What's the better way to OC this CPU? (965 BE)

post #1 of 18
Thread Starter 
Ok, well I'm a tad noob when it comes to OC'ing, I don't have the comp yet, but it has a 965 BE, liquid cooled. Would it be better to just raise the multiplier and then raise voltage when it gets unstable with the multiplier? That i know how to do, but the other way just plain confuses me. The way when increasing the fsb. So if i increase the fsb past 200, it's better to keep the multiplier lower? Also, the fsb impacts HT and the NB. I'm not sure what to set the NB to, or even what the NB impacts lol, I feel it has to do with ram. Is there some tutorial explaining this other way of OC'ing?

It's a black edition so there's really no reason to use the fsb unless you are fine tuning it.

If you have a specific clock speed in mind, set it at that speed and raise voltage until it becomes stable in Intel Burn Test etc, OR until the voltage hits 1.5, whichever comes first. Then stop.

If you just want to see how far you can go, set the voltage at 1.5 and start raising the multi. Once it becomes unstable then drop the multi back one notch and tweak the fsb until you reach the stable limit.

Very true, the 2nd way is kind of unnecessary for a BE, but i'm interested in maintaining the life of this cpu, is 1.5 the final safe vcore? I was planning to see how far it'd go on stock voltage, i've heard around 3.8ghz, but wanted to see for myself

At no more than 1.5V you should be able to get 4GHz. As long the temps are well within limits with that kind of voltage, the chip should run for a long time.

Black edition, can use the multiplier to OC. Knowing motherboard can also be useful with knowing overclockability.

Ok that's all good to know thx, and I think i've read somewhere don't let this cpu reach above 65c, is that correct?
post #7 of 18
Do try to stay under 55C however, max rated is 62C.

55*C and 1.55v is max safe. 1.45v for CPU-NB voltage.

But like its already been stated, it depends on what motherboard you're using.

ooh 62, gotta remember that, and to Gen I see you got to 4ghz just by keepin the vcore at 1.5(also wanted to know, cpu-z rates it at 1.488, is that just an estimate and did you enter 1.500 in the bios and that's just what cpu-z displays it as?) and multiplier at 20.0, and bus speed at default, did you do any changes to the NB or anything like that because that's the part I don't know how to do

I upped the CPU-NB to 2600MHz at ~1.25V. Depending on what motherboard you have will determine what settings can be changed.
