0.21.6 (Windows): Mining EthashLowMem@prohashing.com not working #582

Closed UselessGuru closed 3 years ago

Command line used:

t-rex.exe --algo ethash --url stratum2+tcp://eu.prohashing.com:3358 --user #################### --pass a=Ethash-LowMemory,n=########,o=############,l=1 --no-strict-ssl --no-watchdog --api-bind-http 127.0.0.1:4003 --api-bind-telnet 0 --api-read-only --gpu-report-interval 5 --quiet --retry-pause 1 --timeout 50000 --devices 0

There seems to be a problem with parsing the password field or the pool does not understand it.

Why do you think there's a problem with password parsing? The error is GPU #0: not enough free memory to mine ethash at epoch 270

UselessGuru commented 3 years ago

Why do you think there's a problem with password parsing?

Because the pool reads the password data to determine the max available VRAM (parameter l=[VRAM GB] and then selects a coin with a DAG that should fit in memory. https://prohashing.com/tools/miner-configurator/Ethash-LowMemory

Other miners work fine, e.g. phoenix or gminer

I don't have an account on prohashing so can't really try it myself, but maybe use stratum rather than stratum2?

That made a difference - thank you. ProHashing requires stratum for EthashLowMem, stratum2 however is OK for normal Ethash.
