2.3 Memory Support and Population

Important: Exercise extreme care when installing or removing DIMM modules to pre-
vent any possible damage.
Note: When the motherboard is populated with 4 modules of 2S4R/4DR DDR4
LRDIMM, the memory speed will operate at 2133MHz.
When the motherboard is fully populated with 4 modules of single rank DDR4 RDIMM,
the memory speed will operate at 2133MHz.
When the motherboard is fully populated with 4 modules of 2R/2DR/2S2R/2S4R DDR4
RDIMM, the memory speed will operate at 1866MHz.
When the motherboard is fully populated with 4 modules of single rank DDR4 UDIMM,
the memory speed will operate at 2133MHz.
When the motherboard is fully populated with 4 modules of 2R/2DR DDR4 UDIMM,
the memory speed will operate at 1866MHz.

Memory Support

The M11SDV-4C/4CT/8C/8CT/8C+-LN4F motherboard supports up to 512GB of ECC/Non
ECC RDIMM, UDIMM, and LRDIMM DDR4 memory in four memory slots. Populating these
DIMM slots with memory modules of the same type and size will result in interleaved memory,
which will improve memory performance.
