Memory; General Guidelines For Optimizing Memory Performance - Supermicro SuperWorkstation SYS-531A-IL User Manual

3.4 Memory

The X13SAE supports up to 128GB of DDR5 Unbuffered DIMM (UDIMM) ECC/non-ECC with
speeds of up to 4400MHz.
Note: Check the Supermicro website for recommended memory modules.
Important: Exercise extreme care when installing or removing DIMM modules to pre vent
any possible damage.

General Guidelines for Optimizing Memory Performance

•
When installing memory modules, the DIMM slots should be populated in the following
order: DIMMA2, DIMMB2, then DIMMA1, DIMMB1.
•
For optimal performance, use DDR5 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 supports odd-numbered modules (one or three modules installed).
However, to achieve the best memory performance, a balanced memory population is
recommended.
