Save the -Original- BIOS before flashing
*the first rule of BIOS flashing, is you do NOT talk about BIOS flashing
Upon any warrenty return to EVGA, the -original BIOS must be -on the card-
If for ANY reason you attempt to return a card to EVGA without the original BIOS, it will be returned to you -its warrenty void-
*Personally I think that such voltage modded BIOS for the 600 series is ill-advised, unless you can afford to throw it in the trash and buy a replacement. If you can afford it, mod away
