are an absolute must.
@@AbyNeon Jea, nvidia did not contact me, but i sold enough of their Pro-Cards in CAD Workstations I build. You are right when you say that most of the 3090 went to people with 2 or more. But those were miners. Jensen only cares about revenue for his shareholder and when nvidia sees an oportunity to milk some more money out of people, they will do it. nvlink on consumer cards is dead. Nvidias stance on this is ease: you have no choice, so give us more money. What will you do? Buy competition? Write angry letters? The 4090 will be sold, don't worry. Maybe not to you and the million of dual-card user that are seemingly out there. Maybe one to me, I have to see how much faster it is. As you said, if you need CUDA and Optix, you buy NV. And if they stop selling you consumer cards with nvlink, what will you do? You NEED it (absolute must, your words) so you pay for it.
I like using different vendor boards to have an idea what the experience is like. No preference in terms of brand (ASUS v Aorus) since the overclocking experience boils down to the specific motherboard.
Could you make a video with the asus x670e hero. I don't fully understand this bios. I can set the co to -30 without any crash, but the cpu stays at 5.2 ghz max during cinebench and 5.5ghz in lighter loads. My 2 best cores reaches 5.75ghz. I also don't find any expo settings on my bios. I've tried everything i just can't seem to overclock this cpu more than that Even set clock overdrive 175 and the thing is stable but will never higher clocks, i don't know why. I have a good aio. My cpu is cool during idle. And reaches 95c during heavy load
What BIOS version are you on? It sounds similar to something I had with another board where the BIOS had an older AGESA on it which didn't properly boost on retail chips. As for EXPO: do you have EXPO compatible memory installed?
@@SkatterBencher I've tried the original 0611 and the latest beta version and both seems to not actually do anything with pbo enabled It's like the settings with the beta don't actually interact with the cpu And the ram I thought they all were expo compatible. I guess not... in my country the stores don't say if the ram is expo or not I also tried the curve optimizer from ryzen master and the result is -29 for the co.
If EXPO is not explicitly supported (as in: there is an EXPO profile flashed on the memory), then EXPO won't show up. You might have other options like XMP though? As for the other issue ... strange. I will ping some people to see if this is a known issue. You can also consider trying the 0094 BIOS that Shamino uploaded here rog.asus.com/forum/showthread.php?130719-X670-resource //Edit: looks like 0094 might actually address this specific issue. Worth to try, I think.
00xx BIOSes are typically engineering BIOSes to test quick fixes. I'd try it to see if the problem is fixed and if so, report in the forum thread with your experience. It can help the ASUS engineers validate issues they don't see internally.
Is the point of using the asynchronous clock to have only the CPU be affected by the percentage increase, while leaving everything else at its stock value? Does this have the affect of limiting potential instabilities to just the CPU?
I know FIT but I'm not familiar with FIT voltage. What's that? LLC is kept on Auto, which on Ryzen 7000 series seems to be very high by default AMD auto-rules (LLC7 or so)
I have the 7950x and when I play cpu demanding games like warzone it runs cool like 65-80c when I keep hearing other peoples chip running at 90-95c!! I also noticed my clock speed is at 4500mhz. Is this how the card comes stock since it’s advertised at 5200mhz. What can I do to increase the speed of my card and have it work a bit harder? Through Ryzen master software I tried enabling OC mode and it was the biggest mistake as my monitor wasn’t booting up so I had to take out the cmos chip and do all this stupid stuff. Anyways, some help would be appreciated!! I’m thinking of enabling pob on my bios but I’m afraid to do it. Will it help?
@@SkatterBencher I’ll give it a go. Thanks for the video. Very informative and easy to understand. I’m all about simplistic teaching methods to help those new to all this understand meanwhile still teaching experienced tuners new things. You earned a sub.
@@SkatterBencher gave it a try and although my frames are def way higher, seems a bit unstable. A bit choppy and stuttery. It was a little smoother before even with a frame cap. Might go back and then manually overclock it by a little but that’s when I feel comfortable and learn how to do it properly
WARNING: When leaving the PLATFORM THERMAL THROTTLE CTRL in AUTO mode, I have seen Gigabyte motherboards (Aero G) allow the CPU to hit 118C and even beyond, hitting the thermal protection limit (not sure the exact value but somewhere near 120C I presume). While Ryzen Master will show a limit of 95C, this is somehow exceeded in some benchmarks--particularly PASSMARK's Extended instructions Testing (SSE), causing the system to immediately shutdown. However, when manually setting a thermal limit, I do not see this temperature being exceeded. I highly recommend setting a thermal limit. For daily use, I'm setting mine to 75C getting 95% of the performance with significantly lower power consumption.
To be more specific, with a 75C thermal limit, I'm actually still reaching a PassMark multi-core score of 62681 and single-core of 4253, so this seems like far less than 5% of a hit compared to my best scores of 64609 and 4384 when set to 95C).
It's an AMD Ryzen 7000 CPU feature, so it can be enabled on all motherboards. However, it requires an additional clock generator to be on the motherboard. So it will depend on the motherboard whether the function is available.
