533 MHz microprocessor was different from all other K6-2 processors in the sense that it required a motherboard with 97 MHz front side bus. Because not all motherboards supported this bus speed an easy solution to this was to underclock the processor and run it at 500 MHz (5 x 100 MHz) or 522 MHz (5.5 x 95 MHz), or overclock it to 550 MHz (5.5 x 100 MHz).
