CPUz Reporting Memory At Wrong Speed

[.Jay.]

I've just put a new system together today with the following spec:

Q6600 @ 2.4GHz
Gigabyte P35 DS3P
Corsair Dominator 2x1GB PC2-8500 (1066MHz)

I've downloaded and run CPUz which reports the CPU running at 2.4GHz, however the memory is reported as running at 533MHz (as if a 1:2 divider is in use).

I've checked the BIOS and the multiplier setting is set to Auto and reports the memory speed correctly at 1066MHz.

Any idea what's causing CPUz to report the wrong speed? Have I missed an obvious setting?

Cheers,

Jay

The BIOS frequency is reporting 1066Mhz which is correct. Its CPUz that seems to suggest its not running correctly.

Ok thanks for the reply, I understand what you're saying about the double data rate.

However, if you look at the SPD tab why does it say Max Bandwidth PC2-6400 when the RAM is PC2-8500?
