Vengeance Pro is much better!
I thought I would not go away with strips for they are original in CL9-9-9-24 for non 1600Mhz bah! all wrong the moment she rises to 2600MHz! in CL12-14-14-36 1.72V! So it has earned 1Ghz is really huge! (I think can reach 2800Mhz!
she overclock very well on Haswell platforms (not tried on ivy bridge and other ....)
they are really great!
ps: you save not far from 60 euros with manual OC: p
10/10!
