SRBMiner-MULTI CPU and AMD GPU Miner 0.8.8: Download and configure for RandomX

Fast start

To start as quickly as possible it will be enough:

Download the archive with the program.
Unpack to any convenient place.
Change the wallet to yours in a file with a .bat extension.

The archive with the program contains 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. Just create/edit a ready-made .bat file (Windows) or open a terminal (Linux).

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 9gj5rYtg1sGwdvoXGJswrSfPBXiXJgmyjZVE Q9p5fvZrCAfu6zT --gpu-boost 3 pause

How to configure .bat file

In order to start mining we need to create or edit a file with a .bat extension. Specify the following commands in it:

SRBMiner-MULTI.exe - command to launch the SRBMiner application.
--disable-cpu — disable mining on the processor.
—algorithm autolykos2 — specify the algorithm for mining.
—pool ergo.herominers.com:10250 — specify the pool address and port.
—wallet 9gj5rYtg1sGwdvoXGJswrSfPBXiXJgmyjZVEQ9p5fvZrCAfu6zT indicate the wallet of the coin. You can get a wallet either on an exchange or install a cold wallet.
--gpu-boost 3 - Used to increase the hashrate of your GPU. The parameter is activated only if the miner is launched with administrator rights.

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

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

Having launched the program, we will see the following console window:

Sample batch file for RandomX

SRBMiner-MULTI.exe - command to launch the SRBMiner application
—algorithm randomx — specify the algorithm for mining
—pool xmr-eu1.nanopool.org — specify the pool address
14444 — specify the pool port
—wallet 44tLjmXrQNrWJ5NBsEj2R77ZBEgDa3fEe9GLpSf2FRmhexPvfYDUAB7EXX1Hdb3aMQ9FLqdJ56yaAhiXoRsceGJCRS3Jxkn.5d3c802ee0f8e12e4eb9792722b7816a42178aa 29ef7477c138ddb940c55648d indicate coin purse. The wallet can be obtained either from the exchange or by installing a Monero cold wallet.
—gpu-target-temperature 70 — the program will strive to maintain this temperature
—gpu-off-temperature 83 — the miner will turn off when this temperature is reached and turn on when it drops
—send-stales — send outdated shares to the pool (some pools partially pay for them or award bonuses).
—enable-restart-on-rejected — automatically restart the miner if there are too many rejected shares

Sample batch file:

setx GPU_MAX_HEAP_SIZE 100 setx GPU_MAX_USE_SYNC_OBJECTS 1 setx GPU_MAX_ALLOC_PERCENT 100 setx GPU_MAX_SINGLE_ALLOC_PERCENT 100 @echo off cd %~dp0 cls set LOGTIME=%date:~10.4%_%date:~4.2%_%date:~7.2%_ %time:~0.2%_%time:~3.2% set LOGTIME=%LOGTIME: =% set LOGTIME=%LOGTIME:,=.%.txt SRBMiner-MULTI.exe --algorithm randomx --pool xmr-eu1 .nanopool.org:14444 —wallet 44tLjmXrQNrWJ5NBsEj2R77ZBEgDa3fEe9GLpSf2FRmhexPvfYDUAB7EXX1Hdb3aMQ9FLqdJ56yaAhiXoRsceGJCRS3Jxkn.rig1 pause

We wrote in the batch file only those commands that will help you connect to the pool and start the process of mining cryptocurrency. However, to improve performance, you may need to configure some other command line arguments, depending on your hardware type.

