Installation Manual
Helpful hints & troubleshooting tips
If your system does not boot, check the following:
1. If you receive an error message or hear a series of beeps, 
your system may not be recognizing the new memory. 
Remove and reinstall the modules to ensure they are 
securely seated in the sockets.
2. If your system won’t boot, check all of the connections 
inside your computer. It is easy to bump a cable and pull it 
out of its connector, disabling devices such as your hard 
drive or CD-ROM. If your system still won’t reboot, contact 
Crucial Technical Support.
3. When restarting your system, you may get a message 
prompting you to update the configuration settings. Refer 
to your owner’s manual for information. If you are still 
unsure, please call Crucial Technical Support for assistance.
4. If you get a memory mismatch message, follow the 
prompts to enter the Setup menu, and then select Save 
and Exit. (This is not an error—some systems must do this 
to update the system settings.)
If you encounter any of the following problems, please 
contact Crucial Technical Support:
1. Your module doesn’t seem to fit; do not force it into the 
socket.
2. Your system is recognizing only half of the new module’s 
memory.
