In this second installment of our DIY Ethereum mining guide, we’ll look at how to install and configure Linux to setup your rig as an automated, remotely-manageable appliance. Don’t be dissuaded if you’ve never used Linux before—our step-by-step guide makes it simple!
Why Linux over Windows? First, it’s free—and saving ~$100 on the operating system is a big plus when you’re trying to maximize profitability. Other reasons include lesser hardware requirements (Linux is perfectly happy running from a USB stick plugged into ancient hardware!), simpler remote administration capabilities, and oftentimes better stability. The downside of running Linux is that video driver support isn’t on the same level as Windows, and things like GPU undervolting are trickier (but still possible via BIOS mods).
If you missed the hardware portion of our guide, make sure to check it out first. Otherwise, read on.
Build an Ethereum Mining Rig, part 2: Linux Setup
The following is heavily adapted from my original 2013 Litecoin mining guide, updated for the latest Xubuntu LTS version, the new AMDGPU-PRO drivers, and necessary ethereum mining software (all up-to-date as of 11/29/2017). If you’re a bit nervous because you’ve a complete Linux newbie, don’t be. Simply follow the step-by-step instructions exactly as they’re written, and you’ll be fine. Even if you’ve never done anything like this before, you should be up and running in roughly an hour.
Step 1: Configure BIOS settings
Before we even get to Linux, let’s take a minute to make sure that your mining computer’s BIOS settings are in order. Power on your computer, and press the “delete” key a few times immediately after power on. You should end up in the BIOS configuration area. Do the following, then save & exit:
- Change power options so that the computer automatically turns itself on whenever power is restored. The reason for this is two-fold: first, it’ll make sure that your miner automatically starts up after a power outage. Second, it makes powering the computer on much easier if you don’t happen to have a power switch connected to the motherboard.
- Make sure that your USB stick is first in the boot-up order (you may need to have a USB stick attached).
- Disable all components that you don’t plan to use. This may save a little bit of power, and since your miner will likely be running 24/7, it’ll add up. For me, that meant disabling onboard audio, one of the SATA controllers, the USB 3.0 ports (I only had a 2.0 USB stick), the Firewire port, and the serial port.
- If you’re running a lot of GPUs (4+), additional tweaks might be necessary to ensure that they’re all recognized by the OS. Exact tweaks vary by motherboard, but setting the PCIe speed to Gen1 is usually a good place to start. No need to change anything now, but make a mental note that you may need to come back and play around a bit if all of your GPUs don’t show up in the OS later.
Step 2: Install Xubuntu Desktop on your miner
Xubuntu is a lightweight version of Ubuntu, a popular Linux distribution. Most other distros should work just fine, but be aware that the GPU drivers require the presence of Xorg, which means server distros that don’t have a GUI will not work properly.
- Xubuntu 16.04.3 is the latest LTS release at the time of this guide, so that is what I recommend you use. You can download it here.
- You’ll need to either write the installation ISO image to a USB stick (highly recommended), or burn it to a DVD. If you use a DVD, you’ll need to temporarily hook up a DVD drive to your mining rig for the installation (make sure you temporarily enable your SATA controller if you disabled it in step 1!).
- Once you have the installation media prepared, you’re ready to install Xubuntu to your miner’s boot device (whether it’s an SSD, mechanical harddrive, or another blank USB stick). Boot using your new installation media (make sure it’s first in your miner’s BIOS boot order list). The Xubuntu installer should appear.
- Follow the prompts, and make sure to click the “auto-login” box on the last step of the installer (otherwise, all of the default options are fine).
- When the installation is complete, you should automatically boot into the Xubuntu desktop. Make sure to remove your installation media.
Step 3: Install SSH and package updates
At the Xubuntu desktop, press CTRL+ALT+T to open a terminal window.
