See my reply to CMJ.
I think it's your motherboard.

Well, my timings were 4-3-3-10 1T on CPU-Z and the speed was 800mhz. My
RAM
is OCZ SLI 6400, all sticks are at the same. However, I OC'd the RAM to
850Mhz and changed the timings to 4-4-4-12 2T and Vista scored it the same
which seems a bit odd. I think even DDR1 RAM can score higher than 5.4 as
well. I think it's either Vista or my motherboard, unless I have a
bandwidth
issue because of the Q6600. Thanks for the suggestions,

It has been seen in some cases that the clock speed of the CPU and the
bus
speed of the memory may not be a good match. _Sometimes_ with
DDR2-6400,
it
is better to slow it down to 667MHz in the BIOS.

When overclocking, it is often better to make sure the RAM:FSB ration is
1:1, and hence you often choose to reduce the RAM speed, but in general
use,
I've never come across a situation where properly rated RAM is better
run at
a lower frequency.
