    Testing and replacing soldered RAM.

    Hello again everyone.

    I am curious if anyone has tried to replace soldered RAM before, such as the RAM on a Macbook Air.

    I have a 2009 Macbook Air logic board that is currently bricked because of bad RAM (i.e. constant stream of 3 beeps on boot). I've considered the brute force method of replacing all the RAM modules, but from what little reading I've done I understand that you're more and more likely to break the board after each heating cycle. So this leads me to my next question: Is there a way to interface with the logic board to determine which ram modules are bad?

    Has anyone had any experience replacing soldered RAM modules before?

    macbook air 3 beeps noise , many time are related to bad MCP solder joint !!!
    in my exprience on the latest 100 mac book air , none of them was ram !!!!

      I had a feeling it might not be necessarily RAM related. I have another MBA 2009 Board that works, but fails MemTest. This is could be a reflow job, then?
