General Memory Module Installation Guidelines
To ensure optimal performance of your system, observe the following general
guidelines when configuring your system memory.
NOTE: Memory configurations that fail to observe these guidelines can prevent
your system from starting and producing any video output.
• Except for memory channels that are unused, all populated memory
channels must have identical configurations.
• Memory modules of different sizes can be mixed in sockets 1 to 6
(for example, 2 GB and 4 GB), but all populated channels must have
identical configurations.
• Memory modules are installed in the numeric order of the sockets
beginning with 1 to 6.
• 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 is also
supported in this mode.
Table 3-2 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.
