Ram in dual channel, you want to find all 4 at the same speed but in size they only need to come in pairs.
i.e. a set of 2x2 & a set of 2x1 is ok so long as both sets are 1600.
If one set is slower than all 4 will downclock to that speed.
In any case I would Highly suggest getting the exact same kit as you have now to prevent any timing conflicts or downclocking.
Will definitely get the same kit to avoid issues. Seems I should just get the same 5770 graphics card as well to avoid issues. Thanks for the heads up Abstract.
Edit: What would be a good SSD to pick up for my rig?
