You've just been lucky. You should of course note any computation you did
in the last 6 months is quite possibly going to contain errors and if
you've done something like contributed to the DES cracking project you
should notify the admin to remove all blocks tested from your site.

Overclocking CPU's on an SMP box is extremely dodgy, there is really almost
no room for tolerance on the bus clocking.
