i have a black edition CPU, (Phenom 965) i changed the multiplier too make it 3.8GHZ and the NB to make it 2400MHZ, i've ran it in Prime95 for 1 hour and temps were around 52 average and max was 57, but how do i know its completely stable? i dont want to go into a game and my CPU to mess up..

Sorry for the stupid question, newbie to this :)

If its stable it should say passed test 1,2,3...etc. If it fails then it should say hardware failure detected, please consult stress.txt file. Essentially, your computer sounds stable enough. If I were you you should run prime 95 for the entire night to ensure stability of the CPU. Also when you are gaming don't expect your temperatures to be the same as prime95, it basically stresses your cpu out to the max which a game can't do.

Run the test for 12-24 hours. If none of the threads throw up an error and stop, then you have a stable processor.

i ran it last night for 9 hours 12 mins, i checked the results everything was successful but at the start of the test i had an error that said, rounding was 0.5 expected less than 0.4.

If you were running the blend test then its probably an issue with your RAM. Run all three tests and see the description of each test(one stresses cpu out to the max, one does half and half with cpu and ram and the other does little bit of the CPU and alot of the RAM). Run each one, I say start with the one that tests the ram a lot and see if you can replicate the same error.

Also, the 9hour test i did was the blend test i upped the vcore to 1.4 too see if it fixed the issue.

Oh yes, did you overclock your ram as well? It is crucial to do so with a CPU overclock.

i didn't touch the ram just my Multiplier and my NB frequency to 2.4

May I recommend you remove one module of ram and re-do the test? It is probably a defective ram module. One of them is defective so do the test twice while taking one or the other out.

so i tried them both took one out tested then swiched them around, and i had no errors with only 1 slot of ram in..

Hmm may be a compatibility issue? Are both ram sticks that same brand?
