I am unable to modify the BIOS with Polaris

[cost.basis]

I am unable to use one click mod in Polaris.  I have a Sapphire Technology Pulse Lite Edition RX 580 8GB Samsung GDDR5.    I backed up my video card BIOS with ATIwinFlash.   The backed up ROM is 256k in size.  I loaded the backed up ROM in Polaris. Polaris is unable to identify the VRAM.  GPUZ recognizes memory as Samsung.  What am I doing wrong? Any suggestions.  Thank you.

Not really the right forum to be asking this. This isn't hardware support per se. I'd suggest you click the "move topic" link in to the bottom left and select one of the Mining Forums... maybe "Hardware"?

Failing that, a dedicated hardware forum like Tom's Hardware or Overclock.net might be your best bet.
