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.

NiceHash EQM Zcash Nvidia Optimized Miner for Windows Now Available

12, Nov 2016

eqm-cpu-nvidia-nicehash-miner

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.

The Latest Zcash (ZEC) Miners to Use for Your Mining Hardware

2, Nov 2016

zcash-nicehash

Here is a quick list of the latest CPU and GPU miners available for mining the Zcash (ZEC) that uses the Equihash algorithm used by the coin. Since most pools and miners are based on Stratum mining support you should be able to use them on almost all mining pools with support for ZEC. What you should be looking for is what works best on your hardware in terms of stability and what provides you with the optimal hashrate in order for you to maximize your profit. CPU mining is still viable as GPU miners are yet to be further optimized to be able to provide significantly higher hashrates, though you should know that the days of the CPU mining of ZEC are probably numbered.

Because of the slow start mining that Zcash has implemented the block reward is still growing, so even with price going down and the total network hashrate going up the overall profit for mining and selling Zcash remains pretty stable and most importantly pretty high compared to other crypto coins at the moment. Because of that it is a wise decision to mine and sell Zcash at the moment until the end of the slow start of mining when the block reward will stabilize at the maximum level of 12.5 ZEC and that should provide a more stable price per coin than at the moment. Mining ZEC coins now and keeping the coins may result in them loosing significant value at least in short term, though in long term it might still be a viable option, so consider what to do carefully.

Best CPU miners for Zcash:
– NiceHash’s nheqminer v0.3a (also supports CUDA and OpenCL)*

Best AMD OpenCL miners for Zcash:
– ZECMiner v0.6 by Genoil

Best Nvidia CUDA miners for Zcash:
– NiceHash’s nheqminer v0.3a (also supports CPU and OpenCL)*

* The nheqminer is available with hardcoded pools from nicehash, suprnova and other mining pools supporting Zcash, so make sure you download the correct version for the pool you are going to be mining at.

Genoil’s latest ZECMiner is pretty much the fastest public OpenCL miner (Windows binaries only) for Zcash at the moment, though there are some stability issues with cards dropping to 0 Sol/s and the miner crashing. The situation improves with each new version, but the miner is still not that good stability wise. The latest Nheqminer supports OpenCL mining, but is slower than ZECMiner, even though stability wise it is better… it is much better for CPU and CUDA mining though. Hopefully soon there will be other faster GPU miners that will offer more stability and features along the improved mining speeds, but for now you will need to do with what is currently available.
