After speaking to Overclockers, I bought the P5K3, because they said it also supported DD2 (and indeed on the website it indicates support for DD2+DDR3) - but having now read around the internet a little, it seems to me that the board only supports DDR3?
Can anyone confirm this? I have paid for Saturday delivery, so will be a bit miffed if it turns up and the DDR2 RAM and that board won't play ball together!
Also bought the Xeon 3220 - wanted the 3210 but couldn't find one anywhere..
