correct, skip to
step 9 .
8. If the memory total is incorrect, turn off and disconnect your computer and peripherals from their electrical outlets. Remove the computer
cover, rotate the power supply, and check the installed RIMMs to make sure that they are seated properly in their sockets. Then repeat steps
4, 5, 6, and 7 .
9. Reset the chassis intrusion detector by selecting System Security and changing Chassis Intrusion to Enabled or Enabled-Silent.
10. When the System Memory total is correct, press to exit System Setup.

Removing Modules
NOTICE: Before you upgrade the RIMMs, you must perform the steps under BIOS Recovery Utility .
To remove a module (RCM or RIMM), press the securing clips outward simultaneously until the module disengages and pops out slightly from the
socket (see Figure 3). If you remove an RCM or RIMM, you must install another RCM or RIMM in the empty socket before turning on the computer.

NOTE: The system supports no more than a total of 32 memory devices on all installed RIMMs. See Figure 1 for the location of a label
on the RIMM that identifies the number of memory devices it contains. You can also determine the number of memory devices
installed through the
System Memory option in System Setup.
