Tests done in early May by the MinerMore sysop showed that t-rex performed the best, followed somewhat closely by kawpowminer.
After you have added your new miner software, you can update your cmd/bat/script file to instruct it to use the new connection. The connection line looks something like (note that the following lines contain testnet ports):
kawpowminer -U -P stratum+tcp://[email protected]:4505
or...
t-rex -a kawpow -o stratum+tcp://rvnt.minermore.com:4505 -u username.worker -p x
or...
gminer --algo kawpow --server rvnt.minermore.com:4505 --user username.worker
or...
nbminer -a kawpow -o stratum+tcp://rvnt.minermore.com:4505 -u username.worker
or...
TT-Miner -coin rvn -P stratum+tcp://[email protected]:4505
IMPORTANT NOTE: The connect lines shown above only work currently for testnet. Once we fork on May 6th you will need to be using port 4501 and a real valid Ravencoin address (or MinerMore username) for mining. For more information on setting up for May 6th, see this page.
If you are using t-rex, you can use their fork-at feature to automate the transition to the new algorithm. Update your cmd/bat/script file to instruct it to automatically switch at the right time.
For example, if your launch line looks like:
t-rex -a x16rv2 -o stratum+tcp://us.rvn.minermore.com:4501 -u username.worker -p x
Then you will change it to:
t-rex -a x16rv2 --fork-at kawpow=2020-05-06T18:00:00 -o stratum+tcp://us.rvn.minermore.com:4501 -u username.worker -p x
Then restart your miner and it should take care of everything for you at that point.
