Trying to add more RAM to Imac?

I have fairly old Imac. It was purchased in early 2007 and it is 20 inches. The model number of my imac is A1207. It currently has 1 GB of Ram but I'd like to upgrade it to 4 GB if possible. I know where the entry slots are on the Imac but I just wanted to make sure I do it correctly before embarking on it. Is there a particular brand or type of RAM I should be buying? Is there anything I should know about the process of adding and inserting the new RAM into the imac. Any thoughts or other information pertaining to this is appreciated.


Thanks!

They can help you with all your questions. They even have video on how to change memory.

Thank you. Since I already have 1 GB of Ram currently, should I just purchase 3 additional GBs of ram? Or, should I buy 4 GBs of ram and get rid of the current, original GB all together?

Your imac only has 2 ram slots so what you're proposing wont work. Nick has the answer for you. Also note the Apple stated max is 4 gig, however the Mactracker stated max is 6 gig.
