Non-mirroring (independent mode)

This section contains information pertaining to the non-mirrored-channel mode of operation.

Note

When you install an optional microprocessor and memory expansion tray in the server, microprocessors 3 and 4 must be installed as a pair. The server does not support a configuration of three microprocessors.

The following table shows the DIMM population sequence for the non-mirrored channel mode of operation.

Table 1. DIMM population sequence for non-mirroring mode (independent mode)
