[slacky1230]

ive just upgraded to 2x1GB corsair RAM but in cpu-z its only showing 266MHz but it should be running at 533MHz. how do i change it so its running at the speed its ment for, also on the post screen its showing speed: 1600 but it should be 4300

I doubt you've upgraded to DDR2 1066 RAM have you? If not, it should be running at 266 so it looks correct.

so ive upgraded to 533 but i thought it should state 533 but then realised about the doubling thing
