General memory module installation guidelines
To ensure optimal performance of your system, observe the following general guidelines when configuring your system memory.
If your system's memory configurations fail to observe these guidelines, your system might not boot, stop responding during
memory configuration, or operate with reduced memory. This section provides information on the memory population rules and
about the non-uniform memory access (NUMA) for single or dual processor system.
The memory bus may operate at speeds of 3200 MT/s, 2933 MT/s, or 2666 MT/s depending on the following factors:
●
System profile selected (for example, Performance Optimized, or Custom [can be run at high speed or lower])
●
Maximum supported DIMM speed of the processors
●
Maximum supported speed of the DIMMs
NOTE:
MT/s indicates DIMM speed in MegaTransfers per second.
The 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 installing memory modules:
●
All DIMMs must be DDR4.
●
Mixing of memory module capacities in a system is not supported.
●
If memory modules with different speeds are installed, they operate at the speed of the slowest installed memory module(s).
●
Populate memory module sockets only if a processor is installed.
○
In Optimizer Mode, the DRAM controllers operate independently in the 64-bit mode and provide optimized memory
performance.
