New sgminer 5.1.0 fork with Yescrypt Support Available

2, May 2015

sgminer-5-1-0-yescrypt

You can now mine GlobalBoost-Y (BSTY) with AMD-based video cards thanks to a new fork of sgminer 5.1.0 from djm34 that adds support for Yescrypt (source) and we have compiled a windows binary that will allow you to try it out. The windows binary is compiled for x86, so it should work on wider range of systems using 32-bit or 64-bit Windows. Do note that Yescrypt GPU mining is still in early stage, so it might be a bit buggy initially and further optimizations in performance should be possible as this is a preliminary work to port the algorithm to GPU support. The coin does seem to handle well high intensity, so you should start low with 9 for example, also lower worker size such as 16 and 512 threads could be a good start. We are seeing a performance of about 700 hashes per second on a non-overclocked AMD Radeon R9 280X GPU with the settings above, but you are welcome to experiment. Do note that there is still more to be desired from the GPU miner as it is not faster than mining Yescrypt with an up to date CPU, for example a single Intel Core i7 5820K CPU achieves around 5.1 KHS mining GlobalBoost-Y (BSTY).

Update: There is now a slightly faster yescrypt kernel available that allows you to get some extra speed, we got to almost 800 Hashes per second with it, you can download the updated version from the link below. Also the latest version includes yescrypt-multi algorithm for Nvidia Maxwell GPUs (Compute 5.0 or newer) that may provide faster performance than the ccMiner release according to the author, though in our case ccMiner was still faster.

New ccMiner fork with WhirlpoolX Algorithm Support

27, Feb 2015

ccminer-whirlpoolx-djm34-dev-fee

There is now a Windows binary of a ccMiner fork available for mining Vanillacoin (VNL) that uses WhirlpoolX algorithm on Nvidia GPUs thanks to djm34. There is no source code released for the miner, only Windows binary that supports Compute 3.5 or newer Nvidia video cards. Do note that this version includes a 5% developer fee, so it will mine for the developer of the code to support his work! Also it seems that the miner only works on the two official VNL pools as well as the Suprnova Pool, it refuses to connect to to others. We are getting about 180 MHS on a stock GTX 980 GPU, though the author reports that is should reach up to about 200 MHS, probably with some overclock it will. You should expect about 60 MHS on a GTX 750 Ti GPU according to the author of the miner code. Recently there was a boom of interest in VNL even though it has not yet been added on an exchange, though C-Cex is apparently going to add it very soon, meanwhile MiningRigRentals and NiceHash have all added support for the new WhirlpoolX algorithm, so apparently the user interest continues to grow. If you are looking for a high performance AMD GPU miner, you can find the latest sgminer fork with WhirlpoolX support here, it offers similar performance to what the same class of Nvidia GPUs should provide using the ccMiner.

Performance Results from the ccMiner fork With NeoScrypt Support

1, Feb 2015

ccminer-neoscrypt-fork

Last month we’ve written about the Crowdfunding Campaign for ccMiner fork With NeoScrypt Support and the miner is already being made available for people that have donated to the developer djm34. We have already played a bit with the latest version of the ccMiner fork with NeoScrypt algorithm support and have tested it on multiple Nvidia-based video cards. Although we have tested the miner on Maxwell-based GPUs (Compute 5.x) only the size of the compiled Windows binary suggests that the miner is also compiled for Compute 3.x cards, so it should work on older video cards as well, though the performance may not be that good. Do note that the ccMiner fork with NeoScrypt support apparently does not currently have support for extranonce that is being used by services such as NiceHash.

We have used GTX 980, GTX 960 and GTX 750 Ti for our tests and the results you can find below are achieved with the latest video drivers that were released along with the GeForce GTX 960 video cards. We are seeing a considerable increase in performance when we compare it to the initial performance results that were shared by djm34 when he initially announced the crowdfunding of the project early last month. So the development of the miner hasn’t stopped and you can show your support by donating to the project to keep the developer motivated and to reach the goal of making it public for everyone.

ccMiner NeoScrypt performance:
GTX 980 – 554 KHS
GTX 960 – 304 KHS
GTX 750 Ti – 149 KHS

There are some important notes regarding the parameter throughput that is used by the miner, it seems that for us value of 1 works best for GTX 980 and GTX 960 bringing a more consistent and high performance. The performance of the GTX 980 is not affected much by the throughput option, so it works without it pretty well, but the GTX without the extra option provides just about 50-60 KHS. For GTX 750 Ti there seems to be not much of a difference what setting we use or throughput in regards to the hashrate we are getting, although a value of 1 does seem to also provide a more consistent hashrate, but your results may vary. Do note that the results posted above are from a reference GTX 750 Ti and GTX 980 video cards that are running at their stock frequencies while the GTX 960 GPU is a factory overclocked ASUS Strix GTX 960. This clarification is important when you take into account the hashrate that the GTX 960 has as compared to the GTX 750 Ti – double, and more that 50% that of the GTX 980 card.
