sporadic Phenom core usage?

post #1 of 6
Thread Starter 
When ever I run super pi. (and I assume other single threaded applications) the core usage jumps from core to core on my 9850be. One second core0 will be 100% then it will switch, then switch again at random. Why is this and could it be hurting AMD super pi times?

Thats odd, I never had that issues with my 9600. I will be interested to see if others have this issue.

Dizzy, this sounds normal to me. If I'm not mistaken doesn't superpi usually use 99% cpu usage?

Good luck

it will use 99% of 1 core. Superpi is a single threaded application that only has the power to use one at a time. It just switches from one to another and it doenst look normal.

this happens on my quad too. uses 100% of 1 core for a few seconds then switches to another.

use the affinity changer in task manager to select it to cod4
