I got a Gigabyte EP35-DS3R/Q6600 2.4 ghz in March, which I'm very
happy with. Vista x64 rates a 5.9 on every measure, except a 5.6 on
memory.

Memory is G.Skill, the package is marked:

F2-8000CL5D-4GBPQ

DDR2-1000 PC2-8000

2048 x 2

CL5-5-5-15 2.0~2.1V

Any suggestions?

Thanks

That is the rating for your memory.

To understand what it is doing currently, try

http://www.cpuid.com/cpuz.php

The memory tab will show the current settings.

The numbers on the CPU tab, such as core speed,
multiplier and bus speed, are also interesting,
as they indicate whether you are currently
overclocking or not. If you post some of that
info, perhaps that will make it easier for someone
to suggest what to try next.
