Also if you look up QVL the board only supports 4 gigs if you have 2 sticks of 667mhz ddr2 ram at 2gb , made by only a few brands.IMO if you are considering this board for purchase....DONT....there are better boards out there , anyways hope this helps.
I already bought the board but only using 2 x 1GB DDR2 667. I know about the Kingston 2GB DDR6 667...It's just for someone who only surf the web...The BIOS update are for Wolfdale support (E7200 would be good). Myself have the Asus P5K but waiting for Asus to support the Q9450 C1! Of course waiting for the P5Q series to come out, which should be soon!
