What with Laptop memory getting cheap, I keep feeling that I should upgrade my laptop's RAM to 4gb. My early 2008 model MacBook Pro is still running off its default 2gb, and the little experiment I did (removing one of the sticks to cut it to 1gb) gave me the idea that the Mac likes more RAM, a lot.
But everywhere I hear that Apple memory is supplied as the EEC type, and cheap RAM is not the EEC type. Has anyone out there used proletariat-style RAM sticks in their fancy machines? Did it work OK?

Have you tried crucial?

They are usually pretty cheap, have a proper memory finder, and guarantee the memory will work.
Thats were I got the memory for my macbook pro from over a year ago.
