I'd strongly say most 1.65V modules with XMP will be accommodated well. 'MemOK' buttom will ease up the task even more. If you want to go with freq higher than 1600Mhz, then by all means go.
XMP (Extreme Memory Profile) is basically a non-JEDEC approved SPD table for your RAM that is programmed into the sticks. By setting XMP you can run the sticks at their RATED (>1600Mhz) speed and timings even if it requires more voltage to do so.
XMP is provided by Intel itself, and if the stick says it supports 'XMP' and the MoBo says so as well, and the stick is within the supported freq (OC), then it will be compatible.
"* Hyper DIMM support is subject to the physical characteristics of individual CPUs."
^The statement is interpreted wrongly in above posts. By that, manufacturer is referring to a relation between the BLCK of the CPU and the DIMM freq. The CPU base freq is directly related to BLCK, and some CPUs (with lower clock speeds) might not allow high bandwidth sticks (>2400Mhz) to have stated timings, they might loosen them. This happens mostly when one is trying to combine, say a Pentium (w/o OCing) with a 2800Mhz stick. But your CPU has 4.4Ghz freq with boost which's fine for the high bandwidth sticks.
