If you are on Windows, check to see if Compute mode is turned on. Also check if Windows update updated the drivers by itself. You can disable driver updates in gpedit to keep Windows Update from modifying your drivers.

gpedit ==> Navigate to: Computer Configuration ==> Administrative Templates ==> Windows Components ==> Windows Update and set 'Do not include drivers with Windows Update' to enabled.

If all you care is about mining Ethash then the Bitmain E3 is certainly an option, however the E3 has no real advantage over GPU rigs other than a slightly lower cost/MH, which is negated by the fact ASIC's have almost no resale value. A 6 x RX 580's rig with a simple 'one click' bios mod will give you ~185 MH/s on Ethash for ~750 W with an undervolt.

Now that the price on GPU's has finally come down, you could buy 6 of these Sapphire Nitro+ RX 580 4GB cards at $209 each for $1260 together with another ~$300-400 for a motherboard, CPU, RAM, PSU and risers that would give you the same output as a Bitmain E3 on Ethash with the option to mine any other GPU minable coins, a better warranty AND be able to resell all the components to gamers.

To me the E3 is only a better option for industrial miner setups looking to fill warehouses with miners. For a home miner you are better off setting up a GPU rig to mine Ethash.

Good guide with all the steps for getting started mining ETH on Windows with both AMD and Nvidia.

I have Windows v1709 with the current updates and the GeForce 399.07 WHQL drivers with Claymore v11.9 running very stable. Don't know if the problem is with the Claymore miner or the drivers, but there is an issue causing the NVIDIA drivers to crash after a few hours when mining on Windows 1803.

Use Rufus to copy a Windows 1709 ISO to a USB flash drive and do a clean install of Windows by selecting the UEFI setup from the boot Bios boot menu with only a single GPU in the primary x16 PCI-E slot. After the install is finished, on the first logon disable Windows feature updates in gpedit. On Windows 10 Pro you can set a Group Policy to defer feature updates until they have been targeted for business deployment, which is about 4 months after the public release, or you can also defer feature updates for up to 365 days. This way you still get the security updates.

gpedit ==> Computer Configuration ==> Administrative Templates ==> Windows Components ==> Windows Updates ==> Windows Update for Business ==> Select when Preview Builds and Feature Updates are Received ==> Set to 'enabled' and  in the drop down select 'Semi-Annual Channel'. Underneath that option set 'After a Preview Build or Feature Update is released, defer receiving it for this many days:' to 365.

Then run Windows Update to get the latest updates and reboot. Go back in to gpedit and disable driver updates to keep Windows Update from modifying your drivers.

gpedit ==> Navigate to: Computer Configuration ==> Administrative Templates ==> Windows Components ==> Windows Update and set 'Do not include drivers with Windows Update' to enabled.

Shutdown to install the rest of the GPU's. Afterwards download the latest driver for your GPU's and then run the GPU driver setup. For some reason the latest DDU is not working for me so I did a clean install option from the driver installer when installing the latest NVIDIA driver.

I also go in to Windows Apps from the settings to uninstall all the extra Windows crapware and disable all the Windows spyware in the Privacy settings.

Most ETH pools use a fixed share difficulty to prevent overloading the stratum servers with too many requests. e.g. Ethermine uses 4000MH and Nanopool uses 10000MH. Which means on Ethermine your miner should find roughly 2.5x more shares for the same hashrate and timeframe than on Nanopool. But since the weight of shares on Ethermine are worth 2.5x less than the shares on Nanopool, the amount of ETH you receive is the same, based on your contribution to the round.

The string you posted has an extra 1 after -pool. It should be


The rest is correct. If it's still not connecting, check your Windows Firewall rules.

Yes. The Adrenaline drivers work for all GCN architecture cards, from Southern Islands cards through Vega.

Correlation isn't causation. I have 3 mining rigs that over the past year have been shut down for maintenance and/or rearranging several times, including for over 10 days and have yet to have blown a capacitor. I also have a Dell XPS 700 from 2006 that I mined with for months on and off back in 2014 and I still use it as a test bench. Just cause your friend blew a capacitor when he turned the rig back on after an extended time off doesn't mean that's what caused it to go. More likely it was some other reason or was defective.

Just run an administrator command prompt and ping the stratum server. e.g.


Anything <100 ms is good.

I'm running 13 RX 480/580 8GB on Windows v1709 with the Adrenaline v18.71 drivers on a ASRock H110 Pro BTC+ moterboard with an i3 CPU, 8GB RAM and a 78 GB vitrual memory set. Windows does start to run a bit laggy when running more than 10 GPU's, but it's not too bad and otherwise runs stable.

