General Population Requirements
DIMM Mixing Rules
•
All DIMMs must be all DDR4 DIMMs.
•
X4 and X8 DIMMs can be mixed in the same channel.
•
Mixing of LRDIMMs and RDIMMs is not allowed in the same channel, across different channels, and across
different sockets.
•
Mixing of non-3DS and 3DS LRDIMM is not allowed in the same channel, across different channels, and across
different sockets.
