  Requirements:
  1. A x86_64 architecture CPU with a minimum of SSE2 support. This includes Intel Core2 and newer and AMD equivalents. AES optimizations require a CPU with AES_NI including Intel Westmere and newer and AMD equivalents. Further optimizations are available on some algos for CPUs with AVX (Sandybridge), AVX2 (Haswell, Ryzen), AVX512 (Skylake-X), SHA (Ryzen, Icelake), and VAES (Icelake).
  
  32 bit CPUs, ARM CPUs, Intel Atom, Raspberry PI, etc, are not supported.
  Mobile devices are not recommended because they aren't designed for continuous full load.
  
  2.  64 bit Windows OS is supported using the pre-compiled binaries package or may be cross-compiled using a Linux sysytem with mingw.
   FreeBSD is not actively tested but should work, YMMV.
  Apple and Android operating systems are not supported.
  Older CPUs, other architectures and operating systems may be supported by TPruvot's cpuminer-multi.
  
  
  Security warning:
  Miner programs are often flagged as malware by antivirus programs. This is usually a false positive, they are flagged simply because they are cryptocurrency miners. However, some malware has been spread using the cover that miners are known to be subject to false positives. Always be on alert. The source code of cpuminer-opt is open for anyone to inspect. If you don't trust the software don't download it.
   Some cryptographic code has been taken from trusted sources but has been modified for speed at the expense of accepted security practices. This code should not be imported into applications where secure cryptography is required.
  
  
  Errata:
  
• Old algorithms that are rarely used anymore will not get the latest optimizations.
• Cryptonight and variants are no longer supported.
• Neoscrypt crashes on Windows, use legacy version.
• Hodl requires a CPU with AES, use legacy version if without.
• Benchmark testing does not work on several algos.

Usage

Configurations
Before you started the miner the first time there are no config files available. Config files will be created at the first start. The number of files depends on the available backends. config.txt contains the common miner settings. pools.txt contains the selected mining pools and currency to mine. amd.txt, cpu.txt and nvidia.txt contains miner backend specific settings and can be used for further tuning.
Note: If the pool is ignoring the option rig_id in pools.txt to name your worker please check the pool documentation how a worker name can be set.

Usage on Windows
1. Double click the bittube-miner.exe file
2. Fill in the pool url settings, currency, username and password

disable the dialog
set XMRSTAK_NOWAIT=1
for non UAC execution.
Press any key to exit
CPU Only:
bittube-miner --noAMD --noNVIDIA
NVIDIA/AMD Only:
The miner will automatically detect if CUDA (for NVIDIA GPUs) or OpenCL (for AMD GPUs) is available.
bittube-miner --noCPU
NVIDIA via OpenCL
It is possible to use the OpenCl backend which is originally created for AMD GPUs with NVIDIA GPus. Some NVIDIA GPUs can reach better performance with this backend.
bittube-miner --openCLVendor NVIDIA --noNVIDIA
Docker image usage
You can run the Docker image the following way:
docker run --rm -it -u $(id -u):$(id -g) --name fireice-uk/bittube-miner -v "$PWD":/mnt bittube-miner
docker stop bittube-miner
docker run --rm -it -u $(id -u):$(id -g) --name fireice-uk/bittube-miner -v "$PWD":/mnt bittube-miner --config config.txt
Debug the docker image by getting inside:
docker run --entrypoint=/bin/bash --rm -it -u $(id -u):$(id -g) --name fireice-uk/bittube-miner -v "$PWD":/mnt bittube-miner
FAQ

Virus Protection Alert
Some virus protection software flags the miner binary as malware. This is a false positive — the software does not contain any malware (and since it is open source, you can verify that yourself!) If your antivirus software flags bittube-miner, it will likely move it to its quarantine area. You may have to whitelist bittube-miner in your antivirus.

Change Currency to Mine

If the miner is compiled for Monero and Aeon than you can change

the value currency in the config or
start the miner with the command line option --currency monero or --currency aeon7
run bittube-miner --help to see all supported currencies and algorithms

How can I mine Monero
Set the value currency in pools.txt to monero.

Which currency must be chosen if my fork coin is not listed
If your coin you want to mine is not listed please check the documentation of the coin and try to find out if cryptonight or cryptonight-lite is the used algorithm. Select one of these generic coin algorithms.

Important guidelines for using NHM:

NiceHash Miner is usually flagged by AV (anti-virus) software. This is normal, as almost every mining software on the market is blacklisted by AV. Just make an exception in your AV software to enable the proper operation of NHML.

