Like the DS3 thread the mobo suggests 1.8v DDRII which i have in G.SKILL NQs but i also have a set of G.SKILL PKs which state their 1.9-2.1v will these still work with the DS4?
Yes. I'm not sure how high the voltage can be pushed on the board but you should be able to run them at that voltage. It should go up to 1.95v at least.
