Removing a DRAM DIMM
To upgrade your computer to the maximum amount of memory, you may
want to replace the DRAM DIMM that comes preinstalled in your computer
with one of a higher capacity. To do this, you’ll need to remove the existing
DIMM following the instructions provided in this section, then install a
higher capacity DIMM following the instructions in “Installing a DRAM
DIMM,” next in this appendix.
To remove a DRAM DIMM, follow these instructions:
1 Push the ejector on the DRAM slot outward and down to open it.
Your socket may have one or two ejectors.
2 Press down on the ejector to release the DRAM DIMM from its slot as pictured in the
following illustration.
When the ejector releases, pull the DIMM straight up and out of the slot.
