Supported Dimms - IBM power PS700 Problem Determination And Service Manual

Supported DIMMs

Each planar in the PS700 blade server contains eight very low profile (VLP) memory connectors for
registered dual inline memory modules (RDIMMs). The maximum size for a single DIMM is 8 GB. The
total memory capacity ranges for PS700 from a minimum of 4 GB to a maximum of 64 GB.
See Chapter 3, "Parts listing, Type 8406," on page 229 for memory modules that you can order from IBM.
Memory module rules:
v Install DIMM fillers in unused DIMM slots for proper cooling.
v Install DIMMs in pairs (1 and 3, 6 and 8, 2 and 4, 5 and 7)
v Both DIMMs in a pair must be the same size, speed, type, and technology. You can mix compatible
DIMMs from different manufacturers.
v Each DIMM within a processor-support group (1-4 and 5-8) must be the same size and speed.
v Install only supported DIMMs, as described on the ServerProven
servers/eserver/serverproven/compat/us/.
v Installing or removing DIMMs changes the configuration of the blade server. After you install or
remove a DIMM, the blade server is automatically re-configured, and the new configuration
information is stored.
v See "System-board connectors" on page 8 for DIMM connector locations.
