Is it possible to upgrade the RAM in the MacBook Air A1237? If yes, please advise how? Thanks

To my knowledge you cannot upgrade the RAM on MacBook Airs. The RAM is integrated into the logic board and not replaceable.

Just to add information from answer of Matt Barnes , he is correct the ram is embedded or soldered on the logic board ….

What if i’M really cool in microsoldering(sad, but i’m not) Can I change the ram chips to get a bigger size of ram?