Fixed bug with wrong version of verushash algorithm solution

v0.8.4

Increased performance on the Heavyhash algorithm for GPUs
Fixed display of hash rate during GPU auto-tuning.

v0.8.3

Increased performance on the Heavyhash algorithm for GPUs ( up to ~ 20% on some maps)
Fixed problem with recognition of some GPUs in newer drivers (does not work since version 0.8.1)
Redesigned hashrate report / statistics - now the average value for 1 min / 1 hour / 6 hours / 12 hours is displayed (also in the API).

v0.8.2

Added the ability to preload datasets using the autolykos2 algorithm with the --gpu-autolykos2-preload parameter (even on 4 GB cards!)
Slightly faster dataset creation on some GPUs
Job notifications are now displayed less frequently in the console unless extended logging is enabled.
Autolykos2 kernels for Hawaii, Tonga and Fiji have been replaced with kernels from ver. 0.7.3
Fixed bugs in algorithm switching mode ('- multi-algorithm-job-mode 3')

Dataset preloading can increase the hashrate on the pool side! (this means more profit)

Works even on GPUs with 4Gb!

For example, if you are configured to preload 1 dataset, that means it will create a dataset for the current and next block. When the next block arrives, the dataset will be loaded, which means the GPU can resume immediately (without creating the dataset). Additional GPU memory required.

There are 2 types of preload:

If you set the preload value to 1, it will constantly load the next block (preferably for 4-8GB GPUs).
If you set the preload value> 1, it will preload X datasets, and when a block arrives that hasn't been loaded yet, it will be generated so the miner can start working with it, and then X datasets will be preloaded again. ...

Setting up configuration files

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

Program files

Configuration options in the config.txt file

"algorithm" specify the algorithm specify the intensity (1-31), if set to 0, the miner will try to find the best settings (intensity, worksize, threads)

"raw_intensity" specify the number of global threads, use if you want to fine-tune the intensity

"worksize" specify the size of the local workgroup

"threads" specify the number of video card threads to use

“giveup_limit” specify the number of times to try to connect to the pool before switching to the next pool from the pool.txt file. If set to 0, the miner will exit and will not retry the connection.

"timeout" specify the time when the connection to the pool is considered expired

"retry_time" specify the time how long to wait before trying to reconnect to the pool

"reboot_script_gpu_watchdog" specify a file name for the script in the miner directory, if set, disables the built-in procedure for restarting the miner when the video card fails and instead runs the script you specify

"main_pool_reconnect" specify the time (minimum 3 minutes or 180 seconds) how often to try to reconnect to the main pool. Default is 10 minutes.

"wallet" your wallet

"password" your password

"nicehash" true or false, set to true if you are using Nicehash

“job_timeout” specify the number in seconds, if during this period no jobs were received from the pool, then the miner will reconnect to the pool (disabled by default)

"max_difficulty" specify a decimal number, if the difficulty of the pool is higher than this value, the miner will reconnect to the pool

"pool_use_tls" true or false, if true, then the miner will use the SSL/TLS protocol to connect to the pool

"algorithm" specify an algorithm to inform the miner what algorithm the pool is using (--list-algorithms)

"start_block_height" specify a number to start mining when a certain block height is reached. The pool should send this information

“algo_min_time” indicate the time used with the ability to switch algorithms (the minimum time for mining the same algorithm). Default 10 min.

"keepalive" true or false, not every pool supports this

Video card configuration in the config.txt file

“id” indicate the identifier of the video card, it can be found with the --list-devices parameter

"intensity" indicate the intensity (1-31), if set to 0, the miner will try to find the best settings (intensity, worksize, threads)

"raw_intensity" specify the number of global threads, use if you want to fine-tune the intensity

"worksize" specify the size of the local workgroup

"threads" specify the number of GPU threads to use

"tweak_profile" specify a profile (0-10) that applies settings to video cards that can increase hashrate. 0 - no tweaks, 10 - max. If you add L after the number, it will use low settings (eg "4L")

“target_fan_speed” specify the fan speed value (0-6000), the miner will try to set the fan speed on video cards to this value. Value in RPM (number of rounds per minute) (ADL must be enabled)

“off_temperature” specify the temperature in degrees C when to turn off the video card if it reaches this value. The card will be turned on again when the temperature drops

"adl_type" specify the ADL type (1-3), 1 - USE FOR OVERDRIVEN, 2 - USE FOR OVERDRIVE5, 3 - USE FOR OVERDRIVE8. Defaults to 1 if not set. Option 2 (Overdrive5) is suitable for older cards, 3 for Radeon VII and newer

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 set the --cpu-threads or --cpu-affinity options, the miner will automatically try to find the optimal settings for your system.

