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.
● Up to three LRDIMMs can be populated regardless of rank count.
● Populate four DIMMs per processor (one DIMM per channel) at a time to maximize performance.
● 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 DIMMs based on the following processor-heat sink configurations.
● Populate DIMM sockets only if a processor is installed. For single-processor systems, sockets A1 to A12 are available. For
dual-processor systems, sockets A1 to A12 and sockets B1 to B12 are available.
● Populate all sockets with white release tabs first, black, and then green.
● Populate the sockets by highest capacity DIMM in the following order - first in sockets with white release levers and then
black. For example, if you want to mix 16 GB and 8 GB DIMMs, populate 16 GB DIMMs in the sockets with white release tabs
and 8 GB DIMMs in the sockets with black release tabs.
● In a dual-processor configuration, the memory configuration for each processor must be identical. For example, if you
populate socket A1 for processor 1, then populate socket B1 for processor 2, and so on.
● Memory modules of different sizes can be mixed provided that other memory population rules are followed (for example, 4
GB and 8 GB memory modules can be mixed).
● Depending on mode-specific guidelines, populate four DIMMs per processor (one DIMM per channel) at a time to maximize
performance. For more information, see the Mode-specific guidelines section.

NOTE: If you are using a 1.8-inch hard drive/SSD system with four processors, ensure that you use
only 74 mm wide heat sinks for processors up to 105 W, 120 W, or 135 W.
