However instead, I switched a while ago to a 2x8GB RAM kit from AMD (yeah I know LOL!) running 1866MHz at 1.50V and weird (working properly!) Command Rate of 3T, really good ram kit, very good performance, comparable (if not better) to my older Mushkin 2x4GB kit rated for 2000MHz CL9 1.65V
One thing I will tell you about RAM is that right now, you're going to get the most out of it by using a Command Rate of 1T. Every kit should be tuned for 1T and then all other clocks based on that. Running a 3T Command Rate will slow down process time quite a lot.

The best "out of the box" setting I found for my IVB rig (3770K@5.0, UP7, 2x680Ltg SLI) are the Trident X 2400 9-11-11.
Based on your serial numbers, you have Samsung IC's, can't say with certainty which though. I had no trouble getting the 10-12-12 kit to run 9-10-11 1T @ 1.625v, worth a shot. The 2400C9 I've benched upward of 2864 10-14-11-22 1T with just 1.695v.
Very flexible kits!
Samsung RAM is really good. However, you're better off waiting for DDR4 to come out right now. RAM prices have increased about 100% the last year. When I bought my 16GB kit, I spent $50 on it. Right now, a 16GB kit is $150+.
