General Guidelines For Optimizing Memory Performance - Supermicro SYS-521C-NR User Manual

General Guidelines for Optimizing Memory Performance

•
It is recommended to 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.
•
To achieve the best memory performance, a balanced memory population is recommended.
•
The motherboard will not support an odd number of modules except for a single DIMM
module necessary for board operation. To achieve the best memory performance, a bal-
anced (even number) memory population is recommended.
