XMRig Miner v6.16.2: Main features – Download and install – Settings

DOWNLOAD:

When we talk about Cryptonote (Cryptonight) for AMD GPUs, we prefer the SRBMiner miner due to the large number of supported options and features, however there is a good competitor called JCE miner Cryptonote CPU + GPU . JCE miner is a closed source software available as a binary for Windows only (for GPU) and with a 0.9% dev fee for GPUs (separate CPU miner has a higher fee, a version is available for this Linux). In terms of performance, the JCE miner is pretty much on par with the fastest alternatives like SRBminer , sometimes it can be a little faster, sometimes a little slower, depending on the algorithm and settings. For example, our latest experience shows slightly better performance for TUBE mining using JCE compared to SRB 1.7.5 on an RX 580. The JCE miner does support a lot of Cryptonothe (Cryptonight) variants, so you can use it for pretty much all the popular variants . There is support for both SSL and NiceHash extraction functionality.

Quick setup of a batch file

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

1. SRBMiner-MULTI.exe - command to launch the SRBMiner application
2. —algorithm randomx — specify the algorithm for mining
3. —pool xmr-eu1.nanopool.org — specify the pool address
4. 14444 — specify the pool port
5. —wallet 44tLjmXrQNrWJ5NBsEj2R77ZBEgDa3fEe9GLpSf2FRmhexPvfYDUAB7EXX1Hdb3aMQ9FLqdJ56yaAhiXoRsceGJCRS3Jxkn.5d3c802ee0f8e12e4eb9792722b7816a42178aa 29ef7477c138ddb940c55648d indicate coin purse + after the dot. The wallet can be obtained either from , or you can install a Monero cold wallet.
6. —gpu-target-temperature 70 — the program will strive to maintain this temperature
7. —gpu-off-temperature 83 — the miner will turn off when this temperature is reached and turn on when it drops
8. —send-stales — send outdated shares to the pool (some pools partially pay for them or award bonuses).
9. —enable-restart-on-rejected — automatically restart the miner if there are too many rejected shares

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

After launching the program, we will see the following window:

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.

Bottom line

We can recommend this program to all miners, regardless of experience in cryptocurrency mining. Nanominer delivers good performance, and thanks to constant updates, the hashrate is getting larger and stability is improving. Through the application, you can adjust the core and memory frequency of video cards from both manufacturers, which further increases your income.

At the same time, a beginner will not have to deal with an abundance of settings, since everything can be used immediately after downloading nanominer. The developer's commission is competitive, which is also good news for 2022 miners. A good program with decent functionality, which we recommend for use.

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:

1. user-defined algorithm in the pools configuration file (pools.txt)
2. 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:
This is where 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}]}

Driver requirements

In order to work with NVIDIA nanominer GPUs, you need Nvidia driver 410.48 and later on Linux or 411.31 and later on Windows. The nanominer cuda11 version requires Nvidia driver 455.23 and later on Linux or 456.38 and later on Windows. Nvidia 30xx series GPUs will only work with the cuda11 version of the miner.

Nanominer is a software product developed by nanopool to create cryptocurrency units based on the following algorithms:

nanominer also supports Zilliqa mining in current configurations (see example configurations):

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

Speed

It's hard to compare GPU Miners. There are a lot of external parameters: the card itself, its memory, the biosmod, the drivers, the overclocking, the Power Limit…

However, according to the first feedbacks, here's the status on CN-v7:

• JCE is faster than any other miner on small RX cards (RX550 and RX560). They are my favorite cards, and the ones I use on most of my rigs.
• JCE is always faster than the Wolf0-based miners (Stak, Xmrig, Gateless...). This is not fair since I can read their code and they cannot read mine, but it's a proof JCE is not a copy-paste of their code.
• JCE is surprisingly fast on Vega, reaching 2050+ on Vega 64 on CN-v7.
• JCE is close to SRB and Claymore otherwise, sometimes slightly above, sometimes slightly below.
• I got mixed results on HD7800. I measured higher hashrate than other miners on my rig, but got opposite comments from some users. To be tested.
• JCE is bad on small 1G cards compared to the legendary Claymore 9.7, but this miner is no longer supported.

On CN-v8:

• Still always better than the open-source miners (Stak, Xmrig, Gateless...).
• Claymore is just no longer compatible.
• JCE is the best on older cards like HD6000 and HD7000 and R7/R9 series
• RX560 cards reach 500+, 850+ on R9 290/X, RX570/580 cards reach 1000+
• 420+ on HD7850 2G
• 480+ on HD7950 3G

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
