What does miner overclocking mean?

As the name implies, miner overclocking works beyond the rated frequency, but huge security risks increase the hash rate and revenue. For example, many miners were infected with viruses due to downloading overclocking firmware, causing tens of thousands of miners in the mining farm to be infected simultaneously, with daily losses ranging from 1,000 to 10,000 US dollars.

Miner overclocking is actually a double-edged sword. Although it has drawbacks, it can also bring higher output. So what is a virus? This article will take you to understand everything related to miner viruses to deal with viruses.

Types of overclocking miners

In theory, as long as the miners who can adjust the frequency can overclock, the miners of big brands can overclock. The Antminer can overclock through the official overclocking firmware. Ebit can change the frequency directly from backstage, and other brands can download their firmware for overclocking.

Will overclocking affect the life of miners?

Will affect. Because the rated hash rate and power consumption set at the factory are tested, and there are technical standards, overclocking is equivalent to overloading, the temperature will rise, the noise will be more significant, and the long-term will affect the hash board and chip life, so overclocked models should pay special attention to the temperature and ventilation and heat dissipation of the miners.

Manifestations and characteristics of miner poisoning

Common manifestations of miner poisoning are reduced hash rate, no hash rate, inability to enter the miner's backstage, the mining pool's address has been modified, and the inability to upgrade the firmware from the miner's backend, etc. These are relatively easy to find. However, some viruses only tamper with the mining pool address in the early morning hours and restore the original settings after a few hours, which is very difficult to detect. Therefore, it is recommended that each miner regularly check backstage or check the daily income of the mining pool.

Why a miner poisoned can infect the entire mining farm

The miner virus spreads through the network, and the miners of the same mining farm are in the same local area network. The virus can be directly copied to all miner systems through the router quickly.

Antivirus operation method

The previous virus is relatively simple, which can be understood as a program to modify the mining pool installed in the miner system. The virus can be cleared by resetting the miner. But the current virus is very abnormal and stubborn. Some of the miner’s system files have been modified. Reset does not affect it. You must manually swipe the card to clear the virus. It also requires network isolation and observation for a while. The router must also Restore the factory settings. Even the computers used in the same local area network have to redo the system.

Is antivirus helpful software?

Due to the immature technology, there is almost no software on the market that can altogether remove the virus. Therefore, it is recommended that each miner swiped and network quarantined to ensure complete protection against the virus.

How to prevent miner poisoning?

First, ensure that the network environment of the mining farm is safe and non-toxic.

If it is a brand new miner, change the backstage login password when put on the shelf.

If it is a used miner, it is recommended to swipe the card for all miners and then observe the network isolation for a while.

Source of miner virus

Download unofficial or unknown third-party miner firmware, overclocking firmware, miner management software, etc.

Other miners or equipment in the mining farm carry viruses.

Network isolation steps

First, check all computers and miners in the local area network to ensure they are not infected with viruses, and isolate the poisoned miners from other miners on the network. Then, use secondary routing to isolate:

1) Divided into three areas: poisoned miner, recovery observation, and normal miner area.

2) The router does not need to add any route pointing to other routers; that is, the default settings are used.

3) The mainline from the primary route is connected to the WLAN port of the secondary route.

4) The switch is connected to the LAN port of the secondary router.

5) The miner's IP address is obtained on the secondary router.

The specific steps of the control board swiping

The so-called "card swipe" uses the SD card to force the original firmware to be written. First, prepare a card reader and a 16G SD card, download the control board recovery program of the corresponding model on the official miner website, and write the corresponding program into the card. Then use the SD card to restore the control board program. Different models have different methods. Take Ant T9+ as an example. You can refer to the article T9+ control board program recovery.

Summarize

Hash rate overclocking is prevalent and effective in increasing revenue, but choosing safe and reliable firmware is necessary. Do an excellent job in anti-virus-related work and regularly check the mining pool's income and the miners' temperature to protect their income and asset safety fully.
