Memory Population Guidelines

When installing memory modules, always use DDR4 DIMM modules of the same size, type,
and speed. Mixed DIMM speeds can be installed. However, all DIMMs will run at the speed
of the slowest DIMM.
Depending on which CPU is installed, DIMMs should be installed in the following configurations
for optimized performance:
