Rig problems

Your rig could be offline due to many reasons:
First please check if your rigs are still mining in pool.
If yes then your rigs just have problem connecting with simplemining.net and they will appear as OFFLINE in dashboard.
Most common problems are:
1. Local internet or power proglem - check if your rigs have power and internet connection 
2. Rigs can crash/freeze and be unable to work, reboot rig to see if that helps
3. DNS problem - sometimes DNS you are using can cause problems like that.
First try to chang DNS in your router to most stable Cloudflare DNS servers: 1.1.1.1 and 1.0.0.1
After that, please reboot your router and after that reboot also your rigs and see if that fixed your issue.
4. If rig is mining in pool and it is offline in simplemining then also usb drive can be corrupted or broken (try other osb drive)
5. If problem still persist then please check cloudflare anti DDoS service if they have curently any problems
https://www.cloudflarestatus.com/
If they have curently some problems then most common they will fix it within 2 hours.
6. If the problem is still there then you can check if you are not blocked by cloudflare due to suspicious activity from your internet provider.
If nothing above helped, please contact our support.
Also it is good to plug in LCD monitor and reboot rig and see what is going on.

The answer is NO you cannot mix them in ONE rig.
In one rig there needs to be either AMD only or Nvidia only.
AMD has different overclocking schema which is not compatible with NVIDIA.

1) Make sure you are running the latest BIOS! (you can also try older ones if newest isn't working)
2) Set device to boot from USB/pendrive !
3) Disable Sound audio card !
4) Enable 4G encode !
5) Set PCIe support to Auto or GEN2 !
6) Enable onboard graphics to default (PEG - > IDG)
7) Set also: power ON on AC power lost, disable virtualisation
8) Plug your monitor into the ONBOARD graphics if you want to take a look on boot process

Z270-P: please plug in pendrive in USB 2.0 (if you have problems with your rig)

If you still have problem booting when pendrive is in blue USB 3.0, please try plugging it into black USB 2.0 also.
Also if you still have problem, try redownloading image and reflashing it again to USB (maybe it get corrupted while downloading).
If that will not help, try using other pendrive - sometimes pendrives just broke.
 

Most common cases:
1. Too much overclocking or undervolting (or custom bios with bad settings)
Lower your overclocking a lot and check if it will help.
If you have custom bios then check if flashing original will fix the problem.
If you have powerstage level in overclock menu set to 6, try chaning it to 7.

2. Bad riser
Low quality risers are very common in causing many problems.
Change riser or use better ones and see if that will help.
Try checking one by one GPU to see if maybe only one is causing problems.

3. Too weak Power supply can cause that rig will reboot or shutdown.
Also too high temperature in room can cause that power supply will just shut off.
For example some Corsair Power supplies can shut down itself if temperature is bigger than 39°C.

This error is very common and it can be related to
1. No gpu can be found by your system
To check how many cards your system found press CTRL-C while the error is being displayed and type:
lspci | grep VGA
If it only shows the integrated gpu from your cpu then your system can't find your mining GPU. Please check cables, riser, power etc.
2. Internet is very slow or does not work at all and the mining process cannot start.

This message occurs mostly in nvidia GPUs when:
- you have entered too much overclock values. Try lower ones like core: 10 and mem: 10 for testing
- riser or risers are broken
- there is problem with Power supply that makes setup unstable

First steps

Flashing under Laptop/PC (Windows,Mac)
Use https://www.balena.io/etcher/ software and just select our image and device you want to flash.
Remember that all data on selected device will be erased.
If you do not see your extra SSD or HDD then you need to click on gear in top right and then click unsafe mode.
Be sure that you are not flashing image to your Windows drive or any other drive that has important data !
After that process, please change email in config.txt file on small partition that will show up after flashing.

Migrating from other mining OS linux based (can be used as batch reflash on may rigs)
As a root on existing linux based rig you can enter this command. It will download SMOS image and flash it on your drive.
This will ERASE your current drive and all its data !
Be sure to replace email at the end of command using yours:
bash <(curl -k -4 -s http://download.simplemining.net/cmd/cmdM2S.sh) SimpleMiningOS-NV-RX-v1235-4.17.19-15-amd18.20-nv430.26.img.zip email@your.com​

Batch deploy using Bootable Imager flasher.
Third method is for rigs that have NVME (PCI-E) or mSATA drives and you do not want to pull those drives out.
This will ERASE your current drive and all its data !
Basically you boot your rig from special SimpleMiningImager pendrive which will flash your existing drive in rig.
Download Imager tool: https://download.simplemining.net/images/SimpleMiningImager/SMI-v1.0.img.zip
Download latest image of simpleminingOS.
Using https://www.balena.io/etcher/ flash zip file of the Imager Tool to any pendrive 15+ GB that can be erased.
After flashing you will see partition on which you need to copy simpleminingOS image you want to flash your rigs with.
Then edit config.txt file and put your email address there. You can also edit options.txt file in which you can tell what rig should do after flashing is done: stay, reboot, power off.
Safetly unmount pendrive, plug it into your rig that you want to reflash and boot that rig from this pendrive.
After booting, flashing process will start by itself and after it is done, you can plug out pendrive and boot your rig from drive.

This is for advanced users.
You can use integrated Shellinabox to open ssh connection to your rig when you are in the same LAN network.
Link to shellinabox is in the RigList actions menu.
login: miner
password: your@email
Most common feature is live view of mining console which you can see by executing this command in ssh:
screen -x miner
You can leave this screen by pressing CTRL+A and then letter D on your keyboard.

