i bought from machines..they offer free upgrade that time, swapped 1 stick of 1gb ram to 2gb. its Kingston ram..

initially got issues.. machine would crash/hang.. boot that time do funny things..went back to Machines and the fella changed the ram slots, swapped 1x1gb (original Apple) with the 1x2gb (Kingston) placement.. then it works fine until now.

the machine is very fast for my usage..so i don't need 4GB ram.. i do admit i want it. but no use lah.. Mac already so fast..not like Windows..ram hungry.