- Install SSH by typing:
sudo apt-get install openssh-server
With SSH installed, you can unplug the keyboard/mouse/monitor from your miner, and complete the rest of the installation from your desktop computer. Simply download Putty onto your desktop, run it, and enter the IP address of your mining rig (type ifconfig at the Xubuntu terminal to find your miner’s address if you don’t know it—it will probably look like 192.168.0.x). That should bring up a remote terminal session to your miner, which is more or less just like sitting at the keyboard in front of it.
If you plan to manage your mining rig remotely over the internet, you’ll need to forward port 22 on your router to your miner. Make sure that you use a strong Xubuntu password!
Setup should be pretty quick from this point, as now you can simply copy text from this webpage (highlight it and press CTRL+C) and then paste it into your Putty session by simply right-clicking anywhere inside the Putty window. I highly recommend that you complete the remainder of the guide in this manner, as it eliminates the risk of typos!
- Install package updates by typing (or copying & pasting via right-click into Putty) the following command:
sudo apt-get dist-upgrade
Step 4: Install AMDGPU-PRO drivers
Next up, we’ll install AMD’s video drivers. AMD has special blockchain compute drivers available for mining that give far superior performance compared to their standard drivers, so that’s what we’ll be using (version 17.40, which is the latest as of 11/29/2017).
- Type the following commands (press “enter” and wait for the operation to complete at the end of each line):
cd ~/Downloads wget --referer=http://support.amd.com https://www2.ati.com/drivers/linux/beta/ubuntu/amdgpu-pro-17.40-483984.tar.xz tar -Jxvf amdgpu-pro-17.40-483984.tar.xz cd amdgpu-pro-17.40-483984 ./amdgpu-pro-install -y - Some of these steps may take a minute or two to complete. When the installation is complete, type the following:
sudo usermod -a -G video $LOGNAME - Next we need to install and configure the ROCm component:
sudo apt install -y rocm-amdgpu-pro echo 'export LLVM_BIN=/opt/amdgpu-pro/bin' | sudo tee /etc/profile.d/amdgpu-pro.sh - Finally we need to enable large page support, which will dramatically improve mining performance. Type the following to open your grub file in nano for editing:
sudo nano /etc/default/grub - Find the line that reads GRUB_CMDLINE_LINUX_DEFAULT=”quiet splash”. Modify it to:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash amdgpu.vm_fragment_size=9" - Save the file and quit nano by pressing CTRL+X and then answering (Y)es to save the changes. When you’re finished, update grub and reboot:
sudo update-grub sudo reboot
The final command will reboot your rig, which will cause you to immediately lose your SSH (Putty) connection. Wait a few seconds to give the computer a chance to boot, and then re-establish a new connection via Putty, and re-login.
Step 5: Install Ethereum software
(Note: you may skip step 5 entirely if you already have an ethereum wallet address that you intend to use!)
Next up, we’ll install the Ethereum software that will let us create a new wallet address. We’ll need this to store the coins we receive from mining.
- Type the following to install the necessary ethereum packages:
sudo add-apt-repository ppa:ethereum/ethereum sudo apt-get update sudo apt-get install ethereum geth - Now it’s time to create your Ethereum wallet address:
geth account new
You’ll be prompted to enter a password, and then to confirm it (use a strong password!). The output will be a long string between two curly braces { }. That’s your new wallet address—make a note of it (highlight it within Putty to copy it to your clipboard).
Important: The combination of the password you just used to create this address *and* the associated encrypted key file is what gives you control over your new wallet address. If you lose either of these, you’ve also lost control of your wallet and all of the coins associated with it—and there is literally nothing that anyone will be able to do to help you. Remember your password, and keep multiple backups of your key file(s)!
Your key file(s) are stored in the ~/.ethereum/keystore directory. Copy the entire /keystore folder someplace safe to backup your wallet (backups are covered in more detail here—don’t forget to make multiple backups and keep them in a secure offline location!).
If you forget your wallet address, you can type geth account list to see your addresses and the location of their key files.
