Here comes another tutorial, this time i will show you how to modify the Sapphire Nitro+ RX 470 8GB OC’s BIOS and Flash it with ATIflash to get a better mining hashrate! My previous tutorial was about the 4GB version and it can be found at this link!
Once again i spent days to find what would bring this card to the top and hopefully one of this BIOS will give you a better mining hashrate!
If flashing BIOS goes wrong like power down, pc shutdown, blue/black/white screen.. no worries, in this tutorial you will find how to recover the GPU
To remove all doubts about the GPU model, the ROM is for this version only

That’s it 🙂 Play with the clocks, lower the mV and get the best hashrate and consumption of your card. And remember if something goes wrong while or after flashing the card, no worries, in this tutorial you will find how to recover a “bricked” GPU. http://1stminingrig.com/how-to-fix-re-flash-bios-of-bricked-gpu-on-rx-470-480-series/
