How to ‘increase/ Max/ Optimize/ Tune/ Boost/ Improve’ Hashrate Tesla V100 16 GB Mining Conventionally, a year ago, mining became again a popular and profitable business, people again started talking about the Ethereum and Bitcoin cryptocurrencies, everyone rushed to buy video cards and ASICs.
If everything is clear and stable on the market with ASICs, then various questions may arise in relation to video cards, for example, what hashrate does it give out on a particular algorithm, and what is the profit from this. This article will present a table with the hash rates of different video cards on popular (profitable) algorithms for 2021 (and of course for the next 2022, until new GPUs come out).
NVidia NVLink Tesla V100 16GB HBM2 Crypto Mining Benchmarks
Over the past few years, many new models of video cards have been released, and with each subsequent generation, their graphics cores are becoming more energy efficient. Miners, in turn, are divided into two groups: those who can mine Ethereum on their equipment, and those who cannot. The latter have to look for a profitable algorithm and cryptocurrency so that video cards continue to earn money. Let me remind you that for mining ETH you need to have video cards with at least 6 GB of RAM (VRAM), since the size of the Dag file has already exceeded 4.5 GB. Therefore, many old video cards “fell off” from Ethereum mining, but not all new ones are suitable for this business.

The most interesting thing is that under this limitation of possibilities, new cryptocurrency projects appear, the mining of which is focused on video cards with a large amount of video memory (8Gb or more), for example, Octopus, GRIN, Cortex. But there are projects that are ready to fight for a niche, attracting the attention of miners with video cards from 4 GB of video memory or less. The most striking example is the transition of Ethereum Classic from the Ethash mining algorithm to ETCHash, so that the mining of this cryptocurrency becomes available again on video cards with 3 GB and 4 GB of video memory. This also includes the recent hard fork of the old VertCoin cryptocurrency, with the new Verthash mining algorithm.

- How to mine Raven coin is also a detailed instruction.
In addition to the sharp exclusion from Ethereum mining of unsuitable video cards, at the end of 2021 there was another trouble: a gradual decrease in the hashrate of the Nvidia Geforce GTX 1000 series based on the Ethash algorithm (Dagger-Hashimoto). If at the beginning of the year the flagship GTX 1080Ti video card gave out 55 MH / s, now it gives out 50 MH / s, while it is also necessary to raise the core and memory frequencies to the maximum values, which will not have a very good effect on the crystal and batteries of the device. The drop in computing power in mining (hashrate) continues in 2021 with the transition to new Epochs (increase in the DAG file) of the Ethereum cryptocurrency. A similar situation is also developing for the GTX 1080, GTX 1070, GTX 1060 video cards.
The latest current generations of Nvidia RTX 2000 and 3000, as well as AMD Radeon RX 5000 and 6000, have so far proven themselves in mining for profit on Ethereum. Only sometimes certain GPU models can be more profitable on other algorithms, this is due both to the architecture of the chips and to fluctuations in the exchange rate of coins.
To follow the rate of cryptocurrencies, I recommend using the Binance exchange, and the profit of video cards can be checked on the Whattomine.com mining calculator.
And for those who are afraid of the transition of Ethereum to PoS, there is this article.
How to withdraw coins earned from Tesla mining
To mine on Tesla video cards, you can use video cards such as K40, K80, P-100, but you should think in advance how to withdraw earnings. This article focuses on the technical analysis of the NVIDIA Tesla K40 GPU, the possibilities that this video card opens up for mining. As for the problem of how to convert coins earned in an unusual way into rubles, it can be solved using:
- Cryptocurrency exchanges that support ruble cards and payment systems;
- Online cryptocurrency exchangers;
- Local, p2p, services that offer partners for an exchange operation;
- Telegram bots through which you can find offers to buy coins;
- Individuals;
- Cryptomats. Their number in Russia is still minimal, but the network of ATMs was also not so impressive at first. It is likely that soon cryptomats will no longer be perceived as something exotic.
When withdrawing coins, as a rule, a combination of two key conditions is necessary:
- Security.
- Efficiency.
According to these criteria, the exchanger becomes the best choice if you are not engaged in investing or trading. Then you can’t do without registering on a crypto exchange. However, even investors and traders try not to keep coins on crypto exchanges beyond what is necessary for day-to-day operations. The reliability of these sites as storage facilities seems to be insufficient, and the withdrawal is not always carried out instantly.
