Have you run this experiment yourself???
It sounds like a very bad idea to overclock a CPU by such an extreme factor
(50%). Kryotech can do this because of their highly sophisticated cooling
system, but any ordinary system should be hard to overclock by more than 1-2
"steps" (i.e. 200->233->266, 300->333->350 etc.).
Before you kill your CPU, make sure to take a look at http://tomshardware.com
about overclocking basics... :)
