    Default Fatal1ty z77 Professional can't detect GIGABYTE GV-R785OC-2GD Radeon HD 7850

    So after receiving an RMA motherboard from Asrock, I can't get my card to register on it's own. I have tried all of the BIOS versions, set to PCI-Express and all gens and all PCI-E slots.

    The only way that I could successfully get the card to be detected was to take my computer to my friends shop, take my card out, plug it into a different system. Did a full test, with all my equipment, put it all back into my system. First boot up the computer with a different graphics card. Let it run for 5 minutes, with that card working. Turn off my computer and remove power, quickly switch the cards, then I could get it to get detected, install all the software and let it run for a while during games with no issue. Once the computer is turned off and let powerless for 5 minutes my card would no longer get detected, so I redo the process again and get it to work.

    So I know the motherboard is good, I know the GPU is good. It's a compatibility issue with the z77 Asrock boards from what I'm reading from several Asrock customers in this forum and plenty of other forums.

    I don't want to have to deal with a second RMA and ship my board and GPU back for them to switch the cards and get mine to post and say it's my fault and charge me. This is a real problem that can be seen from several posts.

    So what other ways besides ditching this Motherboard or GPU can be done to get it to work even after a full power cycle?

    Same problem here with Z87 Pro 4 and Gigabyte GV-R927OC-4GD...

    Still nothing? I'm about to just give up on Asrock at this point.

    In many cases a newer bios is required for the video card to work.

    Ok something about this...
    I got this combination Asus 7850 CUII(secondary) and Intel HD4000(primary) (LucidMVP is on) everything is working fine with ultra fast boot option on.Just on random times when i open my pc it beeps 3 times and tells me that Asus doesnt have a compatible UEFI bios and stops there.I need to enter in bios turn on ultra fast boot again and then it works normal.
