I took out one CPU from this board and the ram downclocked to 2133. I then turned off POR and set 2400mhz memory speed. Everything appears to be using 2400mhz. I am on linux so there is no proper way to check, for instance CPUZ, but all looks well.

The same menu allows speeds up to 3200. Can I buy 3200mhz memory and run it at correct timings? Can I overclock 2400 rated mem to 2666? I have a v4 broadwell xeon and I was under the assumption these won't overclock.

Before I go to the trouble of setting 2666 and possibly having to clear CMOS and/or recording all those bios settings, is this something that could work? I really need the memory bandwidth more than CPU speed.

So I tried the setting and it wouldn't go over 2400 as reported in bios. Will ram with faster timings work or just downclock?
