I just purchased this this from Newwegg.com. I also ordered 2 sticks of crucial DDR266 Mhz from them. While reading the Mobo book it says it supports DDR 333 and DDR 400. The reason I ordered the 266 was because newwegg had it listed in the item desription. Can I use this memory(DDR 266) or Do I need to get DDR 333 or DDR 400. I have the Intel 2.4 Ghz 800 FSB CPU.
