Complete OC noob.

Just bought a 7950 but im stuck with a 965BE for a while so i obviously want to push it to the limit.

From a brief read around i think i've got the basics of OCing but help would be great. Correct me if i'm wrong.

1. Start with the multiplier and ratchet it up in step, whilst keeping stock volt.
1.1- Test with prime95

2. Rinse and repeat until failure.

3. Start nudging the voltage up. 1.55V limit?

4. Push as far as your happy with. ~65C limit?

Is the RAM OC an analogous process?

Im sure ive forgotten finer details. All help really appreciated.

BTW. I've used the MB built-in OC feature to get 3.8GHz
 
Don't use Prime 95 on AMD. Use LinX. If it gets too hot it'll soon let you know by freezing or shutting down the PC.

The ram will be offset as soon as you add FSB, so just be careful to check what its calculated speed is and then change it to one you know will be stable on your ram. What sucks for me is I have 1600mhz ram and I either get 1464 or something or 1834, something like that. My ram will never run 1834 so I'm stuck at the lower speed :( I do recommend using the fastest ram you can on AMD as it frees you up to go mad on the FSB without sacrificing ram speeds.

You should get 4ghz out of that CPU. IIRC that was pretty much a given for those Denebs (if they're Denebs, I don't know if AMD used something else in the later P2s)

My old 965 would not remain stable above 3.8, but I never really tried that hard with it . changed it for a 980 ages ago and used the auto tune feature in AMD catalyst control centre and got a rock solid 4.4 albeit with a load of volts . settled in the end for 4.2 with 1.48 volts.
You could try setting your CPU to stock and give AMD overdrive a go, it would at least give you an idea how far you could push it.

Thanks guys,

Yeah, these auto clockers. I always wondered how close to the upper limit they actually get.

They just shove up the voltage as high as they dare and give you a lame ass clock. They have to, they have to make sure it will work 100% over any 965 (if that makes sense).

It's always advisable to go in there yourself and get your hands dirty. I'll admit on my Crosshair V FZ I let it do most of the work, but that's a thoroughbred overclocking board so doesn't pay caution to the wind :D
