low hashrate ETC nvidia p104
Hello,
I have very low hashrate when mining ETC with nvidia p104 gpu, Driver Version: 450.51.06    CUDA Version: 11.0.
When mining ETC: ./nanominer config_etc.ini, output: 3.712 MH/s power 70.97W
When mining ETH: ./nanominer config.ini, output: 34.773 MH/s power 156.41W
What can cause this problem?
Thank you.
