I have a rig with 6 RX 480
What should driver should I use?
Sometimes I mine ethash (ethereum). Sometimes I mine equihash (zcash).
Obviously I can't change driver everytime I switch.
What driver should I use that's best for both?
Where can I download both of your miner? I didn't see windows version of the miner in drive link.
I'm not sure if it works, maybe you can try dual-boot. OS1 when you want to mine ETH that contains 16.11.5 drivers and another os, when you want to mine ZEC. But gpus will be using same bios, unless they support dual bios like Nitros.
