Memory
Note : Check the Supermicro website for recommended memory modules.
Memory Support
The M11SDV-8C-LN4F supports up to 512GB of Registered ECC DDR4 wth speeds up to
2666MHz in four DIMMs 4-channel memory bus. Populating these 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
•
The blue slots must be populated first.
•
Always 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 odd-numbered modules. However, to achieve the best
memory performance, a balanced memory population is recommended.
