Upgrade of RAM do I need to reconfigure my PC I install Go, but does not show it.

My CQ56 has had an upgrade from 2 GB to 4 GB and does not show the upgrade, and I see no difference in speed. My question is I have to reconfigure the system.

This number CN is actually your serial number. Click on the link in my last post for the product number, it will show you where to find and give you an example for this.