There are many exchanges, but a smart move would be to choose one of them in order to constantly make transactions. How to choose the best option, what criteria to follow:
- How easy is the interface to use. The design should not be oversaturated with prettiness, how to move from one operation to another – be perceived intuitively;
- How long has the exchanger shown a high volume of daily trading. If this happens over a sufficiently long period, then we can talk about a high level of trust on the part of customers;
- When did the service start, were there any interruptions. Termination of activities is usually associated with a change of ownership or problems with clients;
- How long does a transaction take. The normal indicator is no more than a few minutes, the maximum is 15-20 and this is in rare cases;
- Does contacting the technical support service bring tangible benefits, how quickly they respond to requests;
- How representative is the range of supported coins, what bank cards and payment systems can be used;
- Is there a real opportunity to participate in a multi-level affiliate program. For a client who is actively represented in social networks, there is a chance to receive passive income through a multi-level affiliate program.
Solid crypto exchanges provide isolated storage of coins and two-factor user authentication. The matbea.com service, which began operating in 2014, has gone even further in terms of security. Three-factor authentication is used here. But this is not the main feature of Matbi. By registering on the service, you get a unique service: automatically create a cryptocurrency wallet.
It is multi-currency, supports accounts in rubles, euros, dollars and about 55 of the most popular cryptocurrencies. Another advantage: interest-free transfers between wallets that are open on Matbi.
Technical features of NVIDIA Tesla K40 graphics card
The final technical features of the NVIDIA Tesla K40 video card were formed in 2013. It was during this period that this device for supercomputing began to be produced. The notable features of the device, which were noted by experts already at the time the K40 went on sale, are the following parameters:
- The assembly of the video card included not the most “fresh” (and many considered it frankly outdated) graphics processor – GK110B.
- Complete superiority over such models of video cards from the same NVIDIA: 780th, 780ti, Titan Black, Titan Z, Quadro K5200, Quadro K6000.
- Improved performance when compared with other variations of the same Tesla line: K40D, K40M, K40S, K40st, K40T.
If we compare the Nvidia Tesla K40 video card with representatives of the company’s previous device branch in relation to it, then:
- speed can reach superiority up to 2.8 times;
- the minimum superiority under equal conditions is at around 40%.
Based on all the characteristics of the model, miners can count on the hashrate in the Etash algorithm, which reaches 36 mh / s. Such performance in modern realities is considered quite acceptable. The video card looks especially attractive against the background of the fact that it is designed with support for technologies such as:
- A type of computer memory with automatic error recognition and correction is ECC.
- Streaming multiprocessor unit with increased performance – SMX Engine.
- Technology for handling interdependent processes – Dynamic Parallelism.
- Hyper-Q parallel data transfer technology.
- Another hardware and software architecture for parallel computing is CUDA.
- GPU Temperature Software Control – GPU Boost.
Profile and advanced miners value CUDA most of all, the support of which is implemented at the hardware level. The only drawback in this direction will be that the Kepler architecture, on the basis of which the Tesla K40 is based, only supports CUDA 3.5.
And this means that you will need an independent, flexible and unique setup of the miner. Otherwise, the performance will not be very impressive.
Specifications for AMD graphics cards
Specifications are important, but first of all, you need to know the hashrate of video cards. The table shows the performance of AMD and Nvidia models on the most profitable mining algorithms. Key characteristics when choosing a graphics card
Specifications for Nvidia graphics cards
The best alternative to mining is to buy cryptocurrency on the stock exchange, as history shows, in the long run it is no less profitable, but at the same time much easier, faster and more reliable.
GPU mining requires the most powerful graphics cards, usually the latest Nvidia and AMD models. Of course, they are not cheap, but they will become a kind of down payment, which will later pay off, and the profitability of old lines can fall so quickly that you do not even have time to recoup the equipment.
It is better to use rigs for 4-8 video cards.
But if you love computer hardware and certainly want to build your own GPU farm, carefully read the recommendations and models of video cards below in this publication.
Element base of the video card Nvidia Tesla K40
You can describe such a characteristic as the element base of the Nvidia Tesla K40 video card with the following list:
- the main computing power is concentrated in an advanced chip with the following marking – GK110-897-B1;
- the video memory parameter of the device is provided by a number of Hynix H5GC4H24MFR-T2C chips, which are located on both sides of the plan and expand the memory up to 12 GB with a high-speed GDDR5 standard;
- the video card performs functions using two PWM controllers – NCP81208 (manufacturer – On Semiconductor) and APW7142 (manufacturer – On Anpec Electronics);
- as voltage regulators, models from GStek – GS7103 are used.
