General Memory Module Installation Guidelines - PowerEdge M910

To ensure optimal performance of your system, observe the following general guidelines when configuring your system memory:

• Memory modules must be installed in pairs, beginning with the first two sockets in each set of memory modules. These sockets are marked by white retention levers.
  
• The memory configuration for each processor must be identical.
  
• Memory modules must be identical in size, speed, and technology in lock–step pair (same colored levers).
  
• If quad-rank memory modules are mixed with single- or dual-rank modules, the quad-rank modules must be installed in the sockets with the white release levers.
  
• If pairs of memory modules of different sizes are installed, the larger capacity memory modules must be installed in the lower numbered slots.
  
• Memory mirroring and memory sparing are supported only if 32 memory modules are installed.

Non-Optimal Memory Configurations

System performance can be affected if your memory configuration does not conform to the preceding installation guidelines. Your system may issue an error message during start-up stating that your memory configuration is non-optimal.

Memory Sparing Support - PowerEdge M910

Memory sparing (spare bank) is supported in systems that have one of the memory configurations shown in Table 3-2. The memory sparing feature must also be enabled in the Memory Information screen of the System Setup program. See "Memory Settings Screen." To use memory sparing, you must disable node interleaving.
