Just repaired a 1.6b that had a blown RAM bank 2. This is my first ever 1.6b I've worked on.
Usually with FRAO systems there's a good reason for a RAM to die and it's usually a thick layer of once damp dust messing with things. But this time the motherboard was fairly clean.
Since this is my first 1.6b I don't have a record of common faults like I do with the others. Do Hynix RAM chips commonly go bad?
