There is a way, but it is extremely risky, so be careful. You must flash a new GPU Bios onto the cards EEPROM memory, thus changing settings and max abilities of the card, etc.
BE WARNED, ALTHOUGH THIS WORKS, IT COULD ALSO FRY YOUR CARD, OR CAUSE YOU PC TO CRASH ANDGPU TO MALFUNCTION UNTIL YOU REVERT THE EEPROM FROM ANOTHER PC!! YOU HAVE BEEN WARNED!!!
