A current list of the memo ry modules re commended for this mainboard is available
on the Internet at: "

At least one memory mo dule must be installed. Memory m odules with different
memory capacities can be combined.
For D3441-S, D3445-S and D3445-K, only unbuffered DDR4 memory
modules without ECC may be used.
DDR4 memory modules must comply with the DDR4-1866 or DDR4 -2133 specification.
DDR4-2133 modules are downward compatible and are operated depending on the CPU.
If you use more than one memory m odule, the n make sure to distribute the
memory modules over both memory channels. By doing this you use the
performance advantages of the dual-channel mode.
Maximum system performance is achieved when identical memory modules
are used in Channel A and Channel B.
To simplify equipping, the slots are colour coded.
Depending on how the syste m is c on figured, the visible main m emory can be reduced.
