Trying to upgrade the wifes P3 700 PC to allow efficient downloading and some level of multitasking so decided to go with a P4 2.4 GHz w/ 800 FSB as I built this box for my gamer son a few yrs back. Decided to try INTEL mobo (rather than usual ABIT/ASUS choice). BIG Mistake. Put a bunch of working parts on the board but couldn't get new 800 FSB P4 2.4 CPU to even POST. After a day of swapping parts (thinking maybe I shorted something) I started a serious web search for POST issues with INTEL mobos. Best I can tell is some INTEL boards claiming 800 FSB compatability, wont POST with 800 FSB CPU until BIOS is flashed. Of course I cant flash BIOS if system wont POST. Solution noted is try booting with 533 FSB CPU (which I dont have). Any other ideas?

Intel specs on your mobo says it supports 800,533 and 400 mhz Fsb, so it should be working. The bioid string is BF86510a.86a, it will support up to 4gb of ram. It is possible that you just got a bad board. The processor should have came with a cooling fan …
