Not using OCTune yet? Click on the button below to download QuickMiner and try OCTune. You can read how to use OCTune here.

Redesigned OCTune is only available on QuickMiner v0.5.4.4.0 RC and newer versions.

What is NiceHash OCTune?

NiceHash OCTune is a web interface that communicates with NiceHash QuickMiner and is used to modify:

• Fan profiles, 
• Core clock, 
• Memory clock,
• TDP, 
• Voltage,
• Memory timings of your GPU. 

Additionally, Autotune allows you to find the best core clock for your memory clock settings. You can find more information about Autotune below. 

How to start OCTune?

Once you downloaded and installed NiceHash QuickMiner simply navigate to the system tray and right-click on the NiceHash QuickMiner icon then select OCTune as shown in the picture below.

1. Information Panel

Here you can see the general information about the status of the mining. 

• See how many devices are mining.
• Total speed of all devices.
• Total power consumption.
• The efficiency of mining devices that is calculated by dividing speed by power.
• Highest temperature readings.

---

2. History Graph

Here you can check past 30 minute data of your devices. You can hide the data lines by clicking on them in the graph menu.

Each event on the overclocking panes (6) will be seen on the graph. This will help you see the status of your devices before and after overclock.

You can zoom in the graph by click-and-dragging on the graph.

3. Excavator Status

Here you can find basic information about the hardware and its current status. Most of them are self-explanatory.

• Utilization - the usage of your GPU and Memory. Should be 100% if you are mining with full power.
• Fan - Fan speed in absolute values (RPM) and in percentages.
• Fan Setting - Shows what fan settings is the GPU currently using.
• Core - current absolute value of core clock.
• Core Limit - the highest allowed absolute core clock. Can be changed in Alternative method for overclocking(6). 
• Core Volt. - current core voltage. You can also lock the voltage in Alternative method for overclocking(6). 
• Selected - If you want to overclock more GPUs at the same time, you can select the checkbox at the far right and click the Selected button when applying settings.
• Prefill - This button prefills the data on the overclock and fan tab on the right side (6).

4. Excavator OC Tuner

The next table shows Excavator OC Tuner. This is the data that is received from Excavator. Here you can examine:

• MIN KT - Minimal  Kernel Time. Execution time of code running on GPU in microseconds.
• AVG KT - Average kernel Time.
• UMed KT - Upper median (¾) Kernel Times. Your goal is to get this value as low as possible.
• HW err - Rejected shares due to high memory clock. This should be 0. Lower memory clock to eliminate HW err. 
• HW ok - Accepted shares.
• Core Delta - Increased or decreased value from stock core clock.
• Mem Delta - Increased or decreased value from stock memory clock.
• Power Real (W) - Power usage of GPU in Watts. Includes all power draw sensors available.
• Eff. (kH/J) - Efficiency of mining. Speed divided by power draw.

5. Event Log

Here you can track the events and errors. If something does not go as planned, check this for additional information.

6. Preferences

Here you can control your devices. Preferences window includes:

• General options - Change refresh rate or reset overclocks and fan profiles here.
• Profiles - Is used to modify the existing profiles.
• Overclocking - The most important tab. Set classic (offset/delta) or alternative (absolute) values here.
• Fan - Set fan profiles here. You can select different fan modes.
  • Default/Auto - No changes to the fan profile.
  • Fixed speed - Set a fixed fan speed.
  • Target GPU Temp - Fan will be adjusted relative to the specified GPU temperature.  
  • Target GPU&VRAM/HotSpot T. - Similar as above. Additionally, the fans will be also adjusted to VRAM or HotSpot temperature.
  • Target plus decrease MCC - Same as target GPU&VRAM/HotSpot T. but if the fans alone will not be able to cool down the GPU, the memory core clock will slowly drop until the target temperature is reached.

• Autotune - Autotune automatically finds the best locked core clock for a specified absolute memory. 

Note that due to API limitations of NVIDIA management libraries, Alternative OC and Autotune features are available only for the RTX series (2000 and 3000).
