The only way to speed up a 133 MHz processor is rising the system clock some more. Most motherboards offer 140, 142, 145, 150 and sometimes even 155 + 160 MHz bus speed. While most boards still run stable at 150 MHz, 155 MHz or more seem to be a problem for the chipset.

At this higher FSB speed, all components are being overclocked: CPU, chipset, controllers, graphics card and memory. If only one component fails, the system won't run stable any more. The following table will show you your options:

Only the slower Coppermine CPUs for 100 MHz FSB can be recommended for overclocking, as the faster versions come with too high multipliers. The 650 MHz model would have to do 866 MHz at 133 MHz FSB or 975 MHz in case of 150 MHz FSB, which both is usually too much. As always, only with some luck you may get a CPU which tolerates this speed.
