9.Replace the left computer cover, reconnect the computer and peripherals to their power sources, and turn them on.
CAUTION: Make sure the memory module is completely seated in the system board connec- tor before applying power. Incomplete insertion can damage to the system board and memory module.
After the system completes the
NOTE: If the memory total is incorrect, turn off and disconnect the computer and peripherals from their power sources, remove the computer cover and memory module, and check all the installed SIMMs to make sure they are seated properly in their sock- ets. Then repeat steps 7 through 9.
The system detects that the new memory does not match the system configuration information, which is stored in nonvolatile
Press <F1> to enter System Setup.
10.Press <F1> to enter the system setup program, and check the Extended Memory category in the Main menu of the system setup screens.
See Chapter 4, “Using the System Setup Program,” in the system User’s Guide for more information.
The system should have already changed the value in the Extended Memory category to reflect the newly installed memory. Verify the new total.
NOTE: The value of Extended Memory is given in kilobytes. To convert kilobytes to megabytes, divide the kilobyte total by 1024.
If the total is incorrect, one or more of the SIMMs may not be installed properly. Repeat this procedure again, checking to make sure the SIMMs are firmly seated in their sockets.
11.Enter the system configuration utility. Then save the configuration and exit the utility.
Running the system configuration utility and saving the configuration is required for the system to recog- nize the newly installed SIMMs. See Chapter 5, “Using the System Configuration Utility,” in the User’s Guide for instructions on running the utility and saving the configuration.
12.Run the RAM Test Group in the system diagnostics.
See Chapter 5, “Running the System Diagnostics,” for information.
Installing SIMMs
The memory module has 16 SIMM sockets arranged in two banks. Install SIMMs starting with the bottom socket, J1, and work toward J16. All SIMMs in one bank must be the same size and speed, but SIMMs in bank 1 may differ in size from those in bank 2. If a SIMM is already installed in the socket you need, you must remove it. Follow the instructions in the next subsection, “Removing SIMMs,” if appropriate.
To install a SIMM, follow these steps:
1.Remove the memory module as described in steps 1 to 5 of “Performing a Memory Upgrade” earlier in this section and place the module with the system board connector pointed away from you.
2.Align the SIMM so that the notch is in the lower left corner.
The
3.Hold the SIMM at a
When properly inserted, the SIMM remains at an angle. If there is a gap between the clips and the SIMM, it is not installed properly and you must repeat step 3.
