cant reach 4.2ghz why?

[immafrog1337]

for some reason when i overclock my cpu too 4.2 and i run prime 95 its crashes. all i do is change the multiplier and dont even mess with anything else. does anybody know why?

8 gigs of ram
i have a fx 8350
970 extreme 3 r2.0
cx600
h60

It fails in prime because you haven't changed the voltage.
In most cases, overclocking needs you to raise the voltage.

Having said that, I would not recommend overclocking on you board, as it is a lower quality board and may have issues when put under stress.

you did not changed anything else... maybe that's the problem. did you adjust your voltages?

AMD never guaranteed their CPUs to over clock.
Every chip will OC differently, the first thing you will likely need is a voltage increase.

even for a small oc from 4.0 to 4.2? and should i even oc on this board?

The motherboard has a 4+1 phase. It's already probably barely able to support turbo clock as is. I've tried on my extreme3 (non r2.0) and I'm able to get to 4.2ghz @1.35v, but my pc will crash after a certain point. You'll most likely need to raise the voltages to keep it stable, keep an eye on the temperatures to make sure they're not going too high.

OCing is trail and error.

You are getting an error, time to trial something.

As said, even CPUs of the same model/revision/stepping etc can OC with varying success.
My ancient Q6600 with a revision known to be not so good for OC manages to get from 2.4 stock to ~2.8 with LOWER voltage. Only if I want 3.2+ do I need a very minor bump.
