Edit: Solved Ordered the Sapphire 7970 Dual-X in late October 2012 and got it early November. This is the first dedicated graphic card I've bought/installed, and it seemed to work fine. One day I decided to try bios bank #2 which is supposed to be the lightly overclocked bios: 1000MHz Core Clock and 1450MHz Effective Memory Clock (bios bank #1 is 950MHz Core and 1425MHz Effective Memory). I opened bitcoin mining software to see how it would compare, but it appeared to not have any improvement over bios bank #1. A few minutes later I got a bluescreen. I switched back to bank #1 again and haven't seen a bluescreen in months. I'm not sure if maybe AMD Vision Engine Control Center software is limiting the 2nd bios bank, if I need to reflash the bios, or if this problem is something different. I'm looking at this page: http://www.techpowerup.com/vgabios/...re&model=HD 7970&interface=PCI-E&memSize=3072 It seems this is the bios I'm looking for: http://www.techpowerup.com/vgabios/117406/Sapphire.HD7970.3072.120207.html I'm familiar with using command prompt, but is there anything I should know about ATI Winflash before I proceed? I heard that I may need to set ATI Winflash to run as administrator. Also, not quite sure I understand the difference between ATIFlash and ATI Winflash. Any suggestions / advice is appreciated. Mine has a blue pcb and I have it connected using 8pin and 6pin.
