Every time i run an all core all thread load on my 5950x, the clocks drop to 546 MHz. X570 Board, 850 W PSU. Temps never get past 65, the AIO Is good and working, 360 mm rad 6 fans. Yes I know its inefficient, no i don't care. Had this problem ever since I upgraded from a 3700x. no problems with anything like this before switching the cpu. Bios and all drivers are up to date, I did a clean windows install as well. bios is 100% stock except fan curves and XMP. ive had this issue for 6 months now without being able to solve it, have heard it could be due to bugged bios or drivers, at this point i have no idea. please help

yea i thought for a while that it was my motherboard vrms dying

i thought that getting a crosshair viii dark hero with the goated vrms would fix it, but i havent bought one yet
