Honestly, I never had so much trouble with RAM before on various platforms.
it is really helpful of you put your "rig in your sig" so we know what kit you are working with. http://www.overclock.net/t/1258253/how-to-put-your-rig-in-your-sig
If you have the gskill 2400 9-11-11-31 ram kit, that is a great kit! 2400, 2666 capable, but for most EVERYTHING we do, with the notable exception of extreme benching, tight timings at a lower frequency can be perfect. try 2133, 8-10-10-28-128-1T. leave vtt on auto (will run 1.05V at this ram speed w/ ivy-e) If that's is a gaming rig, I suggest using offset mode overclocking, and take advantage of this feature. You will not see or feel a difference between 2400@9 and 2133@8.
2400 (bclk 100) on the r4be with an ivy-e will need 1.2+/-0.05V on VTT and 1.15-1.18V VSA ... IME
