You Should Use ccMiner Alexis-1.0 for Better X11-Gost Hashrate

16, Feb 2017

The recent addition of the X11-Gost algorithm on NiceHash that is being used by SIBCoin (SIB) has increased the user interest in the coin and the algorithm as expected. NiceHash has recommended the use of the latest release of ccMiner by tpruvot for X11-Gost support on their servers, but it seems that this is not the fastest solution available to Nvidia miners as was pointed out to us. While ccminer v1.8.4 from tpruvot does about 8 MHs on a stock GTX 1070 GPU, but you can get faster speeds on the same hardware by using the latest ccMiner fork from alexis 78 (source). We have compiled a 64-bit Windows binary with Compute 5.x support and CUDA 7.5 for Nvidia Maxwell GPUs from the latest source for mining X11-Gost (SIBCoin) and with it you can get about 10-11 MHs on a stock GTX 1070 GPU.

Do note that on mining rigs with multiple GPUs you might need to increase the amount of virtual memory (SWAP file) if you have less system memory in order to be able to run the miner with the default high intensity. On a 6x GTX 1070 GPUs mining rig with 8GB RAM we’ve had to increase the virtual memory to 24GB in order to be able to run the miner properly at the default intensity of 22 set for the X11-Gost algorithm in the miner, otherwise the miner just crashes… 8GB RAM and 20GB SWAP file was not enough apparently.

Updated ccMiner 1.8.3-git fork by tpruvot With Improved LBRY Support

28, Sep 2016

ccminer-1-8-3-git

A quick update with a new Windows binary compiled from the latest ccMiner 1.8.3-git fork from tpruvot (source) with some improvement in the LBRY mining performance based on Alexis Provos work and basic implementation of the Veltor algorithm with some other minor fixes. The release below includes two versions of ccMiner, one is 32-bit binary for Windows that is compiled with CUDA 7.5 and with support for Compute 2.0 or newer Nvidia GPUs, and another that is 64-bit Windows binary compiled with CUDA 7.5 for Compute 3.5 or newer Nvidia GPUs. We have tried compiling the 32-bit version of ccminer with CUDA 6.5, but the resulting version did have some issues with LBRY, so we have compiled with 7.5 as well and it worked fine.

Official ccMiner 1.8.1 fork by tpruvot With SiaCoin (SC) Support

11, Aug 2016

ccminer-1-8-1-tpruvot

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.
