Alu Mac memory

[Wayne s]

Looking to upgrade my memory and found a good price on Crucial.


I am a bit unsure if it is the right memory module for my system, even though it says it is. (2.4ghz 20 inch intel core duo) .http://www.crucial.com/uk/store/listparts.aspx?model=iMac 2.4GHz Intel Core 2 Duo (20-inch)

Could some one confirm that this is OK to use.

Also, can I put 2gig in with the 1gig that came with the Mac.

Thanks.

Wayne.
