Pros: Never maxes out, OC's well, Doesn't decrease max OCP
Cons: Price compared to two 2x4GB kits
I purchased these as 2 2x4GB kits but they might as well be the same exact ones just sold in a bigger pack. They never get hot. I have them OC'ed to 1851MHz and the best thing yet weirdest was when I switched out my Corsair XMS3 3x2GB kit for these, my overclocking to 4.4GHz got so much easier then before. Even with all the RAM slots filled my overclocking never got harder. Usually when you fill all the RAM slots it gets harder to reach high OC's.
