RAM voltage - Different RAM voltage on same board?

[wspanic]

Voltage 2.0V for = OCZ Gold 4GB(2 x 2GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit


Voltage 2.1V for = CORSAIR XMS2 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit

These have different latency/timing and different voltage. XP x64 is what I am about to install. Chip sets and processor should be OK for XP x64. Will these two memory sets play OK with each other, in theory? Or does the voltage/latency differences screw this up? Thanks for any help on my newbie build.

your more powerful set will have to yield to your weaker set, you can only set one voltage for all of them and one set of timings for all of them.
