DIMM

The DIMM (Dual Inline Memory Module) is installed in a DIMM socket on the mother board
installed in the server.
The mother board contains 12 sockets in which DIMMs are installed. Two 1-GB DIMMs are
factory installed in DIMMs #11 and #21. (The factory-installed DIMMs may be replaced.)
DIMMs are installed on the sockets in the ascending order of DIMM group numbers in the unit of
two modules.

The server does not operate if DIMMs of different specifications are
installed in a single group.
