On a P5Q series board, almost certainly 9x445 [5:6] DDR2-1068 will be better than 8x500 1:1.

You'll be able to lower voltages for the mobo, & will be able to run a much lower (tighter) tRD (aka Performance Level) & assuming the RAM can do that speed, much faster RAM too.

You'd want to check Everest to be sure, but i'd expect a properly tweaked 9x445 [5:6] DDR2-1068 to be a much better config than 8x500.

1:1 is not your friend on the P5Qs.
