Use your fingertips to carefully spread apart the securing clips on each end of the memory module connector until the module pops up.

Remove the module from the connector.

If you need to install memory modules in two connectors, install a memory module in the connector labeled “DIMM1” before you install a module in the connector labeled “DIMM2.” Insert memory modules at a 45-degree angle to avoid damaging the connector

Ground yourself and install the new memory module:

If the memory module is not installed properly, the computer may not boot properly. No error message indicates this failure.

Align the notch in the module edge connector with the tab in the connector slot.

Slide the module firmly into the slot at a 45-degree angle, and rotate the module down until it clicks into place. If you do not feel the click, remove the module and reinstall it, and then proceed to replace the memory module cover.
