For what its worth I got about 1.5 hrs Prime with these settings:

200x20
HT On
DRAM 1603Mhz
1.4V CPU
1.68V DRAM
1.35625V QPI
SpeedStep/Turbo Off
LLC Enabled
CPU/PCI Spread Spectrum Disabled
C-State Enabled/Auto
ACPI 2.0 Enabled

Rest ASUS Default

Gone retry tonight to see if it wasnt a fluke .. but I might be happy enough with this for everyday gaming use (which is all I care about in long run) - played Crysis & Assassins both over an hour with these settings no problems at all ..

Also primed for over an hour (stopped manually) @ 1.45V CPU .. but with crazy temps ..
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.
