Hi everyone!
I have a macbook air here, history unknown but I think someone tried to do something on it before. It looks like someone tried to reflow the memory modules but used a way too low temperature and no flux (The plastic around the modules are slightly molten but not enough to say they used more then 200C). Other then that nothing else seems to be touched
The system sometimes shows the 3 beeps and doesn't boot, sometimes it crashes while playing the chime sound (Which makes for some really loud and scary audio glitches!) or sometimes it just works for 2 to 10 minutes before the video glitches and the system freezes. The freezes do not appear to be temperature related and its just luck if it will keep on working. The system always crashes after a while and crashes faster if the memory is being loaded (memory testing etc.)
The voltage of the memory modules is at a stable 1.500V
I tried reflowing the modules with flux and waited until they floated on the solder before I moved on to the next chip. This only seemed to have made the issues worse and now it crashes way more often, I can usually only get up to 3 minutes or it shows 3 beeps at POST.
My bet is on a bad module somewhere. I currently don't have a lot of devices to work on so I'm alright with replacing the modules if that's what's needed.
So What modules should I buy? I prefer pre-balled or new ones as it would save me on time it takes to ball them.
EDIT: Here are a couple of pictures of when the device froze
