Memory Population Guidelines

• All DIMMs must be DDR4.

• Balance memory. Using unbalanced memory topology, such as populating two DIMMs in

one channel while populating one DIMM in another channel, reduces performance. It is

not recommended for Supermicro systems.

• In dual-CPU congurations, memory must be installed in the slots associated with the

installed CPUs. Also, an odd number of total DIMMs is not recommended.

• For MM, NM/FM ratio is between 1:4 and 1:16. The capacity not used for FM can be used

for AD. (NM = Near Memory; FM = Far Memory).

Guidelines Regarding Mixing DIMMs

• Populating slots with a pair of DIMM modules of the same type and capacity results in

interleaved memory, which improves memory performance.

• Use memory modules of the same type and speed, as mixing is not allowed.

• x4 and x8 DIMMs can be mixed in the same channel.

• Mixing of LRDIMMs and RDIMMs is not allowed in the same channel, across di󰀨erent

channels, and across di󰀨erent sockets.

• Mixing of non-3DS and 3DS LRDIMM is not allowed in the same channel, across di󰀨erent

channels, and across di󰀨erent sockets.

DIMM Construction

• RDIMM (non-3DS) Raw Cards: A/B (2Rx4), C (1Rx4), D (1Rx8), E (2Rx8)

• 3DS RDIMM Raw Cards: A/B (4Rx4)

• LRDIMM (non-3DS) Raw Cards: D/E (4Rx4)

• 3DS LRDIMM Raw Cards: A/B (8Rx4)

Memory Population Sequence

Blue slots versus black slots: Install the rst DIMM in the blue memory slot, which is the

rst of a memory channel.

The following memory population sequence table was created based on guidelines provided

by Intel to support Supermicro motherboards.
