    Running a pair of Gigabyte Windforce 280x cards. GPU-Z says their BIOS is the same version, however I noticed the primary card's voltage sits around 1.16V whereas the second card goes to 1.2V on load.

    I can't change the voltage in Afterburner either, so wondering what else I can do... Modified BIOS perhaps...?

    So I've managed to up the voltage in Trixx to 1.2V, same as the second card.

    Not sure why the primary card was set to 1.16V (Trixx said the same thing).

    Any suggestions on modifying the BIOS to run the correct voltage...?

    Also, I dumped a copy of the BIOS, and it said something about UEFI. Should this concern me?
