  1. Everybody probaly knows memtest, the problem is, i want
    to find out in a simple way which chip is causing the fault.
    Memtest does not tell afaik.

    What's the problem?
    Do you intend to replace chips on a Simm ?
    Are your trying to repair a 8088-type PC ?

    There are memory test programs that will give you the address of the
    problem memory. Which chip this is will depend on how addressing is set
    up in the pc and how the address lines are routed on the memory module.
    There's a chance you could make an educated guess if you had all the
    BIOS settings and could trace out the address lines on the mobo, but I
    may be overlooking something.

    Bart Bervoets, klinkt nederlands :p

    Het is een helskarwei om op te zoeken welke chip nu eigenlijk kure
    vertoond. Om het geld en de moeite te besparen is het makkelijker o
    een nieuw geheugenbankje te kopen.

    Maar als je het toch alsnog wilt weten, meestal werkt de geheugenban
    oplopend. Dus als je het geheugenadres of nog makkelijker de locati
    (aantal mb) waar de bank gefaald heeft, dan tel je het aanta
    geheugenchips. Nu doe je de hoeveelheid geheugen, die deel je door he
    aantal chips. Dan weet je hoeveel MB een chip is, en dan moet je haas
    wel kunnen bekijken waat de fout zit

    Bart:

    Try each chip one at a time. For further troubleshooting, try each
    chip and get a known good one, then test that known good in each slot.
