When it comes to how to mine with a graphics card, it can be said to be a question that every early miner wants to know. But before that, the editor of the currency circle thinks that everyone should first understand the situation of graphics card mining. Graphics card mining simply means using your For graphics cards, you work for others in your spare time in exchange for rewards. Only AMD graphics cards are suitable. After understanding graphics card mining, let’s get back to the topic. How does a graphics card mine? Below, the editor of Coin Circle has compiled a graphics card mining tutorial for investors to learn from.

## How to mine with graphics card?

Preparation:

1. Graphics card:

A card: Sapphire 470d, Sapphire 470, Sapphire 480, 4G and above video memory.

N card: 1060, 1070, 1080 and above.

2. Motherboard:

There is less demand for graphics card mining bandwidth, and PCI-E 1X on the motherboard can meet the bandwidth requirements.

Generally, the motherboard has 3-5 PCI-E 1X interfaces and 1 PCI-E 16X interface. In addition, the motherboard has a large 4PIN power supply interface, which improves stability to a certain extent. PCI-E
1X requires purchasing a 1X to 16X extension cable.

In addition, the graphics card needs to install the driver and opencl sdk, because many mining programs are implemented based on opencl. How to install drivers and opencl on windows and ubuntu, you can Baidu or Google.

Here, we mainly use mining ether as an example to explain.

First you need to apply for an Ethereum (ETH) wallet. You can use imtoken's Ether wallet or the exchange's wallet address.

Then download a mining software. There are two types of mining software: single mining and dual mining. Single mining refers to mining only one currency, ETH. Double mining refers to mining ETH and another currency together. It will not affect the single mining of ETH. Computing power, but dual mining consumes a lot of power, and can make the machine temperature too high, which can easily lead to problems such as burning the power supply or circuits, so choose carefully.

3. Select a mining pool:

Open the mining pool website address and enter the Ethereum wallet address bound to you. You can view the mining machines you have connected to the mining pool and the current computing power. If you see your mining machine and normal computing power, mining can start.

2. Prepare for mining

Next, I will tell you how to operate it after you have a graphics card.

1. Install the graphics card into your case or professional mining machine.

2. Choose mining software. There are many mining software, such as: mieros and Spark OS that use U disk as the system. And mining software running on W10 Easy Miner, Open Source Miner, etc.

3. Register for an exchange or ETH wallet to obtain a revenue address. This address is used to store the mined ETH. (It is recommended that you use the exchange address directly. The advantage of this is that you can directly buy and sell money. The exchange recommends that you use the three major exchanges, OK and OK)

4. Debug the mining machine to run normally and mine ETH.

## What exactly is the principle of graphics card mining?

To put it simply, mining is to use a chip to perform a calculation related to random numbers, and then obtain the answer in exchange for a virtual currency. Virtual currencies can be exchanged for currencies of various countries through certain channels. The chip with stronger computing power can find this random answer faster, and theoretically can produce more virtual coins per unit of time. Since it involves random numbers, you can only get rewards if you happen to find the answer.

Satoshi Nakamoto elaborated in his paper: "Without the existence of a central authority, miners are encouraged to support the Bitcoin network, and the Bitcoin currency circulation system also has an initial source of currency injection."

Satoshi Nakamoto compared the consumption of CPU power and time to generate Bitcoin to a gold mine consuming resources to inject gold into the economy. Bitcoin's mining and node software mainly initiates zero-knowledge proofs and verifies transactions through peer-to-peer networks, digital signatures, and interactive proof systems.

Each network node broadcasts transactions to the network. After these broadcast transactions are verified by miners (computers on the network), miners can use their own proof of work results to express confirmation. The confirmed transactions will be packaged into data blocks. , data blocks are strung together to form a continuous chain of data blocks.

Satoshi Nakamoto himself designed the first version of the Bitcoin mining program, which was later developed into the widely used first-generation mining software Bitcoin. This generation of software was popular from 2009 to mid-2010.

Each Bitcoin node collects all unconfirmed transactions and aggregates them into a data block. The miner node appends a random adjustment number and calculates the SHA-256 hash value of the previous data block. The mining node keeps trying again and again until it finds a random tweak that produces a hash value below a certain target.

The above is an introduction to how graphics cards mine. The editor of Coin Circle would like to remind investors that when buying graphics cards, they must be cautious to avoid encountering problems by flashing the BIOS.
Tampering with graphics card information. As we all know, the most important component of a graphics card mining machine is the graphics card. The performance and quantity of the graphics card directly determines the computing power of the mining machine. Some unscrupulous graphics card mining machine dealers will tamper with the graphics card by flashing firmware. Information, thereby selling low-end graphics card mining machines for the price of high-end mining machines.
