I assume you mean a Z68 Ex 3 Gen 3 board?
Ah yes, yet another victim of using the Ivy Bridge CPU compatibility UEFI (and drivers) on a Sandy Bridge board, with a Sandy Bridge CPU. Not odd at all, your result is typical, in general.
I really wish ASR would give more warnings about this, but I guess the reality that the transition to the IB compatibility UEFI version is really the end of updates for all SB systems, is not something they want to advertise.
You can try flashing back to an earlier UEFI, if that works, forum posts indicate that it doesn't. The only fix I am aware of is getting a new BIOS chip from ASR with an earlier, non-IB UEFI on it.
