Overall settings are XMP for my Corsair RAM. Any other voltages are left at AUTO.

RAM is running at 1688Mhz(20 passes of Memtest stable).

HT is enabled but with the P6T, Turbo and Speedstep are automatically disabled when you change the CPU multiplier to any value other than the default 20.

What boggles my mind is if I set my CPU multiplier at Auto(20), it's almost impossible to achieve any sort of stability at 4.0Ghz. At 211x19, no problems whatsoever in any stress-testing or benchmarks.

My CPU is under H20 which pretty much eliminates any thermal throttling but the 20x multiplier quirk is very annoying.
