
A set of 4 DIMMs (set of two “PAIR”s) is defined as QUARTET in this Guide, which is in the
same position viewed from two memory controllers on the same processor.
Example) In the following memory configuration diagram,
QUALTET #1 consists of PAIR #1 to which DIMM #1 belongs and the DIMM #1 is
connected to Ch.A of memory controller #1 and connected to Ch.1 of the memory
buffer #1 and of PAIR#2 to which DIMM #3 belongs and the DIMM #3 is connected
to Ch.C of memory controller #2 and connected to Ch.1 of memory buffer #3.
 In the configuration in which more than four processor memory modules are mounted, the
exact same type of DIMMs (Column/Row/Bank/Rank configuration) must be mounted to the
same QUARTE.

In the configuration in which more than four processor memory modules are mounted, DIMMs
must be added or reduced by the QUARTET unit.

Add in sets of 4 starting from QUALTET #1 in the order of lowest to highest number as a rule
when adding DIMMs.