Do a clean install of Windows 1709 with only a single GPU in the primary x16 PCI-E slot. After the install is finished, on the first logon disable Windows feature updates in gpedit. On Windows 10 Pro you can set a Group Policy to defer feature updates until they have been targeted for business deployment, which is about 4 months after the public release, or you can also defer feature updates for up to 365 days. This way you still get the security updates.

gpedit ==> Navigate to: Computer Configuration ==> Administrative Templates ==> Windows Components ==> Windows Update and set 'Do not include drivers with Windows Update' to enabled.

Download the latest driver for your GPU's and run DDU in safe mode to remove the Windows installed driver and disable automatic driver installation when prompted by DDU. Shutdown, install the rest of the GPU's and then run the GPU driver setup. After the driver setup is finished (it will take >20 minutes with 13 cards). If you have any RX 570 or 480 cards with a modded Bios you will also need to run the pixel patcher to disable the driver signature check.

I also go in to Windows Apps from the settings to uninstall all the extra Windows crapware and disable all the Windows spyware in the Privacy settings.

Te pill works great on my rig with a 1070, 1080 and a 1080 Ti and the latest Nvidia drivers. No reason why the pill would cause instability with mixed cards since it only affects 1080 and the 1080 Ti. If the miner is crashing it's probably from too much overclock.

You should specify the main ETH pool to mine at with the -epool parameter e.g. -epool ssl://eu1.ethermine.org:5555. Either in a config.txt file or directly in the batch file. epools.txt is the ETH failover pools file for the miner to switch to whenever the main pool goes down and dpools.txt is the secondary coin failover pools for when you are dual mining.

If you want to use different -epool pools as the main ETH pools, you can create different config files with the -epool to use and specify a config file name in the batch file when staring the miner.

e.g. start_claymore_config1.bat

@ECHO off
CLS
COLOR 3F
TITLE %~nx0
CD "C:\Miners\Claymore-latest"
EthDcrMiner64.exe Claymore\config1.txt <-------- This has first main -epool pool

--------------------------------

e.g. start_claymore_config2.bat

@ECHO off
CLS
COLOR 3F
TITLE %~nx0
CD "C:\Miners\Claymore-latest"
EthDcrMiner64.exe Claymore\config2.txt <-------- This has second main -epool pool

etc.

You can also specify different failover epools.txt files with the -epoolsfile parameter in the config file or batch file e.g -epoolsfile Claymore\epoolsfile1.txt, -epoolsfile Claymore\epoolsfile2.txt, etc.

In Claymore you set the main ETH pool with the -epool parameter in the .bat file or in a config.txt file.  If you have different pools you use, you can specify different configuration file names with the -epool to use in the .bat file you use to launch the miner.

You should be able to rename the folder with the current version in the miner folder on ethOS. Then create a new folder with the same name, add the v11.9 files and run sudo chmod +x on ethdcrminer64 to make it executable.

Stale shares are shares for a block submitted after the next block is already being mined. Its result from network latency and fast block times and has nothing to do with memory errors or overclocking. Too much overclocking can definetlly cause memory errors and invalid/rejected shares though. Some of my Powercolor 4GB Red Dragon RX 570's run stable at 29.5-30.5 MH/s with a 1150 MHz core and 2075 MHz memory clock. I do have some that will only run at 1950-1975 MHz memory overclock at ~28.5 MH/s.

Try SD Formatter it's the official utility of the SD Association and the best way to format a SD card. It's restored corrupt drives for me.

For the US ethermine server you need to use the us1 for the east coast or us2 server for the west coast, whichever is closer AND the ssl stratum port 5555.

-epool stratum+ssl://us1.ethermine.org:5555

or

-epool stratum+ssl://us2.ethermine.org:5555

Everything else is the same.

If you have a computer with a modern graphics card you can start mining with the hardware you have at night whenever you're not using it to get familiar. Basically you need to setup a wallet for the coin you want to mine to get the address where to get paid, download a miner program for the algorithm used by the coin you want to mine, choose a pool for the coin you want to mine and configure the miner with your wallet address and/or your pool worker info.

There are lots of websites and Youtube videos on how to get started. Just google 'How to mine XXXXXXX'. BBT's Youtube has many videos on how to setup and configure a mining rig from scratch. He also has a multi-miner that he updates regularly that makes it easy to mine different coins.
