Please help! I have an iMac late 2009 (21.5"). I want to upgrade the RAM from the 4GB it currently has to 16 GB. I bought 2 memory modules that are 8 GB each. When I took the older modules out and replaced them with the 2 8GB modules, the computer just beeps and won't go on.

 

There are 4 slots on the computer for memory modules. It has had only two slots filled thus far. If I want 16GB, is do I need to put four 4gb modules in?

 

Hope this makes sense.

 

I'd really appreciate any guidance!
