The P6T Deluxe supports memory voltage changes in increments of 0.02 V. Since this particular motherboard did not support 1.650 V precisely, we chose the 1.66 V setting, which is probably within the safety factor Intel calculated into its 1.65 V "maximum" voltage recommendation.
Of course, we needed a Core i7 processor, but not just any processor would do. While most reviewers are stuck with Core i7 920 engineering samples that only support DDR3-800 and DDR3-1066 ratios (3x and 4x base clock, times two), our retail sample supports data rates all the way up to 2,133 MHz (8x base clock, times two).
