Claymore Dual Ethereum GPU Miner - Overview and Installation

December 31, 2018 | AtoZ Markets – Claymore Dual Miner is a computer software dedicated to those Ethereum lovers, that is said to have a more advanced technology to ease the mining process and make use of the entire potential of the graphics card, which is known to be the basic factor to consider when it comes to mining.

Bearing the name “dual miner”, Claymore’s top feature is that it enables the user of mining Ethereum, in addition to another another cryptocurrency like Decred/Siacoin/Lbry/Pascal at the same time without losing too much efficiency of the system.

Claymore was reported to have updated its dual Ethereum plus DCR, SC, LBRY, PASC, Blake2s and Keccak AMD and Nvidia GPU miner with some performance improvements for slower Nvidia GPUS as well as increasing the usability of older GPUs with less VRAM along with new features and bug fixes.


Some of the improvements are:

“improved hashrate for weak Nvidia cards by about 1%.

– zero devfee for 3GB cards in Windows 10, same as for all 2GB cards.

– applied some tricks to increase available memory for 3GB cards in Windows 10 so you can mine ETH a bit longer.

– now you can press “y” key to turn on “Compute Mode” in AMD drivers for all cards (Windows only).

– Linux version: removed openssl library dependency.

– improved “-logfile” option, now you can use it to specify a folder for log files, use slash at the end to do it, for example, “-logfile logs\”.

– added “-epoolsfile” and “-dpoolsfile” options.

– remote management: now “miner_getstat2” command also returns PCI bus index for every GPU.

– a few minor bug fixes and improvements.”

Claymore is one of the most efficient and convenient mining software as tech reports describe it, winning the general recognition of miners.

The miner can be configured in two methods: “Great”, giving a noticeable outcome, with some of the rewards going to the Claymore developer, and “Good”, with a lower performance, with no fees deducted from what is gained.

To create a quick walkthrough on how to use it, we are going the “Great” way in this article.

How to Set Up Claymore:

The Bitcointalk forum thread: bitcointalk.org/index.php?topic=1433925.0. hosts the installation file, so you can download it from there.

It is usually packed as an archive file, for which you will need a decompressing software to extract the files to a destination of your choice on your computer.

Once downloaded, unpack the compressed file anywhere on your computer, where you will get a new folder containing the installation files.

In the folder that contains the miner,

After that, you need to create a file that ends with the extension of “.bat”.

For that to happen, you will need to use a text editing program. Microsoft Windows Notepad does the job.

When you save the file, it’s important

Remember to choose ‘All Files’ as a file type, not ‘txt’ when saving, otherwise, you’ll have a file ending with “.bat.txt” at the end of the file name, which will result with the miner not being able to open this file. Your bat file (let’s suppose it’s called “yourname.bat”) should contain the following text strings:

setx GPU_FORCE_64BIT_PTR 0

setx GPU_MAX_HEAP_SIZE 100

setx GPU_USE_SYNC_OBJECTS 1

setx GPU_MAX_ALLOC_PERCENT 100

setx GPU_SINGLE_ALLOC_PERCENT 100

EthDcrMiner64.exe -epool eth.2miners.com:2020 -eworker RIG_NAME -ewal WALLET_ADDRESS -epsw x

WALLET_ADDRESS can be found in your wallet that you’re supposed to already have.

As for the RIG_NAME –, you can choose any name, as long as it falls within the 32 symbols limitation, containing only letters and numbers (without any special characters like $%»*;@).

As soon as the file is ready, open it – mining is on now, bearing in mind that Microsoft Windows might detect the “.bat” file as a harmful operation, resulting in blocking it from being executed. To avoid such a thing, you need to grant the file the permission to run once you’re promoted for that when launching it.

The statistics can be checked on the pool by typing your WALLET_ADDRESS in the search bar at the top.

As an important note, multi-GPU systems need more Virtual Memory size in Windows, at about least 16 GB:

The path to set the virtual memory in Widows is like the following: ("Computer Properties / Advanced System Settings / Performance / Advanced / Virtual Memory".).
