Memory mirroring in independent memory mode
This topic describes using the memory mirroring feature in independent memory mode.
To enable the memory mirroring feature in independent memory mode through the Setup utility, select
System Settings
→
Memory
→
Memory Mode
. For more information, see “Using the Setup utility” on page
123. For more information and notes about installing DIMMs, see “Installing a memory module” on page 46
and “Independent memory mode” on page 53..
Consider the following information when using the memory mirroring feature in independent memory mode:
• Independent memory mode provides the most efficient performance.
• You can populate DIMMs in any order and there are no matching requirements. However, the DIMM
population sequence in the following table will provide the best performance when operating in the
supported memory modes.
• When you operate in this mode, the memory channel operates at twice the DDR3 data rate.
• Single-device data correction (SDDC) is supported for x4 SDRAM technology.
The following table lists the installation sequence for memory mirroring in independent mode:
