Okay thank you very much for your answers.
I'll install the AMD Mining drivers and run PixelPatcher and hope it works fine with my modded bios.
I'ne not heard about the AMD Relive drivers 17.7.2 before in terms of mining, I guess the Blockchain drivers are far better anyway?

I don't use the original driver AMD. Before the upgrade I also ran the patcher to resolve the error 43. The new driver has no conflicts. The BIOS I installed updated. Each GPU RX 480 8 GB Sapphire provide a stable rate 29.850 Mh/s + 840 Mh/s DCR. 6 GPU 165 Mh/s in dual mining it is normal.

To mine ETH or ETC you need to use the AMD blockchain drivers. Those are the only drivers that fix the epoch Dag hash rate drop. You also need to use Afterburner 4.4.0 beta 16 or higher with the blockchain drivers or the AMD Relive drivers 17.7.2 or higher, since AMD changed the API starting with that driver. You may also need to use the pixel patcher to bypass the driver signature check with a modded Bios. Otherwise the cards will show a code 43 in the Windows Device Manager and they won't work.

Hello mining community,
I have a mining rig with 6 RX480s and I want to get the highest hashrate I can get.
My cards are:
2 XFX RX480 GTR 8GB
4 Powercolor RX480 Red Devil 8GB
I have Bios modded the cards and the rig got a hashrate of 165 Mh/s on Ethereum. MSI Afterburner doesn't want to start since the cards are Bios modded (no clue what I did wrong to cause that issue). My Drivers version is currently 16.9.2.

Now my question is:
Should I reinstall the original Bios and install the new mining driver beta from AMD and overclock the cards
or
Should I keep the modded Bios and try if the mining driver work?

I switched from ETH to ETC yesterday and my hashrate dropped from 165 Mh/s to 135 Mh/s and I hope to get back to my usual hashrate or even more with overclocking and new drivers but I'm not shure how the Bios mod reacts to this.
