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.

The memory bus operates at a speed of 3200 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.

NOTE:

Fault Resilient Memory-Non Uniform Memory Access is supported.

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.

● x4 and x8 DRAM based memory modules can be mixed.

● 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. For dual-processor systems, sockets A1 to A16 and sockets

B1 to B16 are available.

● In Optimizer Mode, the DRAM controllers operate independently in the 64-bit mode and provide optimized memory

performance.

● The following table describes the memory population rules:
