Disabling the HPET timer increases your computer's mining performance

All modern computers are equipped with a high-precision timer called HPET (High Precision Event Timer), which is necessary to synchronize the operation of various equipment (sound cards, video card, processor) in multimedia tasks: video games, sound and video editors, audio and video players. The HPET timer is also known as the multimedia timer. By default, the HPET timer is enabled on all computers for compatibility, but in fact in modern computers it only increases delays in work, which affects the number of frames per second and their number for rare events in games, as well as in other resource-intensive applications, including in cryptocurrency mining.

The reason for the hashrate drop in mining on Nvidia Pascal video cards (GTX 1070, GTX 1080, GTX 1080 Ti)

Nvidia's Pascal generation video cards (GTX 1000) in 2016 became an excellent alternative to AMD video cards in mining, although until that moment, AMD products were practically the only option for mining in terms of their characteristics. However, by 2019, users who bought GTX 1070, GTX 1080 and GTX 1080 Ti video cards for mining Ethereum cryptocurrency began to notice a gradual decrease in the hash rate of their video cards with each increase in the DAG file of the Ethereum cryptocurrency. So, for example, the hashrate of the Nvidia Geforce GTX 1070 8Gb video card in 2017 when mining ETH was 30-32MH/s, and by 2022 this video card can hardly give its owner 25MH/s. For comparison, the AMD video card of those years, the Radeon RX 480, can still show 30Mh / s or more, as in 2016, and in terms of technical characteristics, the AMD video card is noticeably weaker than the GTX 1070. Because of what the hashrate decreases only for Nvidia video cards, we will tell later in this article.

What is selfish mining?

The Proof-of-Work (POW) miner reward system, like any system, has its advantages and disadvantages. The main disadvantage of POW is the possibility of a 51% attack, i.e. anyone who gets more than 50% of the power of the network will be able to take full control of this blockchain. This is the most well-known and critical POW consensus vulnerability, but there are other less critical vulnerabilities. We will talk about one of these vulnerabilities called selfish mining in this article.

How to conveniently monitor the price of gas on the Ethereum (ETH) network?

When making any transaction on the Ethereum network, the user is charged a commission, which goes to pay remuneration to Ethereum miners for finding blocks. The unit of such commission in the Ethereum network is Gas. At the moment of a sharp increase in the number of transactions in the Ethereum network, the price of gas rises accordingly, which makes the cost of transactions (deposit and withdrawal, transfer to another wallet, interaction with smart contracts) in the network much higher. The ability to timely monitor the current gas price in the Ethereum network, as well as analyze the days and times of the day with the lowest gas prices, will help you significantly reduce commission costs when working with Ethereum.

The current table with the hashrate of videocards for 2022

As of early 2022, video card mining continues to be quite profitable, despite the fact that the mining boom has been going on for over a year, which in itself is not an ordinary event. All last year, as well as several years before, the most popular and profitable cryptocurrency for mining remains Ethereum with the mining algorithm Ethash or Dagger-Hashimoto. Also in 2021 we can observe a trend of using algorithms similar to Ethash (Kawpow, FiroPow, Etchash) for mining altcoins, i.e. using DAG files to load them into video card memory. Which requires video cards with at least 4Gb of video memory to mine. Recall that Ethereum mining requires 6Gb of video memory.

Binance received a verification code in a text message. What is it?

Binance is the largest and most famous exchange where cryptocurrencies are traded (Bitcoin, Ethereum, Ripple, Doge Coin and others). If you receive an SMS on behalf of this exchange with a certain confirmation code, then depending on whether you were registered in it or not, you will need to react to such messages. If this is your first time hearing about Binance and cryptocurrencies in general, then simply ignore this message and you can add this number to the blacklist to be sure. Because it's either just someone made a mistake with the number when registering on the Binance exchange or it's a hidden advertisement for you to go to this site out of curiosity and register to buy bitcoins.

Methods for detecting Nvidia Geforce RTX 30 video cards with LHR mining limiter

In May 2021, Nvidia decided to limit all its gaming video cards of the Ampere or RTX 3000 series (except for the oldest RTX 3090 model) in cryptocurrency mining performance. Therefore, the new models announced in May: Geforce RTX 3070 Ti and RTX 3080 Ti come with a mining limiter by default, and models RTX 3060 Ti, RTX 3070, 3080, which initially had no mining limits, starting from week 22 of 2021 are also released from a new revision of the GPU, which will also have built-in protection against mining. To distinguish between old (unlocked) and new (locked) revisions of video cards, Nvidia introduced a new term LHR (Lite Hash Rate). The RTX 3060 video card stands apart here, which was originally released with a mining limiter, but later this limitation was bypassed and NVidia had to release a new GPU revision for the RTX 3060 with stronger protection against mining, but at the same time, the RTX 3060 video card, like The RTX 3070 Ti and RTX 3080 Ti do not have the LHR designation in their names, although in fact they are. It becomes even more confusing because almost all brands that produce Nvidia video cards do not indicate on the box or in the name of the LHR model whether it is a video card or not. Actually, in this article, we will try to tell you by what signs it will be possible to distinguish LHR video cards from Nvidia, produced by various brands: ASUS, Palit, MSI, KFA2, Gigabyte, Inno3d.

What is the Difference Between Coins and Tokens?

