Use the sgminer 5.6.0 Nicehash Fork for X11-Gost (SIBCoin) Mining

17, Feb 2017

At the moment Nvidia GPU miners have the advantage for mining X11-Gost with a faster hashrate for the more recent Maxwell and Pascal GPUs than AMD miners. Still AMD miners might be interested in checking out the X11-Gost algorithm used by SIBCoin (SIB) as it is not that power hungry and with the increased interest with the recent addition of the algorithm on NiceHash as it might offer a nice profitability for users willing to sell their hashrate and get paid in Bitcoins directly.

So if you are using AMD GPU mining rigs you might want to check out X11-Gost on NiceHash using the latest sgminer 5.6.0 Nicehash Fork (source). We are seeing a hasrate of between 7 MH/s and 8 MH/s on stock Radeon RX 480 and while still slower than about 11 MH/s on a stock Nvidia GTX 1070 the fact that the algorithm is not that power demanding and you can use lower power for the GPUs may make it attractive for some users, so do give it a try. Older generation of AMD GPUs may not be the best choice for this algorithm performance wise and the same pretty much goes for older Nvidia GPUs, but for AMD Polaris and Nvidia Maxwell and Pascal it is.

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.

Claymore’s Zcash AMD Miner is Really Killing Everything Else Performance Wise

15, Nov 2016

claymore-zcash

Claymore’s Zcash (ZEC) AMD miner has been updated a couple of times already since the release of the initial version from some days ago. The number of optimizations and hashrate improvements with pretty much each major update has been tremendous, bringing back to life many of the old AMD Radeon GPUs such as 7950/7970 or the 280X, some of the most popular mining video cards for the last few years. The latest release, already a major version 6 brought more fixes and optimizations in terms of performance. As one would expect Nvidia is left behind once more, even though there were some signs that recently it was starting to catch up to the levels of performance of AMD GPUs, it is now yet again significantly slower. So owners of Nvidia-based mining rigs might want to switch to some other alternative for mining at the moment after the latest performance boosts from Claymore. Do have in mind however that Claymore’s Zcash miner does come with a 2.5% dev fee, below is a list of major changes and updates of the miner after the initial release:

Version v7.0:
– improved speed by about 15-25% (depends on card model). About 230H/s on stock 390X.
– added “-benchmark” option.

Version v6.0:
– improved speed by about 20-25% (depends on card model). About 180H/s on stock 390.
– “-i” parameter values are 0…4 now, default value is “-i 4”.
– fixed issue with mixed cards.

Version v5.0:
– improved speed by about 30-50% (depends on card model). About 145H/s on stock 390X.
– improved support for Catalyst 16.x and 4xx cards.
– reduced CPU usage.

Version v4.0:
– improved speed by about 20% (depends on card model). Up to 100H/s on stock 390X on “-i 2” mode.
– added “-retrydelay” option.
– added “-nofee” option.
– various bug fixes.
– changed coloring.
– EthMan: added “View miner console” command.

Version v3.0-v3.1:
– improved speed by 20-30% (depends on card model). Up to 80H/s on stock 390X on “-i 2” mode.
– improved stability.

Version v2.1:
– added “-i” option for adjusting mining intensity and CPU usage.
– improved speed for high intensity mode (“-i 2”), about 60H/s on stock 390X, 50H/s on stock 280X.
– since nicehash cannot upgrade their ddos protection, now “-allpools 1” is required for this pool.

Version v2.0:
– improved speed by 5-15% (depends on card model).

Version v1.1:
– added Linux version.
– fixed issue with rejected shares after devfee mining.
– remove “-allpools 1” option if you use it and mine on miningpoolhub, suprnova, coinmine or nicehash pools.
– added “XnSub” support for Nicehash.
– fixed bugs.
