Claymore’s Dual Miner now offers support for both AMD and Nvidia GPUs for both Linux and Windows (binary only releases), so you can dual-mine Ethereum and SIA or DCR at the same time or only use the miner for Ethereum mining. Using Windows 7 is recommended for Nvidia video cards all the way up to Maxwell and Windows 10 updated and with the latest video drivers or Linux is recommended to be used for Ethereum mining, regardless if you use the dual miner or other Ethereum mining software. The latest version 6.3 is no longer beta and it also adds support for NVIDIA 10xx cards in Linux, there are only 64-bit binary builds available though.

Claymore is also making available a modification for a driver for Nvidia Pascal GPUs (GTX 10xx series) for Windows 7 that should work better than the standard ones, so if you are using GTX 1080, GTX 1070 or GTX 1060 on Windows 7 you can check the driver out as well. The Dual miner has support for both Getwork and Stratum for Decred (DCR) as well as Getwork and Stratum for SiaCoin (SC), however not all Stratum implementations are currently supported as there are multiple ones used by different pools!

Claymore has released a Linux binary of his Dual Ethereum and Decred GPU miner for AMD GPUs. Prior to that the dual miner was only available for Windows users, but now Linux miners can also try to run it and increase their mining profit by mining ETH and DCR at the same time. Do note that the Linux binary may not work on all Linux distributions, it is tested on Ubuntu 12.04 and Catalyst 15.12 and other users are reporting success on other Ubuntu versions, but there are also some that have issues. The Linux binary of the miner is 64-bit only and if you are trying to run it on your mining rig please report if you are successful or not and on what Linux distribution. With Linux it is usually best to compile from source code, but since Claymore’s Dual Ethereum and Decred GPU miner is not open source and there is a small developer fee the source is not available for miners to compile it themselves. Still a Linux binary is better than nothing at all, meanwhile it seems that SP is also experimenting on a dual miner for Nvidia GPUs as Claymore’s miner is working only on AMD.


Claymore has been quite active in further developing his dual miner for AMD OpenCL GPUs intended to mine both Ethereum (ETH) and Decred (DCR) since our initial post about his first release a few days ago. The latest updates include some of the features we noted as missing in the initial release such as Stratum support for Decred or the ability to set workers for Ethereum mining pools. The more interesting improvements however are those relates to the performance you get from the miner, he has been able to squeeze some extra performance in terms of the hashrate you get for mining Ethereum while at the same time you still get decent performance for mining Decred as well.

The earlier versions showed a bit of a decrease of the performance in Ethereum while using the dual mining mode, but the latest improvements have significantly improved the situation, including the results for slower AMD GPUs. With the latest version 3+ you can get slightly more Ethereum mining hashrate than with the regular ethminer while at the same time you are also mining some Decred. The higher-end the AMD GPU you are using, the higher performance gain you can expect – from about 1 MHS on 79×0/280x cards to a few on 290/390 series of cards plus the extra Decred mining hashrate. Interestingly enough not mining in dual mode, but only Ethereum is not showing difference in the hashrate now on a Radeon R9 280X for example.

So if you still have not tried the Claymore Dual Ethereum and Decred Miner for AMD GPUs (it does not work on Nvidia video cards), you should give it a try. Do note that although this miner is free-to-use, there is a small developer fee of 1% for Ethereum-only mining mode and 2% for Ethereum plus Decred mining mode, so every hour the miner mines Ethereum for 36 or 72 seconds for developer. Also, if you have been mining only Ethereum for the moment and you switch do dual mining mode adding Decred you should know that the power usage and the heat generated by the GPU will increase. So make sure your AMD GPU mining rig can handle the extra power usage and heat generated when dual mining, because Ethereum is less power hungry and more memory than GPU demanding algorithm while the situation with Decred is the right opposite and thus both can be mined together with pretty good results. Another important thing to note is that the miner is only released as a Windows binary, no source code or binaries for other operating systems are currently available.
