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. 98 Installing System Components
