OCZ SLI ready Ram wont boot @ 1066MHz

I have this RAM:

http://gear.ocztechnology.com/prod [...] index.html

It IS rated at 1066MHz but whenever i set to this in BIOS the computer wont boot.

Is it supposed to able to boot @ this setting @ spec Volts (2.1v)? Or does it need to be @ 2.3v ???

Another thing is i have a phenom 9850 with a FSB of 207MHz ....so i am running RAM at 828MHz (2x414MHz) with 4-4-4-12timings @ the mo for 1:2ratio. But ive heard something like the phenom has an onboard mem controller so running @ a good ratio wont make a difference?? This sound right?

SO...

Would i be better off leaving at this setting of 828MHz or will i benefit more from upping it to 1066MHz ?? And will i need to budge up the Volts?

Rest of sytem spec is in my Sig.

Cheers, Dean.

tighter timings = better
4 4 4 12 is great! 828mhz on the ram is plenty fast for that chip.
I dont think you would notice any speed increases running 1066 on your current platform.
all it would do is loosen up your timings and increase your voltage to your ram..
