Main memory

Equipping rules

Performance Channel Mode

Requires identical modules on all channels of each bank for each CPU.

RDIMM memory modules are supported.

Spare Channel Mode

Requires identical modules on all channels of each bank for each CPU.

One-third of the capacity is used as a spare area – this reduces the usable memory for applications to two-thirds.

RDIMM memory modules are supported.

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.

The greater the capacity of the memory module, the further away from the CPU it must be equipped. This applies for each channel.

Single and dual ranked memory modules may be mixed. Quad ranked memory modules, on the other hand, must be used exclusively.

In mirror mode and in spare mode, memory modules of different capacities may be mixed on a bank by bank basis (2x2, see figure "Equipping the main memory in the different modes" on page 32).

The assignment of the DIMM slots to the memory banks and channels is imprinted on the system board next to the DIMM slots.
