What would be the best way to mod this card for better hashing rates? I see people taking about modding the bios and moving memory straps 1500 to all higher memory frequencies. Is there anything else to be done? When I run MSI Afterburner the voltage is fixed (slider disabled) and everything I have tried to enable it has failed (config file change, etc.). Here is the info from my bios. The card has Samsung memory.
