After a lot of digging and searching on the AMD website, here's what I found out directly from the horses mouth: =============================== An AMD Athlon™ processor that supports a 266MHz front-side bus (FSB) will work on a motherboard that only supports a 200MHz front-side bus, but the processor will operate at a lower frequency. A FSB that is set to operate at 200MHz is operating at a frequency lower than expected for an AMD Athlon processor that supports a 266MHz FSB. Consequently, a 266MHz FSB processor will operate at a lower frequency if the FSB is only running at 200MHz. For example, a 1000MHz AMD Athlon processor that supports a 266MHz FSB requires a 133MHz system clock (266MHz FSB) and a 7.5x multiplier. This results in a processor frequency of 1000MHz (system clock x multiplier = processor frequency). However, if the motherboard's FSB is set to 200MHz (100MHz system clock), the processor will only operate at 750MHz (100MHz clock x 7.5 multiplier = 750MHz CPU speed). =============================== So, to me that would indicate that as long as you can adjust the clock speed of your 200 FSB mobo accordingly, everything ought to be fine. Well, I'll know for sure in a few days. Hey Intel, AMD rulez!

Yes AMD rules You should be able to up your multiplier and get it to specs. Post back and let us know
