My machine works fine when I use Photoshop CS4 (GPU-accelerated) or when watching an video using MPC-HC and DXVA. However, when I have both open and running I frequently get lockups...the entire display just freezes for a second, and comes back about 10 seconds later. Event Viewer does not report a driver crash or reset. I'm thinking I need to boost up the DXVA clocks to match the 3D clocks, so what progam would I use to go about doing this?

If you wanted to make a change that you don't have to make every time, you'd need to do it in the BIOS. To do this, you can use Radeon BIOS Editor.

However, be sure you have access to another card in case something bad happens in the BIOS flash.
