Hi, the overcloking is dangerous if you dont know the max. mhz accept your cpu, for example, for a 68060RC50 the max. is 66,666mhz but with this, some blizzards have problems, (but if you add one with a 66,000mhz work fine) witout any disipator and ventilator. With a 68060RC66 you can put max. 82mhz, (82,222mhz) work fine at 80mhz (i have this 80,000mhz) and on my system work without ventilator/disipator too and have 2 years running at 80mhz. With 603 240mhz only know replace the oscilator for one with 66mhz (66.000mhz) for the ppc, in this case, the ppc is overcloked to 260mhz (66x4) and work fine (i have friends with this ppc speed), but i dont know any friend with cyberstorm, but i think is equal (depending the original speed of you cpu)
