yep its very vague, but if you only turn it up a tick or two you can be sure your card is still covered. EVGATech_Kyle made a second post saying this;
You would need to push it a lot more than a hair over the line to cause physical damage.
I doubt that you can even push this program to the point of physical damage at this point since we limit the amount you can up the voltage.
The is no hard and fast rule, every card will respond to the voltage boost differently.
I think hes trying to say that ifs theres no visible damage to the card like burns, melting, big hole where the gpu should be
, etc... then they'll replace it.
