Are there any differences between the dominator

and the non-dominator sticks?

other than heatspreader?

Could also be different revisions, any info on Corsair's site?

The diffrence is the cooling. Dominator refures to there patented cooling fins that cool both the surface of the chips and the PCB. Otherwise the chips used are the same.
