Getting a maximum in Ethereum mining on Nvidia GTX 1070 in 2017

If you don’t want to pay more for the NVIDIA GeForce GTX 1080 Ti graphics card you might want to look at the NVIDIA GeForce GTX 1070.

So today we are going to be looking at the lower cost GeForce GTX 1070 graphics card. This card in-stock for purchase at most retailers and prices start around 435 euro in Europe ($413 in US) and it has 8GB of GDDR5 memory and depending on the model you should have a default hashrate of around 26 Mh/s.

Once you overclock the memory you should be able to get the hashrate on the GTX 1070 up to around 33 Mh/s. With six of these cards in a mining rig you are looking at roughly 198 Mh/s for your 3000 euro investment ($2800 in US) in buying six GeForce GTX 1070 video cards.

We did some testing on the MSI GeForce GTX 1070 GAMING X 8G video card on Claymore’s Dual Ethereum AMD+NVIDIA GPU Miner v9.8 and got some pretty interesting results that we wanted to share with you. We also used the EVGA Precision X OC utility for overclocking.

This is the hashrate that we had by default without applying any overclocking:

Below you can find the results that we had for memory overclocking. The temperature, fan speed and the power target were more or less the same: 70°C (158 F), 54% for fan and 100% power target.

Note that for the Estimated GPU power we just subtracted the overall power consumption at the wall outlet of the system at idle from the overall system power number while mining.

Memory offset	System power	Est. GPU power	Hashrate
0 (Default)	180	100	26.5
+500	210	130	30.3
+600	215	135	31.1
+700	220	140	31.8
+800	225	145	32.5
+850	225	145	32.9

We managed to overclock the MSI GeForce GTX 1070 cards memory up to +850 MHz! Our hashrate mining Ethereum went from 26 Mh/s to almost 33 Mh/s! Most impressive was the fact that the GeForce GTX 1070 was only using 100 to 145 Watts of power our temperatures were 70°C or lower and the fans were about 54% that brings minimal noise. Our card didn’t like running the 8GB of GDDR5 memory at +900 MHz at all because we started to get the artifacts on the screen immediately, so we lowered it down to +850 MHz as that was rock solid.

So we found the memory offset for our MSI GeForce GTX 1070.

The next step is to try to reduce the power consumption by lowering the power target in EVGA Precision X OC.

Power target	System power	Est. GPU power	Hashrate	Temperature	Fan speed
90	220	140	32.9	71	56
80	215	135	32.9	71	55
70	200	120	32.8	68	50
60	170	90	32.8	65	40
50	160	80	32.7	63	38

By lowering the power target we managed to go from 220 Watts of power at 32.9 Mh/s to just 160 Watts of power at 32.7 Mh/s. As you lower the power target the hashrate does take a slight performance hit, but loosing roughly 0.2 Mh/s for cutting the power use by 60 Watts is pretty slick. We also managed to drop our temperature from 71°C down to almost 60°C and the fan speed from 55% to 38% that brings the silence to the mining!

So, we are mining Ethereum on MSI GeForce GTX 1070 GAMING X 8G getting 32.7 MH/s on a system using 160 Watts (GPU uses in mining 80 Watts) of power with almost no fan noise. That is pretty impressive results!

But let's look at the profit from Ethereum mining on our not overclocked GeForce GTX 1070.

The profit from Ethereum mining on our overclocked GeForce GTX 1070 with 50% of power target.

In the reality of 2017, the mining on one GeForce GTX 1070 that has the memory overclocked will make you about 385 euro ($460) a year in profit based on Ethereum prices today ~237 euro ($284). Lowering the power target will reduce your power bill by a 45 euro ($53) a year, but it means you’ll mine slightly less a year. If you don’t care about the power bill, heat and noise you are still best off leaving the power target close to 100%, but if you want silence and less heat in your home lowering the power target isn’t a bad idea.

Please check this profitability calculator yourself because the difficulty and the exchange rate of Ethereum are always changing and don't forget to enter your correct price for the electricity to see more accurate results.

Of course making 385 euro ($460) per year is not an impressive result, but it is a reality in September 2017. And it means that you can return your investments in the MSI GeForce GTX 1070 GAMING X 8G in 13 months of Ethereum mining.

If you are going to build a mining rig with six of these cards with the total hashrate about 196Mh/s and the total power consumption of 560W, your profit will be today around 210 euro ($255) per month or 2500 euro ($3000) per year which is a really good result in September 2017.