Cryptocurrencies were never as popular as they are nowadays. It is almost impossible to check the news online without seeing an article talking about cryptocurrencies or openly inviting you to buy bitcoin with Paybis.

However, many people have a difficult time when they enter the world of cryptocurrency investments, especially due to the unique and complex crypto jargon. In this sense, terms such as tokens, peer-to-peer, hodler, and others may confuse a lot of novice investors.

In this article, you will discover what the difference between coins and tokens is.

Bitcoin mining in 2021. Configuring ASIC miners

Bitcoin cryptocurrency is not just a new electronic money, but a whole technology for the secure transfer of value between people without the participation of banks, states or other intermediaries. Bitcoin became the first to use blockchain technology, in which mining or mining of cryptocurrency using computers has become one of the main elements of reliable cryptocurrency transfer, which is now trusted not only by crypto enthusiasts, but also by well-known banks and funds from all over the world. And the states using these developments are now designing new digital national currencies. But compared to national currencies, everyone can mine or mine bitcoin.

Cloud mining - Pros and Cons

If you are going to assemble your own mining farm and are faced with a severe shortage of video cards in computer stores in your city, which puts an end to your venture, then alternatively, you can consider buying contracts in cloud mining services. In this review, we will look at all the pros and cons of buying such contracts, and as an example, we will take the most trusted cloud service IQMining.

The current table with the hashrate of videocards for 2021

The beginning of 2021 was marked by another increase in interest in mining cryptocurrencies, but like the previous 5 years, only two cryptocurrencies are the main focus of miners: Ethereum and Bitcoin. Ethereum, as before, is mined by miners using video cards, and Bitcoin is still mined by ASIC miners. If with Bitcoin mining everything is stable and predictable in terms of equipment selection, because ASIC manufacturers of SHA-256 miners have not made revolutions for a long time and each new generation of ASICs is slightly better than the other. Then the situation with mining on video cards is constantly changing, tk. over the past year, AMD and Nvidia's next-generation video cards have gone on sale, which can offer much more energy efficiency than video cards released just a year ago. In addition, one can observe an increasingly strong division of miners into two castes. Those who can mine ethereum on their equipment and those who do not. And this "divide" is at the border of 5Gb video memory, tk. for mining Ethereum at the beginning of 2021, you need exactly that much video memory.

What does a computer do when mining cryptocurrencies in simple words

The concept of cryptocurrency mining is familiar to many firsthand, because all experienced PC users have probably tried to run the program for mining. The fact that cryptocurrency is mined with the help of mining and you can make money on it is also familiar to many. But what exactly does a computer or asic (a specialized device for mining) do during mining, why go through some hashes, i.e. the technical side of the issue is already familiar to a narrower circle of users. Because of this, many "conspiracy theories" have arisen on the network, such as that Bitcoin is someone's project to seize huge computing power to hack the Pentagon or other similar organizations. That the computer powers of cryptocurrencies are used for secret scientific research, communication with alien intelligence, and that the cryptocurrencies themselves were invented as a cover for all these "dark deeds". Next, we will try to highlight the bitcoin mining process in the most understandable way and what tasks your computer solves at this time, so that you can more accurately represent the technical part of the mining process, and you looked at all the "conspiracy theories" as not a very good joke.

Income from mining on video cards. Factors affecting the payback of equipment.

When a cryptocurrency once again hits new records in its value, the excitement around cryptocurrencies is observed not only on crypto-exchanges, but also in computer stores, where video cards, power supplies and other elements necessary to create a mining rig on video cards are bought for a clean one. Such an increased demand for video cards is due to the high profitability of mining and the rapid payback of equipment. When a person who has not previously encountered mining sees on mining calculator sites the profitability figures of 300% per year or even more, then, not knowing the many nuances of how such calculations are made, he can make a big mistake by buying equipment at an inflated price in the hope of a payback at 3 months, which are drawn to him by various mining calculators. Further in this article, you will learn about all the factors that affect the income from mining on video cards and how they can affect the payback of mining equipment in the future.

Hive Os: GPU overclocking

In addition to purchasing new video cards (which is now quite problematic, given that there are no video cards in stores that are slightly better than budget ones and prices that are up to 2 times higher), overclocking video cards is an excellent way to increase mining income. In this article, we will talk about how to overclock Nvidia and AMD video cards using the most popular operating system for miners based on Linux - Hive OS. To overclock the GPU in Hive OS, there are so-called "overclocking profiles" and thanks to the correctly selected parameters of overclocking and undervolting the GPU, you can significantly increase the hash rate of your rigs, as well as reduce their power consumption, which in turn will allow you to increase the mining efficiency and install even more video cards if you are suddenly limited by wiring, as well as reduce the temperature of the equipment.

Mining Ether (Ethereum, ETH) in 2021

At the turn of 2020 - 2021, we once again observe an increased interest in cryptocurrencies from investors and miners, which is why the cost of cryptocurrencies breaks new records, and the profitability of mining cryptocurrencies also brings in excess of income to owners of ASICs and mining rigs on video cards. The most profitable cryptocurrency for GPU mining will remain Ethereum (Ethereum), or Ether for short. On exchanges, Ether can be found by the ticker ETH. If you have just started to get involved in cryptocurrency mining or have left mining for a long time and decided to refresh your knowledge in this matter, then our further guide on mining ether on video cards will be just for you.
