Sorry once again PC, I didnt see that jughead was using the P35C-DS3r. I have the P35 version.. So you were right, his does use DDR3, but mine does not, just DDR2 800/1066. Once again sorry about that I was just misunderstanding which board he was using. So do you still think I'm in a bit of a bind with the P35 DS3r board, with that DDR2 800.
