Prime95

The only version optimised for dual core systems is version 24 apparently, version 23 and below will not stress your dual core as much as version 24. You don't need to install Prime twice, just copy the prime shortcut and place it in a new directory. Goes without saying that you need to set the affinity for dual core by unticking the affinity box and changing the core in one instance. Running two instances of Prime without affinity set only loads both cores to 50%.

SP2004 is also not dual core optimised. That is based on version 23 of Prime95.

Good point, strange, how much further does it go before Prime fails?

Its been 9 hours prime stable by upping the voltage 0.025v

Right,

I was running 1 instances on Core 0 and left Core 1 free to browse windows and such but it was mighty slow. I set the afinity in Prime to the correct core aswell. I have the AMD X2 driver installed and the reg thing from microsoft. I dont think sometihing is right here.

Any help?

After further investigating it would seem that windows is not setting the correct afinity for the cores. just did it manually and now it works. wont hve to do this all the timeto run applications properly will i?

No, windows does an adequate job of assigning each core a task. With Prime you are testing each core 'individually' for faults etc. Some people have had problems with some applications (Cod2/CSS spring to mind) where it needs to be run on one core only (affinity set). I havn't come across any problems with windows/applications/games etc yet (rubs wooden desk in hope). The only time you should need to set the affinity for best performance is when lets say you want to go gaming and do some encoding in the background. It would be better to set you games affinity to one core and background tasks to another imo. Windows will do this for you but tends to 'spread' the load over both cores.
