Fast start

To start as quickly as possible it will be enough:

• Download the program archive.
• Extract it to any convenient location.
• Change the wallet address in the .bat file to your own.

In the program archive, you will find ready-made examples for Ergo, Ethereum, ZIL, and other coins, a configuration file, and instructions in Russian.

Quick start examples

The easiest way to start using SRBMiner is to configure the program from the command line. Simply create/edit a ready-made .bat file.

Commands to run (on Windows):

SRBMiner-MULTI.exe --disable-cpu --algorithm autolykos2 --pool ergo.herominers.com:10250!ergo-eu.leafpool.com:1111!pool.coinfoundry.org:3036!pool.woolypooly.com:3100 --wallet 9gj5rYtg1sGwdvoXGJswrSfPBXiXJgmyjZVEQ9p5fvZrCAfu6zT --gpu-boost 3 pause

How to configure .bat file

To start mining, we need to create or edit a .bat file. In it, specify the following commands:

• SRBMiner-MULTI.exe – command to launch the SRBMiner application.
• --disable-cpu – disable mining on the CPU.
• --algorithm autolykos2 – specify the mining algorithm.
• --pool ergo.herominers.com:10250 – specify the pool address and port.
• --wallet 9gj5rYtg1sGwdvoXGJswrSfPBXiXJgmyjZVEQ9p5fvZrCAfu6zT – specify the coin wallet. You can obtain the wallet either from an exchange or set up a cold wallet.
• --gpu-boost 3 – used to increase the hash rate of your graphics processor. This parameter is activated only when the miner is launched with administrator privileges.

Let’s see what we got in the batch file:

SRBMiner-MULTI.exe --disable-cpu --algorithm autolykos2 --pool ergo.herominers.com:10250!ergo-eu.leafpool.com:1111!pool.coinfoundry.org:3036!pool.woolypooly.com:3100 --wallet 9gj5rYtg1sGwdvoXGJswrSfPBXiXJgmyjZVEQ9p5fvZrCAfu6zT --gpu-boost 3 pause

The program is launched as usual, by double-clicking on the file with the .bat extension

Setting up configuration files

In the archive with the program you will find examples of configuration files, configured .bat files and instructions in Russian.

Configuration options in the config.txt file

• "algorithm" Specify the algorithm.
• "intensity" Specify the intensity (1-31). If set to 0, the miner will attempt to find the best settings (intensity, worksize, threads).
• "raw_intensity" Specify the number of global threads. Use this if you want to precisely configure intensity.
• "worksize" Specify the size of the local work group.
• "threads" Specify the number of GPU threads to use.
• "giveup_limit" Specify the number of times to attempt to connect to the pool before switching to the next pool from the pool.txt file. If set to 0, the miner will terminate and not retry the connection.
• "timeout" Specify the time when the connection to the pool is considered expired.
• "retry_time" Specify the time to wait before attempting to reconnect to the pool.
• "reboot_script_gpu_watchdog" Specify the filename for the script in the miner directory. If set, it disables the built-in miner restart procedure on GPU failure and instead runs the script you specify.
• "main_pool_reconnect" Specify the time (minimum 3 minutes or 180 seconds) interval for attempting to reconnect to the main pool. Default is 10 minutes.
• "target_temperature" Specify the temperature from 0 to 99. The miner will attempt to maintain the specified temperature on all detected GPUs (ADL must be enabled, works only on cards supporting OverdriveN).
• "shutdown_temperature" Specify the temperature from 0 to 100. If this temperature is reached, the miner will shut down the system (ADL must be enabled).
• "off_temperature" Specify the temperature in degrees Celsius. If the GPU reaches this value, it will be turned off. After reaching -15, the card is automatically turned on again.
• "tweak_profile" Specify the profile (0-10) that applies settings to the GPUs, potentially increasing the hash rate. 0 – no tweaks, 10 – max. If you add an “L” after the number, it will use low settings (e.g., “4L”).

Video card configuration in the config.txt file

• "id" Specify the identifier of the GPU. You can find it using the –list-devices parameter.
• "intensity" Specify the intensity (1-31). If set to 0, the miner will attempt to find the best settings (intensity, worksize, threads).
• "raw_intensity" Specify the number of global threads. Use this if you want to precisely configure intensity.
• "worksize" Specify the size of the local work group.
• "threads" Specify the number of GPU threads to use.
• "tweak_profile" Specify the profile (0-10) that applies settings to the GPUs, potentially increasing the hash rate. 0 – no tweaks, 10 – max. If you add an “L” after the number, it will use low settings (e.g., “4L”).
• "target_temperature" Specify the temperature from 0 to 99. The miner will attempt to maintain the specified temperature on all detected GPUs (ADL must be enabled, works only on cards supporting OverdriveN).

