power button, and reconnect the system to power.
3 Turn on the system and attached peripherals and, as the system boots, note the messages on the
screen.
If the amount of system memory detected during POST does not match the amount of memory
installed or you receive a general memory error message, proceed to step 4.
If an error messages appears indicating a fault with a specific memory module, go to step 11.
4 Turn off the system and attached peripherals, and disconnect the system from the electrical outlet.
5 Open the system. See "Opening and Closing the System" on page 46.
6 Ensure that the memory banks are populated correctly. See "General Memory Module Installation
Guidelines" on page 58.
If the memory modules are populated correctly, continue to the next step.
7 Reseat the memory modules in their sockets. See "Installing Memory Modules" on page 60.
8 Close the system. See "Opening and Closing the System" on page 46.
9 Reconnect the system to its electrical outlet, and turn on the system and attached peripherals.
10 Enter the System Setup program and check the system memory setting. See "Using the System Setup

If the amount of memory installed still does not match the system memory setting, then proceed to
the next step.
11 Turn off the system and attached peripherals, and disconnect the system from its electrical outlet.
12 Open the system. See "Opening and Closing the System" on page 46.
NOTE:
Several configurations for memory modules exist; see ""General Memory Module Installation Guidelines" on
page 58.
13 If a diagnostic test or error message indicates a specific memory module as faulty, swap or replace the
module. Otherwise, swap the memory module in socket 1 with a module of the same type and capacity
that is known to be good. See "Installing Memory Modules" on page 60.
14 Close the system. See "Opening and Closing the System" on page 46.
