Mode-Specific Guidelines - Dell External OEMR R210II Owner's Manual

• One or two DIMMs per channel can support up to 1333 MHz.
• If memory modules with different speeds are installed, they will operate at
the speed of the slowest installed memory module(s).

Mode-Specific Guidelines

Your system supports both single channel and dual channel modes. A
minimal single-channel configuration of one 1 GB memory module per
processor is also supported in this mode.
Table 3-1 shows sample memory configurations that follow the appropriate
memory guidelines stated in this section. The samples show identical
memory-module configurations and their physical and available memory
totals. The table does not show mixed or quad-rank memory-module
configurations, nor does it address the memory speed considerations of any
configuration.
