You Should Use ccMiner Alexis-1.0 for Better X11-Ghost Hashrate
The recent addition of the X11-Ghost 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-Ghost 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-Ghost (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-Ghost algorithm in the miner, otherwise the miner just crashes… 8GB RAM and 20GB SWAP file was not enough apparently.
