Python script to automatically find optimized and stable GPU overclock settings to mine Ethereum

CryptoTune

Python script to automatically find optimized and stable GPU overclock settings to mine Ethereum and other CryptoCoins.

Warning

As this software needs to be run as admin, do not use it if you are not sure what you are doing! The software will not try to steal your data in any way, but i'm only some dude from the internet so please do not trust me on that :)

What it does

This software does exactly what you would do manually to reach peak speeds/efficiency on your GPUs - but in parallel and without the effort.

Features for automated GPU Overclocking & Power Limiting

• Thermal Throttling detection
• Automatic down-clocking on mining software crash or invalid shares
• Three Optimization Modes:
  • Efficiency: get the best Hash/Watt ratio
  • Speed: achieve the highest sense-making speed
  • Profitability: get the best profitability with your power costs
• Parallel Optimization of all GPUs at the same time

Thermal Throttling Detection

If your GPUs are reducing their Hashrate due to high temps or too high overclocks, the tool will inform you and reduce the clocks accordingly.

Finding maximum Memory OC

The software will start overclocking your memory until either the mining software crashes or your GPU created invalid shares. This will help in reaching the maximum possible speed.

Finding minimum Core Clock

After finding the maximum possible memory clock, the software will start reducing the core clock until a significant decrease in speed is detected. This will help decreasing the power consumption and temperatures of your GPUs.

Finding minimum Power Limits

After clocks are fine tuned, each GPUs power limit will be reduced to lower temperatures and increase efficiency (lower power costs). There are three modes to choose from:

• Mode 0: Maximum Efficiency (default): your GPU will probably not reach it's top hash rate, but it will be the most efficient (power/hash) you can achieve
• Mode 1: Maximum Speed (hybrid): Your GPU will run some kHashes below it's maximum speed but can achieve this with a lot less power than default (see "margin"-parameter)
• Mode 2: Maximum Profitability: Enter your powerCost and "daily dollars per MHash" and get the best settings for achieving the highest profitability

Tuning all GPUs in parallel

This software tracks your GPUs state every second, creates statistics from that and automatically sets your GPUs to your preferred model. All GPUs are tuned at the same time, therefore it is fast and accurate in it's decision making without writing down hundreds of values, speeds and efficiencies manually.

Mining Software

There are two miners (GMiner 2.50 & T-Rex Miner 0.20) included, but as code cannot be easily checked i strongly recommend you download and add your own mining binaries and rename (if needed) to "miner.exe".

Limitations

• Windows 10 only
• GMiner & T-Rex Miner only (NBMiner and others planned)

Requirements

Following requirements need to be met in order for the tool to work properly

• NVIDIA Driver installed (especially nvidia-smi)
• Up-to-date Windows 10
• Python 3.6 or higher installed
• executing script with Administrative Access (open CMD with admin privileges or right-click "start.bat" -> run as admin)
• installed packages from requirements.txt, can be done via "pip install -r requirements.txt"
• close MSI Afterburner (if running)

Usage

The tool can be run as-is via the command: "python run.py", it will pick default values for tuning which might not be perfect - but will work. In order to change clocks, it is required to run the executing command line or batch-script with admin privileges (see warning above!).

run.py --mode 2 --devices 0,1,2,3 --fans 70,70,70,70 --steps 5 --shares 3 --datapoints 30 --offset 0.35 --coreUC -200 --memOC 500 --powerLimit 235 --powerCost 0.36 --dollarPerMHash 0.0966

See file "start.bat" for a list of available parameters or see below list:

• --algo <-a>: define which algorithm to mine, default is "ethash"
• --mode <-t>: Defines which optimization mode for power limit should be applied, "--mode 0" (Efficiency) "--mode 1 (Speed)
• --devices <-d>: list of GPUs by id that should be tuned, seperated by commas e.g. "--devices 0,1,2,3"
• --fans <-f>: speed of fans in percentage per GPU, separated by commas e.g. "--fans 70,66,50,80"
• --steps <-s>: stepsize to in/decrease memory and core clocks per run e.g. "--steps 5" will increase or decrease clocks 5 Mhz at a time - lower values increase accuracy of result but take longer time to complete the overall process
• --shares <-x>: number of shares each GPU needs to generate before settings are validated e.g. "--shares 5". More shares increases stability but increases overall process time
• --datapoints <-y>: minimum number of datapoints which are required to compare results e.g. "--datapoints 20". Higher values mean more reliable results. Duration impact is minimal.
• --offset <-o>: to compare speed results e.g. "--offset 0.35". If set too low, your efficiency will suffer. If set too high, the efficiency will be fine but your speed result will suffer, feel free to play with this but 0.35 is a good starting point.
• --coreUC <-c>: starting value of core underclock e.g. "--coreUC -200" will begin the core underclock with -200mhz. Separate values for multiple GPUs with comma e.g. "--coreUC -200,-100,-50"
• --memOC <-m>: starting value of memory overclock e.g. "--memOC 1000" will begin the memory overclock with +1000mhz. Separate values for multiple GPUs with comma e.g. "--memOC 1000, 800, 550"
• --powerLimit <-p>: starting value of power limit e.g. "--powerLimit 240" will begin power limit reduction at 240 watts. Separate values for multiple GPUs with comma e.g. "--powerLimit 240,230,250"
• --powercost <-e>: define how much your power costs $/kWh, needed to calculate profitability in mode 2
• --dollarPerMHash <-i>: define the value of 1 MHash, needed to calculate profitability in mode 2 - you can find out via https://whattomine.com/ - or pick 0.0966 (2020-04-07)
• --loadPreset <-w>: load a preset from the GPU database that is fitting to your cards. If no settings could be found, your provided OC settings (if any) or default values for the OC will be applied (MEM +0 / Core +0/ PL 100% / Fan 70%)
• --miner: define which mining software to use. Default: gminer Supported: gminer, t-rex

Contribution / Donation

By default, running the tool will mine some shares to my wallet address which can be easily changed with a text-editor, but leaving it unchanged would be much appreciated.
