ethash difficulty stuck at 1.07

Post by UbjfP2ZOJa » Tue May 10, 2022 8:20 pm

I'm stuck. Same symptom using both t-rex and gminer: difficulty never changes from 1.07. Started a couple days ago.

t-rex.exe -a ethash -o stratum+tcp://prohashing.com:3339 -u myusername -p n=myrig,o=mygroup,l=6.8,e=off --coin eth --dag-build-mode 2 --send-stales --lhr-autotune-mode full --pl 54 --cclock -500 --mclock 1315

RTX 3070, Nvidia version 512.15; gminer 2.80, t-rex 25.12 and 25.15; Windows 11

I don't use any other pools, but gminer and t-rex 25.12 both worked before the changes in the last few days. Any ideas?

Our implementation of ethash mining turned out to be incorrect. It isn't possible with currently implemented workers to have different difficulties assigned to any miner at the same pool.

Since yesterday, we did more research and released a corrected version of the mining servers. Ethash, RandomX, Etchash, and Ethash-LowMemory will never be able to have a different difficulty between workers, although we may increase that static difficulty as hardware becomes more powerful.

We apologize for the inconvienence!
