Posted January 3, 201114 yr P67A-UD5 bios with new microcode enabling 5.5G+ Sandy Bridge OC: http://91.121.148.119/downloads/BIOS/p67aud5.f5x
January 25, 201114 yr I purchased the UD5 MB as well along with a 2600k chip. I can get my chip up to 5.4 GHZ in BIOS but can not boot into windows with anything more than 4.4 GHZ. Of course with such low clocks this thing is running no more than 45c rock solid under burn. I am wondering if I am missing something in the BIOS settings since I just stepped up from a QX6850 running 4.2 GHZ under custom water. (The 2600k is already doubling every bench from the QX) I am not even getting 4.5 at any voltage. I am running 4.4 at 1.3.v easily atm. I am running the 6a BIOS ATM and have just gotten all of the new revisions today. I will have to give them a try. Hopefully I did not just get a weak chip.
