How to know the hash rate of a video card for mining

1 miesiąc ago 0 42

Different methods of cryptocurrency mining have an indicator that determines the performance of the equipment. It is necessary to understand how much profit to expect and whether the efforts of the miner will pay off. How to know the hash rate of a video card for mining, what affects it and whether it can be increased – key points in cryptocurrency mining. From the ability to choose the right equipment in terms of performance depends on how quickly it will solve cryptographic tasks. Each unit of value shows how many calculations a miner will make in a period of time.

What is the hash rate measured in

To determine performance, the number of operations (hashes) in 1 second is taken as a benchmark. As in other metrics, there are designations and abbreviations. The extraction speed of different equipment can differ by dozens of times, so the indicator is encrypted according to the scheme in the table.

Volume name	Brief designation	How many units contains
Kilo	KH/s	1000
Mega	MH/s	1 million
Giga	GH/s	1 billion
Tera	TH/s	1 trillion
Peta	PH/s	1 quadrillion
Exa	EH/s	1 quintillion
Zetta	ZH/s	1 sextillion

What affects hash rate

Hash Rate is the sum of the performance of the hardware that a user connects to the network. Factors that increase or decrease this rate:

The number of devices. The more of them there are, and the characteristics of the power are higher, the more productive the mining.
Algorithm. Each network has its own complexity of solving tasks, after which the user receives a reward. Connecting new miners increases the requirements for equipment: mining cryptocurrency becomes more difficult. For one video card when connected to different networks, the performance will be different.
Timings. This is the period from sending a command to an operation to its execution. By default they are set not in favor of performance. You can change the setting through re-flashing – this will reduce the time to deliver the command.
Temperature. When the equipment heats up, the indicator decreases. Standard coolers are not always designed for cooling in the conditions of mining. It is worth equipping the farm with an additional system.

How to check the hash rate of a video card

For already purchased equipment, the indicator is specified in the program of the miner. Even easier – type the name of the card into a search engine. This way you can understand to what level the device is overclocked. Another way to check the hash rate of a video card online is to use a mining calculator. In it, you select the model and enter the cost per kilowatt per hour.

What level is considered good

Security in mining depends in part on the complexity of the blockchain. The more miners connected to it, the more performance is needed to produce cryptocurrency. To hack the system, you need to provide more than 51% of its capacity, and on large projects, this is almost impossible to accomplish.

High power of the network requires from miners the appropriate equipment, otherwise the activity will be unprofitable. To mine a block on an inexpensive and relatively weak device, choose systems with a moderate hash rate, which shows an increase. In this case, competition in the network is less than, for example, Bitcoin, and the chances of getting cryptocurrency are greater.

Good computing power is the level of the indicator at which in the network on a certain video card, the profit justifies the cost of electricity. You can calculate the statistics with the help of online calculators. These are services in which the user needs to enter the model of the device, the cost per kilowatt per hour and choose a blockchain.

How to find out the hashrate of a laptop

Such devices have long been not considered a good choice for mining, but are still suitable if there is no possibility to staff a farm or purchase an ASIC. However, for mining coins do not use office laptops – you need a gaming version.

A powerful graphics card is required. How profitable or unprofitable will be such mining – will help to know the calculator, but for this you need to understand what characteristics the device has.

To calculate the hash rate of a video card, you need to know its model. This information is available on the manufacturer’s website and on the laptop itself.

Here is an example of calculating the profitability of mining on a DELL G5 15 5500. It has an RTX 2060 card. If you find it in the table, then the indicators in different networks will be as follows:

Ethash – 31 Mh/s.
Zhash – 57 h/s.
Octopus – 34 Mh/s.
ProgPov – 18 Mh/s.

At an electricity consumption of 0.08 $/kWh. (5 rubles), for example, this will allow mining Ethereum for $0.46 per day of net income. Excluding electricity, it will be $0.69. The most profitable, according to the calculator calculations, is to mine Conflux (in the Octopus network). This will bring the user $0.58 per day.

How to increase the hashing level

Buyers have a conflict of interest with manufacturers: the former want the equipment to work at full capacity, the latter do not like to fix under warranty. Video cards are sold with certain limitations to serve users for a long time without breakdowns and failures.

To use the full power of the device it is overclocked – change the factory settings by reflashing. The hash rate increases, but the card begins to heat up more, so you will need additional cooling. Otherwise, there will be little point in overclocking – when overheating, the index decreases.

Summary

The hash rate tells you about performance – how many operations per second a video card performs when mining a certain coin. It is important to know it in order to calculate the profitability of cryptocurrency mining. You can see the processing power in the miner program or in an online calculator, specifying the card model and blockchain. For each network, the indicator of one card will be different – it depends on the complexity of blockchain computation. The more participants are connected to the blockchain, the more serious equipment will be needed to mine cryptocurrency. Profitability is also checked through a mining calculator – enter the name, and the service shows how much money can be earned, taking into account electricity consumption.

Frequently Asked Questions

📼 If I have 10 video cards, how do I calculate their total hash rate?

Find out and record the rate of each of them when running on the right network, then add it up.

🔥 How does overheating affect hash rate?

When the temperature rises above 75°C, the performance starts to drop, and already at 90°C it is better to unplug the equipment and check the cooling system.

💻 What is a stress test?

The equipment is subjected to a load – this allows you to find out how stable and reliable the video card is in operation.

❓ What happens if I use different brands of devices in my farm?

Each farm needs its own software. Components from different manufacturers can cause malfunctions in the operation of the miner.

👨‍🌾 What components will I need for my farm?

For a basic build – about 15 items. You need a processor, motherboard, RAM, power supply and more. Learn more in this article.
