FYI - My groups's AMD farm is mining XMR and CN7 with Claymore's XMR miner v11.3 - thanks to Claymore, since v11.3 the miner is completely free and has no developer fee.
For the time being, is it more profitable to mine the ETH than the XMR? I have a few 7970, I mine the ZEC. I have R9 390, mine the ETH.
For the r9 390s, its better to mine ETH. For the 7970s, ZEC is your best option.
The group's AMD farm was mining ETH since 2015/16 - consisted of R9 Nano (currently ZEC mining due to its HBM v1 at the NVIDIA farm), R9-390, RX480, RX470 --- switched to XMR since earlier this year. I didn't bother to flash back the RX cards to stock, but just cranked down the memory. Since mining XMR - our power bill dropped at least 30%, temps at the farm dropped by 6-7c and decibels became bearable. Consolidated almost 60% of the farm to riser-less with 6 and 8 slots PCI motherboards from ONDA, Colorful and K35. That saved a lot of SMOS subscription.
Note: if you have 1080tis, getting them to mine ETH with the Pill is worth it. I have been putting 2 of my strongest 1080ti rig to mine ETH to hoard.