Step 6: Install Claymore’s Ethereum miner
There are several options as far as mining software, and I’ve experimented with all of the popular ones. I think Claymore’s miner is the best option, even if it does have two fairly significant downsides: it’s closed-source, and it’s not free (~1% of your mining time benefits the creator of the miner).
Two alternatives are the stock ethereum miner (ethminer) and Genoil’s fork of the stock miner. They’re both open-source and free, but they have pretty crippling downsides.
The stock ethminer is much slower than Claymore’s miner (by a margin of over 5% on my test rig). In addition, ethminer creates the Ethereum DAG file on disk instead of in GPU memory, which is slow and uses a lot of space (and if you’re running off a USB stick, all those writes may eventually wear it out).
Genoil’s fork seems to be nearly as fast as Claymore’s, and it doesn’t use physical disk space for the DAG, but it’s not stable (at least not for me). It often crashes, especially on startup (whereas I have yet to see a single crash on Claymore’s miner after nearly a week of full-time mining). The author abandoned development months ago, so improvements are unlikely.
So, explanation aside, here is how to setup Claymore’s miner:
- First return to your downloads directory and grab the latest version (10.2 as of 11/29/2017). I’m pulling the file directly from the author’s Google Drive repository, if the link is broken check here for a newer release or updated link):
cd ~/Downloads sudo apt install curl curl -L -o claymore_10.2_miner.tar.gz https://drive.google.com/uc?id=1t25SK0lk2osr32GH623rR8aG2_qvZds9 - Then create a new directory for it, and unpack it there:
sudo mkdir /usr/local/claymore10.2 sudo tar -xvf claymore_10.2_miner.tar.gz -C /usr/local/claymore10.2 - Then let’s head over to the installation directory and create a startup script. Note that commands 2-5 below just clean up the installation directory a bit by removing an intermediary directory that was included in the original tar archive:
cd /usr/local/claymore10.2 cd Clay* sudo mv * /usr/local/claymore10.2 cd .. sudo rm -r Clay* sudo chown root:root ethdcrminer64 sudo chmod 755 ethdcrminer64 sudo chmod u+s ethdcrminer64 sudo nano mine.sh - Nano will open a new blank text file; enter the following into it:
#!/bin/sh export GPU_MAX_ALLOC_PERCENT=100 ./ethdcrminer64 -epool eth-us-east1.nanopool.org:9999 -ewal YOUR_WALLET_ADDRESS/Miner01 -epsw x -mode 1 -allpools 1 -tt 68Where it says YOUR_WALLET_ADDRESS, use the address you created in step 5 (you’ll need to put “0x” in front of it). The “Miner01” following your address can be changed to any friendly label that you want to give your miner (only important if you plan to run multiple rigs). It’s easiest to copy the last line from my guide into something like notepad, then replace YOUR_WALLET_ADDRESS with your actual address there, and then copy the finished line into putty via right-click to get everything into nano without typos.
- Save the file and quit nano by pressing CTRL+X and then answering (Y)es to save the changes, then enter the following to give your new script execute permission:
sudo chmod +x mine.sh
Note that I’m using nanopool.org as the mining pool here. I’ve tried a few, and it seems to be a top pick, but feel free to pick your own pool. Most don’t require registration, and simply payout to whatever wallet address you supply whenever a certain threshold is met (usually whenever you accumulate 1+ ETH). Assuming you stick with Nanopool, you’ll be able to check on your miner’s status by going to this URL after you start mining: https://eth.nanopool.org/account/[YOUR WALLET ADDRESS]
- Now is a good time to test things. You can fire up your miner by typing:
./mine.sh
You should see the Claymore miner start up. It’ll take a minute or two before it actually starts mining, but it should get there eventually. When you see a scrolling log of outputs that includes non-zero hashrates (expect hashrates in the low to mid 20s for unoptimized GPUs), you’re good to go. If the script fails to start, or you see errors, make sure that you’ve created the script exactly as outlined in the guide.
