UPDATE:
Technical support wouldn't help me raise the speed of my existing 128 GB of RAM
Technical support also stated that the speed of a dual channel of 64 gb ram would be 4000 mhz, a single channel 64 gb ram would run at 5600 mhz
They mentioned nothing about a dual channel 96 gb ram stick, I assume that would run at 5200 mhz, either that or 4000 mhz???
