Looks like I have to undervolt my PC but not sure where and how. Stable version will have a section called, "CPU Overclocking", click there, It has undervolting. So, it's been a little bit more than a couple hours, but here we are. 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 If you want - dial in a small negative offset on a curve optimizer and call it a day. start with i. I was getting 78 degrees gaming with it and around 50 on iddle. Set and forget is leaving it at stock. Here are my settings so far: PBO Limits: Motherboard. 25MHz // voltage ~1,2 // ~105W. Stock. On stock settings, the cpu goes 50-55 degrees on idle. So in the summer my CPU can get as high as 88°C under full load (CPU cooler isn't that great but can get the job done). Highest effective clock speeds. RAM: G. I have tried to set PBO -50 but it didn't help. Problem: I have up to 89C degrees while playing in some old games like Cossacks 3 and it's only 65C in Cyberpunk 2077. Temp: ~67C Clock: ~4560Mhz (all cores) Peak voltage: 1. CPU cooler: Thermalright x47 full copper. PPT 100 TDC 70 EDC 100 at -30 - From 5800X3D thread - Highest average clock, decent temps (78C with Power Limit causes the cpu to run slower with the default voltage curve, and possibly stuttering under spikes. Once you do this, boot into Windows, open Ryzen Master and start CB23 multi thread test. I could go +100 and increase my undervolt but the only benefit would be reduced power usage and lower boost clocks. 250V. 31134. The same happens with -15 on all cores. 2 (Non-advanced settings). 95V instead, and whatever frequency is mapped to 1V is now >2GHz. I enabled PBO and CO too in AMD Overclocking. Onyx : A MD Ryzen 7 7800x3d / MSI 6900xt Gaming X Trio / Gigabyte B650 AORUS Pro AX / G. The cpu itself could have been bad. AMD says Ryzen 7000 is designed to run at 95°C for 24/7. While the 5600x and 5950x were an all core negative offset of only -12. The second part of PBO, curve optimizer/CO, was added in Zen 3 as ‘PBO 2’. Easiest Method: Kombo Strike 3- Just go to your overclocking options in BIOS and choose Kombo Strike: 3. It's not impossible to run a -30 all core offset on a 5700x, just highly unlikely unless you have the "golden chip. #1. 142W PPT ~ 105W TDP. 1. I used Ryzen Dram calculator to manually set all my ram timings and I havent gone for a constant all core 24/7 overclock. 275V and All clocks to 4. PBO Curve: Per-core (-27 to -30 range -- Used Ryzen Master curve optimization with larger vcore offset until per-core offsets went slightly under -30, to understand relative differences between cores and then normalized to -30 range. In general I'd say it's worth it as long as the temps are reasonable. Obviously your ambient temps play a role, if your room is 12°C, you have nothing to worry about. so my cpu voltage was set to auto and it was going around 1. e best cores @-15 ,rest @ -20, run cb, use ryzen master,if ok, go -15 with -25 and repeat( those values are not fixed,they depend on silicon lottery, case, cooling,but are a good start). GPU: MSI GeForce RTX 4080 SUPRIM X. Ram at 4000/2000fclk 16-16-16-16-30-46. You should get better perf and lower power if the only things you did is pbo 2 curve optimizer and disable power limits, albeit -30 sounds a bit unrealistic for me. te mm fc wx xj zr qc iq na wv
