🔥 Lifetime Warranty & Autotuning Option

15% of the TH/s (12% for orders of 10+ miners)

This optional service includes a lifetime hardware warranty and professional autotuning. Each miner is individually tuned using VNish OS based on its own silicon characteristics — no generic profiles.

• Per-machine autotuning
• Lifetime hardware warranty (no expiration)
• Priority support when issues arise
• Replacement parts shipped once a fault is confirmed

How it works: We install specific firmware that automatically allocates 15% of the total 95TH/s per miner for the lifetime warranty service. When an issue is identified, the customer notifies us and we handle resolution directly.

The Antminer S19 95TH/s is a proven SHA-256 ASIC miner built for efficiency, reliability, and scalable Bitcoin mining operations. Each unit comes installed with VNish OS and is professionally autotuned to achieve optimal performance while maintaining long-term stability.

Every miner is professionally refurbished using high-pressure air cleaning, component inspection, Dawn hand-washing, and new fan covers for improved airflow. Each unit completes a full 1-hour stress test before shipment.
