Respuesta a "Can the RAM be increased to over 4GB?"Yes, it can be done. I own an i-mac intel 20" 2210, and I have managed to increase the RAM to 8 GB using two 4GB modules manufactured by Patriot (Patriot Signature Series) part# psd24g8002s. I am not sure if other modules by other manufacturers would work the same.
