Hi People,
I've been having RAM problems with my Asus Striker II formula since I got it.
Basically It wont run at 1066 even though its supposed to, the system is totally unstable, clock the ram back to 800 and its fine.

Specs:
Ram - Corsair Dominator PC2-8500 1066 Scan LN23639 @ Dual DDR2-800 5-5-5-15 CR2
CPU - Core 2 Quad Q6600 @ 3.0Ghz tried it at stock
Mobo - Striker II Formula NF780I - Scan don't stock anymore
PSU - 800W Coolermaster real power pro
GPU - 2 x GTX260 Tired with single 260 and 9600GT made no differance

Voltages
The Ram is currently at 2.2V and working fine at 800mhz went upto 2.5 but didn't seem to make much difference at 1066
HT1.2 is at 1.4V
NB - 1.5V
SB - 1.5V

I have also had 4 x 1Gb Corsair and OCZ reaper ram in the Mobo with worse results with 2 modules in it works at 800 but with 4 I could only get it to 667
Is there something really simple I'm missing I've tried more things from forums than I can list and I've flashed the bios soo many times its unreal, yet its still not stable at the proper speed.
I'm going back to gigabyte when I finally upgrade again.
