    Hello,
    For those who might be interested, this is the clock generator on Acer Aspire One D260. It has:
    Intel Atom N450 1.66 GHz
    clock generator 9LVRS387AKLF.

    It has 72 pins, just like 9LPRS387BKLF

    It seems this is different from 9LPRS387BKLF, the paid version of setFSB doesn't support it. Also instructions from here http://forum.notebookreview.com/alienware-m11x/463095-m11x-clock-generator-ics9lprs387bklf-12.html don't work.

    It was TME locked but I managed to disable it by cutting pin 14.
    What I found by trial and error is that the M/N divider enabling is bit 2 in register 15h, instead of bit 0 like 9LPRS387BKLF, but beyond about 40MHz of overclock (by increasing 0Eh value) it freezes.

    So I guess I would need the datasheet for this... Too bad I can't find it on the net.