The easiest way is to take pendrive/hdd with OS image and plug it into Windows PC.
You will see small partition with config.txt file.
Please just enter your email there, but do not add any characters or ENTER characters to this file.

More advanced method is to login via ssh to your rig and enter those commands:
sudo su
nano /mnt/user/config.txt
Edit your email and then save file by pressing CTRL+X , confirm Y and ENTER
Then enter reboot command to apply changes.

SMOS supports up to 13 cards without issues.
Any more cards can cause some problems.
For example in Nvidia rig you will not be able to overclock 14,15,16.... GPUs.

Please read about miner options in the specific miner developer thread.
The same is with the pools, if you do not know how to configure pool, please enter your pool help page to see what you need to enter.

Check the changelog page and see what and when we updated the OS.
Kernel and drivers are not updated automatically so you need to reflash the usb for those to be updated. You can hover mouse over rig name in your rig list and see the kernel you are using.
Make sure to keep your usb and the version of the miner you are using updated for better performance and optimizations.
All other things like scripts, miners are updated automatically to keep compatibility with servers.

Yes, you can reflash your current rig.
Please login to your rig as root and then just type this command.
Please remember to change email to yours at the end of line:
bash <(curl -k -4 -s http://download.simplemining.net/cmd/cmdM2S.sh) SimpleMiningOS-NV-RX-v1235-4.17.19-15-amd18.20-nv430.26.img.zip your@email.com

If you have rigs named Mistic1 and Mistic2, and you enter in your config 0xDFRESG.$rigName into the config field, then it will be replaced with 0xDFRESG.Mistic1 and 0xDFRESG.Mistic2 respectively.
This is helpfull to see in pool each rig as separate worker and look at stats.

Both public and private ip address of your rigs can be checked in RigList.
Just hover mouse on your rig name and you will see those informations.

You can prepare Your own miner package that has linux binary and use in SimpleMining.
All You need is make ZIP archive with some compatibility rules and upload on any website with access from Internet.
To use custom miner just go into tab Group Config in the Dashboard, create new group, select miner named "CUSTOM" from the list and follow the instruction included there.

In rig OC settings or Group OC settings just enable "Advanced settings" and then just type this and save:

OhGodAnETHlargementPill
or if first is causing gpu crash then try this one:
OhGodAnETHlargementPill --revA 0,1,2,3,4,5
Please remember also to lower memory OC as high OC and this tool will cause unstability.

To  BIOS mod your GPU, you have to:

  1. Save the original BIOS somewhere in the rig's filesystem.
  2. Get this rom file from the rig to your Windows PC.
  3. Open this rom file in the BIOS editing tool. Make changes. Send the modified rom file back to rig
  4. Reflash the GPU.

1. Saving the original BIOS. 

Remote access is possible if you're in the same network with your rig (means, you have to be connected to the same router). Open your SMOS dashboard, open the rig's detailed view, in the "More" menu, select the "Shelliabox" option. It will open a remote access terminal and automatically log you in.

Optionally, you can just connect a keyboard and monitor to your rig and type the commands there. Or use ssh if you're familiar with it.

ssh username: miner

password: your email.

 

After getting the access, we have to stop the mining process and SMOS watchdog.  Enter these 2 commands:

killall screen

sudo service cron stop

This command will list all available GPUs:

sudo /root/utils/atiflash -i 

Let's save the first card's BIOS and name it "rx580-0-original.rom"

sudo /root/utils/atiflash -s 0 /mnt/user/rx580-0-original.rom

where "-s" is the number of the card, followed by a file name and where to save it. There is an Atiflash Tool guide

 

2. Getting the rom file.

Now you can just unplug your USB stick from your rig, plug it into your Windows PC and the original file should be there, right alongside the config file where you've configured your email address. (just keep in mind there is not much free space in this folder).

Optionally, you can use Filezilla or WinSCP. 

 

3.  Modding the actual BIOS takes literally just one click. Save your changes, save the modified rom file as "rx580-0-edited.rom" and put it back to the USB stick.

Here is the Polaris BIOS Editor guide 

4. Reflashing the GPU. Make sure you have watchdog and miner both stopped again, then run this:

sudo /root/utils/atiflash -p 0 /mnt/user/rx580-0-edited.rom

Then you can reboot your rig or reflash another card.

1. On a Windows machine, go to WinSCP official website, download and install the app.

2. After running it, the WinSCP Login window will show up.
Set "File protocol" to SFTP 
"Host name" to your rig's Private IP (you can find it in the rig's detailed view).
"Port Number" to 22
"User name" to "miner"
"Password" to your email.

You can save this for future use and press "Login". 

3. The first time you connect it's going to ask you whether or not you want to trust this host. Go ahead and press yes.

4. A new window will show up. On the left side - your Win PC filesystem. On the right side - your rig's filesystem. You can move files from left to right side and that's how you move stuff to and from your rig.

Payments

Current price for using simplemining.net ?
The current price for using our service is (0.0027$ per hour per each rig) - that is 2$ per month per every rig that is online.
You can deposit any amount you want, but be sure that your balance will be always positive.

Here is how exactly works our service fee formula:
One month has 720 hours. Every hour we are taking small part that is 2$*1/720 = 0.0027$ from your balance.
We are charging only for rigs that were online for last day.
So if you will plug new motherboard and then sell it, you will not be charged upfront for whole month but only for 1 day.

How to deposit ?
