Decred (DCR) Mining on Nvidia with Getwork Over Stratum

17 Feb


Tpruvot, one of the ccMiner developers has released a test version of his fork with Decred (DCR) support with getwork over the stratum protocol (source) along with the needed support for yiimp (source), his fork of the yaamp multipool software. We have compiled a Windows binary from the test version with Decred support and getwork over the stratum and have tested it on to see how well it is performing. The result was just as you would expect from any good mining pool with stratum support – no stale shares and properly working difficulty adjustment. This version also comes with the regular getwork support, so it will work with the regular Decred mining pools as well. You are welcomed to try mining Decred on the Yiimp pool with the test version of ccMiner 1.7.3 form tpruvot, the Windows binary below is a 32-bit one, compiled with VS2013 and CUDA 6.5 and it should be compatible with older Compute 2.0 or later Nvidia GPUs plus a 64-bit one with CUDA 7.5 for Compute 3.5 and newer GPUs.

Update: The Decred (DCR) mining pool at Suprnova ( now also has a stratum enabled port that will work with this miner, so you can test it there as well if you are mining Decred with Nvidia GPUs. Download again for the latest updates that should help resove issues people are having with stratum on Suprnova.

Thanks again! I was waiting for stratum support and a nice dedicated nVidia miner for Decred. This works very nicely for me.

the application is unable to start on 64bits systems?

The binary is 32-bit, but it should also run just fine on 64-bit systems…

it crashes on my system, 0xc000007b, maybe it’s the .bat?
ccminer.exe -a decred -o stratum+tcp:// -u username.worker -p password?

sorry for being a lame, my bad, forget to replace the NEW msvcr120.dll

The old one doesn’t work!

Can we get a CUDA 7.5 with 64bits support? That would be awesome.

The archive now includes 32-bit version with CUDA 6.5 and 64-bit one compiled with CUDA 7.5.
