Overclocking i5 3570k/i7 3770k

[insense]

Hi,

I have a question about oc'ing. I just got my 3770k and i am intending to sell my old 3570k. My question is i had it oc on 4.7Ghz and as i saw after i've puted 3770k in it was automatic 4.7ghz so i'm guessing it's all in the bios. Is the oc of 4.7 actually in the cpu ( i dont wanna sell someone a 4.7ghz cpu on a stock cooler) or is it all in the bios and how someone has setup the frequency?

It won't overclock till bios is set up to do it.
