This maybe the limit of the CPU as that all I got from it on my Asus board, but that was only a quick test.

Will try my 5.4Ghz in the Asus 2600K chip in the UD4 later.
Thanks m8, much appreciated.
Brought mine in today, shop owner called me this afternoon he already got a new one.
I'm picking it up tomorrow, let's hope this one works correctly.

Which bios came with yours now?
Did you flash yours directly to the most recent one?

chew* :

did you try using the Normal + DVID setting, instead of setting VCore manually?
