A hardware error is an error that occurs when computing hardware performs calculations incorrectly. Such errors may be caused by unstable settings, overheating, power problems, faulty computing chips, or other component failures.

Causes of Hardware Errors

  • excessively high clock frequency;
  • excessively low voltage after undervolting;
  • excessive temperature;
  • unstable power supply;
  • physical failure of a computing chip;
  • memory or connection problems;
  • aggressive overclocking settings.

A small number of errors does not necessarily indicate complete equipment failure, but a persistent increase in their number may indicate an unstable operating mode. It is also important to distinguish hardware errors from errors related to the network or shares submitted to a mining pool.

Impact on Mining

Hardware errors can reduce actual performance, cause computational results to be rejected, or trigger restarts of individual components. Therefore, when configuring equipment, both the stated hashrate and the stability with which it is achieved should be evaluated.

If errors appear after increasing frequency, reducing voltage, or changing the power limit, the parameters are usually returned to a stable operating mode and then adjusted gradually while monitoring temperature and performance.