Example:

"gpu_conf" : 
[ 
	{ "id" : 0, "intensity" : 20, "worksize" : 256, "threads" : 1},
	{ "id" : 1, "intensity" : 20, "worksize" : 256, "threads" : 1},
	{ "id" : 2, "intensity" : 15, "worksize" : 64 , "threads" : 2},
	{ "id" : 3, "intensity" : 15, "worksize" : 64 , "threads" : 2}
]

Installation of mining on the processor

If you do not specify the parameters --cpu-threads or --cpu-affinity, the miner will attempt to automatically determine the optimal settings for your system. However, sometimes automatic configuration may not lead to optimal results, so you will need to experiment to find them. It is necessary to set the number of threads (--cpu-threads) and bind them to the corresponding processor using the --cpu-affinity command.

Examples

PROCESSOR WITH 4 CORES / 8 THREADS:

1. Use 4 threads, 1 on each core: --cpu-threads 4 --cpu-affinity 0x55
2. Use 8 threads, 2 on each core: --cpu-threads 8 --cpu-affinity 0xFF

PROCESSOR WITH 6 CORES / 12 THREADS:

1. Use 6 threads, 1 on each core: --cpu-threads 6 --cpu-affinity 0x555
2. Use 12 threads, 2 on each core: --cpu-threads 12 --cpu-affinity 0xFFF

Algorithm switching capabilities

The miner supports two types of algorithm switching:

• User-defined algorithm in the pools configuration file (pools.txt).
• Algorithm switch, initiated on the pool side.

To enable the algorithm switching capability, rename the file ‘algorithms_example.txt‘ to ‘algorithms.txt.‘

1. The user determines in the pool configuration file which algorithm the pool uses.

Pools for multiple coins/algorithms can be defined in the same configuration file, and when manual switching/automatic switching in case of pool failure occurs, the miner will restart with settings for the next pool.

Example:

pools.txt:

{
"pools" :
[ 
	{
		"pool" : "loki.herominers.com:10111", 
		"wallet" : "LWC57bMh2uvQX62DT9eLkr2JvsTbeGKrcbwocNk6nAD2DXQsy4p6CJMV8zze6SYnzo2XHsdsmaDaP8Rc6JceP4WSTkRnjJF", 
		"password" : "x",
		"algorithm": "randomxl"
	},
	{
		"pool" : "xmr-eu1.nanopool.org:14444", 
		"wallet" : "4A5hJyu2FvuM2azexYssHW2odrNCNWVqLLmzCowrA57xGJLNufXfzVgcMpAy3YWpzZSAPALhVH4Ed7xo6RZYyw2bUtbm12g", 
		"password" : "x",
		"algorithm": "randomx"
	}
]
}

The miner will start mining with the randomxl algorithm. If the user manually changes the pool or a switch occurs due to a failure to the next pool, SRBMiner-MULTI will connect to the next pool (in this example, nanopool) using the configuration settings for the randomx algorithm, which are read from the ‘algorithms.txt’ file.

2. Pools such as MoneroOcean can initiate automatic algorithm switching based on profitability.

Example:

There is already a pool configuration file for MoneroOcean included with SRBMiner-MULTI. You can find it in the folder Pools\pools-monero-ocean.txt. Please update the wallet address to your own.

If the algorithm is supported in SRBMiner-MULTI and also in MoneroOcean, you can use it for algorithm switching. If you don’t want to include every algorithm supported by the miner in the algorithm switching process, you need to edit the algorithms.txt file according to your needs.

Algorithms.txt file:

Here, you define individual settings for each algorithm.

Enable the algorithms that will be available in the algorithm switching process.

Commands:

• “algorithm“ Algorithm name [Run the miner with the command --list-algorithms to see available options].
• “config“ Path to the configuration file to be used for this algorithm.
• “startup_script“ Path to the startup script you want to execute when launching the miner.
• “hashrate“ Your system’s hashrate for this algorithm. Used only with the algorithm switch on the pool side.

Example:

{
"algorithms" :
[
	{
		"algorithm" : "randomx",
		"config" : "Config\\config-randomx.txt",
		"startup_script": "",
		"hashrate" : 1400
	},
	{
		"algorithm" : "randomxl",
		"config" : "Config\\config-randomxl.txt",
		"startup_script": "",
		"hashrate" : 1450
	}
]
}

Setting up video card optimization profiles

If you have VEGA56/64/FE/VII graphics cards installed, I recommend using the tweak_profile feature as it has the potential to increase your hash rate on certain algorithms!

For RX series cards, the ‘tweak_profile‘ option can also bring additional hash rate to your flashed graphics cards.

It is also possible to use this option with graphics cards operating on standard BIOS, but the performance will be significantly lower compared to modern BIOS.

