EVGA provides you with products and software that may help you achieve higher performance.
 
However:

• They do not give direct advice for overclocking over the phone or by email.
• They do not guarantee stability or success from any amount of overclocking, just like any other manufacturer.

EVGA will give you the tools and warranty to experiment with your hardware, as long as no physical damage takes place.  After that, it's up to you and the advice of your peers to figure out what works best for your system.  This is one of the biggest reasons why the forums are a valuable tool for both EVGA enthusiasts and overclockers alike.
