Changelog [0.19.7]:

  • (ethash, octopus, kawpow) Improve stability for 30xx series GPUs
  • (ethash) Verify overclock stability after DAG rebuild (Instability detected message is printed in case there are issues)
  • Add --gpu-report-interval-s parameter to control hashrate summary report frequency based on the number of share submissions
  • (API) Add new pause command for control handler to pause and resume mining
  • (Watchdog) Display a list of GPUs caused miner restart with GPU is idle error

Bug fixes:

  • (x21s) incorrect size of extranonce2 error
  • (UI) Incorrect GPU index in share submission report when --pci-indexing mode is enabled
  • (API) Miner fails to switch algorithms on the fly for some "<algo_from> -> <algo_to>" combinations


Hello, I have a strange issue on a 3090.

The MH/s is slowing down very quickly, it start a 106 MH/S and go down litlle by little to nearly 50MH/s and then stabilize to that value. The GPU load is 100% but what is strange is the Core Mhz that is very low. I have another computer with a 3090 and it is always nearly 110Mh/s. it run both on windows 10 with the lastest Nvidia Studio driver. Is someone know what is the problem and is there a workaroung?
