computer cover .

sockets in which you plan to install the upgrade modules.
NOTE: The system supports no more than a total of 64 memory devices

the RIMM that identifies the number of memory devices it contains. You

installed modules to ensure that they are seated properly in their
sockets. Then repeat step 5 through step 7 .
