2.4 Memory Support and Installation

Note: Check the Supermicro website for recommended memory modules.
Important: Exercise extreme care when installing or removing DIMM modules to 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.
•
Only populate DIMMA1 and DIMMB1 if the extra memory support is needed.
•
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 supports odd-numbered modules (one or three modules installed).
However, to achieve the best memory performance, a balanced memory population is
recommended.
