Fellow Dell'ers,\n\nI have here a GX100 mini-desktop system that currently has a\nCeleron 400 CPU. I would like to replace this with a Pentium 3 at a\nhigher speed, but I'm uncertain which chips would be compatible with the\nsystem.\n\nThis particular model appears to have a 100MHz front-side bus. I've\nalready tried a P3-850 with no luck (wrong multiplier or wrong FSB\nclock, perhaps? It wouldn't even POST...)\n\nPlease advise. Thanks much.
