I just got a couple of MSI Armor rx480 4GB cards (https://www.msi.com/Graphics-card/Radeon-RX-480-ARMOR-4G-OC.html)

I need help in reaching the best speed on both ETH/zCash with these GPUs at the lowest possible power. The memory type is Hynix

I have searched the forum here for help and even Google but it seems that there is no reliable/helpful advice with this card in particular.

0.5 reward to the person that helps the most
