Ethereum: cgminer Rejected as low difficulty

Ethereum cgminer rejection: common problem and possible solutions

As a cryptocurrency enthusiast, you are not the only one facing rejection issues when using Ethereum cgminer. Cgminer is a popular mining software used to mine Ether (ETH) on various platforms, including Bitmain’s Antminer. However, when it comes to mining Ethereum, one of the most frustrating experiences is getting rejected by cgminer.

What causes cgminer to reject?

The cgminer rejection problem can be caused by several factors. Some common reasons:

• Low difficulty: When the difficulty level of the Ethereum Proof-of-Work (PoW) consensus algorithm drops, it becomes difficult for miners to confirm transactions and create new blocks. This reduced weight means that fewer Ethash hashes are produced, resulting in cgminer rejection.

• Hashrate Imbalance: If your mining system’s hashrate is not balanced across multiple GPUs or ASICs, this can cause bounce issues when trying to mine ETH with cgminer.

• Power consumption and cooling issues: Poor power management and inadequate cooling systems for your mining rig can cause it to overheat, resulting in cgminer attempts being rejected.

Troubleshooting: Minor Difficulty

In order to solve the problem of low difficulty, it is necessary to adjust the level of difficulty in Ethereum’s Proof-of-Work consensus algorithm. Here are some things you can do:

• Check Ethereum Fork Settings: Make sure your Ethereum mining software is set up with the latest version of the blockchain fork (eg 2016 or later).

• Adjust the difficulty setting: Try increasing the difficulty level to see if that fixes the problem.

• Update cgminer configuration files: Sometimes outdated or corrupted cgminer configuration files can cause rejection issues. Try updating the files to the latest version.

Additional troubleshooting steps

In addition to adjusting the weight settings and updating the cgminer configuration files, here are some other steps you can take:

• Monitor the temperature and power consumption of your mining rig: Make sure your rig is running at optimal temperatures and has enough power to handle the workload.

• Check for overheating issues: If your mining rig is generating excessive heat, it could be causing a bounce problem. Adjust or replace cooling systems as needed.

• Update your mining software and drivers: Make sure your mining software and drivers are up to date as outdated versions can cause compatibility issues with cgminer.

Conclusion

Ethereum cgminer crashing can be frustrating, but by identifying the root cause of the problem and taking corrective action, you can resolve the issue. By adjusting the weight settings, updating configuration files, monitoring equipment performance, and resolving overheating issues, you should be able to get your mining rig up and running smoothly again.
