Can I use an 800 bus P4 on my 533 bus motherboard, or Q2. Can I use a 400 bus Athlon on my 333 bus motherboard?
A. Intel processors have been multiplier locked for many years, AMD Athlons for over a year, so while the processor may work, it will run at a much slower speed. Some boards allow you to overclock your bus, but while you may be able to push your board to the higher bus speed, there aren’t any stability guarantees.
