OS: Windows 7 Pro 64bit
Mobo: Gigabyte GA-870A-USB3 v3.1
CPU: AMD FX-4100
RAM: 8GB GSkill RipjawX 1600
GPU: Sapphire Radeon HD 6950
PSU: Cooler Master Silent Pro M600 600W
SDD: 2x 64GB OCZ Solid 3 in RAID0
I am also updated to the latest BIOS from Gigabyte...
My issue is when I go to test my overclock in Windows using Prime95 with CPUZ turned on. I notice that my multi will jump between what I have it set at for the OC and 16.5 which drops the CPU clock to around 3.6GHz.
I've turned off:
Core Performance Boost
AMD C6 Support
AMD C1E Support
AMD Cool & Quiet
Thermal Control (I think that's what it's called)
I have all of these options in the BIOS turned off, and I've even installed AOD and tried the turning on and off the turbo button. But nothing I try seems to work. I've read other people have had similar issues with other Gigabyte boards. But nobody has yet had a fix for it. With this going on, I know I will not get the OC that I desire. If there is no fix for this then I will probably save up and get a better 990FX board from ASUS or ASrock I hear people are having great success OCing those boards with the new FX CPUs.
Does anybody know something I don't know? Is there another option or trick that I have not tried? Or did I make the wrong mobo purchase?
Here are some pictures of my BIOS and CPUZ:
As you can see when the CPU is pushed hard by Prime95 the modifier drops from x20.0 to x16.5.
