And to add another quick post. As mentioned, I've put in four 1024MB strips of (what I thought were) DDR2 1066 Apogee RAM, but as this pic shows, my AU$365 GA-X38-DQ6 is only reading it as PC6400. Should I be going back to the store where I bought the RAM, or is there something wrong with how the board reports the RAM in it to the OS?
