Unlocking the GTX-590 GPU BIOS voltage
Saving the .bin BIOS files
Using GPU-Z you will first need to save two .bin files (one for each GPU on the GTX-590 – or simply one .bin file if you are flashing a single-GPU graphics card). GPU-Z will save the GPUs BIOS files in .bin format, which we will place in our “BINs” folder for later use – as well a backup of the BIOS.
The above two images demonstrate how to save your graphics card BIOS, using GPU-Z, while the image on the right demonstrates saving the second GPU on the GTX-590 graphics card.
Now save both BIOS .bin files, into your “BINs” folder using a file name convention shown below of each GPU, or whatever format you feel most comfortable with:
With both .bin BIOS files saved you are now ready to open each one with the “NiBiTor” application and make the desired voltages modifications along with saving them as .rom format, which “nvflash.exe” will be able to read in our next steps later.
