Haswell-E is much more of a juggle than some previous chips in my experience. IMC quality is not easy to determine without also having determined the quality of the ICs on other systems. Your sticks may not be able to do it, or like Kimir pointed out, your IMC may just be saying "NO", or you may have just not found the right combination of voltages that let you run 3200. If you can boot into Windows at all, before you even bother stability testing, you should see that all sticks have made it through training. In my case, I can get into Windows with really low SA and voltage, but it always drops a stick. Sometimes it seems like it gets worse with more DRAM voltage because that last stick that gets dropped, now gets included but is significantly worse off for stability, and will send the system crashing faster than when only the three good sticks made it past training.
