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.
