P4 2.80GHz Overclocked to 3.917GHz

vwbus writes "The guys at Muropaketti have taken a brand new Pentium 4 2.80GHz chip, bought a pint or so of liquid nitrogen and overclocked it to an astounding 3.917GHz. The Finns describe how they put together the system on their web page, and luckily there are a whole set of pictures which demonstrate exactly what they've done, so you don't need to understand Finnish to figure it out. The pictures show wisps of nitrogen evaporating from the jar sitting on top of the CPU, and they publish some SiSoft figures to demonstrate the kind of speeds they attained." The folks at Muropaketti have had a lot of practice with this cooling method.

Liquid Nitrogen for External Use Only

It is possible to hold some on your tongue and blow "smoke rings", but if you want to know what happens if you swallow it, you may end up in the running for a Darwin Award. This guy did it and failed to qualify (i.e. lived to tell the tale). It's in his own words, and he left out the goriest details, but it's still cringeworthy.

If you've seen this article before: yes, I know. Some people haven't. This is for them. Thanks.

Re:Over 4GHz?

Actually there were problems in going above 2.2GHz since that is negative number (using 32 bit signed). See here for example.
