Because I need more I/O ports then Workstation mobo can offer + I already have Nocua NH-D15 with only square-ILM 2011-3 mounts, so I don't plan buying another CPU fan Why Fatal1ty over Taichi? One reason: Fatality has already better built-in WiFi network, which is a MUST. So now to my question... Which server types of RAM does this motherboard support?

First, the types of memory that can be used with this board, or any X99 board, depends upon the processor type/model being used with the board.

The two types of processors that can be used in X99 boards are the consumer/PC Haswell-E and Broadwell-E HEDT models, and the equivalent generation server/enterprise Xeon processors.

The consumer HEDT processor models only support standard PC DDR4 memory.

The server Xeon processors support the registered or unregistered, and ECC types of memory. wardog's link explains the registered or unregistered aspect.

That is a limitation caused by Intel's specification differences between the two type of processors.

The specification page for the Fatal1ty X99 Professional Gaming i7 includes this:

Supports DDR4 ECC, un-buffered memory/RDIMM with Intel^® Xeon^® processors E5 series in the LGA 2011-3 Socket

That is key between support for the basically two types of memory.
