Claymore's NeoScrypt AMD GPU Miner.
=========================

Latest version is v1.2:

- improved stratum routines to support more pools.
- added RX550 card support.


WARNING: NeoScrypt algorithm is VERY HOT, make sure you have powerful PSU and good GPU cooling, use "-powlim 50" option to get full hashrate.

MEGA v1.2: https://mega.nz/#F!FWQxmAwY!DCAmI1NwbFB1eFGuMbOmVw


v1.1:

- fixed issue with rejected shares.
- reduced CPU usage for systems with a lot of GPUs.


This is POOL version. Use any recent drivers. Miner requires up to 1.1GB of GPU memory.
For multi-GPU systems, set Virtual Memory size in Windows at least 16 GB (better more):
"Computer Properties / Advanced System Settings / Performance / Advanced / Virtual Memory".

This miner is free-to-use, however, current developer fee is 2%, every hour the miner mines for 72 seconds for developer.
If you don't agree with the dev fee - don't use this miner, or use "-nofee" option.
Attempts to cheat and remove dev fee will cause a bit slower mining speed (same as "-nofee 1") though miner will show same hashrate.
Miner cannot just stop if cheat is detected because creators of cheats would know that the cheat does not work and they would find new tricks. If miner does not show any errors or slowdowns, they are happy.

This miner is heavily optimized and therefore supports only most popular AMD GPU chips: Pitcairn, Tahiti, Hawaii, Tonga, Fiji, Ellesmere, Baffin, Vega.

Only Windows x64 is supported currently. No Linux support. No 32-bit support. No NVidia support.



COMMAND LINE OPTIONS:

-pool NeoScrypt pool address. Only Stratum protocol is supported.

-wal Your wallet address. Also worker name and other options if pool supports it.

-psw Password for NeoScrypt pool, use "x" as password, and/or any other options if pool supports them.

-a algorithm mode for Ellesmere cards (RX470/RX480/RX570/RX580 cards), for other cards always "-a 1" is used. You can specify "-a 1" (default) or "-a 2" and find the best hashrate for your card.
You can also set this option for every card individually, for example "-a 1,2,1".

-di GPU indexes, default is all available GPUs. For example, if you have four GPUs "-di 02" will enable only first and third GPUs (#0 and #2).
You can also turn on/off cards in runtime with "0"..."9" keys and check current statistics with "s" key.
For systems with more than 10 GPUs: use letters to specify indexes more than 9, for example, "a" means index 10, "b" means index 11, etc; also "a", "b", and "c" keys allow you to turn on/off GPU #10, #11 and #12 in runtime.

-ftime failover main pool switch time, in minutes, see "Failover" section below. Default value is 30 minutes, set zero if there is no main pool.

-wd watchdog option. Default value is "-wd 1", it enables watchdog, miner will be closed (or restarted, see "-r" option) if any thread is not responding for 1 minute or OpenCL call failed.
Specify "-wd 0" to disable watchdog.

-r Restart miner mode. "-r 0" (default) - restart miner if something wrong with GPU. "-r -1" - disable automatic restarting. -r >20 - restart miner if something
wrong with GPU or by timer. For example, "-r 60" - restart miner every hour or when some GPU failed.
"-r 1" closes miner and execute "reboot.bat" file ("reboot.bash" or "reboot.sh" for Linux version) in the miner directory (if exists) if some GPU failed.
So you can create "reboot.bat" file and perform some actions, for example, reboot system if you put this line there: "shutdown /r /t 5 /f".

-minspeed minimal speed, in KH/s. If miner cannot reach this speed for 5 minutes for any reason, miner will be restarted (or "reboot.bat" will be executed if "-r 1" is set). Default value is 0 (feature disabled).
You can also specify negative values if you don't want to restart miner due to pool connection issues; for example, "-minspeed -3000" will restart miner only if it cannot reach 3Mh/s at good pool connection.

-retrydelay delay, in seconds, between connection attempts. Default values is "20". Specify "-retrydelay -1" if you don't need reconnection, in this mode miner will exit if connection is lost.

-dbg debug log and messages. "-dbg 0" - (default) create log file but don't show debug messages.
"-dbg 1" - create log file and show debug messages. "-dbg -1" - no log file and no debug messages.

-logfile debug log file name. After restart, miner will append new log data to the same file. If you want to clear old log data, file name must contain "noappend" string.
If missed, default file name will be used.

-logsmaxsize maximal size of debug log files, in MB. At every start the miner checks all files in its folder, selects all files that contain "_log.txt" string and removes oldest files if summary files size is larger than specified value.
Specify "-logsmaxsize 0" to cancel old logs removal. Default value is 1000 (i.e. about 1GB of log files are allowed).

