No, that can't be the problem. All Dell 7970m vbios have uefi support, including the 022.

From my experiences with the M15x I would say that you can always flash the vbios, but some versions will result in a black screen, requiring a blind flash to get it working again.

Of course, if that's not possible you can always just replace the vbios chip.

The Clevo and Dell card are different, hardware-wise. Clevo has cheaper cards, they left out some of the components on the reference board. MSI cards seem to be the same as the Clevos, but no CF connector.

Has anyone here tried the MSI 7970M cards in the R2? I don't mind not having the CF connector as I'm not planing to run CFX. My 6970M died few days ago and now I'm running on the old 4870 that came with my R2 until I get a replacement.
