Dell PowerEdge R710 User Manual

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.