How to start mining on Nvidia Tesla K40 graphics card?
For those who want to figure out how to start mining on the NVIDIA Tesla K40 video card, it is recommended to use the models released in the revision under the name K40c. This variation will please those who mine cryptocurrency 24/7 with the fact that it has an active cooling system based on high-quality fans.
If you have the K40m model in your hands, then a significant upgrade will be required for mining. At a minimum, you will need to install custom radiators. Also, it will not be superfluous to add coolers with a mount on the front side of the video card.
Additional tips for starting mining on a Tesla video card:
- The motherboard will need to run large BAR or Above 4G Decoding (3rd generation PCI-E support is required).
- If there is a message about the lack of resources, then Windows fixes a mismatch with the above parameters.
- A similar situation will be observed on devices running the Linux operating system.
- Full disclosure of all the capabilities and functions of the video card is possible only when connected to a PCIE slot that operates in x16 3.0 mode.
- For efficient operation of the K40 model, you need from 16 GB of dedicated BAR memory.
Compare and choose the best graphics cards for mining in 2021
The best alternative to mining is to buy cryptocurrency on the stock exchange, as history shows, in the long run it is no less profitable, but at the same time much easier, faster and more reliable.
Table with a rating of video cards for mining for 2021 (read more…)
When assembling a mining rig, a configuration with 4 identical video cards is most often used. These are the most stable systems that bring a minimum of problems during operation and configuration, and motherboards with 4 PCI slots are cheaper and more often appear on sale.
NVIDIA Tesla K40 video card hashrate when mining
When studying such a parameter as the hashrate of the NVIDIA Tesla K40 video card during mining, it is important to take into account the significant age of this model and the technical limitations associated with it. Particularly stands out against this background is the lack of support for CUDA above 3.5. But most modern mining programs simply do not run in the presence of CUDA with a version that is older than 5.0.
It is worth forgetting that popular miners without a built-in upgrade option and open source are suitable for this video card. These include:
- Nanomainer;
- NBMiner;
- GMiner;
- Verthashminer;
- CryptoDredge;
- T-Rex;
- others.
Without significant improvements, complex individual settings and a professional approach, from algorithm to algorithm, the video card produces not the most impressive results that do not correspond to its actual power ceiling – from 1.8 mega hashes (through PhoenixMiner when mining Ethereum) and up to 7-11 mega hashes ( via Claymore Miner based on Etash).
And this despite the fact that iron at its peak and under normal conditions should produce a stable 34 mh / s.
Power consumption
Its only drawback is lower performance compared to the leaders.
1) Nvidia RTX 3080
Card can achieve a maximum hash rate of 90 Mh/s. This is the best result of all in the ranking. Using multiple Nvidia RTX 3080s can be effectively used instead of a large number of other less efficient GPUs in the same farm.
Miners have relatively little choice. If we do not choose ASIC, then we are looking at video cards. And if we want a video card, then it’s either AMD or Nvidia. They are also called “red” and “green”, respectively. Each has its own advantages, disadvantages and predisposition to certain cryptocurrencies.
Cryptocurrency mining on a Tesla car
Finally, let’s dilute a little technical article with interesting and more exotic terms, as well as entertaining data about what constitutes cryptocurrency mining on a Tesla car.
It turns out that Tesla Model S can be improved for mining in a specific way. For this you need:
- completely empty the trunk of the car;
- install in it a classic farm of asics or video cards for mining Bitcoin or the same Ethereum (or any other cryptocurrency);
- connect all equipment to the electrical power system of the Tesla car.
This option is perfect for those who want to save money. The fact is that in many countries environmentally friendly electric transport is being promoted. Based on this, there are both big discounts and completely free filling/charging stations for Tesla and other similar vehicles.
Those who purchased a car before the beginning of 2015 were especially lucky, because. Some stations (for example, Supercharger) give such people the opportunity to recharge their Tesla charge unlimitedly.
The current characteristics of the car suggest the following:
- Trunk capacity allows you to install a farm with up to 16 video cards.
- The daily consumption of the farm on a Tesla car will reach 57 kW.
- The indicated volume of consumption is comparable to the energy required to overcome about 300 km in a Tesla car.