Press CTRL+C to exit the miner when you’re satisfied that it’s working.
Step 7: Create auto-start scripts
We’re almost done! We want to set up our rigs automatically start mining whenever the rig is powered on. That way, we keep mining losses to a minimum whenever a power outage occurs, and we don’t have to worry about manually starting it back up in other situations.
- First, install screen:
sudo apt install screen - Then type the following to create a new script in your home directory and open it in nano:
cd ~sudo nano miner_launcher.sh - Enter the following text into the editor (substitute your actual Xubuntu username for YOUR_XUBUNTU_USERNAME where necessary!):
#!/bin/bash DEFAULT_DELAY=0 if [ "x$1" = "x" -o "x$1" = "xnone" ]; then DELAY=$DEFAULT_DELAY else DELAY=$1 fi sleep $DELAY cd /usr/local/claymore10.2 su YOUR_XUBUNTU_USERNAME -c "screen -dmS ethm ./mine.sh" - Save and quit nano (CTRL+X), and then type:
sudo chmod +x miner_launcher.sh - Now we need to call our new script during startup; we do that by adding it to /etc/rc.local. Type the following to open /etc/rc.local in nano:
sudo nano /etc/rc.local - Add the following text, right above the line that reads “exit 0” (substitute your own username!):
/home/YOUR_XUBUNTU_USERNAME/miner_launcher.sh 15 &
Then save and quit out of nano (CTRL+X).
Step 8: Create an alias to easily check on the Claymore miner process
We’re essentially done at this point, but you’ll probably want to manually SSH into your miner from time to time to manually check on your hashrates & GPU temperatures, etc. Creating an alias will make that easy.
- Type:
sudo nano .bashrc - Scroll to the end of the file, and then add this text above the line that reads “# enable programmable completion…”
alias miner='screen -x ethm' - Save and quit out of nano.
That’s it—you’re done! You’ll probably want to run a full test now. The easiest way to do that is to close your Putty session and power down your miner. Turn it back on and the following should happen:
- Your miner should boot into Xubuntu. This may take up to a minute, depending on the speed of your boot device (it’ll be much faster on an SSD).
- 15 seconds after Xubuntu has loaded, the Claymore miner will automatically start and begin mining. You might notice the fans on your GPUs spin up a bit when this happens.
- You should be able to SSH into your miner at any time and type miner to monitor the miner’s process. To close the screen (but keep the miner running), press CTRL+A, then CTRL+D.
- If you ever need to start the Claymore miner manually (because you quit out of it, or kill it, etc), simply type ~/miner_launcher.sh
(update 1/15/2018: **IMPORTANT** please read this if your hashrate is lower than expected!)
Output from a single budget RX 470 at stock settings running Claymore’s ETH miner. You should see something like this when connecting to your rig via SSH and running your “miner” alias.
Congratulations—you have your own headless linux ethereum miner!
The next section of this guide covers setup under Windows, and then we’ll take a look at optimizing miner settings for better performance.

A real real fantastic tutorial and overview of the situation. There are always new things happening in hardware or driver or software, but I wished to had this 1-2 years before.
But I want to give some addons:
A normal windows 7 or 10 is about € 35,- / USD 50,- (HP, DELL whatever labeled).
The cost of windows should not be the reason for taking linux.
And yes, the windows driver out of the box and all tweaking and OC is much more easy with windows (for the start).
But think a bit bigger:
1000x Rigs => 1000x Windows Updates on the update day and maybe 1000x problems on same time. You need ActiveDirectory (AD) and much more managing.
If you are once a bit more dedicated to linux (just 2-3%) and you mastered your first little scripts and cronjobs without any gui or desktop, then you will see, feel and like the advantages.
1000x Linux Rig. 1x Test, 2x Test -> Distribute with own little stop all, copy all (or synch) and start all scripting.
