General memory module installation guidelines
Your 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 cannot be mixed.
•
x4 and x8 DRAM based DIMMs can be mixed. For more information, see Mode-Specific Guidelines.
•
Populate up to three dual- or single-rank RDIMMs per channel.
•
Up to three quad rank LRDIMMs 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, B1 to B12 and sockets C1 to C12,
D1 to D12 are available. Each processor requires a minimum of 2 DIMMs, which must be identical.
