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

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.

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

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.

Hm, well that should really be getting 5.5 too if my mums 2GB DDR2 4200 gets
5.9. Maybe it's something to do with Quads

I'm actually wondering if your computers suffer a ding in performance
because the memory is not faster.
A quad processor has four CPUs trying to access the same memory and may be
reaching a bottleneck on bandwidth due to the memory being limited to 800
MHz. Basically, in your case, the WEI may be right in implying there is room
to grow. The quad processor should be capable of a particular bandwidth for
I/O to memory and the memory bus is reaching it's limit before the CPUs are
reaching their limit.

I have a two core system and it gets a WEI of 5.9 on memory (800 MHz). But,
in my case, that's the best it will ever do based on the CPUs bandwidth
availability.

It's definitely something to do with having a quad-core.

I have the same processor and RAM as you, and i get 5.2 on the WEI.
However, if I use msconfig (just type it into the search bar) to
disable one core, making it a triple-core processor, i get a 5.9.

I've been searching all over the internet and I haven't figured out
why yet, let me know if you find anything else out.
