Ram Bandwidth

[mpo26]

I don't really have an understanding of settings for motherboards etc. but I was hoping one of the experts on here could give me some pointers to what's wrong with my memory performance.

On running Sandra Lite, my memory bandwidth benchmark is only 5000 when systems less powerful overall are getting 9000 and much faster PCs well above this. All other benchmarks seem OK and I've experimented with the BIOS but still no luck.

My motherboard is Asus P5Q.

Here are my settings:

I thought the FSB might be the case, but in doing some research it seemed a lot of people with Q6600s had their FSB at 266 too. I didn't want to change anything which might cause problems.
