WAIT just a min - we don;t know your build specs, let alone your mobo. We can't advise you a ram combo unless its QVL certified and if it has the right latencies and the frequency for your proc. Running on giher frequencies off the bat means an Overclock... that being said - Dominators are awesome when it comes to OC'ing reliability.
from your choice of rams - get the Corsair's or the G.skill Pi.
But please give us the mobo specs...
