Unlocking the GTX-590 GPU BIOS voltage
Making your voltage adjustments

On the GTX-590 Classified the voltages are locked @.913v, and rarely provided any stable Overclocking. The most suitable voltage found was @.963v with a cap of 1.063v.
Images below demonstrate making adjustments to each .bin file by clicking on “Tools”, then “Fermi Voltage”. Adjustments will be made to the “Settings 2:” row, as “Settings 0: and 1:” are used for lower power management modes.
After both .bin files have been updated with the desired voltage modifications, simply click “Apply” and proceed to “File” and selected “Save BIOS…” – saving each file into your “ROMs” folder created earlier. Again to lesson any confusion it is best to give the .rom files their own specific naming convention:
