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 configuration fails to observe these guidelines, your system might not boot, stop responding during
memory configuration, or operate with reduced memory.
The memory bus may operate at speeds of 4800 MT/s, 4400 MT/s or 4000 MT/s depending on the following factors:
● System profile selected (for example, Performance, Performance Per Watt Optimized (OS), 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:
