Default Windows Performance Index RAM scores

I have a Gigabyte GA-P35-DS4 board with the Q6600@stock and 4gb 800Mhz ram
(2x2gb) running 5-5-5-15 timings and vista is giving me 5.5 as the score.
Just something to compare it to.

Well, I had a play with FSB, I put it up to 1200 and my cpu multiplyer to
8x
and my RAM to 800. I got .1 better on the windows performance index
although I still think 5.5 is low. I think it's likely to be a bandwidth
issue although underclocking my cpu to 2.1 didnt change things either (not
even the processor score). Thanks for the help so far

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.
