DIMM identification
IMPORTANT: This server does not support mixing RDIMMs and UDIMMs. Attempting to mix these
two types causes the server to halt during BIOS initialization.
The memory subsystem may be populated with either RDIMMs or UDIMMs, but mixing
the two types is not supported. To determine DIMM characteristics, use the label
attached to the DIMM and the following illustration and table.
