September 9/17 VoskCoin Monthly Mining Update - I'm proud to announce that I have reached the 35k club. Welcome to gpu Mining MINING HASHRATES FOR AMD & NVIDIA GPU'S. ZCASH (ZEC) 120 WATTS: 1050/1870 +-270 SOL/S. Best GPUs for Cryptocurrency Mining (ZCash, Ether Mining) for 2018 By James on July 8, 2017. Overall, ZEC mining is a win for the green side.

Claymore's ZCash AMD GPU Miner. Latest version v6.0: • improved speed by about 20-25% (depends on card model). About 180H/s on stock 390. • '-i' parameter values are 0.4 now, default value is '-i 4'.

• fixed issue with mixed cards. LINKS: GOOGLE: MEGA: THERE IS ALSO RUSSIAN TRANSLATION OF THIS README: This version is for pools.

Catalyst (Crimson) 15.12 is required for best performance and compatibility. You can get very bad results for different drivers version, or miner can fail on startup. Set the following environment variables, especially if you have 2GB cards: GPU_FORCE_64BIT_PTR 0 GPU_MAX_HEAP_SIZE 100 GPU_USE_SYNC_OBJECTS 1 GPU_MAX_ALLOC_PERCENT 100 GPU_SINGLE_ALLOC_PERCENT 100 For multi-GPU systems, set Virtual Memory size in Windows at least 16 GB: 'Computer Properties / Advanced System Settings / Performance / Advanced / Virtual Memory'. This miner is free-to-use, however, current developer fee is 2.5%, every hour the miner mines for 90 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. This version is for recent AMD videocards only: 7xxx, 2xx, 3xx and 4xx, 2GB or more. There are builds for Windows x64 only. No 32-bit support. No NVidia support. COMMAND LINE OPTIONS: -zpool ZCash pool address.

Only Stratum protocol is supported. -zwal Your ZCash wallet address. Also worker name and other options if pool supports it. Pools that require 'Login.Worker' instead of wallet address are not supported directly currently, but you can use '-allpools 1' option to mine there. -zpsw Password for ZCash pool, use 'x' as password. -i mining intensity. Possible values: 0.4.

0 - lowest intensity and CPU usage, 4 - maximal intensity. You can also specify values for every card, for example '-i 4,2,4'. Default value is '4'. -allpools Specify '-allpools 1' if miner does not want to mine on specified pool (because it cannot mine devfee on that pool), but you agree to use some default pools for devfee mining. Note that if devfee mining pools will stop, entire mining will be stopped too. -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). Use '-di detect' value to detect correct GPU order for temperatures management (requires non-zero '-tt' option); note that it will not work properly if you do not want to assign all GPUs to miner. You can also turn on/off cards in runtime with '0'.' 9' keys and check current statistics with 's' key. -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'. -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. -nofee: set '1' to cancel my developer fee at all. In this mode some recent 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 2.5% 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 2.5% developer fee is too much for this miner and so on.

-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. Note: for Linux gpu-pro drivers, miner must have root access to manage fans, otherwise only monitoring will be available. -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. NOTE: Check 'KNOWN ISSUES' section. GPU indexes in temperature control sometimes don't match GPU indexes in mining!

-tstop set stop GPU temperature, miner will stop mining if GPU reaches specified temperature. For example, '-tstop 95' means 95C temperature. You can also specify values for every card, for example '-tstop 95,85,90'. This feature is disabled by default ('-tstop 0'). You also should specify non-zero value for '-tt' option to enable this option. NOTE: Check 'KNOWN ISSUES' section.

GPU indexes in temperature control sometimes don't match GPU indexes in mining! If it turned off wrong card, it will close miner in 30 seconds. You can also specify negative value to close miner immediately instead of stopping GPU, for example, '-tstop -95' will close miner as soon as any GPU reach 95C temperature. -fanmax set maximal fan speed, in percents, for example, '-fanmax 80' will set maximal fans speed to 80%.

You can also specify values for every card, for example '-fanmax 50,60,70'. Viacoin VIA Mining Startup. This option works only if miner manages cooling, i.e. When '-tt' option is used to specify target temperature. Decred DCR Solo Mining Calculator. Default value is '100'.

-fanmin set minimal fan speed, in percents, for example, '-fanmin 50' will set minimal fans speed to 50%. You can also specify values for every card, for example '-fanmin 50,60,70'. This option works only if miner manages cooling, i.e. When '-tt' option is used to specify target temperature.

Default value is '0'. -cclock set target GPU core clock speed, in MHz. If not specified or zero, miner will not change current clock speed. You can also specify values for every card, for example '-cclock 1000,1050,1100,0'. Unfortunately, AMD blocked underclocking for some reason, you can overclock only. -mclock set target GPU memory clock speed, in MHz. If not specified or zero, miner will not change current clock speed.

You can also specify values for every card, for example '-mclock 1200,1250,1200,0'. Unfortunately, AMD blocked underclocking for some reason, you can overclock only. -powlim set power limit, from -50 to 50. If not specified, miner will not change power limit. You can also specify values for every card, for example '-powlim 20,-20,0,10'.

-cvddc set target GPU core voltage, multiplied by 1000. For example, '-cvddc 1050' means 1.05V.

You can also specify values for every card, for example '-cvddc 900,950,1000,970'. Supports latest AMD 4xx cards only in Windows. -mvddc set target GPU memory voltage, multiplied by 1000.

For example, '-mvddc 1050' means 1.05V. You can also specify values for every card, for example '-mvddc 900,950,1000,970'. Supports latest AMD 4xx cards only in Windows. -mport remote monitoring/management port. Default port is 3333, specify '-mport 0' to disable remote monitoring/management feature.

Specify negative value to enable monitoring (get statistics) but disable management (restart, uploading files), for example, '-mport -3333' enables port 3333 for remote monitoring, but remote management will be blocked. You can also use your web browser to see current miner state, for example, type 'localhost:3333' in web browser. -colors enables or disables colored text in console. Default value is '1', use '-colors 0' to disable coloring. 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.
