You must note these guidelines when installing DIMMs:
• Memory is increased or decreased in two-DIMM increments only.
• The two DIMMs that make up a bank pair must be the same memory size; however,
each pair of DIMMs can differ in memory size.
• The first two DIMMs must be installed in DIMM slot 0 and DIMM slot 1.
Subsequent DIMMs can be installed into any bank pairs as long as the two DIMMs
are installed so that they provide local memory for the same bank pair. For example,
you can install DIMMs in slots 2 and 3 to provide local memory for banks 2 and 3.
Or you can install DIMMs in slots 4 and 5 to provide memory to banks 4 and 5, or
you can install DIMMs in slots 6 and 7 to provide memory for banks 6 and 7.
• The DIMMs used in the Origin 350 server system base compute module, the system
expansion compute module, and the MPX module are not compatible with the
DIMMs used in the Origin 200, SGI 2000 series, Onyx2, or Octane systems.
• The Origin 350 server system supports the following memory kits:
– 1-GB kit with integrated directory memory.
– 2-GB kit with integrated directory memory.
