all ive read for years is make sure its prime95 stable...or ortho stable...but does it have to be? reason i asked...this 7750be @ 3.1 is prime95 stable for 10 minutes...but at 3.2, no matter the volts ive tried (maxed out at 1.40, didnt want to go higher due to stock hsf) it fails prime 95 within 5 minutes. Running 3dmark06 benchmarks and demo's on loop for 30 minutes yields no errors, no problems. So my question is...is this good enough as long as games and such dont crash?

I'd rather lose a few FPS in a game then to not be able to run it at all...

Thats right when my OC is unstable iv seen mishaps a many...GTA IV won't play for 5 mins without a crash when im unstable and the same has gone for my other games as well

Even after passing hours and hours of prime95 i could load up GTA IV or another intensive game and just crash...after tweaking my OC around i solved the problem easily and it was due to my OC of course

Sounds like your Kuma needs to be take out back and shot...replace it with a nice 720BE

Tis a good idea.

I had my Athlon II X4 up to 3.6 GHz, and it booted fine and even tested fine under small FFTs. As soon as I turned on Blend, it seized hard.

That told me that the CPU's memory controller could not handle the speed.

So definitely using prime or another stress tester is a valuable tool for exposing weaknesses in your setup.

In the end, being stable is the difference from raging over lost work, and well not raging over lost work.

10 minutes is far from stable. 3 hr prime 95 blend would deem 95% stable but most prefer a 8 hr run. 2-1/2hrs stresses NB pretty hard at 512K.

If it passes LinX it is Prime stable

. LinX is far better and gives faster results. I've had Prime 95 runs for hours and it crashed in Linx in half the time.
