@Ghostleader
if i remember correctly (i'll have to check again), with my gskill 2x2GB 8800 PI and ocz 9200 flex ii, i can do all things that you mention you couldn't do, as of now, i think it's definitely possible that this is a problem with only certain ram kits.

I think you´re right. I remember your screenies with those.

I forgot to mention that I have tried some 2x2 OCZ Reaper PC8500 ver3 and I have the same problem with those.

My Dominator are on the ram QVL list for this board, strange, it seems like there is some of those UD3P board that´s more picky the others.

I can boot with dual channel strap 333 multi 2,40B with bus 434 ram 1042 but not with bus 435 ram 1044, no matter what I do.


Run ram 1066 or 1080 with bus 400 or 450 in dual channel , single channel

This is the same with all my ram 2x1 (7 set) or 2x2 (3 set).


Strange thing, I can do 1200 with my 2x2 HyperX PC9600 at bus 400, 450 and 500 but not 1066 or 1080 at bus 333, 400 or 450.


I have revision 03, stepping A3 on my P45 chip.

Maybe I should try to RMA the board and see if the new one is better.
