Hello guys,

I'm fairly new to the whole mining topic (yeah, I missed the train and stuff like that but I started mostly because of interest. I do it on my PC ;-) ).

I got the Claymore Dual Miner Up and Running with my Eth Wallet and everything seems to be fine.

So now I wondered about the Dual Mining feature.
I struggle setting this up. What I did:

• Created a wallet at https://wallet.decred.org
• Got a decred wallet address
• Searched for a decred pool
• Modified the start batch file for Claymore Miner

So the batch now looks like this:

Claymore starts up with
ETH: Authorized
Setting DAG epoch #xx...
DCR: Stratum connecting to ...
DCR: Stratum - Connected
DCR: Authorization failed
: (null)

Can someone help me to clarify what this means? All shares from DCR will be rejected.

Thanks in advance,
Zuop

Read here http://www.decredpool.org/index.php?page=gettingstarted how decredpool works. You need to create a worker. Use stratum+tcp://yiimp.ccminer.org:3252 if you want to mine directly with your wallet as user and without going trough the hassle of signing up.

Sounds like you have your Decred pool account information wrong. In the config.txt you need to add the pool and login info like this:


Then in the epools.txt and dpools.txt you can specify any failover pools.

Thank you for the information. I was not aware I need to create a decred Account + Worker (I was using the web decred https://wallet.decred.org).
Also pointing out to use the config file was helpful, as i wrote a .bat file with the commands and probably would have not used a password as for the eth pool I use "x".

I have a few further questions:

• Is stratum+tcp://stratum.decredpool.org:3333 the right pool for Claymore Miner? On the website there's only info about ccminer and Nicehash & sgminer.
• MyName.MyWorker is the wallet so if I would like to change decred to anything else I can do it with MyWorker + pw?
• In the config file -mode needs to be 0 for dual mode does it?
• In the epools.txt a sample uses ALLPOOLS: 1, what does this mean?

Thank you again, you helped me already,
Zuop

I recommend using the epools.txt and dpools.txt so that you can setup failover pools.

For Claymore's miner you should use:


The other stratum port 3333 is for the Nicehash and sgminer and will give you rejected shares. The worker account setting depends on the pool you use. Some pools like Dwarfpool,  you use your wallet address and any password. Other pools like decredpool.org, you need to register an account on the pool and create individual workers and passwords in your account that you then setup in the miner command line or configuration file. Yes, for dual mining mode with Claymore's miner you set -mode 0 (which is also the default if not specified). The allpools settings allows the miner to use the default pools for the dev fee. You only need to set it if the pool you are mining at does not have an account for the dev fee. All the configuration options are in the Readme file.

Hi again,

thanks for the advice.

Everything was running for a complete day, but now after I modified the epools & dpools files I have a 100% rejection rate for DCR shares although at the beginning it says DCR Authorized.
I can't find anything on this on the internet, can you think of anything I could do? Even when I restore the original pools file all shares rejected.

Thank you very much,
Zuop

Make sure you're using the newest Claymore miner

I have the latest Claymore Miner (v9.3) and as mentioned it already worked.. somehow, without any obvious reason, it does not work for DCR on my machine anymore  ???

Just reinstall the drivers.

Crazy. To close the topic:

I didn't reinstall the graphic driver like supposed (maybe this would have been an option in the next days).
I change the server back to stratum+tcp://stratum.decredpool.org:3343 and created a new worker on decredpool, now it works again? That's crazy because changing the server back to 3343 was one of the first things I tried after it broke..

Nevermind, I got the help I asked for, thanks guys for helping a beginner! Really appreciate it.

Cheers Zuop

Hello! I've also missed the train in this matter, but I recently got informed very well about this (https://cryptoorders.com/articles/complete-guide-bitcoin-mining/). I hope that was useful to you!

Asic start mining DCR thus the difficulty went up.
So, everybody ( but not you   till now) decide to stop spending energy to Dual mine DCR because you are spendinge more than what you gain
So, pools recognize you haven't an ASIC e reject your connection
Most of the people is now mining XVG with the 11.x Claymore dual miner

Is mining pools for Decred on http://yiimp.ccminer.org/ is still working ?

I am traing on my Claymore’s dual ethereum miner v15 with no luck :/


Thx for any infos.

Read the post above yours about dual mining decred.  also:  https://bitcointalk.org/index.php?topic=2162413.0

I don't understand why they put in readme.txt information about not working from 2018 mining pool.... This is gravy train :/
XVG is hopeless also.

Thx for your remarks, man.

Well Claymore miner has been around for about 6 years now.  And it hasn't been updated since 2019.  A lot of time those readme files initially get made, and then stuff (like new features) get added to them, but obsolete information stays.  Those pools listed in the readme are just examples, made to show you the correct syntax, not necessarily to recommend a pool.

If you want to dual mine, I think the only option at this point is Zilliqua.  Check this out for more info:  https://cryptomining-blog.com/12610-get-even-better-profit-by-dual-mining-ethereum-eth-and-zilliqa-zil/

Thx for the advice.. I have started mine in dual mode with Zilliqua.
