Ok I know it's some sort of uefi bios issue. But how can I boot/post with this card on uefi motherboards? I've tested my card on an older AMD motherboard it it works (MSI 790fx-gd70).
My older card works on the motherboard an AMD 5850, boots no problem. On using the 970, I get pass the cpu/ram check, but it get blue Diode on the "DIAG_VGA" with the error code 62.
