2.4 Memory Support and Installation

Notes: Check the Supermicro website for recommended memory modules. Exercise
extreme care when installing or removing DIMM modules to prevent any damage.

Memory Support

The motherboard supports up to 3 TB of 3DS LRDIMM/LRDIMM/3DS RDIMM/RDIMM/NV-
DIMM DDR4 ECC 2666/2400/2133 MHz in 24 DIMM slots. The black DIMM slots are reserved
for future NVDIMM support. Populating the DIMM slots in a 2DPC (two DIMMs per channel)
configuration with pairs of memory modules of the same type, speed and size will result in
interleaved memory, which improves performance.
Notes: 1. When installing DIMMs in a 2DPC memory configuration, first populate the
blue memory slot, which is the first slot of a channel, followed by the black slot. 2. Using
an unbalanced memory topology by installing two DIMMs in one channel while installing
one DIMM in another channel will result in reduced memory performance. 3. Memory
speed is dependent on the type of processors used in your system.
