Recently purchased an AMD Phenom ii x4 975 as an upgrade from my old dual core, as well as a Corsair H60 hydro-cooler (as I don't have time to configure a liquid cooling system myself)

I'm using an ASRock 970 extreme3 motherboard on it's most recent BIOS version.

I'm very new to overclocking, this is only my second time doing it so I do need a bit of help catching up with all of you expert overclockers.

I have tried overclocking to 4.32 ghz (which is as high as I'm comfortable with going right now).
I set the frequency multiplier in BIOS to x18 (to acheive 4.3 ghz) and tweaked up the voltage from its default (1.35) to 1.45v. (maximum is 1.55, which I don't like going anywhere near).

Windows will load, but when I test for stability in prime95, it blue screens as soon as the testing begins.
Right now, I'm overclocked to 3.78 ghz (default clock speed is 3.6) and Prime95 has gone through 8 tests with no errors.

Again, I am a novice to overclocking, so be kind lol.

Thanks in advance.

Have you read the AMD black edition overclocking guide ??

Are your memory timings set on auto ??

Here is the guide :- http://www.tomshardware.com/forum/274820-29-black-editi...


I didnt know such a guide existed, I'll check that out. and yes my memory timings are set to auto

@OP
Man, no matter how you try...Maximum safe OCing for all the AMD Phenom II CPUs is 4.0-4.2 GHz...anything beyond that will be unstable and will require you to have a custom cooling system.

You should be able to hit 4.0 GHz easily just bump up the multiplier only and increase the voltage, as you said above it's not recommended to go beyond 1.5V a lot of users hit 4.0 GHz with 1.47 Vcore my PhenomII X6 runs @1.5V.

set your ref clock to 200MHz and just bump the multiplier, voltage increase when needed, but yes, 4.2/4.3GHz is as far as most 975's go,
mines special though :) ,

and I'm on water so the coolings much better, but most 975's seem to top out at 4.2/4.3
@ilysami, loving that avatar bro :)

Oh yes, I know the tweaker, as a matter of fact someone posted here not long back saying they had found a strange Cpu, guess what it was?
Jammy git lol
