Crazed Kiwis run Celeron at 1057MHz
Don't try this at home folks
Wacko New Zealand site OCTools has succeeded in running (briefly) a hapless 566MHz Celeron at almost 1.1Ghz.
All that was needed was 2 Gallons of Flourinert (cost: $1,000), copious quantities of dry ice and 30 litres of liquid nitrogen, large blocks of aluminium, tubing, clamps, thermometers and neoprene sheets, a couple of day's preparation and storing the mobo in the freezer overnight.
While the creativity has to be applauded, one cannot but help ask the question: "Why?"
A 1GHz Pentium III costs $669, while a 566 Celeron is just $90, add in the $1,000 for the Flourinert stuff and you're already well out of pocket, without even taking into account the price of the dry ice and liquid nitrogen and the sheer buggeration factor involved in putting it altogether (ignoring the risk of your hands dropping off) and the whole thing looks like the most pointless exercise since Leonard Cohen entered the World's Most Cheerful Man Competition.
But hey, that doesn't mean it's not fun - go check it out. ®