Please carefully review this VERY IMPORTANT information:

• To launch the miner with administrative privileges, follow these steps: right-click on the SRBMiner-MULTI.exe file, select “Properties,” go to the “Compatibility” section, check the box “Run this program as an administrator,” and then click “OK.”
• Please be patient when searching for optimal settings for your graphics cards or farms. This process may take some time. Always verify the settings for each card sequentially.
• If you encounter issues such as invalid shares or calculation errors, it may indicate that the current profile is not suitable for your graphics card. In such cases, it is recommended to reduce intensity or lower the frequency of your video memory.

To use in the configuration file, apply the “tweak_profile” option located at the top of the configuration to use the same profile for all cards or in the “gpu_conf” section to set different profiles for each card individually.

Not all cards can handle the same profile, so you need to find a suitable profile for each card in your arsenal.

Tweak level settings:

• 0 – No changes, use your original settings.
• 1 – Light adjustment.
• 2 – Higher.
• 3 – Even higher.
• 4 – Even higher.
• 10 – Maximum adjustment.

Each profile also has weaker (lower) settings. To use a profile with weaker settings, add an “L” after the profile number.

When using the gpu setting in the batch file, it would look like this, for example: –gpu-tweak-profile 3,4,4L,5L

If you are using a configuration file, you should enclose the value in quotes if you want to use an “L” profile. Example: “5L”

The simplest way to apply a tweak profile is to use the + or – keys on the keyboard while the miner is running.

Example batch file configuration [4 cards]:

• GPU 0 uses profile 3
• GPU 1 uses a lower profile 4
• GPU 2 uses a lower profile 4
• GPU 3 uses profile 5

SRBMiner-MULTI.exe --algorithm keccak --gpu-id 0,1,2,3 --gpu-intensity 20,23,23,24 --gpu-worksize 64,64,64,256 --gpu-threads 1,1,1,2 --gpu-tweak-profile 3,4L,4L,5 --pool your-pool-here --wallet ваш_кошелек

Same example as above, using the config file setting:

{
"algorithm" : "keccak",
"intensity" : 0,
"gpu_conf" : 
[ 
	{ 
	  "id" : 0, 
	  "intensity" : 20,
	  "worksize" : 64,
	  "threads" : 1,
	  "tweak_profile" : 3
	},
	{ 
	  "id" : 1, 
	  "intensity" : 23,
	  "worksize" : 64,
	  "threads" : 1,
	  "tweak_profile" : "4L"
	},
	{ 
	  "id" : 2, 
	  "intensity" : 23,
	  "worksize" : 64,
	  "threads" : 1,
	  "tweak_profile" : "4L"
	},
	{ 
	  "id" : 3, 
	  "intensity" : 24,
	  "worksize" : 256,
	  "threads" : 2,
	  "tweak_profile" : 5
	}
]
}

Setting the background mode

Background mode implies that the miner will operate without displaying a console window. Both CPU and GPU miners can operate in the background.

If you wish to stop or disable a miner running in the background, you can find the SRBMiner-MULTI process in the Task Manager.

Example:

Initiate CPU mining in the background mode (without a console window) using 3 CPU threads.

SRBMiner-MULTI.exe --algorithm k12 --pool your-pool-here --wallet ВАШ_КОШЕЛЕК --cpu-threads 3 --disable-gpu --background

Examples of using

1. Disable mining on the processor, use only mining on video cards

SRBMiner-MULTI.exe --algorithm keccak --pool your-pool-here --wallet your-wallet-here --disable-cpu

2. Run the miner in the background without a console window, with the API enabled on port 17644 (http://127.0.0.1:17644)

SRBMiner-MULTI.exe --algorithm keccak --pool your-pool-here --wallet your-wallet-here --background --api-enable --api-port 17644

3. Отключить майнинг на GPU, использовать 7 потоков CPU с включенным расширенным журналом событий и сохранением его в файле  Logs\log.txt

SRBMiner-MULTI.exe --algorithm keccak --pool your-pool-here --wallet your-wallet-here --disable-gpu --cpu-threads 7 --log-file Logs\log.txt --extended-log

4. Complete example for mining on CPU and GPU only from the batch file (using 4 GPUs / and 7 CPU threads on the K12 algorithm)

SRBMiner-MULTI.exe --algorithm k12 --gpu-id 0,1,2,3 --gpu-intensity 26,25,26,26 --gpu-worksize 256,256,256,256 --gpu-threads 1,1,1,1 --cpu-threads 7 --pool your-pool-here --ВАШ_КОШЕЛЕК

5. Disable GPU mining, use 15 CPU threads with extended event logging enabled and saving it in the Logs\log.txt file, start Randomx mining from block height 1978433 and run the miner in the background.

SRBMiner-MULTI.exe --algorithm randomx --pool your-pool-here --wallet your-wallet-here --disable-gpu --cpu-threads 15 --log-file Logs\log.txt --extended-log --background --start-block-height 1978433