Sometimes automatic tuning doesn't find the optimal settings, so you have to experiment to find it.

You need to set the number of threads (--cpu-threads) and bind them to the appropriate processor using the --cpu-affinity command.

Mask calculator here: https://bitsum.com/tools/cpu-affinity-calculator/

Examples

4 CORE/8 THREADS PROCESSOR:

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

6 CORE/12 THREADS PROCESSOR:

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 ability to switch algorithms, rename the file 'algorithms_example.txt' to 'algorithms.txt'.

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

Pools for multiple coins/algorithms can be defined in the same config file, and when a manual switchover/automatic switchover occurs when a pool fails, the miner will restart with the 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 using the randomxl algorithm. If the user changes the pool manually or there is a failover to the next pool, SRBMiner-MULTI will connect to the next pool (in this example nanopool) using

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. You can read how it works on their page (https://moneroocean.stream/#/help/faq)

Example:

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

If the algorithm is supported in SRBMiner-MULTI and also in MoneroOcean (you can see what algorithms they support here: https://moneroocean.stream/#/coins), it can be used to switch algorithms.

You can find the file 'start-mining-monero-ocean.bat' which uses the Pools\pools-monero-ocean.txt configuration file where you previously changed the wallet address.

If you do not want to include every algorithm supported by the miner in the algorithm switching process, you will need to edit the algorithms.txt file to suit your needs.

algorithms.txt file:

Here you define individual settings for each algorithm.

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

Teams:

“algorithm” name of the algorithm [run the miner with the --list-algorithms command to see the available ones]

config" path to the configuration file to use in this algorithm path to the startup script you want to run when you start the miner

“hashrate” is the hashrate of your system using this algorithm. Only used with pool side algorithm switch

Example:

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

Web statistics with GUI

You must first enable the API using the --api-enable command in the start.bat file

web statistics

Set the name of your rig (computer) using --api-rig-name rig_name is also set in start.bat

Once you have launched the miner, you can access the statistics page in your browser:

https://127.0.0.1:21550/stats

There are also three other options that can help you reboot the miner, shutdown or reboot your rig remotely:

--api-rig-restart-url

This must be a unique string that, when accessed in a browser, causes the computer to restart. The miner must have administrator rights.

--api-rig-shutdown-url

This must be a unique string that, when accessed in the browser, causes the computer to shut down. The miner must have administrator rights.

--api-miner-restart-url

This should be a unique string that is accessed in the browser when SRBMiner-MULTI is restarted

Example:

SRBMiner-MULTI.exe --config-file Config\config-randomxl.txt --pools-file Pools\pools.txt --api-enable --api-rig-restart-url 12345fff --api-rig-shutdown-url 54321fff --api- miner-restart-url restart_my_srb

Visiting this URL restarts your farm:

https://127.0.0.1:21550/12345fff

Visiting this URL shuts down your farm:

https://127.0.0.1:21550/54321fff

Visiting this URL restarts SRBMiner-MULTI:

https://127.0.0.1:21550/restart_my_srb

Setting the background mode

Background mode means that the miner will work without a console window. Both CPU and GPU miners can run in the background.

The SRBMiner-MULTI process can be found in the task manager if you want to stop/disable a process running in the background.

Example:

Run CPU mining in the background (no console window) using 3 CPU threads

SRBMiner-MULTI.exe --algorithm k12 --pool your-pool-here --wallet YOUR_WALLET --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 (https://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. Disable GPU mining, use 7 CPU threads with extended event logging enabled and saving it in the Logs\log.txt file

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 —YOUR_WALLET

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
