MSI Afterburner unable to change voltage ?

I tried to change my HD 7970 voltage, the default is 1113 and I want to change it to reach a higher overclock. But when I adjust the slider on MSI Afterburner, and hwne I click Apply, it always revert back to 1113. I have enabled unofficial overclocking, disabled ULPS. This is also same with trixx. Is there any way to change my voltage ? My card is Club3d HD 7970 royalQueen

  1. a lot of 7970 have been voltage locked

    absolutely nothing i have tried on my gigabyte 7970 will allow increasing voltage

    1113mhz is a pretty high clock speed anyway

    1113 mV, not Mhz. I can't pass 1120 Mhz Or it will crash.
  4. Now I'm trying to flash my GPU BIOS to unlock it, but when I flash it and reboot it says that no graphic driver installed, there is an exclamation mark on device manager, and after reinstalling driver it's the same, so i flash to stock. Did I do something wrong ? I followed this to flash my BIOS (http://www.overclock.net/t/1353325/tutorial-atiwinflash-how-to-flash-the-bios-of-your-ati-cards). Also, can I flash using BIOS from different brand, like from ASUS ?
  5. i tried flashing different bios to get more voltage including force flashing different maufacturers bios

    just made the card totally unstable
  6. SO there are no way to unlock my card ?
  7. not as far as i am concerned--if its the same as my card then no

    what really annoyed me was there was no mention of voltage locking on gigabytes website

    or on the retailers site who sold it to me

    the revision 1 of my card could be overvolted and overclocked to about 1300mhz

    i think too many were failing so voltage locking was the result