You may have to add an exception in your browser to enable NHM download. Learn how.

We cannot guarantee for every 3rd party miner code thus you agree to use it at your own risk.

We suggest you don’t use cryptocurrency wallets or have any access to any cryptocurrency, sensitive or important data on the same computer where you use NHM. NiceHash will never ask or use your private keys, but we cannot guarantee the same for the 3rd party miners included in NHM now or any time in the future.

Add an exception to Windows Defender for the NiceHash Miner folder (after you unzip the package).

Check out the Wiki for instructions on getting started, upgrading, troubleshooting, and more.

If benchmarking fails, try running in "Precise" or manually benchmarking

If autodownload fails, download the miner bins manually and unzip them to the miner plugin bins path.

Miner binary package sources are in:
nhm\miner_plugins\XPlugin\internals\MinersBinsUrlsSettings.json for XPlugin.

3. Disable GPU mining, use 7 CPU threads with extended logging enabled and saved to Logs\log.txt file

Code:
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. Full example for CPU & GPU mining set only from cmd (4 GPU/s used and 7 CPU threads on K12 algorithm)

Code:
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 --wallet your-wallet-here

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

Code:
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


CPU MINING SETUP:

If you don't set the --cpu-threads or --cpu-affinity parameters, miner will try to automatically find the best setup for you system.
Sometimes the auto setup won't find the optimal settings so you should find it by experimenting.
You need to set the number of worker threads (--cpu-threads) and bind them to the appropriate PU (processing unit) with --cpu-affinity.


Examples to get you started:

4 CORE / 8 THREADS CPU :

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

6 CORE / 12 THREADS CPU :

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


RANDOMX EXTRA TWEAKS:

To enjoy the benefits of the increased hashrate:

1. Miner must run with administrator privileges [right click on SRBMiner-MULTI.exe->properties->compatibility-> check 'Run this program as an administrator' option-> click OK button
2. Make sure WinRing0x64.sys is in the same folder as SRBMiner-MULTI.exe
Enabling the extra tweaks, some register values are changed which will revert back to the original value after a computer restart.
If miner starts crashing, or creates bad results after enabling the extra tweaks, you can try the '--randomx-use-tweaks' parameter, where you can define which tweak/s you want to enable.
Without this option miner enables all available tweaks (same as --randomx-use-tweaks 0123 for AMD, --randomx-use-tweaks 0 for Intel) , but with '--randomx-use-tweaks' you can define which ones you want to use.

There are at the moment :
Intel - 1 tweak
Amd - 5 tweaks

Index starts from 0, so you have 0 1 2 3 4 for options on AMD.

Here's an example :

+ Use tweaks number 0 and 3 (dont use 1 and 2)

Code:
SRBMiner-MULTI.exe --algorithm randomx --pool your-pool-here --wallet your-wallet-here --password your-password-here --randomx-use-tweaks 03
The order of tweaks doesn't matter, so writing 03 is same as 30.
What you should do is to find which tweak, or combination of tweaks, makes the problems.
You should try enabling tweaks one by one, and test to see if miner runs stable with one tweak, and if it does, test the next one etc.
Luckily there are not so many combinations for you try (because 0123 is for example same as 3021 or 1302.. )

So start with :
Code:
SRBMiner-MULTI.exe --algorithm randomx --pool your-pool-here --wallet your-wallet-here --password your-password-here --randomx-use-tweaks 0

If it runs without crashing for some time, try the next one :

Code:
SRBMiner-MULTI.exe --algorithm randomx --pool your-pool-here --wallet your-wallet-here --password your-password-here --randomx-use-tweaks 1 and so on, until you find the one that makes the trouble.
Then try combining tweaks to find a combination that works for you.

If you have older gen. Ryzens, try this combination of tweaks :
Code:
--randomx-use-tweaks 0134


INFORMATIONS:

SRBMiner-Multi is supported by Awesome Miner
If you get "Insufficient system resources available to allocate X kB in large-page memory" message, that means you dont have enough FREE memory left, a computer restart should solve this.
Large-page memory regions may be difficult to obtain after the system has been running for a long time because the physical space for each large page must be contiguous, but the memory may have become fragmented.
If you still get this message even after restarting, try increasing virtual memory.
You can find all the parameters and everything you need to get going in the readme.txt file.
This thread is self moderated, because in the previous SRBMiner thread there was too much spam and garbage, which wasn't removed by the forum moderators.
