Memory Mirroring Support

The system supports memory mirroring if eight identical memory modules are installed in the system. Mirroring must be enabled in the System Setup program and can be used only if memory sparing is not enabled. (See "Using the System Setup Program" on page 31.) In a mirrored configuration, the total available system memory is one-half of the total installed memory.

Installing Memory Modules

CAUTION: Many repairs may only be done by a certified service technician. You should only perform troubleshooting and simple repairs as authorized in your product documentation, or as directed by the online or telephone service and support team. Damage due to servicing that is not authorized by Dell is not covered by your warranty. Read and follow the safety instructions that came with the product.

CAUTION: The memory modules are hot to the touch for some time after the system has been powered down. Allow time for the memory modules to cool before handling them. Handle the memory modules by the card edges and avoid touching the components on the memory module.

1Open the system. See "Opening and Closing the System" on page 46.

2Remove the memory cooling shroud. See "Removing the Memory Cooling Shroud" on page 52.

3Locate the memory module sockets. See Figure 6-2.

4Press the ejectors on the memory module socket down and out, as shown in Figure 3-13, to allow the memory module to be inserted into the socket.

5Handle each memory module only on either card edge, ensuring not to touch the middle of the memory module.
