hi, your physical slot configuration seems correct.I have been through the posts multiple times but still can't figure out on the exact Lockstep settings to double (or significantly improve) the memory speed. I am running four Intel Xeon E7-8891 v3 procs. I have populated all blue slots in all 8 MemCards (Rev 1.01) with Samsung (32x8GB) [M393B1K70DH0-CK0] PC3-12800R modules. Could somebody be so kind and explain in detail on how to go about it?
lockstep (a.k.a 1:1 mode) will HALVE your memory speed, not double it. what you want is independent (a.k.a. 2:1) mode. the option to do this should be located under your chipset settings > memory configuration > VMSE lockstep mode
