phenom ii x4 955 4ghz

post #1 of 6
Thread Starter 
I was able to overclock the 955 to 4ghz, but it crashed when I play battlefield 3 for more than 5 minutes.What can I do to get the 955 to be stable at 4ghz while playing games?

1.4 is pretty low voltage to get 4 Ghz. You might have to increase that a bit.

You know you don't need near 4 Ghz to play BF3, right?

You are probably unstable. And I highly recommend staying away from overclocking on that motherboard as you may have problems with the VRMs in the future. (See sig)

Oh yes, look at that, 4+1.

Increasing the voltage on that motherboard could cause the VRMs to burn. Might not, but it's a very real risk.

I'd tone down the Overclock (You should still be able to get 3.6 easy.) and avoid upping the voltage to get 4.0 stable.

Download stability tests, like p95 for 6hours, linx, or IBT and then test your overclock for a while under load to see if it is genuinely stable. My rule of thumb for P95, and there are alot of different takes on this idea and most of them are right, is run it for as long as you would normally game or use the system under load. If a normal gaming session is 4 hours, run P95 for 4.5 hours to check stability.


Without testing, using a controlled test method to determine stability, you will never really know if your stable and might get data corruption and shutdowns until you are stable. Check the OC'ing PHII link in my sig for a little help on oc methodology.
