General Memory Module Installation Guidelines
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.
• Except for memory channels that are unused, all populated memory
channels must have identical configurations.
• Memory modules are installed in the numeric order of the sockets
beginning with 1 to 6.
Replacing Memory Modules
WARNING: The memory modules are hot to 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.
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.
1 Turn off the system, including any attached peripherals, and disconnect the
system from the electrical outlet.
2 Open the system. See "Opening the System" on page 52.
3 Remove the cooling shroud. See "Removing the Cooling Shroud" on page 62.
4 Locate the memory module sockets. See
Figure 5-1 .
5 Press down and out on the ejectors on each end of the socket until the memory
module pops out of the socket. See Figure 2-10.
Handle each memory module only on either card edge, making sure not to
