I then can't boot up unless I unplug the PSU and reset the CMOS.
I think the UDP4 AM3 needs a Bios.. Ive been searching for results on that Mobo with X550 and im not finding much.

What settings does it take to run DDR3 1600mhz on this board? I can't even get it prime-stable @ 1600mhz CAS=11 (!!!) with anything between 1.6 and 1.95 volts. My RAM is new, rated at 1600mhz 7-7-6-18. The best I've been able to get prime stable is 1333mhz 7-7-7-24 (any timings lower that also fail). Could it be the board, or do I need to give mushkin a disappointed phone call? (if you don't want to clutter the thread, PMs work fine too).

Unfortunately, I don't have any other DDR3 sticks or DDR3 motherboards to test each component with.

On the bright side, this board will get me 3.7ghz and 2400 NB no problem on an 955 on air, so I can probably confirm what chew said, that the NB VID is being applied correctly, despite what software claims. (Not to worry, all the playing around I did with the memory was with everything else at stock clocks).
Im stumped ,, this ones for CHEW lol..

The UDP4 DDR3 version looks to have a wierd Bug with ram or something else....
