Memory Support
The motherboard supports up to 3TB of 3DS Load Reduced DIMM (3DS LRDIMM), 3DS
Registered DIMM (3DS RDIMM), Non-Volatile DIMM (NVDIMM) DDR4 (288-pin) ECC of up
to 2666 MHz memory modules in 24 slots. 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. 4. Unbalanced memory
configuration is not recommended.
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.
