General memory module installation guidelines

This system supports Flexible Memory Configuration, enabling the system to be configured and run in
any valid chipset architectural configuration. The following are the recommended guidelines for best
performance:
• RDIMMs and LRDIMMs must not be mixed.
• x4 and x8 DRAM based DIMMs can be mixed. For more information, see Mode-Specific Guidelines.
• Up to three dual- or single-rank RDIMMs can be populated per channel.
• Up to three LRDIMMs can be populated regardless of rank count.
• Populate DIMM sockets only if a processor is installed. For dual-processor systems, sockets A1 to A12
and B1 to B12 are available. For four-processor systems, sockets A1 to A12, B1 to B12, C1 to C12, and
D1 to D12 are available.
• Populate the sockets by highest rank count in the following order - first in sockets with white release
levers, then black, and then green. For example, to mix single-rank and dual-rank DIMMs, populate
