The system detects that the new memory does not match the system configuration information, which is stored in NVRAM. The monitor displays an error
message that ends with the following words:
Press <F1> to continue; <F2> to enter System Setup
8. Press <F2> to enter the System Setup program, and check the System Memory setting.
The system should have already changed the value in the System Memory setting to reflect the newly installed memory.
9. If the System Memory value is incorrect, one or more of the memory modules may not be installed properly. Repeat step1 through step8, ensuring
that the memory modules are firmly seated in their connectors.
10. Run the system memory test in the system diagnostics.
Installing Memory Modules
1. Turn off the system, including any attached peripherals, and disconnect the system from the electrical outlet.
2. Remove the cover (see "Removing the Cover" in "Troubleshooting Your System").
3. Lay the system on its right side.
4. Locate the memory module connectors in which you will install a memory module (see FigureA-3).
5. Press down and outward on the memory module connector ejectors, as shown in Figure6-4, to allow the memory module to be inserted into the
connector.
Figure 6-4. Removing and Installing a Memory Module
6. Align the notch in the memory module's edge connector with the alignment key in the socket, and insert the memory module in the connector (see
Figure6-4).
The memory module connector has an alignment key that allows the memory module to be installed in the connector in only one way.
7. Press down on the memory module with your thumbs while pulling up on the ejectors with your index fingers to lock the memory module into the
connector (see Figure6-4).
When the memory module is properly seated in the connector, the memory module connector ejectors should align with the ejectors on the other
connectors with memory modules installed.
8. Repeat step4 through step7 to install the remaining memory modules.
9. Perform step5 through step10 of "Performing a Memory Upgrade."
CAUTION: Before you perform this procedure, see "Safety First—For You and Your System" in "Troubleshooting Your System."
CAUTION: See "Protecting Against Electrostatic Discharge" in the safety instructions in your System Information Guide.
