Is it OK to flash a 256k original factory bios with a 512k modded bios on a Sapphire RX 470 8gb?  I have checked them both in polaris bios editor and the data checks out OK on both.  Only the filesize is different.

doktor83 was kind enough to send me this modded bios but I can't get confirmation from him via PM if it is OK to replace a 256kb factory bios file with a 512kb bios file.
