Installing a Memory Module
Upgrade the memory in your PC with memory of the
same type and speed as the memory originally
installed in your PC.
CAUTION: When handling a memory
module, be careful not to touch any of the
contacts. Doing so may damage the
module.
1 Open both latches of the memory module socket:
•
If you are replacing a memory module, put the
new memory module in the same memory slot
from which the old memory was removed.
Or
•
If you are adding a memory module, install the
new module into the socket nearest the
preinstalled module, and install additional
modules in the next available sockets.
2 The memory module can be installed in only one
way. Match the notch on the module with the tab
on the memory socket. Push the module carefully
and firmly into the slot, ensuring that the latches on
both ends snap into place.
3 Set the chassis upright.
4 Complete the procedures to replace the side panel,
and close the PC. See “Opening and Closing the
PC“ on page 1.
NOTE:
If your computer shows a blank screen after
you replace or add a memory module, the memory is
installed incorrectly, or it is the wrong type of memory.
Remove and reinstall the memory module.
