Memory voltages?

Ok here is a newb question that has to do with memory voltages.

I am purchasing a MSI 975X Platinum Socket T (LGA 775) Intel 975X ATX Intel Motherboard and looking at the specs on the MSI webpage is stats:

*Supports 4 unbuffered DIMM of 1.8 Volt DDR2 SDRAM
*Support Dual Channel DDR2 533/667/800MHz and up

Looking on newegg i can not find any DDR2 800 any lower then 1.9v. The only memory i can find is DDR2 667 @ 1.8v. So the question is, can i purchase this DDR2 800 @ 2.0v and just bump up the voltage of the mobo in the bios? or do i have to stick with DDR2 667?

Thanks for the info Mondoman.

From the info i gathered i will go ahead and purchase the DDR2 800 and if all is good ill play around with some memory OCing and raise the voltage closer to 2.0v.