And last but not least: On our linux machines we use Genoil with no problems. The undervolting and overclocking of the needed parts was very hard to find out on linux (for me) because never needed such action before on a linux machine. LAMP is more easy for me, because using it since 20 years 😉
And ethminer is creating the DAG on disk? Really? Always?
Never tested around with it again, after the hashrate was 5-10% lower for me on a Ubuntu (CL, not GUI!)
Great informations. Great overview. Great step-by-step.
THANK YOU!
Thank you for this great article on how to min Ether.
I got mine running in one hour. I have a PC with two AMD RX580
the setup so far only see one video card. I have looked on the internet about enabling the second RX580 for mining but I can not find a definitive answer.
I would appreciate if you could give some pointer to run XUBUNTU with two AMD GPU with Claymore miner. Thank you
Dave78701
Just follow this linux guide, it can run from 1 to 12 GPUs with no problem, no more steps nor secret commands, even if you add more cards later, just turn off, plug the new GPU ans restart the rig, when claymore start it autodetect all the GPUs plugged in
I changed the BIOS to GEN3 for PCI slots. I uninstalled and reinstalled AMDgpu-pro 17.x but it is still only see one AMD video

Thank you in advance
Install only 1 GPU first, change PCI-E to gen 1, if everything goes fine, then add the second GPU, rinse ando repeat… Stick to PCI-E gen 1 to assure compatibility, you won’t get any extra benefit from gen 2 nor 3 in cryptomining
Was thinking about your issue, but you don’t mention what motherboard are you using, nor how many GPUs are you trying to install, few motherboards are more than 2 GPU compatible. Have properly powered PCI-E risers? (no more than 2 risers per PSU cable).
Use the drivers install commands as follows:
cd ~/Downloads
wget –referer=http://support.amd.com https://www2.ati.com/drivers/linux/ubuntu/amdgpu-pro-17.10-414273.tar.xz
tar -Jxvf amdgpu-pro-17.10-414273.tar.xz
cd amdgpu-pro-17.10-414273
./amdgpu-pro-install -y
Please post your results
Amazing post, thanks for it.
Question, is there anything else needed?
I ask bacause I tried to check my balance after 4 days in https://etherchain.org/, also in console with “geth console” then “eth.getBalance(eth.coinbase)”, both times was 0.
As I red, the payout comes only when I reach 1ETH.. so it’s gone take sometime, but I want to be sure that it will come. Is there anything else missing at all in the set up?
Again, thanks for the amazing post.
You can check your balance in https://ethermine.org/ only if you are using that pool as described in the guide, you must input your wallet number in the balance page, as you say, only can get your ethereum transfered if you have more than 1 ethereum in pool balance
Hello,
You didn’t say, but I believe you have to be synced on Geth before you can check you Wallet Balance.
To check how much the pool owes you before transferring the balance to your wallet, go to https://ethermine.org/ (if it’s the pool of your choice as in the guide), if you want to veryfy how much ethereum is actually in your wallet, then you check it in https://etherchain.org/ and as RobertMiner wrote, you must first sync your wallet (it takes like half day to be sync)
Hey Guys!
I’ve just picked up 2 x Sapphire RX Vega 64s.
I can’t seem to get the Miner to recognize the cards at all.
Does the Claymore miner not support them yet?
Any feedback / help would be great.
Thankyou!
Did you try Claymore version 9.8? That’s supposed to support Vega cards.
Hey mate.
Yes I did.
I run all my other rigs on Claymore 9.8, with no issues.
This Vega card has absolutely zero response.
I’m going to try switch the motherboard & see if there is a change.
What’s the next best option for mining Ethereum (in terms of a miner?)
Or if anyone else has any feedback / ideas / guidance – would be awesome!
