Also, occasionally I need to do multiple hard resets to get it to post (with both 720 and 550) when unlocking when first turning on my machine, or changing BIOS settings - after it 'warms up' and I get past the "Overclocking Failed!" screen, it boots fine.

Any of you other mobo users out there have these problems? I'd like to know if it's mobo specific as I also can't seem to O/C very well on this platform.

It does seem that the ASUS board is having issues, a few ppl don't seem to be able to get the 550's unlocked with the M4A78-E , so guess the same issue with the 'T' version too.
