Welcome to OCN. thumb.gif

There are no guarantees in OC'ing but there is likely some more room in your FX-8120.

Have you checked temps under P95? Have you run Memtest86+ from a floppy, CD or flash drive?

Have you read the FX / Bulldozer Owners thread on OC'ing? The FX CPUs OC a little different and the mobo BIOS is extremely important as the BD architecture is different from previous CPUs.

Turn off C'nQ, and turbo core.

Also turn LLC on ultra for "JUST" your vcore.

Then tell me what happens

I use high or ultra-high (I can't remember) and it makes it so that the voltage I set in the BIOS is exactly what the processor sees on idle and load.

Make sure to check your other voltages as well, not just your CPU voltage.
