Manufactured Overclocked CPU

Hi, I would just like to know if you need to change the voltages in your BIOS if you have a manufactured overclocked CPU that has already been overclocked by intel before you buy it.
Thanks

Not if it is in official packaging... They would likely have legal trouble if they sold them needing those changes.

if its manufactered overclock u dont need to do anything, but then again its probably barley overclocked
