Really struggling with this card. Have spent days trying to get to the bottom of it. Initially I got no screen until Windows, then I changed to a secondary display and that showed POST.
Now however I can intermittently boot into windows (whilst seeing POST). At other times everything starts up but I get no display and don't reach Windows.
I'm running on a new ASUS Sabertooth 990FX (rev.2) on latest firmware.
When I did get it to boot my Samsung diagnostic tool showed the SSD (840Pro) was not running in AHCI mode. So I restarted to get to the bios - blank screen.
I swapped out the card for my old GTX660 and boot with POST and Windows. Then the SSD shows as being in AHCI mode correctly.
So what is the 290x doing to give my mobo bios such a hard time? I'm unfamiliar with UEFI bioses so perhaps it's something to do with that?
Incidentally the easiest way to get to see POST/bios without sticking in the GTX is to pull a DIMM, presumably this is causing the bios to reassess the setup and thus revert back to something that does work with the 290x (albeit temporarily).
Any help would be much appreciated as my next test will be to hit it with a sledgehammer.
