unable to Flash via Polaris Bios editor while MSI afterburnr Tweaking works Fine

[parshuram]

Hi Guys.

Red devil Rx 480 8gb. Asic Quality - 68.8% (gpu-z)

the Card does not takes flashing at all other than its original rom. However when I change the Memory Clk in Msi Afterburner - 2087 it accepts the clock and mine.

While applying all the same standards in Polaris Bios editor the Card bricks.

And when the pc turns on after 2-3 attempts the card is not detected and in the device manager the card is displayed with a Yellow Exclamation mark.(Tried cleaning and re-installing the driver) . So if I flash the original Bios the card starts mining again like usual !

What might be the possible reasons?
Is there any other way to flash except atiwinflash so that the card doesn't bricks?

Thank You

P.S - Can Anyone guide me how to input the vddc of the card, benchmarked from trixx/Msi afterburner in the Polaris Bios editor.

UEFI bios will check for and will not load hardware that has an unsigned bios, and/or AMD driver also looks for a signed bios.
