Did just break the 4 Ghz barrier with my 955, but is it safe?

post #1 of 5
Thread Starter 
Hello.

I just did an OC, and I'm running my X4 955 on 4 GHz, but I'm sure on what vcore it can take. The specs are these:

FSB: 212
Multiplier: 19x
Vcore: 1.45 v

Haven't touched anything else.

I'm doing a render in LuxRender at the moment, to stress test it.

1.45 is fine

1.5 is comfortable for 24/7 ... 1.55 is probably the most I would throw at it, depending on cooling.

Ok. Here the breakdown on that you need to know for ocing any athlon II and phenom II cpu on air.
1) Max cpu voltage is 1.55v.
2) Keep temp under 55c.
3) NB frequency take it as high as you can take it and stable.
4) CPU/NB voltage max 1.45v. This the voltage for NB Frequency.
5) Keep HT around 2000.
