The Blue sticks F3-12800CL7D run with much tighter timings, and higher default voltages, if you plan on OC, then they are better!
7,8,7,24 is quite tight for the price at 1600mhz, I bet there is plenty of headroom in these..
Its like the corsair dominators 1600mhz 9,9,9,24 with the big heatsinks..
the corsair xms3 7,8,7,20 1600mhz outperform them, have small heatsinks and are cheaper!!
