Why Does Antminer Z15 Rejection Rate Get High?


In this guide, we will explore the reasons behind the high rejection rate of Antminer Z15 and discuss potential solutions for improving mining performance.

Cryptocurrency mining has become increasingly popular over the years, with many individuals and organizations investing in specialized mining hardware like the Antminer Z15. Designed specifically for mining the Equihash algorithm, the Antminer Z15 has gained significant attention due to its high hash rate and efficiency. However, like any mining hardware, it is not immune to challenges. One such issue faced by miners is the high rejection rate experienced with the Antminer Z15. First, let’s understand what mining pool rejection rate is.

What is Mining Pool Rejection Rate?

The rejection rate of the mining pool refers to the ratio of the data rejected by the mining pool to the total number of sent data when the mining machine sends data to the mining pool.

If the hashrate of the miner is not affected, this parameter can be ignored.

According to different algorithms and hashrate, the miner sends data to the mining pool every few seconds or ten seconds. This data has certain requirements. When the submitted data is abnormal and does not meet the requirements of the mining pool, the mining pool will reject the data, and the rejection rate of miners will increase.

Reasons of Antminer Z15 Rejection Rate Get High?

High miner rejection rate may be resulting from the following reasons:

Poor Network and Slow Speed

Miner connects to a mining pool. And mining pool regularly distributes jobs to miners; then, the miner submits shares to a mining pool, which involves a large amount of data transmission. Therefore, network performance directly impacts the hash rate and rejection rate of miners.

You can confirm network status by the following steps:

1) Connect your computer to the network where the miner is connected.

2) Open the cmd command prompt on your computer.

3) Enter ping + space + mining address of a particular currency in a mining pool.

Miner Temperature is Too High

The high temperature of miners will also affect the hash rate and rejection rate, especially in hot summer. The temperature in the screenshot below is normal. Different miners have different rated temperatures, and it is usually normal for temperatures below 90-100. Please refer to the rated temperature for different miners.

Firmware Issues

Due to firmware issues, some miners may usually have a high rejection rate. It is recommended to try again after upgrading to the latest Antminer Z15 firmware.
