QPI/VTT Voltage acts as the memory controller. In older systems, "Northbridge Voltage". The higher you go in memory frequency, the higher your QPI/VTT Voltage will be.
Trevorc, 1.50V is not bad. 1.60V+ is when things can get warm. As you raise these values, you will also want to check CPU temperature. As long as the CPU is not overheating, or rising above it's range, there is no real harm to hardware.
Regarding your question, you are correct in that the actual difference between DDR3-1600 and 2000 is not that large in real time. Only in benchmarking will you notice a difference in numbers; memory is only a small part for processing. Raising your CPU frequency would make an even greater impact than the 200MHz (400 effective) memory difference. So if you run them at DDR3-1600, overclock the CPU, and that will dramatically decrease your processing time versus DDR3-2000 with default CPU frequency. In fact, when you maximize the memory controller, it performs even slower, so although you may be reaching high numbers, the actual performance is decreasing.
Thank you
