Memory Module Installation Considerations

The Sun Blade X6270 Server Module supports a variety of DIMM configurations that can include single-rank (SR) DIMMs, dual-rank (DR) DIMMs, or quad-rank (QR) DIMMs. When adding additional memory modules to the Sun Blade X6270 Server Module, you should consider the following:

■Physical layout of the DIMMs and CPUs.

For details, see “DIMM and CPU Physical Layout” on page 15.

■DIMM population rules.

For details, see “DIMM Population Rules” on page 16.
