-
As of 12/6/2017, Nicehash is closed down until further notice due to a hack involving 4800 missing Bitcoins. Please remove the "nicehash" parameter from the -poolname command (your chosen list of pools used) in the start.bat file and also remove the Nicehash-only parameters (algorithms) from the -algorithm command such as sianicehash, decrednicehash, pascal.
-
It is not recommended but to upgrade from a previous version of MultiPoolMiner, you may simply copy the 'Stats' folder.

Currently mining with upto 6 GPUs is fully supported. Where required advanced users can create additional or amend current miner files to support mining with more than 6 graphics cards.
====================================================================
-region [Europe/US/Asia] Choose your region or the region closest to you.
-poolname [miningpoolhub,miningpoolhubcoins,zpool,hashrefinery,nicehash]
The following pools are currently supported:
- MiningPoolHub https://miningpoolhub.com/
The 'miningpoolhub' parameter uses the 17xxx ports therefore allows the pool to decide on which coin is mined of a specific algorithm, while 'miningpoolhubcoins' allows for MultiPoolMiner to calculate and determine what is mined from all of the available coins (20xxx ports). Usage of the 'miningpoolhub' parameter is recommended as the pool have internal rules against switching before a block is found therefore prevents its users losing shares submitted due to early switching. A registered account is required when mining on MiningPoolHub (username must be provided using the -username command, see below).
- Zpool http://www.zpool.ca/ (Bitcoin address must be provided using the -address command, see below)
- Hash Refinery http://pool.hashrefinery.com (Bitcoin address must be provided using the -address command, see below)
- Nicehash https://www.nicehash.com/ (Bitcoin address must be provided using the -address command, see below)
IMPORTANT: The specified pool here will be used as default (preferred) but this does not rule out other pools to be included. Selecting multiple pools is allowed and will be used on a failover basis OR if first specified pool does not support that algorithm/coin. See the -algorithm command below for further details and example.
-username Your username you use to login to MiningPoolHub.
-workername To identify your mining rig.
-wallet Your Bitcoin payout address. Required when mining on Zpool, Hash Refinery and Nicehash.
-SSL Secure connection option.
-type [AMD,NVIDIA,CPU] Choose the relevant GPU(s) and/or CPU mining.
-algorithm
The following algorithms are currently supported:
Bitcore, Blakecoin, Blake2s, BlakeVanilla, C11, CryptoNight, Ethash, X11, Decred, Equihash, Groestl, HMQ1725, JHA, Keccak, Lbry, Lyra2RE2, Lyra2z, MyriadGroestl, NeoScrypt, Nist5, Pascal, Quark, Qubit, Scrypt, SHA256, Sia, Sib, Skunk, Skein, Timetravel, Tribus, BlakeVanilla, Veltor, X11, X11evo, X17, Yescrypt
- ethash2gb - can be profitable for older GPUs that have 2GB or less GDDR memory. It includes ethash coins that have a DAG file size of less than 2GB (and will be mined when most profitable). Ethereum and a few other coins have surpassed this size therefore cannot be mined with older cards.
- sianicehash and decrednicehash - if you want to include non-dual, non-Claymore Sia and Decred mining on Nicehash. NH created their own implementation of Sia and Decred mining protocol.
- siaclaymore - enable mining Sia as a secondary coin with Claymore Dual ethash miner on MiningPoolHub
Note that the pool selected also needs to support the required algorithm(s) or your specified pool (-poolname) will be ignored when mining certain algorithms. The -algorithm command is higher in execution hierarchy and can override pool selection. This feature comes handy when you mine on Zpool but also want to mine ethash coins (which is not supported by Zpool). WARNING! If you add all algorithms listed above, you may find your earnings spread across 3 different pools regardless what pool(s) you specified with the -poolname command.
-currency [BTC,USD,EUR,GBP,ETH ...] Choose the default currency or currencies your profit stats will be shown in.
-interval MultiPoolMiner's update interval in seconds. This is a universal timer for running the entire script (downloading/processing APIs, calculation etc). It also determines how long a benchmark is run for each miner file (miner/algorithm/coin). Default is 60.
-donate Donation of mining time in minutes per day to interbiznw. Default is 24. The downloaded miner software can have their own donation system built in. Check the readme file of the respective miner used for more details.
-watchdog Include this command to enable the watchdog feature which detects and handles miner and other related failures.

A1. The 'start.bat' file is an example that shows how to run the script without prompting for a username. Amend it with your username/address/workername and other relevant details such as region. Ensure it is run as Administrator to prevent errors.
Q2. A miner crashes my computer or does not work correctly. I want to exclude it from mining/benchmarking. What should I do?
A2. Simply locate the configuration file for that particular miner in the /Miners folder and delete the file or exclude that algorithm entirely (see FAQ#4 below). These have either .txt or .ps1 file extensions. Please note that some of the miners have multiple config files and/or can mine multiple coins/algorithms. (Planned enhancement for V3)
A3. You most likely have NVIDIA cards in your rig. Open the start.bat in a text editor and look for ‘-type amd,nvidia,cpu’ and change it to ‘-type nvidia,cpu’. This will disable the AMD exclusive miners and save you plenty of time when benchmarking. You can also exclude the cpu option if you don’t want to mine with your processor.
