5950x curve optimizer undervolt reddit

The stock 5900X has only 142W power limit and 95A amperage limit which imo is way too conservative. Run the test for 3-5 minutes; if it starts throwing errors, dial down your curve amount by 1 or 2, and repeat (Core 2 and 3, to Core 4 and 5, etc). A good core might have, say, 1350mV for 4600MHz, while a bad core might have 1400mV. 2093 release highlights: Adds support for Desktops utilizing AMD Ryzen™ 5000 processors. 35v safe 24/7 or should I stay at 1. Version 2. Now these perfectly sufficient temperatures are ONLY really possible if I override everything with a Ryzen Master profile at CPU clock speed of 4,400 and CPU voltage at 1. Usually your 'best core' and 'second best core' as shown by Ryzen Master will need to have less negative curve applied, and the rest of the cores can have less voltage (so higher negative curve optimizer value). I have two options. Benchmark. Settings ( I think matter ): pbo manual: 138 - 95 - 120. Yeah the other cores are able to undervolt more and still hit 5050-5100 stable. 4v is fine at idle if its on auto and not manually set. cap temps at 85c in bios. EDIT 2: I found out how to run curve optimization from the Ryzen Master advanced menu and see the extra information. Running the Blender benchmarks I get multi-core clocks around 4400mhz and temperatures between 78-86. Now the auto optimizer says it will take 4 hours not a little over one hour. Ryzen 7 – eight, two fours, four twos, eight ones. Really great temps and decent scores but had an outstanding question: is it better to use the offset CPU voltage or better to leave that auto and focus only on curve Optimizer offsets? Without the CPU voltage offset, I could take get my CO nearly to as good of negative curves and the heat was much higher, too. 5ghz @ 1. Started at a negative offset of 5 on each individual core. The max temp under load is now 72C and is around 10C cooler while gaming. i have cinebench r23, occt, and corecycler to help dial in this undervolt i'm going for with best performance possible but lower temps since my ambient temp is always a constant 30c and can go up to 35c some days even when its maybe I did it on my 5950X on a per core basis and it took me 6 weeks to sufficiently test every core for stability. The previous pbo wasn't stable although it seemed like it, now I'm running at 200PPT, 137TDC, 165EDC. My original understanding was correct so I’ve removed the previous edit and strikeouts. From what I’ve come to understand, high end CPUs like the 5950x or even ones like my 5600x don’t gain anything substantial when overclocking for gaming. 2Ghz on all cores with voltage set at 1. 75 all core boost clocks and my temps hover between 66 and 70c for a full core load. PBO and Curve Optimizer are the way to go for gaming performance, along with RAM tuning. FCLK and memory frequencies are about the same. Someone post that a new version of ryzen master allow - 50 CO, but idk if it s a exclusivity for 7000 series or for. I was able to set the curve to -30 on all cores with 0 boost and be R23 and Prime 95 stable. Temps around 85c under cinebench r23. I would suggest leaving everything on auto and using PBO and curve optimizer, Ryzen is not really designed to be at a static voltage or have static clock speeds. I read the guide from katalysis (Guide: Zen 3 Overclocking using Curve Optimizer (PBO 2. 3 on a B2 5950X and the per core auto curve optimizer values were very low. Now i discovered that the CPU randomly throttles down to 0,54ghz for no obvious reason Looks like you have a very good bin! I think it's probably because the boost clock for 5950x is very high. However, I managed to get ALL my cores down to -30. Apply settings and get back to Windows. Your post will not be removed. EDC - 230. HerrSPAM. 85ghz down to 5. Testing new values at -25 with the CO.
