I have a pair of 16 gb samsung bdie ram rated up to 3200 that I have managed to clock up to 3800 CL16-15RDC-14RP with gear down mode on (seems like gear down mode is pretty much required for dual rank ram) at 1.42V. IF is running stable at 1900.
I have two questions, firstly what is the maximum safe voltage for Samsung BDie ram. I read conflicting stuff with one post claiming 1.6 is fine which I doubt. A few posts seem to indicate 1.5 is fine for day to day and the overall consensus is that bdie ram can handle more voltage. I am pretty sure that I could tighten up the timings a bit more with voltage if its safe.
Second question and perhaps most important what would benefit the 3900x more, slower speed but tighter timing or faster speed (including if) but slower timing.
Edit: Just to clarify, I did try searching for this but all I see is comparisons between 3200 and 3600 which is a much larger frequency delta.
