Crossfiring two different RX 580 GPUs (8 GB and 4 GB) for Ethereum mining

[primetimeseano]

Hello,

I just purchased two RX 580 GPUs for my PC. The main purpose will be Ethereum mining, but I’ll also be using them for gaming. I had to purchase two different cards due to supply limitations. Specifically, I bought an XFX GTS Black Core Edition 8 GB and an XFX 4GB. My current card is a Radeon 7970. My motherboard is an Asus Z87 Pro. My power supply is 850 W.
I understand that I should be able to crossfire the two cards fairly easily, but I just wanted to make sure and also see if anyone had any recommendations in terms of guides to follow or drivers or other software to install after I install the cards since I’ve never tried to run dual GPUs before.

Thanks!

Remember to underclock and undervolt your CPU, that'll net you negative profit while ethereum mining.
I'd put the 8GB GPU in the first slot in order to ensure proper utilization.
