Windows 7: Cannot boot with Crossfire

16 Nov 2010   #11

Windows 7 Ultimate SP1 x64

Yeah, both of the cards are in the blue slots (I waited 2 weeks for a long enough Crossfire bridge). I tried installing drivers from Startup Repair, but it didn't work. Also, the only working system utility (CPU-Z) on Mini XP said that the first 5870 had stock clocks of 850/1200, while the second one is at 13/3200 for some reason.

Edit: I also tried System Restore to 2 hours before installing the two cards, but it did nothing.

Somehow, taking out the second GPU, rebooting, and switching verbose boot to normal boot meant that I could boot normally. I put the second GPU back in, reconnected and rebooted, and it works now. Thanks for the help.

To Crossfire, or not to Crossfire
I've been thinking about buying a second Radeon HD 4890 for my PC. Since I already have an ATI, going SLI would be expensive as I'd have to buy 2 graphics cards instead of one plus what would I do with my Radeon? So if I'm going multi-GPU, Crossfire is where I'm going. However, is it really worth...
