When the GTX 1070 Ti was announced, most of us were intrigued on how the card would perform for mining.
First tests gave rather confusing results since every tester would post a different hashrate and power consumption numbers. As it always happens with GPUs that are not binned, no two GPUs can be overclocked the same. Or at least, the overclocking process isn’t as straightforward as we’d want it to be.
That being said, I’ve invested some time and effort into my 1070 Ti’s and the results are at least satisfactory.
On factory clocks, the card hashes 26.3 MH/s with a power draw of 120 W from the wall. This is not a number we can be thrilled about, especially considering the card price.
Overclocking it too much resulted in stability issues which again lowered the output hashrate.
However at the end of the day, I’ve found some sort of consensus between power draw and hashrate.
I’ve tested all of the popular dual mining combinations. Lbry, Decred, Pascal and Siacoin seem to work well with Ethereum. Thanks to the undervolting margin, the card can be overclocked and used for dual mining while keeping power consumption between 110 and 120 W.
This means that after the tweaks you can get a GPU that consumes less than on factory settings while at the same time hashing 20% more ETH plus a secondary coin.
I took the time to compile a list of hashrate and power consumption for each combination. You can check it here: http://1stminingrig.com/nvidia-geforce-gtx-1070-ti-mining-performance-review/
Also, I’ve included screenshots and photos just so you can stay assured that it’s all legit.
