hi everyone, i just recently upgraded my new 2.4 mbp's ram to 4gb leaving me two 1 gb to spare. I was thinking about selling the old ram.... is that a good idea? - i read around, but it seems a little strange keeping the ram around just in case i need to send my system back for repair... and even then, changing ram doesn't void applecare does it? anyhow, 2 questions. 1. what is a good selling price? (i am currently thinking 100 dollars canadian for 2 1gb sticks, is that under or over or just right?) 2. i got an inquiry... will the ram work with a macbook Core 2 Duo 1.86Ghz system? thank you much.
