Ordered 2GB extra RAM for my 24" 2.8 iMac from Crucial (Our business's Mactech pointed me to Crucial). Installed fine and worked initially last night. My wife called me on my way to work this morning telling me the iMac is now "beeping". Either the RAM is not pushed all the way in or it is a bad stick.
Also, I made two dumb mistakes when ordering. First, I ordered 2GB from Crucial, but did not realize I ordered two 1GB sticks. (I was trying to upgrade from 2 to 4). So I sent it back and got one 2GB stick. Finally received it in the mail and went to install it and didn't realize that the computer came with two 1GB sticks (there are only two slots). So, now I have to order another 2GB stick to make the upgrade complete (that's if I can get the new one to work).
Ugh.
