DIMMs
This section describes how to install and remove DIMMS. Before performing any of
the procedures in this section, read “Safety” on page v, “Handling static-sensitive
devices” on page 4, and the following DIMM considerations.
DIMM considerations:
• SAMSUNG periodically makes updates available to provide enhancements to the
standard features of your server. Currently, your SS3840 supports the Memory
Mirroring and Memory ProteXion features of the Active Memory technology. How-
ever in the future, SAMSUNG might also support the hot-swap feature of the Active
Memory technology. Be sure to check the SAMSUNG support Web site occasionally
to ensure that you have the most current levels of system software installed.
• Your server comes with a minimum of four 512 MB DIMMs installed in slots 1, 3, 5,
and 7 in the SMP Expansion Module. When installing additional DIMM modules,
you must install four DIMMS at a time and in the order described in this section,
using the instructions in the "Installing DIMMS" procedure on page 24 to maintain
performance. Contact your resaler for a list of memory modules for use with your
server.
• When installing or removing DIMMs, it must be done in banks of four and in the
following order:
— Bank 1 = DIMM connectors 1, 3, 5, 7
— Bank 2 = DIMM connectors 9, 11, 13, 15
— Bank 3 = DIMM connectors 2, 4, 6, 8
— Bank 4 = DIMM connectors 10, 12, 14, 16
• Each DIMM in an individual bank must be of the same size and clock speed to
ensure the server will operate properly.
