Main memory
5.1 Memory modules
The 12 slots (6 for each CPU) for main memory are designed for RDIMM
(registered DIMM, capacities: 2, 4, 8 and 16 GB) as well as for UDIMM
(unbuffered DIMM, capacity 2 GB) memory modules. The maximum main
memory is for installing UDIMM memory modules 24 GB (12x 2 GB), for
installing RDIMM memory modules 192 GB (12x 16 GB). Mixing both types of
memory modules is not supported and leads to an error message.
When using Westmere-EP processors LV-DIMMs (low voltage DIMMs) can be
used.
There are three modes of operation for the main memory:
– Independent Channel Mode / Performance Mode (recommended)
– Mirrored Channel Mode
– Spare Channel Mode
Depending on the mode of operation there are different population
requirements.

The types of memory modules and the modes of operation are described
in the Technical Manual or in the configurator of the server.

Notes on equipping
– Equipping always starts at DIMM slot 1A.
– The minimum memory configuration is 1 DIMM per system board in
Independent Channel Mode.
– Memory modules with different clock rates may be mixed. The system
automatically adjusts itself to the lowest clock rate.
– Single and dual and quad rank memory modules may be mixed.
– Install the memory module with the highest number of ranks into the slot with
the lowest number (e.g. modul typ 4GB 2Rx4 into slot DIMM1A and modul
typ 4GB 1Rx4 in slot DIMM2A).
