Fist of all i should thank the dev for making the vega very profitable again

Here is what i did

6x Vega 56 (MSI Airboost OC)
Asus B250 Mining Expert Mobo with PCI-E 1x risers and Gen3 in BIOS

1. Freshly Installed Ubuntu 16.04 Desktop (http://releases.ubuntu.com/16.04/)
2. Followed the ROCM AMD Driver Installation (https://github.com/RadeonOpenCompute/ROCm)

Created a Fan Control Script (amd-fan.sh)

#!/bin/bash
/opt/rocm/bin/rocm-smi -d 0 --setfan 150
/opt/rocm/bin/rocm-smi -d 1 --setfan 150
/opt/rocm/bin/rocm-smi -d 2 --setfan 150
/opt/rocm/bin/rocm-smi -d 3 --setfan 150
/opt/rocm/bin/rocm-smi -d 4 --setfan 150
/opt/rocm/bin/rocm-smi -d 5 --setfan 150
exit 0


No other Overclocking as it does not improve my hashrate but the Power consumption but with the stock settings and fan limit each card is consuming 150W so total 900W

At present mining Gincoin with angrypool and so far happy with the returns about ~$35 a day and miner is very stable, actually impressed with it

Will play with OCs soon and update

I must say Vega is pretty stable on linux, i have been mining Haven, Loki on windows and i know how hard to keep watching the miner crash, thanks a lot Dev @todxx
