Quick CPU oc stability test on dual core.

dagwoood · 31 Jul 2006 at 20:27

With my old Opteron 144 I would run Super Pi as a quick test to see if the CPU overclock was stable enough to at least survive a 1MB run. I would then run the longer tests(Prime, Occt etc)to prove it was stable.

With my new CPU(as per sig)I'm getting error messages if I try to run 2 instances of Super Pi, so I wandered what do you use as a quick CPU stability test with a 2 core processor before running the longer tests?

Cheers, dagwoood.

2 copies of prime in there own dirs and setting affinity to each core

the two super pi's must also be in seperate directories, ie you can run the same exe twice.

S"n"M is a good test

Thanks for that The Asgard, but I was looking for a quick test and I normally run prime for at least 8 hours when checking for stability.

How do you set the affinity? I came across how to do it some time ago but it's slipped my mind how you do it

Edit: Google was my friend and it jogged my memory on how to set the affintiy

That's where I was going wrong then; I created short-cuts from the same directory.

Will S"n"M automatically run both cores or is that a case of a separate directory as well?

snm will do both automatically.

Thanks for clarifying that

I had a thought; as 3Dmark06 is optimized for dual core CPU's, then a run of that would provide a quick way of provisionally seeing if the CPU oc was stable wouldn't it?
