System Memory
Your system supports DDR3 ECC unbuffered memory modules (UDIMMs). The DIMMs can be 1066 or 1333-MHz. Single and dual-rank DIMMs can be 1066 or 1333-MHz.
The system contains four memory sockets, each two-socket set is organized into two channels. The first socket of each channel is marked with white release levers.
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 or 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 within a memory channel (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 DIMM_A1 or DIMM_B1.
One or two DIMMs per channel can support up to 1333-Mhz.
If memory modules with different speeds are installed, they operate at the speed of the slowest installed memory module(s).
Mode-Specific Guidelines
Your system supports both single-channel and dual-channel mode. 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 the physical and available memory totals. The table does not show mixed memory-module configurations, nor do they address the memory speed considerations of any configuration.