-nofee set "1" to cancel my developer fee at all. In this mode some optimizations are disabled so mining speed will be slower by about 5%.
By enabling this mode, I will lose 100% of my earnings, you will lose only 3% of your earnings.
So you have a choice: "fastest miner" or "completely free miner but a bit slower".
If you want both "fastest" and "completely free" you should find some other miner that meets your requirements, just don't use this miner instead of claiming that I need
to cancel/reduce developer fee, saying that 2% developer fee is too much for this miner and so on.

-benchmark benchmark mode, specify "-benchmark 1" to see hashrate for your hardware.

-li low intensity mode. Reduces mining intensity, useful if your cards are overheated. Note that mining speed is reduced too.
More value means less heat and mining speed, for example, "-li 10" is less heat and mining speed than "-li 1". You can also specify values for every card, for example "-li 3,10,50".
Default value is "0" - no low intensity mode.

-tt set target GPU temperature. For example, "-tt 80" means 80C temperature. You can also specify values for every card, for example "-tt 70,80,75".
You can also set static fan speed if you specify negative values, for example "-tt -50" sets 50% fan speed. Specify zero to disable control and hide GPU statistics.
"-tt 1" (default) does not manage fans but shows GPU temperature and fan status every 30 seconds. Specify values 2..5 if it is too often.

-ttli reduce entire mining intensity (for all coins) automatically if GPU temperature is above specified value. For example, "-ttli 80" reduces mining intensity if GPU temperature is above 80C.
You can see if intensity was reduced in detailed statistics ("s" key).
You can also specify values for every card, for example "-ttli 80,85,80". You also should specify non-zero value for "-tt" option to enable this option.
It is a good idea to set "-ttli" value higher than "-tt" value by 3-5C.


CONFIGURATION FILE

You can use "config.txt" file instead of specifying options in command line.
If there are not any command line options, miner will check "config.txt" file for options.
If there is only one option in the command line, it must be configuration file name.
If there are two or more options in the command line, miner will take all options from the command line, not from configuration file.
Place one option per line, if first character of a line is ";" or "#", this line will be ignored.
You can also use environment variables in "pools.txt" and "config.txt" files. For example, define "WORKER" environment variable and use it as "%WORKER%" in config.txt or in pools.txt.



SAMPLE USAGE

miningpoolhub:

NeoScryptMiner.exe -pool hub.miningpoolhub.com:20510 -wal Redhex.sample -psw x

nicehash:

NeoScryptMiner.exe -pool stratum+tcp://neoscrypt.eu.nicehash.com:3341 -wal YourBtcWalletAddress -psw x


FAILOVER

Use "pools.txt" file to specify additional pools. This file has text format, one pool per line. Every pool has 3 connection attempts.
Miner disconnects automatically if pool does not send new jobs for a long time or if pool rejects too many shares.
If the first character of a line is ";" or "#", this line will be ignored.
Do not change spacing, spaces between parameters and values are required for parsing.
If you need to specify "," character in parameter value, use two commas - ,, will be treated as one comma.
You can reload "pools.txt" file in runtime by pressing "r" key.
Pool specified in the command line is "main" pool, miner will try to return to it every 30 minutes if it has to use some different pool from the list.
If no pool was specified in the command line then first pool in the failover pools list is main pool.
You can change 30 minutes time period to some different value with "-ftime" option, or use "-ftime 0" to disable switching to main pool.
You can also use environment variables in "pools.txt" and "config.txt" files. For example, define "WORKER" environment variable and use it as "%WORKER%" in config.txt or in pools.txt.
You can also select current pool in runtime by pressing "e" key.


KNOWN ISSUES

- Windows 10 Defender recognizes miner as a virus, some antiviruses do the same. Miner is not a virus, add it to Defender exceptions.
I write miners since 2014. Most of them are recognized as viruses by some paranoid antiviruses, perhaps because I pack my miners to protect them from disassembling, perhaps because some people include them into their botnets, or perhaps these antiviruses are not good, I don't know. For these years, a lot of people used my miners and nobody confirmed that my miner stole anything or did something bad.
Note that I can guarantee clean binaries only for official links in my posts on this forum. If you downloaded miner from some other link - it really can be a virus.
However, my miners are closed-source so I cannot prove that they are not viruses. If you think that I write viruses instead of good miners - do not use this miner, or at least use it on systems without any valuable data.



TROUBLESHOOTING

1. Install latest drivers.
2. Disable overclocking.
3. Set environment variables as described above.
4. Set Virtual Memory 16 GB.
5. Reboot computer.
6. Check hardware, risers.
