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 X11DPU-X supports up to 2TB of 3DS LRDIMM (3DS Load Reduced DIMM), LRDIMM
(Load Reduced DIMM), 3DSRDIMM (3DS Registered DIMM), RDIMM (Registered DIMM),
NV-DIMM (Non-Volatile DIMM) DDR4 (288-pin) ECC 2666/2400/2133 MHz memory modules
in 16 slots. The X11DPU-XLL supports up to 2TB of LRDIMM (Load Reduced DIMM), RDIMM
(Registered DIMM) DDR4 (288-pin) ECC 2666/2400/2133 MHz memory modules in 16 slots
(Note: NV-DIMM, 3DSLRDIMM and 3DSRDIMM are supported when requested by OEM
only). 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.
