I have a Sapphire 5870 Eyefinity 6 and a XFX 5870 Eyefinity 6 which I am planning to use in crossfire next week. I have had the XFX 5870 for a while and have never had an issue with the card. I picked up the Sapphire yesterday and it booted right up as well, had temperatures all within spec, and even overclocked higher than the XFX ever did. Anyway, I put the card back to default clocks and put the computer into sleep mode. This morning when I woke up the PC to browse the internet there was no signal being fed to the monitor. I restarted the PC a few times to no avail and reset the bios settings (did not clear the CMOS). Still nothing. So then I took out the Sapphire and put the XFX back in and it booted up fine.
I'm not sure if the Sapphire card is actually faulty because it was working perfectly last night and during gaming I had no issues. For some reason there is an issue this morning with the card that I can't figure out. When I get home from work I will uninstall all drivers and clear the CMOS in the hopes that a signal gets fed to my monitor. Otherwise, what else could be the problem? It's literally the same exact reference card as the XFX with a different sticker on it so I don't think there should be any difference in build quality. I was playing Battlefield on it last night for crying out loud! Haha.
