can i upgrade my ram at machines in Malaysia?
1) You're not telling us which MacBook Pro you have, as you did post this question in the MacBook Pro forum...
and
2) If you have an authorized Apple reseller in Malaysia, and if you have a user-upgradeable Mac when it comes to RAM, then I'd say yes.
Give us more information and we'll be able to tell you if your Mac is user-upgradeable or not.
