I think that you've got a slightly better bandwidth because you use a different OS. I never had any problems using tREF 16383T with BIOS 0902. With BIOS 0803 it was sometimes stable and the next reboot it was unstable. If I use a different CPU GTL setting it doesn't allow me to use less CPU Voltage nor does changing FSB Termination Voltage. For 4.05GHz it's 1.20V+ or BSOD at 6+ hours Prime95 Blend.


Changing from Moderate to Lighter didn't only let me use less voltage for the same performance there is also a nice temperature improvement. The core temperature dropped with 3° Celsius under full load with LinX.

These are two tests that I did to see if the dye that I'm using in my loop isn't causing problems and gunk up my rad or blocks. Both tests where done with the same room temperature of 18° Celsius. The first one is with Ai Clock Twister Moderate and the second one with Ai clock Twister Lighter.
