New E6600 setup, minor problems

[MatzeR]

GeIL 2GB (2x1GB) PC6400C4 800MHz Ultra Low Latency DDR2 Dual Channel Kit (GX22GB6400UDC)
Noctua NH-U12F
EVGA nForce 680 (Socket 775) PCI-Express DDR2 Motherboard
Intel Core 2 Duo E6600 "LGA775 Conroe" 2.40GHz (1066FSB)

Just a few problems, CPUz is reporting my chip " 266x6 = 1600mhz, Yet my bios shows *9 = 2400.

Im not used to CPU-z being wrong, is that normal?

Also the ram, is rated at being able to run at 4-4-4-12, from stock, yet attempting to set that stops my machine from posting, and resets itself into safe mode and waits to be set back to default. Anything im missing changing?

Just formatted so im working though it all, figured you lads could help me take a load off <3

Thanks in advance

Upped Volts to 2.1, and im in windows now, so looks like you hit the spot.

The Speedstep is disabled in the bios, And CPUZ is still on x6, Is there anything else that would effect it, or something i've missed in the bios.
