eqm-new

There is a new miner for Nvidia CUDA GPUs available for mining Zcash (ZEC) promising a slightly faster hashrate than the currently fastest implementation of the NiceHash EQM Zcash NVIDIA miner. The most important thing about this new miner is that it is not limited to only mining on NiceHash, so even with the same speed it is still a nice thing to have as it supports Stratum mining on other mining pools besides NiceHash (it does seem to support NiceHash’s Extranonce Subscribe as well). According to the author of the miner it is designed for Nvidia Pascal GPUs, but should work on older Compute 3.0 or higher Nvidia GPUs with at least 1 GB of video memory. Do note that the miner is not open source and there is only a Windows 64-bit binary release available at the moment, it does not seem to be based on other popular codebase and is not being reported as malicious software by antivirus products. You might still want to have something in mind as the user that posted it on Bitcointalk is a new account and not an established miner developer, even though it seems that the miner does work pretty well.

The EWBF CUDA Zcash Miner has a built-in developer fee that is set at 2%, meaning that every 10 minutes the software will switch to a different pool and mine for the developer some shares and then get back to mining for you. The author of the software claims speeds of about 250 H/s for Nvidia GTX 1070 while the NiceHash EQM miner does currently about 220 H/s on the same GPU. Our quick tests showed a hashrate of about 235-240 H/s average (up to 250 H/s) on stock GTX 1070, so still slightly faster, but not as much as you may want it to… then there is the dev fee as well and it seems that we are seeing somewhat more rejects than, especially when switching to mine for the dev fee. So while this may be an interesting alternative for users willing to mine outside of NiceHash, the actual performance that you may get poolside may not be much different than with what is currently the fastest implementation from NiceHash (taking into account the dev fee and the rejected shares)…

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.

AMD GPU miners were recently getting quite the boost thanks to Claymore’s Zcash miner on Windows, but now Windows users with Nvidia GPUs also got a nice boost in ZEC mining performance thanks to the release of the NiceHash EQM Zcash Nvidia Optimized Miner. It kind of doubles the performance that people were getting with the previous nheqminer from Nicehash, so now with a 6x GTX 1070 GPUs for example you can be all the way up to about 400 H/s. Do note that the miner currently supports only newer Nvidia GPUs and will apparently not work on anything lower than SM 5.0 capable GPUs – Maxwell or Pascal.

The only drawback is that the miner currently only supports connection to NiceHash, so you cannot use it with other pools. While this might nit be bad during the slow start of ZEC mining, after that you might still want to go for mining and keeping Zcash instead of immediately selling it for profit. Hopefully in the next few weeks we are also going to see more development happening for Nvidia users and that goes not only for Linux, but for Windows users as well.

Linux users would probably want to go and try the latest version of the Silentarmy miner that also brought support for Nvidia GPUs and is apparently providing similar performance as the NiceHash release for Windows. Also the Silentarmy miner is doing pretty well on AMD hardware, so do try it as well if you have such mining rigs and are running them on Linux.
