ethminer-cuda-pool

Ethereum launched Frontier – the first release of the project including actual mining of Ether with CPU and GPU at the end of last month. The Frontier release comes with a command line only interface with a Javascript environment that allows building, testing, deploying and using decentralized applications on the Ethereum blockchain. Ethereum is being described as a decentralized platform that runs smart contracts: applications that run exactly as programmed without any possibility of downtime, censorship, fraud or third party interference. So far the available code is mostly intended for developers and though the network is active it is not very user friendly to normal people that might be interested in trying to mine some Ether. Ethereum’s next release named Homestead is supposed to offer in a few months a user friendly interface for normal users.

We have prepared a short guide that should get you started with Ethereum mining using the Frontier release on Windows and we have prepared the required software to create your own address as well as how you can mine solo or in a mining pool using either your CPU or GPU (OpenCL or CUDA). We want to warn you that although getting started with the basic usage and mining may not be that hard, to be able to take advantage of all of Ethereum’s features you’d need to spend some more time getting to know it as it things are not like with your average Bitcoin clone. We are going to be using geth (source), ethminer (source) and ethminer-cuda (source), you can download the package containing the Windows binaries for both from the link below then you need to follow the following instructions:

Generating wallet address:
– Open the geth folder and run geth-console.bat to start Ethereum in console mode
– The software will need to download the blockchain data, it can take some time
– In the console type: personal.newAccount("password")
– Instead of password in the quotes above write your own password and remember it well
– In the console type: eth.accounts
– This will list your Ethereum wallet address
– To check your account balance you can type: web3.fromWei(eth.getBalance(eth.coinbase), "ether")

Sending Ether to another wallet:
– First you need to unlock your account by typing in the console the following (replace password with your password): personal.unlockAccount(eth.accounts[0], "password")
– In the console type: eth.sendTransaction({from: 'your_address', to: 'recipient_address', value: web3.toWei(1, "ether")})
– In the above code replace your_address and recipient_address with the respective addresses, the example is for sending 1 Ether, but you can change the value depending on your needs

Mining locally on the CPU:
– Run geth-console.bat and to start CPU mining type: miner.start(4)
– The number in the quotes is the number of threads to use
– To stop CPU mining locally type: miner.stop()

Pool CPU/GPU mining using ethminer:
– Open the ethminer folder and edit the three bat files with your wallet address
– For CPU mining on the pool run: pool-cpu.bat
– For OpenCL mining on the pool run: pool-ocl.bat
– For CUDA mining on the pool run: pool-cuda.bat

The ethminer software uses the ethpool mining pool for mining, the pool fee is 2% and there is a flat fee of 0.01 Ether per payout charged with minimum payout of 1 Ether, also the pool is beta and there could be some issues. The geth software contains only CPU miner while ethminer supports CPU (up to about 2 times faster than geth CPU mining), OpenCL GPU mining for AMD (also works on Nvidia) and CUDA GPU mining. You can use OpenCL mining on Nvidia GPUs as well, could work on older GPUs that do not work with the CUDA miner. If you have integrated GPU it can also be detected as OpenCL capable and the miner may try to run on it, so you can try to use the --opencl-platform and --opencl-device command line parameters to avoid the problem.

Mining performance:
– ethminer CPU mining on Intel Core i7 5820K: 0.95 MHS
– ethminer OpenCL mining on AMD Radeon R9 280X: 24.4 MHS
– ethminer OpenCL mining on Nvidia GeForce GTX 980 Ti: 18.5 MHS
– ethminer CUDA mining on Nvidia GeForce GTX 980 Ti: 18.7 MHS

Do note that ethminer is 64-bit only and you need to have Visual C++ 2013 Redistributable installed (the 64-bit version) as it is compiled with Visual Studio 2013 and CUDA 7.5RC. Note that it seems AMD is currently faster mining Ethereum as compared to Nvidia GPUs and CPU mining is not much worth other than for testing purposes anyway.

Download geth and ethminer compiled for Windows and ready to be used…

What about the drivers, maybe older version? Is CPU mining working just fine on that system?

You can try downloading the archive with the files again, it now includes two versions of ethminer to try – one for CUDA (also supports OpenCL and CPU) and one with OpenCL and CPU only.

