I installed 2 set Corsair CMT16GX3M4X2133C9 in in all 8 slots. But only 16gb is recognized in windows and in BIOS.
I use some program to check that.....only A1,A2,B1,B2 is running........
I try to remove and restall the ram many time..but the result is same....
Finally I have traced some problem on C2,D1,D2 ram slots.....
If I install the ram in A1,A2,B1,B2,C1......that is ok....20gb is recognized Windows and bios show.
but try to install ram in C2/D1/D2 ram slots.............only 16gb can be recognized in windows and in BIOS

I am sure C1, D2 are working normally...
Before I got 2 set Corsair CMT16GX3M4X2133C9. I install samsung 1333 4G ram *4 in A1,B1,C1,D1.....Evenything is fine.

should i rma my R4E?

Sorry for my poor english.....

sounds like your kits are not all matched. or its the limit of the cpu for that memory speed. talk to corsair and see about geting a matched set for all 8. in the mean time you should be able to run all memory at 1600 speeds.
