Hi all. I currently own an FX8120 on a gigabyte 990FXA UD3 mainboard, rev 1.1 bios F9.

Attempting to overclock I am having issues with the bus speed constantly underclocking and overclocking itself during load. I have everything that should adjust bus speeds and voltages turned off in the bios. I see people overclock these things to 4+Ghz, all I want is to be able to reach 3.9 or 4 myself.
CPU never goes over 50C, I just can't figure out what's causing the issue. Any help would be appreciated, or maybe you guys can think of something i haven't tried.
