We have a farm with Palits / Gainward 1070 GPUS. They are pretty hard to find but they have fantastics stats :
- Low power consumption (very low fall of hashrate with 100w cap - best electricity ROI)
- Good hashrate (up to 500 sols)
- Low-temperature heat emission
BTW, if you have a multiple rigs farm, I advise you to use a personal statum proxy to increase security, optimise your internet connection and increase your earnings.
