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.
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.
Here is another quick update of the ccMiner fork by tpruvot with a new Windows binary we have compiled from the latest ccMiner 1.8-dev (source) that comes with improved hashrate for Lyra2REv2 thanks to the Nanashi Meiyo-Meijin improvements as well as faster Decred hashrate thanks to Alexis Provos improvements getting integrated. There are some other fixes and some new features using nvapi, this release also includes support for the X11 Evo algorithm, so you might want to give it a try if you are currently using different forks of ccMiner for different algorithms. The Windows binary is a 32-bit one compiled with CUDA 6.5 and with support for Compute 2.0 to Compute 5.2 Nvidia GPUs and will also work on the newer Pascal Nvidia GPUs even though it is not CUDA 8.0 binary. So do give it a try if you are GPU mining anything other than Ethereum on your Nvidia GPUs at the moment…
