How to Get 30-31 MH/s with your RX480 8G AMD Sapphire Nitro+ using a Bios Mod for Ethereum Mining XFX MSI Monero

Do you mine cryptocurrency? Have a Sapphire Nitro+ AMD RX480 8G GPU? Interested in getting a better hash rate?
If so... it is time to modify your bios to increase your hashes per second!
This should increase hashrate for many alt coins including but not limited to Ethereum, Monero, Lbry and more!

It is very simple.

1. Download Polaris Bios Editor
2. Download AtiFlash 2.74
3. Download and install the most recent AMD drivers (16.9.1 or 16.9.2 or 16.10.1 or newer)
4. Switch the Bios Switch on your GPU to the Silent Mode side (side where the HDMI and Display ports are)
5. Remove any other GPUs that are connected to your motherboard.
6. Back up your "silent mode" bios using Atiwinflash
7. Modify your backed up bios with Polaris Bios Editor by copying hte 1750 timing strap to the 2000 strap.
8. Open Atiwinflash as Administrator again
9. Click LOAD and select your modified bios.
10. Click Program and Flash your card using Atiwinflash
11. Restart
12. Open Wattman and overclock your memory as high as you can without crashing your computer ( I overclocked mine to 2200 MHz )
13. Start Mining at 30+ Mh/s

Walk through with images:
Hash rate BEFORE modification:

Switch your bios switch to silent mode (the side nearest the display ports)

Remove all but the GPU you want to flash from your motherboard

Open ATIWINFLASH as ADMIN and click on SAVE to save your original Bios

Open Polaris Bios editor, Open your saved Bios rom, copy the 1750 TIMING VALUE and paste it over the 2000 TIMING VALUE, click on save and save your modified bios with a new name which you can identify as the modified rom. Remember to type in ".rom" at the end of your name so it saves as a rom file.

Open Atiwinflash as Administrator again and click on LOAD.

Select the modified bios you just created and click open.

Now click on PROGRAM to Flash your GPU

Once it is finished, restart your computer.

You should now be hasing at 27-28 Mh/s

To get 30-31 Mh/s open WATTMAN and overclock your memory as high as you can without crashing your comptuer.

You should now be hashing at 30-31 Mh/s
