For me, CAS 6 + CAS Write 8 was faster than CAS 7 + CAS Write 7 and a lot faster than CAS 6 + CAS Write 7.
CAS Write 6 didn't work at such frequency with multiple kits that I tried.
Also, with four sticks, even on LN2, you just can't run 1200MHz+ CL6 or CL7 on M5E.
32M time on that screenshot is slow as I ran it with CPU-Z windows open during an exhibition.
