Dual Core Opteron help please

[warnea1984]

Hi there need a little help, I am running at stock everything at the moment but when I try and test both cores using SuperPi I can't run to instances of the program.

I set the affinity on both copies of SuperPI open to different cores, when I run the first instance it will run fine but the second instance fails with error

NOT CONVERGENT IN SQR05

Bore cores can complete SuperPI without errors, but only when the other core isn't running a nother instance of SuperPI.

Any ideas???

Are then any other programs I can use to test both cores under in case its a problem with SuperPI?

3D MArk 2006 runs through without problems.

I use SP2004 which is basically Prime.

Cheers Downloaded and got it working although it had an issue with the fact that I don't use virtual memory on my machine

Gonna leave it to test over night, how long should I let it run for ???

SP2004 is based on prime 23 which is notfully optimised for the newest dual cores. Prime95 ver 24.14 is the one you want to be using.

Prime95 version 24

You need to have to SEPERATE copies of SuperPI running from different folders. You will get that error when you run the same .exe twice.
