The clock rate you are referring to is a multiplier of the bus speed. A
bus speed of 66 MHz that has a multiplier strap of 4 would give you a CPU
clock rate of 264 MHz. If you change the multiplier to 5.5 you will have a
CPU clock rate of 363 MHz on a 66 MHz bus. Sounds confusing, eh?
Overclocking doesn't always work. Mainly because the chip runs hotter. If
you have a 4.5 multiplier, try that because I seriously doubt you'll get
your 266 MHz chip to run at 363 MHz. Keep in mind that overclocking can
reduce the life of the chip. But, if you're like me, you'll be upgrading
your CPU in a year as the faster chips come down in price. So life
expectancy of the chip isn't a major concern to some people. FYI, I
overclocked my AMD K6-200 to 233 & it runs great (and cool).
