Technicians in Japan have transformed Intel 450MHz Pentium IIIs into 750MHz Pentium IIIs and have encouraged the system bus to go like the clappers at 165MHz. The site, Tomato Overclockers, describes a method of transforming what is now a singularly cheap chip into something that bests the up-and-coming Coppermines in performance terms. The site lists, in the English language, the results it has. But as a local technician pointed out to us yesterday evening, overclocking is only for those who wish to take the x.86 platform to its extreme limit. For example, running cold water through PCs running at the UK standard of 220-240 volts using alternating current is not a good idea. Please don't try it at home. Thanks to Japanese reader Battlax for showing us what can be done. ®
