Hello,
I have an Alienware M17xr2 laptop running win7, it seems my 2nd card does not want to play with GUIMiner. The first card works great and gets a nice mhash, but my 2nd card is getting about half the speed and shows very low clocks. Along with it being disabled in The Catalyst Control Center.
If i go CF (which dosnt help mining) then the card shows up as "Linked" and with normal clocks. But still when i run GUIMiner the 2nd card only runs at half speed.
Any tips? Id love to flash my 5870m's BIOS but theres nothing new for years now. All i have are new drivers to work with.
