1. Interesting - so there is something about the Taichi SMM causing this. Someone (ucode?) mentioned that there were some querks with the Taichi boards using multiple system registers to limit clocks, but I didn't get any details.I get the exact same results with the same board and cpu.
....
On the other hand I'm interested in if the asus z10pe d8 ws would work with one and also with two 2696s?
Maybe I'll change the taichi board to that so when I want to upgrade to 2 cpus the board will be ready.
What are the drawbacks using double-socket boards with only one cpu?
Would I achieve 3.3 or 3.4 ghz with one and with two cpus too?
2. "drawbacks" of the dual boards are:
a. need ECC memory
b. cannot changing timing of memory (as you can with normal DDR4 on a single board) - I run 2133@CAS 10 and see corresponding improvement in application level performance.
c. larger board limits and complicates case choices.
It can be run with 1 processor though. No issue there. I'll have an EP2C612-WS shortly to try out. I hope that performs as well as the Z10PE-D16-WS.
