What You Get
BiXBiT Prime firmware turns your AMS data into actionable efficiency gains.
Every ASIC tuned automatically.
| Model | Stock J/TH | PRIME J/TH |
|---|---|---|
| S19 XP | 21.50 | 20.20 |
| S19j XP | 21.78 | 20.60 |
| T21 | 18.54 | 17.62 |
| S21 | 17.73 | 16.80 |
| S21 Pro | 14.56 | 13.81 |
| S21 XP | 13.25 | 12.49 |
Lower J/TH = less power per terahash. 5-6% efficiency improvement in BiXBiT internal testing under controlled conditions.
Your results may vary based on hardware condition, ambient temperature, pool configuration, and network difficulty.
BiXBiT Prime Firmware Features
Full-stack optimization for every machine in your fleet.
Autotuning
Per-chip optimization that builds a unique profile for your specific hardware. About 20 to 30 minutes on first boot, roughly 3 minutes on every reboot.
Overclocking
Overclock ceiling up to ~50% above stock, model-dependent. S19 XP and S19K Pro have lower firmware-imposed limits. This is the capability ceiling, separate from the measured 5 to 6% efficiency gain.
Undervolting
Reduce power draw while maintaining hashrate. Lower J/TH means lower cost per terahash.
Profile Switcher
Switch between performance, efficiency, and balanced modes. Saved profiles load in ~3 minutes.
Immersion Mode
Native support for immersion-cooled deployments. Optimized thermal management for liquid environments.
Hotel Fee
Built-in hosting fee management for colocation operators. Automate fee splits at the firmware level.
Firmware Integrity
Built-in firmware integrity verification against unauthorized access and unapproved modifications.
API Access
Full programmatic control. Integrate with your existing management tools and automation pipelines.
AMS Integration
Native connection to BiXBiT AMS. Zero config, full telemetry from the moment you install.
Up to 5-6% Efficiency Improvement
Real numbers from BiXBiT's own production fleet, not a spec sheet.
Measured on our own test fleet.
Six Antminer® models, each tested 8 months to 2 years on BiXBiT Prime firmware. The 5 to 6% efficiency gain reflects BiXBiT internal testing under controlled conditions, not a spec sheet. Results may vary.
Proven at scale on WhatsMiner®. Now optimized for Antminer®.
Cormint runs a 25 MW, roughly 4,600-unit WhatsMiner® deployment on BiXBiT Prime firmware, including ERCOT grid-responsive operation. In curtailment testing, BiXBiT Prime reached fully tuned hash rate in about 4 minutes versus 10 on stock, a 60% cut in switching losses.
Same hashrate target. Optimized power draw. 5-6% efficiency improvement in BiXBiT internal testing under controlled conditions.
Your results may vary based on hardware condition, ambient temperature, pool configuration, and network difficulty.

These are averages across production hardware under real operating conditions, not cherry-picked units in a lab. Your results will vary depending on a number of factors which include chip quality, ambient temperature, and PSU stability. That is exactly why the trial exists: run it on your own fleet and compare.

How the Trial Works
Five steps from request to proof.
Request.
Fill out the form below. Two minutes. Tell us your fleet size and what you're running.
Approval and onboarding plan.
A real person reviews your request and responds with an install plan matched to your fleet, not a download link and a shrug.
Install.
Most operators start with 10 to 20 units to validate, then roll out fleet-wide. Mass remote installation is supported. Our team is available throughout.
First boot.
On first boot the firmware spends approximately 20 to 30 minutes autotuning each unit, learning what every chip can safely do. Mining continues the entire time. After that, reboots return to your saved profile in about 3 minutes.
Measure for 30 days at 0% DevFee.
Watch hashrate, efficiency, and power in AMS. Compare against your stock baseline. Make the call with your own data.
What happens on Day 31?
Your trial converts automatically to the Public Version at a 2.8% DevFee. The fee comes out of mining time, the same model as every aftermarket firmware. Don't want to continue? Revert to stock at any time before or after Day 30. We'll help you do it.
Every install includes BiXBiT AMS
Professional fleet monitoring ships with every BiXBiT Prime firmware install at no extra cost. No competitor bundles anything like it.

Proven at scale, worldwide.
Our U.S. team runs a mixed Antminer® and WhatsMiner® fleet in Texas, and BiXBiT Prime firmware has been proven across large-scale operations worldwide. The product you're evaluating is the one we depend on every day.
On average our switching losses lowered from 10 minutes to 4, which is a 60% reduction in lost revenue.
