it is fast enough, and u dont have to worry about boards, getting along with 4x1GB, and I get abit tired of D9s dieing......, but I misread your post u actually got the DIMMs, thats a different story, U might wana try the DFI X38 it seems prommising board as the P35 was a succes and the new X38 looks more or less the same only different chipset.
