I've got a somewhat older GPU lying around that I decided to set up for mining purposes, as where its located I pay an all-you-can-eat electricity plan. Its running Win7 x64, ati stream v2.2, and poclbm but I never see it use more than 1% utilization on the GPU and its only going at 990khash/s max.

The card is currently running default speeds, latest Catalyst drivers, and nothing but Aero using the GPU at the moment.

Any ideas why its not using the GPU more?

EDIT:
I found out that it was reading my CPU as device 0 and my GPU as device 1. The guide I followed told me to set the device to device 0.