Thanks in advance for the help 🙂
Regards,
Aleks
Has anyone tried the AMD Blockchain driver for Linux? People are saying they are getting better hashrates.
https://bitcointalk.org/index.php?topic=2102129.0
I successfully installed the Blockchain driver with 17.30 following hints on this page: https://bitcointalk.org/index.php?topic=2102129.35
But the same card that gets 26mhs in Windows gets only 19.67 in Linux. Likely because I can’t seem to be able to overclock mem/underclock CPU.
Hello Robert, it’s because under Windows you have the GPU overclock vendors utility, if you ran Claymore under Linux you must mod the GPU BIOS first ti achieve that MH/s
Hey, Sorry too so long to reply.
I am running MSI Z87-GD65 Gaming motherboard with Pentium G3220 Haswell Dual-Core 3.0 GHz LGA 1150. It has 8 Gb RAM.
I forgot to connect the power 8 pins connector to the second GPU, so It is working now but the Hash Rate for both GPU has dropped to 18 Mh/sec, It was running 23 Mh/sec with one GPU so I would expect to have 46Mh/sec with two.
Both GPU are directly connected to the motherboard so it should be reliable without riser
Thank you again for all your pointers
Cheers!
I changed the PCI setting latency to 128 and GEN3 in the BIOS. Now my the two GPU running 46 Mh/sec 🙂
my rig is running well !
Thank you very much for your expertise!
I’m having trouble with the ./mine command.

I have 4x Rx470 running Claymore v.9.0, only for Ethereum mining.
I have observed that their hashrate is slowly decreasing over time.
I remember back 3 months ago they were at 28Mh/s each, now they are at 25Mh/s each (without changing anything on my configuration of course).
Here’s how I run Claymore:
Code:
./ethdcrminer64 -epool eu2.ethermine.org:4444 -ewal -epsw x -mode 1 -tt 68 -allpools 1
I’m running Ubuntu 16.04 – AMD drivers 16.60
Claymore miner is at version 10 now. Might want to update. I had issues until I updated.
Tested Claymore 10 but getting exactly the same results. I’ve seen somewhere that this is happening because of the increasing DAG, are you getting decreasing hashrates as well?
[…] cryptobadger […]
Thanks for this tutorial. I am getting started and now facing a first issue.
When I plug in my 1st GPU (Sapphire Nitro+ RX580 Special Edition), I can’t boot anymore.
Installed xubuntu 16.04 and was loading fine, but after plugging in the GPU I can’t even get into the BIOS when I turn the power on.
I certainly missed something but can’t figure it out.
Mobo is Asrock H81 Pro BTC R2.0
I followed the part 1 guide to the last detail. My rig is completely built the only problem is, it won’t boot. I’ve tried everything – resetting RAM, only one GPU connected, resetting CMOS. It will turn on but the display shows no output. I tried connecting HDMI to mobo and nothing, then I tried connecting HDMI to video card and the display shows ASROCK for like 1 second and goes back to showing nothing.
Other than this, absolutely no problem – CPU spins well, GPU hums calmly. Keyboard light does go on and display does work as I tested it with my mac and it displays perfectly.
Any help would be GREATLY appreciated. At this point I’m just sitting on a huge investment and not able to capital on it.
Thank you!
Hello Al Waters,
Can you SSH into your rig per the instructions found in Step 3?
(Step 3: Install SSH and package updates
At the Xubuntu desktop, press CTRL+ALT+T to open a terminal window.
Install SSH by typing:
sudo apt-get install openssh-server
..With SSH installed, you can unplug the keyboard/mouse/monitor from your miner, and complete the rest of the installation from your desktop computer..)
Your rig might have gone headless due to an incompatibly between earlier versions of Xubuntu and the AMD driver which can be explained in detail in other Q & A postings.
You can operate your rig headless with no issues, except I would consider a different Eth wallet to store your mining coins than what you set up here. It will save you some work exporting keyfiles later.
Good Luck
Miner_launcher.sh is starting , but it is not reigerring mine.sh.
Twice done complete setup , but same issue. all comand are copy paste from your manual .
