A current list of the memory modules recommended fo r this mainboard is available
on the Internet at: "
http://www.fujitsu.com/fts/product s".
At least one memory module must be installed. Memory modules with different
memory capacities can be combined.
Only unbuffered DDR4 memory modules without ECC may be used.
DDR4 memory modu les must comply with the DDR4-2133, DDR4 -2400
or DDR4-2666 specification.
DDR4-2133 modules are downward compatible and a re operated depending on the CPU.
If you use more than one memory module, then make sure to distribute the
memory modules over both memory cha nnels. 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 c olour code d.
Depending on how the system is configured, the visible main memory can be redu ced.
