NiceHash Firmware powered by MARA offers several features to keep your ASIC optimized, cool, and stable.
NiceHash Firmware Overclocking
Stock Hashrate: Runs machines at their default hashrate with improved efficiency, simplifying power draw management.
Automatic Tuning allows automatic adjustments based on specific needs:
- Power Target: Limit the farm's power draw by optimizing frequency and voltage automatically to target the desired power draw. (Note: actual power use may vary; higher chip temperatures increase power loss).
- Hashrate Target: Sets a desired hashrate, with minimal power consumption maintained by the Automatic Tuning Algorithm.
- Percentage Adjustment: This option allows increase or decrease hashrate by a desired percentage. Power draw might increase or decrease also.
Fixed Settings: This option allows users to set a fixed frequency and voltage for testing and troubleshooting purposes. It does not perform optimization and may result in lower performance and higher power draw compared to Automatic Tuning.
Sleep Mode: This mode minimizes power usage during planned downtimes, keeping miners accessible for a quick ramp-up when mining resumes.
NiceHash Firmware Environmental Profiles
- Air Cooling: Select this option if the miners are cooled using the pre-installed fans.
- Hydro Cooling: Select this option if the NHFW is running on the Hydro series.
- Single-Phase Immersion Cooling: Select this option if the miners are cooled using typical immersion cooling method.
- Two-Phase Immersion Cooling: Select this option if the miners are cooled by Marathon's Two-Phase Immersion Cooling system.
Intelligent Thermal Protection
Intelligent Thermal Protection (ITP) ensures devices operate continuously, even during extreme temperature changes. This fully automatic feature maximizes uptime by adjusting device temperature.
Here's how it works:
- Temperature Management: Fan speeds adjust to maintain an ideal temperature.
- Overheating Prevention: If temperature exceeds safe limits despite maxed-out fans, ITP underclocks the device to prevent overheating. This can be seen on the Dashboard as "Degraded" status and in the Log.
- Performance Recovery: When temperatures return to safe levels, ITP overclocks the device to restore performance. This is reflected as "Fully Functional" status on the Dashboard and in the Log.
- Extreme Cases: If temperatures are dangerously high, ITP puts the device into sleep mode, indicated by "Sleep mode" status on the Dashboard and in the Log. Miners must be manually restarted after cooling.
This feature ensures higher uptime and performance while protecting hardware. ITP is enabled by default and cannot be disabled.
PDU Integration (TBD)
NiceHash Firmware includes a feature to link smart PDUs with miners for accurate power consumption readings. This feature is currently being tested and will be available soon.
