Open your BIOS in Nibitor, after it checked that the BIOS is aok navigate to Fermi voltage (for fermi there are two possibilities added: Fermi volts and clocks). In the upper section of the window that opens you can raise the upper volt limit to 1.213.

Now save that BIOS and put it together with nvflash on a bootable USB stick.

Reboot.

Since you have two identical cards the whole process of finding out what to flash were is redundant.

Now just type

nvflash -i0 -5 -6 yourbios.ROM

for the first card and

nvflash -i1 -5 -6 yourbios.ROM

for the second one. Should you get a warning about write protection you just issue a

nvflash -i0 -r
nvflash -i1 -r

and retry with the flashing commands.
cool thanks a lot will try now.
