Installing System Components 99
The memory speed of each channel depends on the memory configuration:
For single- or dual-rank memory modules:
One memory module per channel supports up to 1333 MHz.
Two memory modules per channel support up to 1333 MHz.
Three memory modules per channel support up to 800 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
There are two memory channels with each channel supporting a maximum of
two UDIMMs.
Table 3-1 show sample memory configurations that follow the appropriate
memory guidelines stated in this section. The samples show identical
memory-module configurations and the physical and available memory totals.
The tables do not show mixed or quad-rank memory-module configurations,
nor do they address the memory speed considerations of any configuration.
