Ryzen 5950X low single core scores in Cinebench R15&R20

Low single again , hope your next bios fixes that.

My settings:

PBO with motherboard limits
CO -10 (positive offset 0.03125 just for safety, bellow -15 needs too much positive offset to be stable seems CO brings voltage to low at higher settings, still using the Arctik 360 cant handle 240w too well)
Scalar X10
+200Mhz
LLCs set to Extreme, 350
Everything else on Auto.

I have an ASUS Strix X570 E motherboard, so I am not totally sure your board will have the same settings, but if they do then do this and it should fix the scores. It did for me and I was getting way below the multi and single threaded scores I should have been, now I am in line with what reviewers are getting.

Search the BIOS for the option 'Performance Enhancer' and set it to default. BIOS default setting puts it to auto, which seems to do something terrible to voltage and causes CPU to throttle clocks. Next setting is PBO Fmax Enhancer, which I disable. It seemed to lower my single core score with it on auto or enabled. Once those two settings are set correctly, the only thing I did was put PBO to enable, set Max CPU Boost Clock to 200Mhz and enable DOCP so my memory was running its rated speed. All other settings in the BIOS were completely default.

I hope this works for you like it did me.

Thank you!!!

That gave me another boost . Asus does suck ass bios wise, when you have to disable "performance improvement options" to get better performance

PBO Enable motherboard limits, CurveOptimizer set to -15 on best cores and -10 on rest, +100Mhz, Scalar x4, LLC set to default, voltage set to auto, Performance Enhancer - default, PBO Fmax - disable.

PBO 300/220/240 limits, Curve Optimizer set to -15 on best cores and -10 on rest, +50Mhz, Scalar x10, LLC set to default, voltage set to auto, Performance Enhancer - default, PBO Fmax - disable.

And finally some good results without overclock or voltage. Cant wait for the cpu block to arrive to see what this CPU can do with a sub ambient chiller cooling

Hah 4 days you say, I got the CPU on launch day, spent over 20 of the 25 days...... Finally I am happy, it was a struggle when no one else got my config to start with. This mobo has seen more resets then seconds in a hour . This CPU is unbelievable compared to my old 3950X, I browse, render, play an AAA game in the background and some youtube on the side. Hope to get 5ghz all core with some proper cooling, then it will be full happiness .

Finally I am a happy bunny

Could not wait anymore for delivery and got a very cheap chinese water block, together with my 1hp chiller, results are promising. Everything on AUTO+PBO+CO -10

I have shared all that works for me . I am also selling my 5950X got the 5900X instead. For my work 5950X is too much.
