3.4 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 H13SSH supports 24 DIMM slots with two DIMMs per channel (supports up to 6 TB DDR5-
4000 MT/s (1R)/3600 MT/s (2R)) or 12 DIMM slots with one DIMM per channel (supports
up to 3 TB DDR5-4800 MT/s). Refer to the table below for additional memory information.
Note: Check the Supermicro website for possible updates to memory support.

Note: Recommended 2DPC DIMM population for optimal performance
*AMD does not recommend installing 1, 2, 4, or 6 DIMMs per CPU socket, as it may impact
performance.
**Recommended for 16 - 64 Core CPUs.
***Preferred for 84 Core or higher CPUs, and recommended for all other CPUs.