Q4. I only want to mine certain algorithms even if they are not the most profitable. I want to exclude algorithms. How do I do that?
A4. Open the start.bat in a text editor and look for ‘-algorithm cryptonight,ethash,equihash,groestl,lyra2z,neoscrypt,pascal,sia’. Delete the algorithms you don't want to mine. This can save you some time when benchmarking. For a full list of supported algorithms, check the Algorithms.txt. You can include any of these or even all of them if you please.
A5. It is showing you the stat for MultiPoolMiner vs the one miner. It means that the calculated earnings of MultiPoolMiner switching to different algorithms would be that much more profitable than if it had just mined that one particular algorithm the whole time. The number is still only an estimate of your earnings on the pool and may not directly reflect what you actually get paid. On MiningPoolHub and other multiple algorithm pools, coins have fluctuating values and MultiPoolMiner switches to the one that is the most profitable at that time. Because each pool has different delays in exchange and payout, the amount you actually earn my be very different. If there is a significant difference in percentage, you might want to reset the profitability stats by running the ResetProfit.bat file. Your actual (but still estimated) earning is shown in the second row.
A6. Simply run 'ResetBenchmark.bat' This deletes all files in the /Stats folder. This will force MultiPoolMiner to run the benchmarks again. If you only want to re-run a single benchmark for a coin or algorithm, locate the appropriate stat file for that particular coin or algorithm and delete it. Please note some of the miners can do multiple algorithms therefore have multiple stat files for the same miner and some of them create multiple stat files for the different configuration files they use.
A7. This is greatly dependant on the amount of selected algorithms and the number of device types chosen in the start.bat file. By default, each benchmark takes one minute. You can speed up benchmarking significantly by omitting unused device types. For example if you have a rig with AMD cards, you can tell MPM not to even launch the NVIDIA or CPU specific miner applications by removing these after the -type parameter in the start.bat file.
Q8. Is it possible to choose how many GPUs we want to allocate to mining or restrict mining on certain GPUs?
A8. This feature will possibly be implemented in the future (planned enhancement for MultiPoolMiner V3) but not yet supported by MultiPoolMiner.
A9. Excavator is developed by Nicehash and their EULA does not permit redistribution of their software which means you need to download Excavator yourself from https://github.com/nicehash/excavator/releases and place it in /Bin/Excavator/ (create the folder if does not exist). This is the permitted use of Excavator. Another solution is to delete the Excavator configuration file from the /Miners folder if you don't plan to use this miner.
A10. Simply run 'RemoveLogs.bat' This will delete all unnecessary and/or old log files that can indeed take up a lot of space of your storage device. It is perfectly safe to do so if space is required.
A11. This will reset your profit statistics and deletes all coin profibility data accumulated since MultiPoolMiner was first launched. This can be helpful when your predicted income stats (calculated average results) are broken which can happen when ie. an existing coin is added to a new exchange and the price falsely skyrockets due to low volume and liquidity. Bear in mind MultiPoolMiner becomes more accurate over time at calculating your profitability and running this scrypt will delete all that recorded data.
A12. Not all miners support multiple GPUs and this is a workaround to resolve this issue. MultiPoolMiner will try to open upto 6 instances of some of the miners to support systems with upto 6 GPUs or to overcome other problems found while testing. Doing so makes no difference in performance and donation amount to the miner sw developer (if applicable) will be the same percentage as if it was a single instance run for multiple GPUs ie. if one instance is run for five cards or five instances, one for each of the the five cards, that is still the same 1% donation NOT 5x1%.
Q13. MultiPoolMiner does not close miners properly (2 or more instances of the same miner accumulate over time)
A13. This is due to miner failure most likely caused by too much OVERCLOCKING. When miner fails it tries to recover which usually means restarting itself in the same window. This causes issues with the API connection to the miner and MultiPoolMiner thinks miner quit and launches another instance as a result. Due to default API port still being used by the first launched but failed miner, MPM can launch many instances of the same miner over time. This behaviour will be improved upon in the future but can only be completely solved by the user by lowering overclock to keep miners and the system stable.
Q14. Is it possible to change the payout currency from BTC to something else when mining on yiimp-based pools such as Zpool, Hash Refinery, etc?
A14. Yes, advanced users can edit the currency settings in each pool file by amending the password field (c=BTC), however, this is not recommended as your payout will become uncertain as all other payout currencies are internally exchanged therefore you may end up losing your earnings due to pool never having enough coins to pay you!
A15. Some cards may require special parameters to be used in order to make them (more) stable, such as setting intensity for specific miners/algos/GPUs. This can be done by heading to the /Miners folder and editing the relevant miner files. For example, for CcminerTpruvot.ps1 you can replace (mind the spaces!)
"x17" = "" # X17
"x17" = " -i 20" # X17
