Notes on the Memory Mirroring Configuration
In memory mirroring configuration, the menus related to memory mirroring in the
BIOS SETUP are grayed out and cannot be selected in the following cases:
■ When you install additional DIMMs that disable the memory mirroring
configuration
■ When you remove DIMMs that take down the memory mirroring
In this case, execute [Load Setup Defaults] to cancel the memory mirroring
configuration.
Procedure
1. Note the BIOS SETUP settings.
2. Press F2 during POST to run BIOS SETUP utility.
3. Select [Exit] → [Load Setup Defaults].
4. When a message "Load default configuration now?" appears, select [Yes].

Note: Executing [Load Setup Defaults] restores the default
