Below you can find the best hashrates and clock settings to achieve them. Remember that these figures are provided for educational purposes and the hashrates of different video cards may vary depending on their model and manufacturer.
If you’ve got a chance to choose between several options, you should know that Samsung memory chips excel Micron models, particularly when it comes to the overclocking limit and stability at a high clock rate. NB: flashing GPU BIOS to a custom BIOS on your laptop can render it useless.

So which of the Geforce GTX 1070 models work best for mining? The truth is that most GTX 1070 video cards are already sold out (quite predictably so, since GTX 1070 is one of the best GPUs for mining). Sadly, you often just don’t have that much choice and will be forced to buy what’s available in stock. Still, here are a few facts that may help you make an educated decision, if you’re lucky enough to have a chance to choose between several models.
- Gigabyte. Some users complain that VG Gigabyte has the weakest and least reliable fans compared to the other models. However, I find Gigabyte Geforce GTX 1070 G1 Gaming a perfect choice. The three fans, even while not being the most reliable ones, enable me to maintain the low temperature.
- NVIDIA Founders Edition. While FE video cards are famous for their high hashrates, they are also one of the noisiest models out there.
- ASUS STRIX. This one is probably the most popular choice for miners. While this model is a bit more expensive than competing models, it provides you with an excellent hashrate and a quiet and durable cooling system.
- Zotac. Zotac is known to have a high hashrate and a reliable cooling system with two fans. The model received a lot of positive feedback from users.

Some people are wondering whether it makes sense to use a powerful GTX 1070 video card and a gaming laptop to mine cryptocurrencies. I would not recommend using your laptop for mining. Should anything unexpected happen to your GPU, you risk losing the entire device which is much more expensive than a regular desktop with that very same video card.
Nevertheless, if you are aware of the risks but still would like to give it a try, a laptop run on GTX 1070 can produce remarkable results. Here are the figures I’ve got:
- 25.8 MHS/sec for Ethereum mining at default clock and power consumption at 147W.
- 30.1 MHS/sec for Ethereum mining (boosted to + 150/+ 700) with GPU temperature exceeding 80°.
It is not an uncommon issue for miners to face the problem of a very low – about 2.5 MHS/sec – hashrate upon buying GTX 1070 and installing the latest drivers from NVIDIA. If you’ve found yourself facing the same challenge, don’t fret as there’s an easy fix to it. Everything boils down to some issues with Windows 10, not with the video card itself, as many miners are quick to assume.
You’ve got two possible solutions to this problem:
- switch to Linux;
- update Windows 10 to v.1703 which eliminates this bug.
Does it make sense to buy a GTX 1070 video card for mining purposes? Absolutely. We believe that despite the recent (and significant) price hike following growing demand on the part of miners, GTX 1070 remains an excellent investment.
It’s also worth noting that GTX 1070’s capabilities go well beyond mining. It is the most productive and affordable video card for gaming and stands out nicely among GTX 1060 and the more expensive GTX 1080 and GTX 1080 Ti. Moreover, gamers would be happy to buy this video card from you, should you like to sell it.
In 2017, buying a video card for mining is going to be one of your costliest purchases. You will experience this first hand while trying to source one of the top video cards.
Building farms using GTX 1060 is still a popular option for lots of miners but the overall trend is shifting everyone’s attention towards GTX 1070 and GTX 1080. The cost of these cards in Eastern Europe is twice their cost in the US and the EU.
We have acquired the MSI GTX 1070 Gaming X 8G card which, as of now, has been mining Zcash for a week. Here’s what we were able to achieve with it as well as our insights into how exactly the mining process works with MSI GTX 1070 Gaming X 8G.
The video card itself was deployed on a very old, yet practical system. The card was based on Asus P5/EPU motherboard (quite a while ago, the network port and sound chip burnt themselves out following the lightning strike and were replaced by the boards in PCI slots), 8 GB RAM (four slots two GB each), an Intel Core 2 Quad Q6600 processor working at default 2.4GHz. In other words, this is a classic office computer that is not effective for neither games nor other complex tasks.
We used this system to install MSI GTX 1070 Gaming X 8G and initiate mining.
1. Before actually mining, we have explored the possibilities provided by the video card as well as the best revenue-generating cryptocurrencies.
We installed the popular NiceHash Miner program which enabled us to find out the optimal currency by calculating preliminary benchmark figures.
The optimal mining algorithm (as of mid-June) turned out to be Equihash algorithm which would allow us to earn about $4 per day.
Using the online hash calculator provided by whattomine.com, we also figured out that Equihash algorithm enabled us to mine Zcash (ZEC), Zencash (ZEN), Hush (HUSH) and other cryptocurrencies. We decided to mine Zcash which allowed us to earn about $4-$5 a day.
2. Boosting the video card to reduce power consumption which, in turn, would result in the lower temperature and increased frequency of the chip core and memory (Micron). To boost the card, we used MSI Afterburner.
To come up with best settings, we turned to discussions on various forums and eventually decided to go ahead with the following:
- power limit reduced to 75%;
- Core Clock set to +200 (2025 MHz);
- Memory Clock set to +600 (4400 MHz);
- cooler speed set to 70 to 90 (depending on the weather outside).
The above settings allowed the video card to mine Zcash at a speed of 477-490 Sol/s and power consumption of over 200W. The temperature of the core equaled 60°-65°. The system was operational for two weeks and started resetting the settings soon afterward.
The second revision of system settings:
- power limit reduced to 60%;
- Core Clock set to +191 (2012 MHz);
- Memory Clock set to +581 (4387 MHz);
- cooler speed set to 70 to 80 (depending on the weather outside).
Mining speed amounted to 480-490 Sol/s and power consumption amounted to over 150W. The temperature of the core equaled 56°-60°.
Therefore, we were able to reduce heating, power consumption and noise caused by the fans.
One can often come across posts from miners where they talk about squeaking of chokes for this category of video cards. However, we have observed that MSI GTX 1070 Gaming X 8G produces less noise than the system unit cooler, even at a speed of 80.
It’s worth noting that each video card requires different boosting options so the below tips will come in handy:
1. start by boosting the memory of the video card. The limit for the Micron chips is typically +600 (4400-4500 MHz);
2. the next step is boosting the core. The limit is typically +200 (2050 MHz);
3. try to reduce the power limit to less than 75%. This will significantly reduce the power consumption by the video card;
4. try not to heat the video card to more than 65°-70°. This will help you increase its durability and avoid warranty repairs which normally last for about 3-4 weeks (just think about the losses you’ll incur).
The final tip: if you’d like to track the power consumption, add -pec at the end of the settings line in xxxxx.bat file.
