Another update:
After the last post and about 2 reboots, the system started acting up again.
This time, I not only tried it after removing the MB battery for a day, as well as performing a full BIOS restore with the same results both times.
I have tried other brands of 1600, 1600+ (which is stated as supported by the MB) and 1333MHz RAM and am getting consistent results:
When 4 sticks are used, I get the same issue regardless of BIOS settings. When I restart (or sometimes just start) the system) the system exhibits the same issue (as noted in my 2nd post). If I use only two memory sockets, the system boots just fine.
In ALL cases, CPU-Z's memory tab is blank in the timing areas.
I have already pulled the board and eliminated all other components with the same results.
I did have another DX79SR, but with that board, it would not boot past an E7 code at all regardless of memory configuration.
I'm beginning to think that perhaps I have a memory controller issue with my i7-3970x.
I'm going to contact Intel support directly, but can anyone think of anything else?
