I recently got a 5950x and it's cooled by a Lian Li Galahad AIO. Temps are always good (40-65c). And it seems to be running fine for anything that is "normal use".
However, any time I run cinebench or 3dmark's cpu suite, the CPU immediately downclocks to 700-800mhz across all cores. There is no temperature spike - the downclock starts immediately upon the benchmark beginning. It will drop from 55c to 35c (which is lower than it normally idles) within seconds - so it is not heat related. I also checked my VRM temps, and those never get above 65 either. I can also run Prime95 forever without temps going above 70.
For some reason, the CPU just instantly downclocks to potato levels the second I begin a benchmark. Does anyone have any idea why?
I've tried changing PBO in bios to "motherboard" settings, and disabling XMP, but neither of those did anything. Like I said, it's performing great under normal use, but I worry that if it downclocks like this during a benchmark it might do it to me down the line on something else. Any help would be greatly appreciated. Here are some screenshots as well: View: https://imgur.com/a/hzZsgJE
