With what CPU? While the mobo can support up to 2133/2200 DRAM you have to have a CPU that can run that freq, also for 16GB you'll be better off with a 2x8GB set of DRAM, less stress on the MC (memory controller) with only 2 sticks so can get slightly better performance. If you have a K model CPU, and are OCing at all - would go w/ the 2133/9 Ripjaws X on the P8Z68

With the 2600K I'd stick with what I suggested, I've been primarily using GSkill now for over 5 years, still get the occasional client that specifies Corsair or Mushkin, but most all have been moving to GSkill and most new ones want to go the same way....GSkill is and has been the innovation leader that Corsair and the others now follow, Corsair used to lead the pack, but what, Corsair finally came out with some large (32GB) higher freq sets like 2400 just a few months ago (and you pay a premium for many of them) whereas GSkill has had a few different 2400 32 GB sets out for over a year and a half now...Plus haven't really run into any set of GSkill that didn't have some OC headroom, at least a step up
