I followed the steps carefully and I checked my gpu's memory and it's SAMSUNG so on Polaris BIOS editor, I copied the strap from 1750 to 2000 and saved. Then flashed the modded bios file using ATIWinFlash app. After restarting, I noticed that my resolution became low and on "dxdiag", it's wasn't detecting my GPU. I don't know what else to do. I don't see any thread experiencing a problem like mine. For now, I restored my gpu bios to default. Hopefully someone can help me.
Happy Mining!
