I just added a 7970 to my computer.  I have been trying different things, and I just cant get it going good.  This is a reference card.

Right now for testing, it is in the main slot, it is the only card installed, I have tried updating to GHZ bios.  That did increase stock clocks, but made no difference on the speed.  I have to manually set it to 925/1375 to get 550 again.  On my 7950 I can get 679khash overclocked, but this 7970 has to stay at 925/1375 to get 550khash and then it will not do any better than that.

I tried cgminer and reaper.  Suggestions? What other info can I provide that will help?
