DIMM Replacement Recommendations

When installing and replacing DIMMs, follow the guidelines below:
 Install higher capacity (ranked) DIMMs first, following the population sequence for the memory mode
being used.
 Do not mix RDIMMs, LRDIMMs and 3DS DIMMs in the same node.
 Do not mix size and speed of DIMMs installed in DIMM connectors 1 and 3. The size and speed of the
DIMMs in connectors 1 and 3 must match each other. However, they do not have to be the same size
and speed as the DIMMs installed in connectors 2 and 4.
 Use compatible DIMMs from various manufacturers in the same pair.

The maximum operating speed of the node is determined by the slowest DIMM in the node.