I get the same error for HD 6950 2GB gpu card with the latest AMD Drivers, AMD APP SDK and 2013 C++ redistribution installed. Also, this article should have shown how to solo gpu mine too. The pool get a few too many RPC connection lose, so that a lose in mining hash.

R4zor3dge

August 13th, 2015 at 23:27

I meant “gets too many…”, “connection loses” and “that’s a lose in mining”.

As far as the older AMD/ATI cards, maybe the miner is only optimized for the Radeon HD 7XXX and later cards…..

and it stops without any error/warning,…any ideas how to get it working,…it’s same for CPU and GPU (cuda)

admin

August 14th, 2015 at 09:39

ETH mining seems to be still buggy and not optimized, a lot of people still seem to have problems, hopefully this will be resolved with updates of the miner software. So try both versions of the ethminer, the CUDA one also supports OpenCL and CPU mining.

Solo mining is not entirely problem free, we have tried with a single GPU for a day and sometime along the day geth got in some kind of loop and was not sending work for new blocks, but was stuck at sending work for an older block that has already been solved. So solo mining can also give you problems and the risk there is higher, though if lucky you can make more than pool mining. A guide for solo mining Ethereum is coming…

I keep getting an error about “illegal memory access” for my 560Ti. Does anyone know what’s wrong and what I have to do to fix it?

The CPU miner works perfectly… albeit slow.

admin

August 14th, 2015 at 16:25

If you are having trouble with Nvidia GPUs running the CUDA miner, then you can try to use them with OpenCL… it could work and the difference in performance is usually not much.

Nynto

August 14th, 2015 at 16:35

I guess you need a gpu with more than 1GB memory.

Hello,

I have downloaded the files, etc. but I still can’t understand from your post how I can mine with my GPU Cuda or smth else.
If I want to use GETH, what .bat file should I create for solo mining, what should I write there?

I run on Gerforce SLI GT 755M (2 graphics cards)

could you please reply and help me set it up correctly, thank you.

ethpool has stopped accepting new miners for the moment (new wallet addresses), so that is why it is now rejecting new user connections. You can try solo mining as unfortunately we are not aware of an alternative pool available for the moment.

admin

August 16th, 2015 at 18:24

nhulongpm, in the command try to replace eth.coinbase with your wallet address in quotes and see if it will work.

CoinYourBit, Google loves to mark all the mining software as a possible malware… we are constantly asking to get the site reviewed and get these false warnings removed. The source code is linked in the article for anyone that may have some concerns, you can compile yourself or download some of the other pre-compiled binaries.

Hi All, I am running Windows 10 on an Intel Celeron 1.8GH. I have downloaded the files, started geth-console.bat and still having this since 4 days. Wi-Fi has been disconnected sometimes. Does it take so long to generate a wallet address ?

Thanks

admin

August 29th, 2015 at 11:36

The wallet address can even be generated when you are offline, make sure you follow the guide on creation of the wallet.

Guido

August 30th, 2015 at 17:06

So if the last line in console is:

I0829 15:07:32.713816 8280 chain_manager.go:661] imported 1 block(s) (0 queued 0 ignored) including 0 txs in 8.0076ms. #160231 [5deaa65f / 5deaa65f]

Does it mean that I have the entire blockchain and can move to the adress creation ?

Thanks

admin

August 30th, 2015 at 18:51

Guido, it means that you are synchronizing the blockchain, you can see the number of the block and compare it to the latest from a blockchain explorer to make sure.

Guido

Ok, perfect it worked on Windows 10.

What about the options in “pool-cpu.bat”
ethminer -F http://us1.ethpool.org/miner/walletadresse/0.1 -C
If 0.1 is the hash rate, what is C ? G ? what about the other options ?

Full example to mine with a 10MH/s ethminer instance to address 0xe6a7a1d47ff21b6321162aea7c6cb457d5476bca on ethpool US server under the name worker1:

ethminer -F http://us1.ethpool.org/miner/0xe6a7a1d47ff21b6321162aea7c6cb457d5476bca.worker1/10 -G (+ your usual options)

-C is for CPU mining, since the hashrate of a CPU is much smaller compared to GPU you need lower difficulty.
-G is for GPU mining using OpenCL, should work on both AMD and Nvidia-based video cards.
-U is for GPU mining using CUDA, you need to use the CUDA-capable miner as the standard one is only for OpenCL.

