How to Overclock Antminer Z11 to increase its profitability

Overclock Antminer Z11

To Overclock Antminer Z11 you need to increase the operating frequency of your Miner. If increasing frequency is not possible then install a custom firmware on your Miner.

What is Overclocking?

Overclocking is the process of speeding up or increasing the clock speed than official efficiency provided by Manufacturer. In other words, overclocking is the method of configuring the hardware components to obtain extra utility and performance than the default. We have to take many precautions while overclocking any device.

Benefits of Overclocking

Overclocking is done to increase the efficiency and performance of CPU and GPU.

Demerits of Overclocking

The definition of overclocking itself defines that it is an additional requirement from the CPU and GPU than provided from the manufacturer. The process is very risky and the result could be losing the device.

Why overclocking is very dangerous?

Overclocking is a very heavy process which triggers main processor or graphics controller where systems such as RAM are also involved. This process goes very heavy resulting in more power consumption, fan noise and increases th amount of heat produced by your ASIC miners. ASIC miners are very efficient but they lack in cooling, mining with ASIC miner requires more power due to this heat increases. After overclocking it may not be possible for Antminer to handle that amount of heat and may result in losing your device.

Precautions –

Increase the PSU.
Use External Fans or AC to cool your device while mining.
Increase limited Frequency.

But still, if you have decided to test this process on your own risk then let’s get started with the process of overclocking Antminer X3 220kh and increase its profitability.

Instructions to overclock Antminer

This process is successfully tested on Antminer T9 and S9 but We have not tested this process on Antminer Z11.

  1. First of all login to your SSH.
  2. Use your IP address in your browser in my case IP address is So, use the Antminers IP address in your browser.
  3. On login prompt  Username: root and Password: root
  4. After a successful login, you will be sent to Antminer’s Dashboard.
  5. Select Miner configuration > Advanced settings.
  6. Note the frequency configured by the manufacturer.
  7. Next step is to access the Miner Status tab.
  8. Now note down the hash power obtained by the device.
  9. You should record the temperature of your Asicminer as a precaution.
  10. Perform benchmarking to create a perfect hash rate for your device.
  11. The process of benchmarking includes testing temperature, stability and power consumption of the device.
  12. However, you can go back and see your increased hash power in Miner status tab.
  13. Congrats, Enjoy more mining rewards.
