This is not your average overclock, that's for sure. The folks over at Madshrimps managed to get the chip running at 3650MHz, and a little beyond. The setup isn't practical for any kind of long term use, but it's cool to see how far you can push some of these newer chips.
"At -190°C you might be surprised how high you can overclock a
CPU, with a few liters of Liquid Nitrogen to spare we poured it over a
Pentium M 780 to see how high it would soar. Of course we don't want
to destroy our hardware so we'll show you how to prevent condensation
to save your hardware from failure"
