I think the motherboard is: 06/20/2008 - Bearlake - 6A79OM4BC - 00
But this does not tell me much - how do I use this to know which memory I can use?
64bit: my son will have to manage with the 32bit for a while - if I could just increase the memory a little
and (I think) the computer Medion MS 7502 (PC MT 7 MED MT 503)
But if I understand swifty_morgan's answer right (not so easy for a dummy like me), if I increase to 4GB then I will only waste energy (have higher electric cost) with little or no gain - or have I understood wrong?
