To my surprise, though, pushing the voltage to 1.65v which is the maximum we'd suggest on a RAM kit and moving the CMD rate to the more aggressive 1T, we ended up running the kit at 1943MHz DDR ...

This pushed our RAM up to 1720MHz DDR or a 120MHz DDR overclock, which is pretty impressive at the same 9-9-9-24-1T timings. You can see our CPU-Z validation here.
