Third Graphics Card NOT WORKING 7970 + 7970 + 280x.
« on: December 14, 2013, 01:43:37 AM »
I have a mining rig that is running two 7970s. I purchased a 280x to give the rig more horsepower, but I am running into issues.

I have the two 7970s plugged into a 16x to 16x and a 1x to 16x. I am trying to plug the new 280x into my last 1x to 16x, but it is not showing up in device manager

I think my motherboard (M5a97 LE R2.9) is not seeing the third card. Interestingly, the 280x does show up in device manager when I swap it for the 7970 in the 16x to 16x.

How can I get all three to run at the same time?? Thank you much.


GPU - 7970 or 280x
