Hi Kris,
It's called over clocking and it's done within the BIOS, it's best to only overclock to about 25-30%+ of the normal running as it'll cause it to heat up faster and it'll shorten CPU life much quicker above that, my LGA 1156 is only about 2 years old and is over clocked to 3.12ghz, it is also starting to die, it'll max out about 3.6ghz, but I'd rather extend it's life.
However I have no problems in TS12 SP1 HF3, here's a screenshot

The only time I have crashes is when a asset has a bad script which causes a fatal error then crashes to Desktop, another cause of bad performance is assets that take up allot of resources, mainly those that are really high poly with no LOD's and have 40+ textures per model.
Cheers.
