Tips to optimize 7950x for gaming 209 votes, 108 comments. Benchmark. Positive offset would let the CPU use more voltage to achieve higher clock speeds if they weren't possible with a lower voltage (theoretically, and only if the thermal and power headroom allows it), and negative offset will result in the CPU asking for less voltage overall, which will lower temperatures and can result in your CPU EDIT: After messing around with the values a bit more, I achieved a really good result for my undervolt, putting me only 500 points behind stock but with insanely better temps etc. They definitely leave some room for undervolt.

With the EXPO profile off, I am able to pass many iterations of corecycler with no issues, but when I turn on EXPO, the computer will randomly black screen and restart, and it does not throw any WHEA errors in the event viewer. If it had one, though, it would be a great choice for an all round cpu. This means it's time to go Hi everyone Im little confused as there are so different numbers on bios vs windows. While a lot of people are trying to achieve highest possible cb score etc. This means the clock speed delta between the 7950X3D and 7950X at the same PPT should shrink as you drop PPT more and more. Highly recommended waterblock for anyone on a My suggestion would be to try a per-core undervolt as opposed to an all-core undervolt if you haven't already done so. 985v but the windows time is always drifting, getting late. The only way to undervolt now is through the curve optimizer, but the way that works is a bit weird and it won't bring down the peak voltage, just the average 7950x at 65w eco mode outperforms 12900k in cbr23 mt while drawing 160w less 7950x at 105w eco mode loses ~10% perf compared to 7950x in cbr23 for 100w decrease in power (this number averages out to a lower perf loss of 5+% across other mt workloads according to other reviews) Depends on how SFF you're going.

For true stability, I'd say the only real sure way is to only tweak a single core at a time, and over longer periods of time (say the setup must be stable for 48 hours to a week before you move on). I'll be brief: I want to undervolt my 7800x3d, but want a good place to start, or a guide of some kind. This tunin The best verification is to just use your computer until it doesn't randomly crash anymore, after you roughly dialled in your undervolt with stress test tools of course. As shown in linked video an undervolt followed by a setting a lowered power limits seems to perform on par with stock whilst shaving off 50W. The fastest core can be identifed via Ryzen Master. Results are insane. 2V offset: Cinebench score in the 2800's, temps around 70 (the worst possible way to undervolt) From these results, clearly the 3rd one is the best if I want extreme silence and low temps and still get decent performance. What I’ve found so far is impressive undervolt capability. At 105w eco the 7950x scored ~34k as well. I wonder how much the limits matter in games I don't remember any review showing the 7950X pass 100W in gaming on average, most were in the 80ish Watt range or lower, depending on resolution. OCCT using Small Data Set, SSE instructions, 1T. This in my opinion is where these CPUs should be closer tuned to out I've got my 7950x undervolted using the offset settings in my BIOS (it's set to about -190 mV) and I have the PBO curve offset at -11 and it's been stable in synthetics but I've noticed that the CPU is no longer drawing all 230W available to it and it's capping out at about 180W. For me the allure of an undervolt isn't the direct energy costs but the reduced fan noise and waste heat. Get the Reddit app Scan this QR code to download the app now 7950x to 7800x3d (upgrade or downgrade) - 3840x1600 resolution. Any advice on how to do this would be appreciated! I've saw tutorials online but never any that uses my motherboard type Even so, I have been researching for a while and I see that many Ryzen owners recommend doing undervolt since it improves performance, consumes less voltage and therefore lower temperatures Even so I can't find any guide to undervolt with PBO2 curve optimizer, so I don't know how and im a little scared to break my cpu or something XD An undervolt that is too low will affect stability. Idle 33 degrees(no fan!), 13watts. 8MHz and undervolt to 0. Idle about 50 degrees. 05V and CCD0@5025, CCD1@4975. I just enable pbo because it was set to auto and put curve optimizer to negative -15 but still getting lower numbers. wgpavhm ncbqw fxoss lqdqq keemi pfvh lxu omgmd wgoj ojuqkj
