Is it any good for mining? We will take a closer look at the GTX 1070 for mining, test its overclocking and also compare it with other GPUs.
Geforce GTX 1070 specifications:
- GPU architecture: Pascal
- Video memory: 8 GB GDDR5, 8Gbps
- GPU boost frequency: 1683 MHz (1.4x)
GTX 1070 – mining performance
Best hashrates and frequencies to achieve them are given below. Keep in mind that the numbers are provided mainly for reference purposes and GPU hashrate may vary depending on the lot and the manufacturer.
If you have a choice, you should know that Samsung memory chips are superior to those of Micron, especially with regard to overclocking limit and stability at high frequencies. Attention: upgrading GPU BIOS in your laptop to a custom BIOS can make your laptop unoperational.

Which of the Geforce GTX 1070 models is best for mining? In fact, most GTX 1070 GPUs are already sold out (cause GTX 1070 is one of the best for mining), so in most cases you simply do not have a choice, and you have to buy what’s available. But here are a few facts that may help you decide (if you have a choice, of course).
- Gigabyte: users complain that it has the weakest and the least reliable fans (in comparison with competitors). But personally for me, Gigabyte Geforce GTX 1070 G1 Gaming is an excellent choice, because of the three fans installed on it (though not the most reliable ones) so it operates at a low temperature
- NVIDIA Founders Edition. Although FE GPUs have high hashrates, they are noisy
- ASUS STRIX. It is probably the most popular choice among miners. Although this model is slightly more expensive than competitors, you can get a good hashrate and a quiet and durable cooling system
- Zotac. IGood hashrates and an excellent cooling system with 2 fans. Quite a lot of positive feedback from users

Mining with GTX 1070 (laptop version)
Some people ask: “Is it possible to use the powerful GTX 1070 in my gaming laptop for mining?” Personally, I would not recommend using a laptop for mining, if suddenly something happens to your GPU, then you can lose the entire gadget that is much more expensive than a desktop with the same graphics card.
However, if you understand the risks and want to still try laptop mining, you can get good results.
I managed to get the following results:
- 8 MHS/sec Ethereum mining with run-off frequencies and 147W power consumption
- 1 MHS / sec Ethereum mining in overclock (+ 150 / + 700) with GPU temperature exceeding 80°
How can we solve the 1070 hashrate problem?
If you buy a new GTX 1070 and install the latest NVIDIA drivers you can face the problem of a very low hashrate -2.5 MHS / sec. Don’t worry, it is easy to fix it. This does not mean that your GPU is faulty, you just have a problem with Windows 10.
There are two ways to solve this problem:
- use Linux
- Upgrade Windows 10 to v.1703 – which fixes this bug
Is it worth buying a GTX 1070 GPU for mining? Of course. In our opinion, although the prices for this GPU have increased significantly recently due to high demand from miners, it is still an excellent investment.
Don’t forget that it is also the most productive GPU for gamers and is the golden mean between the GTX 1060 and the more expensive GTX 1080 and GTX 1080 Ti. Most likely you will be able to sell it to gamers in the future.
Overclocking the MSI GTX 1070 Gaming X 8G for Mining
In 2017 buyig a GPU for mining is as relevant as ever, you will be able to feel it when you try to find one of the top GPUs on sale.
GTX 1060 farms are still popular, but next generation gtx 1070 and gtx 1080 are gaining weight. The cost of these GPUs in Eastern Europe is twice their value in the US and the EU.
We have a MSI GTX 1070 Gaming X 8G, which has been mining Zcash for a week now. Let’s look at the results and how MSI GTX 1070 Gaming X 8G can be used for mining.
The GPU operates on an ancient, but practical system – Asus P5 / EPU motherboard (where the network port and the sound chip were burnt by lightning and replaced by cards in PCI slots), 8 GB RAM (four 2 GB each), an Intel Core 2 Quad Q6600 processor at 2.4GHz default frequencies. Today this is a classic office computer that is not relevant for games with other complex tasks.
In this system, we inserted the purchased MSI GTX 1070 Gaming X 8G and launched the mining process.
- Before starting the actual mining, we studied the GPU capacities and the currencies which will bring the most revenue.
We installed the popular NiceHash Miner which allows you to find the best currency for mining through the launch of a preliminary benchmark.
The most optimal mining algorithm (mid-June) was Equihash (about $ 4 per day).
Using the online hashrate calculator on whattomine.com, we learned that Equihash can be used for Zcash (ZEC), Zencash (ZEN), Hush (HUSH) etc. We chose Zcash, which allowed us to receive about 4-5 dollars per day.
- GPU overclocking.
The purpose of overclocking was to reduce power consumption, which would lower the GPU temperature, increase frequency of the chip core and memory (Micron). We used the popular MSI Afterburner.
Based on information that we got online, we used the following settings:
- reduced the Power Limit to 75%
- put Core Clock to +200 (2025 MHz)
- Memory Clock to +600 (4400 MHz)
- cooler speed from 70 to 90 (depending on the weather outside)
With these settings, the GPU produced Zcash at a speed of 477-490 Sol/s consuming more than 200W. The core temperature was at 60-65 degrees. This system worked for two weeks after which it started resetting.
The second settings:
- Power Limit reduced to 66%
- Core Clock is set to +191 (2012 MHz)
- Memory Clock to +581 (4387 MHz)
- cooler speed from 70 to 80 (depending on the weather outside)
The production rate is 480-490 Sol/s consuming more than 150W. The core temperature is 56-60 degrees.
Thus, we have reduced temperature, power consumption and fan noise.
Often you can find messages about chokes squeaking under load, but our MSI GTX 1070 Gaming X 8G even with cooler rpm 80 is less noisy than system unit cooling.
It is worth noting that each GPU has its own specific features of overclocking. Here are some general tips:
- First, usual memory overclocking limit for the Micron chips is about + 600 (4400-4500 MHz)
- Next, accelerate the core frequency, the limit is usually around +200 (2050 MHz)
- Try to lower the Power Limit to less than 75%, this will significantly reduce the GPU power consumption
- Check that the GPU temperature is under 65-70 degrees. This will increase its period of work, exclude warranty repairs which will take about 3-4 weeks (just calculate the losses)
A little tip: if you want to monitor mining energy consumption, write -pec at the end of the line with in the file xxxxx.bat.