BTW awesome JOB 🙂
How many days he mining takes until you can see non-zero balance in your wallet?
With RX560 I’m on 12 MH/s mining cca 200 hours and the balance is still zero. I’m checking the wallet balance over https://etherscan.io/
Patas you can see your balance in etherscan until you have completed 1 ether, to see how much fractions of ether you have in the pool check it here: https://ethermine.org/miners/%5BYOUR WALLET ADDRESS] (asuming you choose ethermine as pool)
Thanks a lot. There I can see the fractions of ETH I mined.
To check how much the pool owes you before transferring the balance to your wallet, go to https://ethermine.org/ (if it’s the pool of your choice as in the guide), if you want to veryfy how much ethereum is actually in your wallet, then you check it in https://etherchain.org/ you must first sync your wallet (it takes like half day to be sync)
This is a great guide. A couple of things to note.
I would recommend strongly mining to a cold wallet address and not to the miner’s address as this guide suggests. Make 100% sure you have the private key and the public wallet address for this cold wallet backed up to cold storage. The reason is because most people won’t backup their miner’s private keys properly (which is not mentioned in your guide) and after their rig hard disk fails will lose all their mined ether. Also if their rig gets hacked they will not lose their ether if they are using a cold wallet generated from another system.
The second thing I noticed is the ether pool you noted in here was picky and would not let me mine using the parameters specified here. Something about not using the wallet address in the command or something like that so I chose nanopool which seems to work without complaining.
Many of the problems in this forum are attributed to the behavior of the BIOS/Ubuntu when you remove the mouse and keyboard. Before you put your miner in a basement with no keyboard and mouse try booting it a couple of times without the keyboard and mouse but with the monitor hooked up so you can address any errors in the bios or OS pertaining to the lack of a KB and mouse.
I also noticed this on hardware; That you want to install Ubuntu WITHOUT the mining cards in the system (just the plain old crappy video card you plan to use for Ubuntu should be inserted during Ubuntu install). Once Ubuntu is installed and stable, do a sudo shutdown now and insert your mining cards, boot up, then follow this guide to install the mining card drivers. This worked for me and was the only way mine would install and work properly.
Is it possible to use the same wallet for more than one mining rig?
In case another computer is available with GPUs which cannot be installed into the original (first) Linux computer because of lack of PCI-e slots there.
If so is it enough only copy content of user’s ~/.ethereum/ directory to the second Linux machine and run “…Miner02 …” like
export GPU_MAX_ALLOC_PERCENT=100
./ethdcrminer64 -epool us1.ethermine.org:4444 -ewal YOUR_WALLET_ADDRESS.Miner02 -epsw x -mode 1 -tt 68 -allpools 1
???
Yes, you can mine to the same wallet address from multiple rigs/computers. You can use the same scripts, assuming you’re running the same hardware, and just change the friendly machine name (eg: Miner01, Miner02, etc – like you’ve specified) on each computer.
Hi
Awesome guide. My rig is running smoothly and I can access it with Putty, but I am not sure how to access it remotely over the internet. I have forwarded the port as per your guide but that’s as far as I get.
Please help?
If you’ve opened a port in your firewall/router, you should be able to access your rig from anywhere. Just make sure that you’re trying to connect via putty using your public IP address (which you can easily look up using this handy site).
If you’ve opened the port and still can’t access your rig over the internet, it’s possible that your ISP is blocking inbound requests – although that’s relatively rare. If that’s the case, there isn’t much you can do about it, unfortunately.
Thanks, I will try that. Did not think to use Putty for that.
If you open up your rig to the Internet, be careful to ensure it’s read-only.
See -mport and -mpsw options for Claymore.
Hi, thanks for sharing all of your hard work. It’s folks like you who make the Internet good!
I know you’re being bombarded with questions, but if you get a chance, any advice would be awesome!
