I find it most useful to google for the part numbers on the chips,
rather than part numbers written on the PCB or miscellaneous stickers.
The datasheet for the chip, combined with counting the RAM chips, and
noting if there are any non-RAM chips will tell you a lot about what
sort of RAM the stick is.
