ASRock 970 Extreme 4 issues on third PCI-e slot with AMD 7990

edited December 2013 in Hardware support

 having some issues with a 970 extreme 4 anyone know anything about its third PCI-e slot not reading the second gpu core on a 7990?

everything else looks to be working fine, I can mine on its first GPU but the second one is nowhere to be found. Could it be Windows 7?

I've thought of updating the BIOS but I'm not sure if ASRock have addressed the issue

any thoughts?

  • Sounds like a power problem.

    You will have to throw in some more details though, e.g. PSU, number of GPUs, how are they connected...
    Otherwise it's just looking into a crystal ball...

  • hi.. any luck?
    I have the same problem.. my third slot doesn't recognize any card..

    HI  the middle pcie x16 slot does not seem to work well on this mb with multiple gpu. All the other slots  work fine and running 4 cards is not an issue using the other slots
