Chapter 3: Maintenance and Component Installation
DIMM Module Population
There is no specific order or sequence required when installing memory modules. However
do keep the following in mind:
•
Always use DDR4 DIMM modules 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 (1 or 3 modules installed). However,
to achieve the best memory performance, a balanced memory population is recommended.
