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:
●
LRDIMMs, and RDIMMs must not be mixed.
●
x4 and x8 DRAM based DIMMs can be mixed. For more information, see the Mode-specific guidelines section.
●
A maximum of three single- or dual-rank RDIMMs can be populated in a channel.
●
If memory modules with different speeds are installed, they operate at the speed of the slowest installed memory module(s)
or slower depending on system DIMM configuration.
●
Populate DIMM sockets only if a processor is installed. For single-processor systems, sockets A1 to A8 are available. For
dual-processor systems, sockets A1 to A8 and sockets B1 to B4 are available.
