CPU usage goes up when I OC cards

618 21
When I OC the GX2s the CPU usage goes up from 4% to about 50% and its all on 1 core. What is causing this?

Any ideas what is causing this?

Just use Rivatuner to adjust..then close it down..all of your OC profiles will still be applied..and even fan speeds if 'locked'. Rivatuner uses ~2% CPU resources, with my rig folding 2x GPU's..

*Have you tried different drivers yet? I have not heard of that issue before...plenty of folks folding GX2's as well..
