I'm a multicard noob, please be nice.
I just received a stock reference 6970. I have a 6990 which I've used for a while. Neither card are OC.
I've tried using both on Linux and Windows. With each card separately they work fine, no problems. Together, my they wont play nice!
Windows - I can get in to my user account. If I only boot up using one gpu I'm fine, and I can run guminer fine. If I then boot up the other gpu by swapping monitor leads I get BSOD. If I start with both gpus attached, I get BSOD immediately I start guiminer.
Linux (linuxcoin 0.2a ) - boots up, gets to the penguin and coin logo, but then I get a black screen, no X, no cli.
1 30gb ssd
bluetooth keyboard and mouse
ASUS m4a89tb mobo
sempron single core
Corsair TX 850 PSU
I'm guessing from my symptoms that my psu isn't up to it, but from my noobish calculations I thought 850 watt would have been fine. I've seen similar questions in other posts, and 850 watt seemed ok there too.
Any ideas? Anyone successfully running a 6990 and a 6970 on an 850 watt psu?
Thank in advance
