If you want the fix for saved profiles being wiped you need to use UEFI 1.61 and newer. If the saved profiles being wiped aren't a big issue for you though, UEFI 1.6A in all my testing by some distance has been the most stable and has the double POST bug fixed. I do wish Asrock would look at that, AFAIK the only thing fixed with UEFI 1.61 was the saved profiles bug but stability somehow decreased when the system gets OC'd. Bad omen.
