I think I got to about 40 minutes before it failed at 200x20. But I've run over 14 hours at 211x19 with 1.36vcore.
HT is on
QPI-1.35v
Speedstep/Turbo off(systems defaults to OFF when using anything other than AUTO for a CPU multiplier)
DRAM voltage is 1.66v
The rest is the same as yours. There's something obvious that I might be missing but I'm happy with 4.0Ghz @1.36v for now.
