AMD Fx-4300, it comes stock at 3.8 Ghz. I'm running at 4.6Ghz on a Gigabyte GA-78LMT-S2 mobo. The processor is stable at 4.6 and even 4.8.
The issue is when I run a program or game, it just sticks at 3.9 Ghz and never goes above despite it being set to 4.6Ghz in the BIOS. I've actively monitored it on CPU-z while playing very intensive games. and it stay at exactly 3.9 Ghz with a 19.5 Multi. Rarely will it jump up to the full 4.6 Ghz.

Even under full load tests, Novabench, it rarely goes over 3.9 Ghz and when it does it only does it briefly.

I have the voltage set to 1.5~ for the O/c.

I also have Win7 set to performance over energy saving.

Even under load the temps never get above 30c , it has good circulation and is liquid cooled.Specs.PNGwin7 settings.PNGCpu-z.PNG
