Everytime I set the voltage to anything higher than 1.4125v, the cores throttle down to 3.0GHz. All power saving features are disabled - APM, C'n'Q, C6, C1E or whatever its name was, Turbo Core is also disabled. LLC is on Auto, since I don't experience any voltage drops. The BIOS is updated to the latest F14b. It is not thermal throttling, as this happens even on idle. It just won't run at any higher voltage, regardless of the frenquency. Any help will be much appreciated.
Is just one core randomly throttling down.
Or all of them at the same time?
I am running a 990FXA-UD3 with a 8120.
I have it clocked at 4Gz and had the issue when running prime that one core would throttle down.
I use the Tip #2. CPU Load Throttling (Bios problem)
Get AMD Overdrive and Open and Enable Turbo Core Control then Push OK then Open and Disable Turbo Core Control then push OK then exit AMD Overdrive.
And it works.
How old this problem is I can't believe there isn't a bios fix yet.
