I have recently purchased a new Mainboard and Processor. It will run 100 Mhz FSB or 133 Mhz. It is a DFI AK75-EC Mainboard, with a AMD Athlon XP 1800+. I bought Kingston PC 133/256 mb Ram. I set up and configured the system on 100Mhz FSB, then afterdebating for awhile I decided to try to reach the full potential of this new Processor.
So I opened the jumper to 133Mhz FSB the machine will go through Post and I can get into Bios and see that it is running at 133Mhz and the processor is recognized at 1533 just like it should but it will not boot to Windows. I am wondering if maybe my Ram is out of Freq. Can somebody give me some suggestions? Please?

I am surprissed that the XP runs okay with a 100 MHz FSB. I thought they were designed for the 266 MHz FSB with DDR ram.
You might want to look through the BIOS settings, and verify what the actual RAM clock is. If the RAM clock was set to 133 with a 100 FSB, increasing the FSB to 133 may be overclocking the ram by 33MHz.

I suggest that you spend some time at one or more of the overclocking web sites.

I have checked the Bios and flashed to the latest version. When I bridge the jumper to run 100Mhz FSB I check the Bios and that is what it shows and the machine boots fine, but when I open the jumper to run 133 Mhz I check the Bios it shows 133 Mhz and 1533 for the processor. I enabled SPD and the machine still will not boot what are the chances of the Ram being out of Freq?
