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:
– improved speed by about 15-25% (depends on card model). About 230H/s on stock 390X.
– added “-benchmark” option.
– 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.
– 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.
– 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.
– improved speed by 20-30% (depends on card model). Up to 80H/s on stock 390X on “-i 2” mode.
– improved stability.
– 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.
– improved speed by 5-15% (depends on card model).
– 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.
Claymore has just released his new miner targeted at Zcash (ZEC) miners and only for Windows at the moment, probably making it the fastest AMD OpenCL GPU miner at the moment for Windows OS. Do note that the miner is free, but there is currently a developer fee set at 2.5%, meaning that every hour the miner mines for 90 seconds for developer. According to Claymore this initial release is only for recent AMD video cards only: 7xxx, 2xx, 3xx and 4xx, 2GB or more and it does not support Nvidia GPUs with only Windows x64 binaries available at the moment for download.
A bit something about speeds with the new Zcash miner from Claymore, they are higher than what other Windows GPU miners were offering prior to the release of this miner (there are apparently faster Linux miners like SilentArmy’s V3 for example). A stock AMD Radeon 280X seems to do about 44-45 H/s, AMD Radeon 290X does a bit more at about 46-47 H/s, AMD Radeon 370 does about 35 H/s, AMD Radeon RX 480 does about 40-41 H/s in our initial tests. Feel free to share your hashrate results in the comments below if you do try the new miner…
Starting with Genesis Mining who have once more upgraded the Zcash cloud mining hashrate for their existing customers by another 25%. This means that everyone that has already purchased Zcash cloud mining hashrate from them got a nice boost in performance and amount of mined ZEC for free. Furthermore, new customers purchasing Zcash cloud mining hashrate will also get a boost in the hashrate they purchase, however the mining for new contracts purchased at the moment will start on December 1st and not immediately, so pretty much after the slow start for the mining ends.
The new Zcash (ZEC) cloud mining prices are the following after the last upgrade with 25% improvement in hashrate – 0.75 H/s for $29 USD, 7.5 H/s for $280 USD and 75 H/s for $2600 USD. These are up form 0.6 H/s, 6 H/s and 60 H/s for the same prices thanks to the hashrate improvement that apparently the company has achieved in their mining recently. Also don’t forget that you can use our special discount code during checkout to get 3% off the regular prices for Zcash mining hashrate, just enter CryptoMiningBlog5 as promo code during checkout to take advantage of the better price offer.
Another cloud mining service provider that has been available for quite some time already as well – HashFlare has also announced their plans for offering cloud mining hashrate for Zcash (ZEC). They have already started the presale of mining contracts with a price of 4.20 USD per 0.1 H/s with the launch of mining planned to start before 21.11.16, so you will be able to catch some of the slow start mining period as well. Each of their Zcash cloud mining contracts will last for 1 year (from activation) and will not have any additional fees as everything is apparently included in the price.
Their prices are now a bit higher than the above alternative since the latest announcement of hashrate upgrade, but there is an active promotional code for them as well that is following a recent Halloween promotion going for all knids of cloud mining hashrate being offered. You can use the promo code HF16HLLWN10 to get a 10% discount from the regular price of $4.20 USD per 0.1 H/s for the EQUIHASH cloud mining hashrate being offered at the moment. Do note however that this discount code will be valid only until 06.11.2016 23:59 (UTC +0) when the promotional offer will expire.
Besides the ability to rent and lease hashrate for the new Equihash mining algorithm being used by Zcash (ZEC) NiceHash is also offering what they call Fast Zcash Cloud Mining Contracts. These are 24 hour mining contracts, but with a large amount of hashrate that you are getting for this short period of time. This is an interesting alternative to long term cloud mining contracts, but probably not the best one for the moment while we are still in the slow start of mining for Zcash. Still a nice alternative to have to long term contracts as well as to traditional renting of hashrate where the price may vary and here you have a fixed price for the day.
Another popular service for renting and leasing hashrate, namely Mining Rig Rentals has yet to introduce support for the new algorithm used by Zcash (ZEC), so for the moment it is not interesting option for people that are all into Equihash. With the big interest however we are not going to be surprised if they don’t take much time to also introduce Zcash support in the next days.
