Dimm - NEC Express5800/B120a User Manual

9-14 Upgrading Your Server

DIMM

The DIMM (Dual Inline Memory Module) is inserted into the DIMM socket on the CPU blade. The
CPU blade includes eight DIMM sockets.
IMPORTANT:
The DIMM is easily affected by static electricity. Handle the DIMM
after making your body contact with a metallic frame section of the
server to discharge the static electricity on your body. Do not make
bare hands contact with terminals and components on the DIMM. In
addition, do not put the DIMM on a desk directly. See "Static
Precautions" for details of the static electricity.
Do not use any DIMM not approved by NEC. If an unapproved
third party's DIMM is installed in the server, not only the DIMM but
also the CPU blade may be defected. You will be charged by any
repair of a malfunction or defect caused by such a device within the
warranty period.
Number of DIMMs to be installed depends on its specification.
Registered DIMM: Can be installed one by one.
Unbuffered DIMM: Must be installed two in pair.
Installed DIMMs must be the same speed and specification. The
CPU blade does not operate correctly if Registered DIMM and
Unbuffered DIMM are mixedly installed.
When the server has only one CPU (a single CPU is installed in
CPU #1 slot), DIMM slots CPU1_DIMM1 to CPU1_DIMM4 (4
slots) are available.
Whole capacity of installed memory may not be detected due to
restriction of Windows.
