Memory Support and Installation

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

Memory Support

The H11DSi / H11DSi-NT supports 2 TB of ECC DDR4 2666 MHz speed / 4TB of ECC DDR4
3200 MHz speed (Board reversion 2.x required), RDIMM/LRDIMM/3DS/NVDIMM memory in
16 slots. Refer to the table below for additional memory information.
