I'm trying 2 days (more than 20 hours total) and cannot make this miner to work. I've been following guides but without results. Tried Ubuntu, Kubuntu, Xbuntu (16.04) and 17.50 drivers and 18.10 drivers. Tried without ROCm, with ROCm included with drivers, ROCM from Github. Most I managed is for miner to report that there are correct number of gpus but cannot initialize them or something.
What is power consumption for vega 56 on stock settings (flashed to vega 64)? If my psu cannot handle 5 vega cards, better not to lose time any more.
