z87 oc formula bios 1.0 iirc. I think it is a cpu issue the mobo seems solid!!! I will flash it to the newest one and see if that changes.
To me the only little thing that bothers me is that vccio and vcssa can be changed by offset and not values.
From what i have seen in the 5 hours that the board rocks,if it wasn't a "rental" i would have ln2 the mem for sure,maybe i will get the little one for myself...
