Just to let you know, i purchased a P5Q3 one week ago, and the physical revision is 1.02G, came with bios version 0611, I bought it with Geil DDR3 1333 CL9, 2X 2Gb.
The board will NOT run this ram at anywhere close to full speed, 1066MHz is stable with rest on auto, can get slightly faster to be stable with higher NB and RAM voltages (1.8V Ram) running at rated RAM speeds. Will not run at 1333 no matter what settings/latency I try. It currently has 1103 BIOS version on it.
Just thought i would let you know for all the guys looking at RMA'ing....the newer boards are definitely not a sure thing.
Also, can anyone tell me whether the Corsair XMS3 2X2Gb 1333 CL 9 RAM uses the micron chips or the Samsung, and what my likelihood is of getting these to work (at a decent speed)? Only have one day left to return it/exchange.
