In my GPU miner machines, there’s one or two GPU card that are not working / showing 0 hashrate. Why?

This issue, which is commonly seen in ETH mining, may be caused by lacking virtual memory, not enough voltage, or miner system issues.

  1. Swap sequences of different GPU cards, start your mining software again and check if it is caused by one or two single cards. If so, it means something is wrong with your GPU cards.
  2. If it is not, please try to increase your virtual memory, institute or increase the power and see whether it works.
  3. If it is still not works, please install the original Win10 system and try again.
