The D3H supports all speed of DDR3 RAM currently available via dividers not just the ones you list.
If your using IVY CPU the sweet spot is 2133mhz in terms of performance.
Well with that CPU 1600mhz up is what you need but for me the best option is 2133 c9 best of all worlds.
have you looked on gigabytes qvl list for supported memory? Samsung green also works well now with latest beta bios's for gigabyte boards