I have 6 MSI RX580’s (8GB Armor OC, Hynix memory) on an Asus Z270 Gaming Carbon board. I’ve followed your guide and updated all the cards’ BIOS with core clock 1135, mem clock 2150, at 950mv. And also changed the memory timing values accordingly.
Before modding, the cards were running at 20mh/s and after doing the above they run at 24.5mh/s. And now Claymore doesn’t seem to like it. Sometimes it starts then hangs after a few minutes and I get the “incorrect share” warning a few times, suggesting I’ve overclocked the cards too much.
I have at least 16GB virtual memory and GPU_MAX_ALLOC_PERCENT is set at 100.
Any idea why the hashrate is low? I’ve only got teamviewer access at the moment so I can’t re-flash the cards but I did try adding different clock speeds in the batch file, but it doesn’t seem to make any difference.
Typically, Claymore will run for a few minutes, watchdog will state GPU X hangs in OpenCL call, exit. Then it will restart and hang just after recognising the cards again (at POOL/SOLO version).
watchdog will state GPU X hangs in OpenCL call.
Check the specific gpu, change riser!
You need to do a little debuging on it:
run claymore and in another terminal window tail -f /usr/local/claymoreXX/xx-yyy-zzz.txt claymore is making logs for the miner, if you trace the logs then is clear what gpu has a problem.
After the haning disable the problematic gpu and run the miner, to disable the specific gpu u need to put the following parmater:
-di 01235 then gpu 4 is disbaled by the miner. If everything runs well without the problematic gpu then it is only th eone gpu with problem and is not a moding issue.
thanks ck. If I disable the GPU, then another hangs. Disable that, then another hangs. So I guess I’ll have to reset the BIOS on them when I have access. And then try Claymore’s integrated clock speed options alone. Seems odd as the mods are well within limits.
It turns out is was a modding issue. I reset the GPU BIOSes back to stock settings and Claymore runs well. Although of course, now I only get 20mh/s per card and 1100 watts at the wall, so not profitable.
Any suggestions? Just keep tweaking the values up until it breaks then drop slightly is the obvious answer, but any idea why the hashrates are so poor?
AI: the low hashrate could be because of the Linux/drivers hashdrop issue, it can be solved changing your Linux kernel to the optimized for mining, you can find more details here:
https://www.reddit.com/r/EtherMining/comments/6wsf7o/new_amd_blockchain_optimized_drivers_availible/
Also be shure to use the ATI 17.10 driver version, and the low hashrate should be solved. Talking about the stability issue, as you say the BIOS mod must be done step by step, and remember not all GPUs can be overclocked with exact same parameters, even same brand and model varies in overclock capabilities because silicon lottery
i have a rig window with working 5 gpu properly but ubuntu only 4 working why???/
I guess you are talking about one computer and you have multiboot into Windows or Ubuntu.
On Ubuntu try command ‘lspci’ You will see all graphics cards that system recognized.
You can also check startup log with command ‘dmesg’ Maybe you can see error/reason there why the last card was not recognized or is ignored.
I have a 6 GPU rig on Ubuntu 16.04, all recognised. I found I had to set PCI to GEN 2 in the BIOS to detect 5 cards, then GEN 3 to detect all six. Once all 6 are detected and listed using the lspci command, set them back to Auto in the BIOS otherwise you get zero hashrates in Claymore
Ok I followed all the steps and when I type ./mine.sh I get the following error: ./ethdcrminer64: 1: ./ethdcrminer64: Syntax error: Unterminated quoted string
I think this is in the mine.sh file –
A couple of issues
1- instructions says put Ox in front of wallet address so I did but I deleted this symbols from the address{} is this correct or should they be in there if so I assume it will look something like {OxWalletAddress} ?
Please help!
Thank you
Hi Shelley, it should be a zero: 0x
Hello Shelley, I think all the problem is in your sintaxis, is not “Ox” (letter O), is “0x” (number zero), and as you write without the “{}”
