Stress testing or general usage. I'm sure extended stress testing may push it over, but I'm also not maxing my fans out either. So yeah temps don't really go above 70*C.

No idea what your setup is so no idea what to say about how to lower your temps besides the obvious.

all stock, jep looks my cpu is hot or is normal, depending on the room temperature, idle pc some daily use temps go 36-50. In game and streaming are spikes to 80, I have to continue slowly test cpu with some OC,...I'm still exploring CPU

If true, and your temps are good (below 90c), then yes. That is a good overclock at that voltage.

what voltages did you guys use to get 1900 fclk?







I am at 1.143 vddsoc/1 for both vddp/vddg, I can't get it to stabilize but the CPU will POST and boot with 1900





I read that there's a negative voltage scaling with ryzen tuning, so asking advice on how to proceed with tuning











Crosshair 8 Hero. motherboard vrm and switching (600hz) settings already maxed out

I'm in the same boat. Is there a 1900 FCLK guide? I know I'm working from a deficit running 4 sticks of ram but I get amazing results at 3733 and have plenty of thermal and voltage headroom.

so basically what I did to get 1900 FCLK, there's a lot of back and forth because there's negative voltage scaling with zen2







I put the motherboard vrm setting for ram and SOC to be extreme phase response, maximum current draw, and maximum swtiching frequency


LLC settings are 3 on CPU/DRAM and 4 on SOC




after setting fclk to 1900 I raised soc/vddp/vddg to: 1.2/1.15/1150, then manually set and reboot each time, if the reboot fails then I will try a lower setting (by one or two step for vddsoc, and 5 step for vddp/vddg)


eventually I settled at 1.09/0.985/985 for the final voltages that will allow me to run 1900fclk stable






So it went from being stuck at POST code 8D to POSTing with a beep to boot then finally stable, all through reducing voltages






I tested with randomx miner stress test app, it hammers fclk: https://github.com/00-matt/randomx-stress


All testing of fclk stability is done with 2133 stock jedec memory speed, after that I tested memory at 3800 and played around with ram oc




Not all chips can, it's the fault of amd not binning the IO die, tbh a fitting punishment would be a 9mm to the head of whoever decided this




Siliconlottery's stats on chips that can do 1900fclk without tweaking is very low

It is a little frustrating.... My 3950X is perfectly stable at 4.2ghz using 1.1875vcore and 4.258ghz using 1.225 vcore tested with Blender benchmark for stability but Prime95 also run without an issue. At 4.2ghz max temps around 76c while running Blender and around 82 to 85c while running 4.258ghz Blender. Now running CB20 under these conditions you look at 71 to 72c for 4.2ghz and 78c for 4.258ghz. Now I can go higher on clocks for benching and I tried 4.358ghz at 1.275ghz and it would give me 81c running CB20 so I tried 4.4ghz using 1.3375vcore but temps jump up to 92c while running CB20. Look I've had it before where my first 3900X can run vcore up to 1.375v and I will not see 90c but my second 3900x a better clocker but it would break 90c even with only 1.325vcore.

Hey guys,

got the 3950x recently for my new workstation (mainly using Adobe After Effects and Cinema 4D).

I now tried to overclock it a little with Ryzen Master and got to 4.1GHz with 1,1875 vcore stable and temps around 68°C.

But when I try to go higher eg. 4.2ghz with 1.35 vcore, the system instantly crashes when I try to run Cinebench R20.
Ryzen Master`s stability test goes through and temps at around 70°C.

Could anyone help me out here please?
Am I missing something?

Noctua NH-D15
64GB G.Skill NEO, 3600 CL16
