Title: 1x 7970 and 2x 7950 in 1 rig.. Post by: Beans on May 11, 2013, 06:12:17 AM I've been running 2x 7950's in one rig and my 7970 in another rig because I have not been able to get them working together in one pc. I can't get the display on the pc to come up at all with three cards in it. I've had 3x5970's in the rig before and I know all my new cards work. Is there some driver issue on the new cards that prevents it? I had to upgrade to the new ati drivers to run my 7950's. Any advise on this would be great.

When i would put any load to one card it would go black if i went when giving its own power supply not sharing with other cards no black screen, and mining great.

I just realized that the issue is specific to the 7970. Even when it's the only card on the pc it won't boot. It works fine in my other pc though. I uninstalled all the video drivers, but still nothing on the video at all when its installed. Not even the bios show up.Title: Re: 1x 7970 and 2x 7950 in 1 rig..
