upgrading RAM for Win7 64

[Borealis7]

i'm going to switch to Win7 soon, and in the process buy 2x2GB DDR2 sticks.
i wanted to know if it'll be alright to use them alongside my current 2x1GB sticks for a total of 6GB?

i'm not concerned about o/cing issues that rise from using 4 sticks (if they exist...) because i o/c my CPU very mildly to 400MHz FSB, but i do bump Vmem to 1.9V from 1.8V.

is it going to work properly? and in dual channel?

thanks for your help.

1.8-1.9v is the JEDEC voltage standard for DDR2.

it should work properly, no way to tell for sure without testing it.

You may need to bump MCH up a touch, but that's about it.