Hello Mr. X and Bojadin,

how it works with the 6990? Whats the hashrate?

Please help

Thanks

Thanks admin, now i’ll update or invest in hardware since my estimated earnings per months shows Ξ0.02841

Most of articles Ive read, says that cpu is not worth anymore, but if you have:

Is this worth mining ethereum?

I’m taking my first steps in the “mining” so – i need you advice :\

Thank you

If you also have free electricity it might be somewhat worth it… otherwise CPU mining is pointless.
There are other crypto coins that are CPU only or mining with CPU is not much slower than GPU mining.

Thank you for your reply admin.

Maybe a little out of topic (sorry) but could you advise me to start mining a specific crypto coin to take advantage of this cpu’s?

^CTerminate batch job (Y/N)?

just downloaded and started the ethereumpool-cuda.bat just to see what kind of performance I would get. however I cant seem to get it to utilize both of my Video Cards
it only seems to hash on GPU2 for some reason

I tried adding –gpu-devices 2 but it did not help

Thanks in advance for any help

Figured it out… –gpu-devices 0 1

Goodnight everyone, I’m trying to mine with my Zogis video card Gforce 6500 1gb ddr2. however appears a driver mensangem cuda wrong version. already installed the nvidea driver straight from the site, both in windows 7 as the 10 in opcl also does not work in certain mining CPU. I’m just not getting the video card. Anyone know why?

If the miner is running only on the first GPU you can manually set all GPU IDs via the command line, so that they all are going to be used.

Am I up and mining now? or is it just running in a loop? I did everything right in the instructions. I am running windows 10 on Nvidia Geforce Gtx 960M with an intel core i7. any info would be greatly appreciated.

You can use -h or –help to get the list of available options, the downloadable archive comes with help.txt files with commands as well.

i think my miner is running perfectly as picture shown above but when i go to the pool and paste my account detail and check status, it give me an:

Error: Account ‘9d703459d03ad3d55a354e414f161f4a5c02410a’ not found!

what does this mean? how do i know if my shares are being accepted or not?

Hi there.

I have a Radeon HD 6950 with 2 GB RAM and after trying and trying it still gives me the
“clCreateBuffer(-61). PU can’t allocate the DAG in a single chunk. Bailing. clEnqueueWriteBuffer(-38)
Error by mining with 0 H/s

I have the newest “Crimson Edition 16.2.1 Hotfix” Driver from today came arround first March 2016.

CPU Mining works.

Does anyone know the fix AND is going to tell? :/

almohtarif, if you are solo mining you need to first hit a block and then you will have a local balance available, but with that low hashrate solo mining is literally pointless. If you are pool mining you should check your stats on the pool, based on the pool payout minimum and timeframe it will again take some time before any coins are sent to a local wallet.

admin

March 19th, 2016 at 15:22

If you have a GPU with 2GB of memory and receive the following error: “Allocating/mapping single buffer failed with: clCreateBuffer(-61). GPU can’t allocate the DAG in a single chunk. Bailing.” You can try setting the GPU_SINGLE_ALLOC_PERCENT environment variable to 100 by running in the command line the following command before the miner: SET GPU_SINGLE_ALLOC_PERCENT=100 to see if it will fix the problem.

Hello,

I got a GPU doing around 5MH/S and I decided to mine solo for now. I read about not being connected to the internet while mining solo shouldn’t make problems. Can you confirm that? In which periods do I have to start geth –rpc to keep the chain up synchronized, especially for solo mining?

Regards

admin

March 24th, 2016 at 21:03

There is no point to try solo mining with just 5 MHS. You need to be online when mining in order to have a synchronized blockchain.

Hello everyone,

Why is the blockchain so massive in data storage? The target is 1920000 and I’m currently at 917246, the data files currently amount to 7GB. This means the folder will be a huge amount by the time the block has finished syncing.

Is this normal? Thanks in advance.
