General Guidelines for Optimizing Memory Performance
•
The blue slots must be populated first.
•
Only populate DIMMA2 and DIMMD2 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 will support odd-numbered modules (one or three modules installed).
However, to achieve the best memory performance, a balanced memory population is
recommended.
