I just installed a MIS 6340M motherboard. Every time I tried to boot up, all I could get was the self-test image for the monitor stating the monitor was O. K. and that I should check the PC or cabling. Well, after toying around with the board for some time I discovered that I could remove a jumper pin and my system would start as expected. This jumper pin when on, sets the FSB to 133 MHz and when off sets the FSB to 100 MHZ. My understanding is that the FSB is used to connect the CPU to main memory. My CPU is a Duron 1.0 GHz. And my memory is in 2 sticks of PC 133, 128 MB each.

I wonder why my system would not start, as my RAM is PC133? All I had connected to the MB at the time was the PSU, mouse, and keyboard. I also did NOT have the chipset drivers loaded at this point as I could not access my CD-ROM.

Any ideas and is there that much of a recognizable performance difference between 100 and 133?

Thanks!
