All About BTC, LTC, ETH mining as well as other alternative crypto currencies
The Siamining mining pool for SiaCoin (SC) that we have already covered a couple of times has something new and interesting for the people mining SIA. They have released a new Stratum-only OpenCL GPU miner for their mining pool that is designed to be fast, lightweight and easy to use. Do note the miner is supporting only SiaMining’s Stratum protocol implementation as there are a few different Stratum approaches, so the miner will not work with other pools unless they have implemented the same Stratum support. We have tried the Marlin miner and it seems to work pretty well, delivering what the devs promise indeed.
What we don’t like about it however is that there is no source code published on their GitHub and only a 32-bit Windows binary and 64-bit are available for users to download. Since there is no source you cannot compile the miner yourself and that may be a limiting factor for some users. Do note that even though the miner is OpenCL one you can also use it on Nvidia GPUs as well as on AMD, unfortunately tpruvot’s ccMiner fork does not yet support the Stratum protocol used by SiaMining. So if you are Ok with downloading binary releases, you can do so and try the Marlin miner yourself… that is if you are mining SiaCoin on the SiaMining pool or are planning to check it out.
Tpruvot has made an official release of his updated ccMiner fork (source) version 1.8.1 along with Windows x86 and x64 binaries available for download. The x86 Windows binary is compiled with VS2013 and CUDA 8.0 RC and the x64 binary is compiled with CUDA 7.5, it is best to use the latest video drivers to have support for CUDA 8.0.
The new ccMiner 1.8.1 adds support for mining Siacoin (SC) on Nvidia GPUs using CUDA, SIA uses Blake2-B algorithm, though at the moment different pools still seem to rely on different protocols for mining and not all of them are yet supported by ccMiner. The miner supports the SIA Nanopool RPC (getwork over http) as well as the getwork over Stratum implementation of Suprnova, but not yet the Siaminingpool stratum protocol (you should still be able to mine there via getwork). The hashrate seems to be slightly better than that Sia Go Miner that uses OpenCL and also works on Nvidia GPUs.
The new version 1.8.1 also comes with small improvement in the LBRY hashrate improvements (by alexis78) over the previous release 1.8 that introduced Library Credits mining. So if you are mining LBC with Nvidia GPUs, then you might wan to update to the new release in order to get slightly better hashrate. The Lyra2RE support has also been updated with the with the Nanashi Meiyo-Meijin improvements, so it should be faster than before.
The Siamining mining pool for Siacoin (SC) we have written about recently has also added Stratum support. Their Stratum implementation however is a bit different from the one that Suprnova has introduced a few days ago for their mining pool and thus requires users to use a different version of sgminer. While the Suprnova Stratum implementation is more of a getwork over Stratum and based on our tests it does perform very well, Siamining is claiming that their solution in true a Stratum support, so in theory it should result in slightly better efficiency. Of course the Siamining mining pool does still support the regular Siacoin Go pool miner that also produces very low percentage of stale shares, though with Stratum support the results should be even better now.
Below you can download a 32-bit Windows binary of the sgminer 5.4.0 fork for Siamining with Stratum support (source). Do note that this miner will currently only work with the Stratum Mining Protocol for Sia implemented by Siamining. The miner works on both AMD and Nvidia GPUs, so you should be covered regardless of the GPUs you have available, though it uses OpenCL for both. Our initial tests are showing really good results in terms of efficiency and lack of stale shares, so it seems that things are already working pretty well with this Stratum implementation for Siacoin (SC) pool mining at Siamining. As a result now you have even more alternatives for pool mining Siacoin to try and choose from…
