2.3 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 X12SDV-10C/8C/4C-SPT4F motherboard supports up to 128GB of ECC or non-ECC
DDR4 RDIMM/UDIMM memory to 2667 MT/s (10C and 8C) and 2933 MT/s (4C). Populating
the DIMM slots with memory modules of the same type and size will result in interleaved
memory, which will improve memory performance.

General Guidelines for Optimizing Memory Performance
•
It is recommended to use DDR4 memory of the same type, size, and speed.
•
Mixed DIMM speeds can be installed. However, all DIMMs will run at the speed of the
slowest DIMM.
•
The motherboard will support an odd number of modules (one installed). However, to
achieve the best memory performance, a balanced memory population is recommended.
