Rivatuner will only take you so far ... the idea is to enhance the card's headroom using aftermarket cooling to wick off the additional heat generated from the high overclock/voltmods. This is gonna be a tough one, since PNY has used such a different PCB layout compared to the reference, but all it takes is finding one techno-nerd with the knowhow in combination with this PNY card to make it happen. Good luck !
