Performance
The "Modified Power Supply (LC)" parameter is designed for correct operation of the miner with a modified power supply that supports an extended voltage range.
When this parameter is enabled, the system takes into account the features of the modified power supply and correctly applies voltage settings within the extended range.
This parameter is used only if the power supply has been modified accordingly.
Note
If a standard power supply is used, this parameter should remain disabled.
Function Purpose
The "Preset" function is designed for selecting and managing miner overclocking profiles.
A profile defines a set of hardware parameters, including target power consumption and performance.
Description
The interface provides a list of overclocking profiles, each containing information about:
- estimated power consumption;
- target hashrate;
- profile status (tuned).
The user can select one or more profiles for further use, as well as reset them.
Profile Management
The profile management window allows you to:
- view available profiles;
- select profiles for operation;
- reset selected profiles.
All changes are applied within the current miner configuration.
Note
Overclocking profiles can be used both manually and by the automatic profile switching mechanism if the corresponding function is enabled.
The "Autoswitch presets" function is designed for automatically increasing or decreasing the overclock profile (preset) based on:
- chip temperature;
- power consumption;
- miner stability.
The main goal is to maintain a balance between performance, temperature, and hardware safety without manual intervention.
In addition to automatic adjustment, the firmware provides the option for manual frequency control.
Frequency can be set:
- globally for the entire miner;
- individually for each board (chain);
- individually for each chip.
This feature is intended for users with the necessary technical knowledge and allows manual control of hardware operating parameters.
Function Parameters
If the maximum chip temperature on the miner is below the set value, the system increases the profile (switches to a higher performance preset).
Important:
- the maximum chip temperature is used, not the average;
- the current measurement time is taken into account.
Example:
Value: 66 °C → if the maximum chip temperature < 66 °C → profile increases.
If the maximum chip temperature exceeds the set threshold, the system decreases the profile, reducing thermal load.
Example:
Value: 74 °C → if temperature > 74 °C → profile decreases.
The time during which the system collects and averages metrics before making a decision to switch the profile.
Features:
- lower value → faster response but lower accuracy;
- higher value → more stable decisions but slower response.
Recommended value: 5 minutes
Allowed range: 1–10 minutes
Limits the maximum profile to which the Switcher can increase performance.
Even if the temperature allows — the system will not go above this preset.
Used for:
- power consumption limitation;
- compliance with infrastructure limits.
Limits the minimum profile, below which the Switcher cannot decrease performance.
Prevents excessive hashrate reduction.
Controls the actual power consumption relative to the nominal value specified in the profile.
Can be set:
- in percent (%)
- in watts (W)
Operation Logic:
If actual consumption exceeds the allowed limit → the profile is automatically decreased.
Purpose:
- protection of outlets and PDUs;
- prevention of electrical overload.
If an error or instability occurs while using the current maximum profile, the system:
- automatically reduces the profile to the last stable one;
- serves as a self-recovery mechanism.
Allows the Switcher to ignore fan RPMs when deciding to switch profiles.
Used in scenarios:
- external fan control;
- non-standard cooling systems;
- manual airflow control.
Global voltage defines the voltage level used by the miner within the selected profile.
This parameter:
- is set directly;
- does not have additional nested levels;
- is applied without additional logic.
Global voltage and global frequency parameters are available and applied only when using a tuned profile.
All changes to these parameters are saved exclusively in the configuration of the selected profile.
When operating in profile-disabled mode (Disable), these parameters apply to the entire miner, and settings saved in profiles are not used.
Global frequency defines the base frequency for the entire miner, but its presence does not guarantee that this value will be used by all boards and chips.
Global frequency acts as the top level of the frequency hierarchy and can be overridden by lower-level settings.
All changes to global frequency when a profile is active are saved in the profile configuration, not in the miner’s general config.
Each miner board has its own global board frequency.
Features:
- each board can have its own frequency value;
- a board can use:
- its own frequency;
- or the miner’s global frequency.
If the "use global frequency" option is selected for a board, it takes the miner’s global frequency value.
If a custom value is set — that value is used.
Each chip can have an individual frequency setting.
Options:
- use the board frequency;
- use the global frequency;
- use a custom individual value.
If the "use board frequency" option is selected for a chip, it inherits the frequency of the corresponding board.
If the board uses the global frequency — the chip operates at the miner’s global frequency.
Each miner board has a separate interface for management and data display.
Display Modes
Various display modes can be selected for each board, including:
- hashrate per chip;
- chip errors;
- frequencies;
- thermal map;
- sensor temperatures
The display mode affects only the visual representation of data and does not change hardware operating parameters.
Board Disabling
Each board can be disabled individually.
Depending on the miner model and hardware features, the method to disable a board may vary.
In supported configurations, the board can be disabled directly via the board interface.
In other cases, a separate additional setting is used.
Profile Handling Features
When using profiles, board and chip settings are saved in the profile configuration.
When switching from a tuned profile to the profile-disabled mode (Disable):
- previously set frequencies and voltages are not reset automatically;
- board and chip parameters are preserved in their previous state.
To apply global frequency and voltage values, it is recommended to reset settings for each board manually.
Summary
The overclocking section allows managing miner overclocking both manually and automatically, as well as viewing statistics for each chip (hashrate, frequencies, temperatures, errors).
