General Memory Module Installation 

Guidelines

 

NOTE: 

The information provided in this document supersedes the information provided 

in your Hardware Owner’s Manual.

To ensure optimal performance of your system, observe the following general 

guidelines when configuring your system memory.

 

NOTE: 

Memory configurations that fail to observe these guidelines can prevent your 

system from starting and producing any video output. 

• All populated memory risers must have identical configurations.
• The memory configuration for each processor must be identical for optimal 

performance.

• Memory modules of different sizes can be mixed (for example, 2 GB and 

4 GB). All populated channels need not have identical configurations. The 

mixed memory configurations must be of the size N+/-1.

• The memory speed depends on the processor bin.
• If quad-rank memory modules are mixed with single- or dual-rank modules, 

the quad-rank modules must be installed in the sockets with the white release 

levers.

• If memory modules with different speeds are installed, they operate at the 

speed of the slowest installed memory module(s). The memory speeds are also 

dependent on the processor bin.
