Ram upgrade from 4GB to 8GB
I own an iMac Intel 21.5" EMC 2428 with 4GB ram and would like to upgrade it to a total of 8GB.
Is there one 2GB ram card in each slot of my iMac that make up the 4GB, or just one 4GB card? I'd like to purchase a 4GB card from you, but want to make sure that will get me to a total of 8GB.
