How to set up T-Rex miner for maximum performance?

Hardware Compatibility and Driver Optimization

1. Ensure your GPU model is supported by the latest stable release of T-Rex miner—NVIDIA cards from the Pascal, Turing, and Ampere architectures deliver optimal hash rates for Ethash and KawPow algorithms.

2. Install the most recent NVIDIA Game Ready driver compatible with your Windows or Linux distribution; avoid data center drivers unless explicitly validated for mining workloads.

3. Disable Windows Hardware Accelerated GPU Scheduling and set GPU power limits manually via MSI Afterburner to prevent thermal throttling during extended runtime.

4. Confirm PCIe slot configuration: use x16 slots directly connected to the CPU, not chipset lanes, to maintain full bandwidth for memory-intensive DAG file transfers.

Configuration File Tuning

1. Create a dedicated config.json file instead of relying solely on command-line arguments to preserve consistency across restarts and updates.

2. Set --gpu-init-mode 1 to initialize all GPUs in parallel rather than sequentially, reducing startup latency on multi-GPU rigs.

3. Use --lhr-tune values calibrated per-card based on observed LHR unlock thresholds—not generic presets—to sustain stable core clocks above 1800 MHz on RTX 30-series cards.

4. Enable --watchdog-disable only after verifying system stability; otherwise, retain watchdog to auto-restart hung processes without manual intervention.

Thermal and Power Management

1. Maintain ambient room temperature below 24°C and ensure unobstructed airflow through GPU heatsinks using static pressure fans oriented for direct intake on riser-mounted cards.

2. Flash custom VBIOS versions verified for mining efficiency—such as MSI Gaming X Trio BIOS mods—that lower voltage curves at medium clock offsets without sacrificing stability.

3. Monitor VRAM junction temperatures using nvidia-smi -q -d TEMPERATURE; sustained readings above 95°C indicate insufficient cooling or excessive memory overclocking.

4. Apply undervolting profiles that reduce core voltage by 80–120 mV while preserving memory clock at factory spec to maximize power-per-hash ratio.

Pool Selection and Connection Stability

1. Choose pools offering low stale share rates and sub-100ms average ping times—Ethermine and 2Miners consistently report under 0.3% stale rate for Ethereum Classic and Ravencoin mining.

2. Configure dual pool failover using --failover-only to redirect hashing automatically if primary pool becomes unreachable for more than 30 seconds.

3. Avoid public proxy-based stratum endpoints; instead, connect directly to regional pool servers like us-west.ethermine.org or eu1.2miners.com to minimize network jitter.

4. Set --retry-pause 5 to prevent aggressive reconnection loops that may trigger IP-based rate limiting on some pool infrastructures.

Frequently Asked Questions

Q: Does T-Rex support AMD GPUs?A: No. T-Rex miner is built exclusively for NVIDIA CUDA-enabled devices and does not include OpenCL or ROCm backend support.

Q: Why does my RTX 4090 show significantly lower hashrate than advertised benchmarks?A: Factory-overclocked models often require manual memory timing adjustments using tools like GPU-Z to unlock full GDDR6X bandwidth; default BIOS settings commonly limit effective memory speed to 21 Gbps instead of 23.4 Gbps.

Q: Can I run T-Rex alongside other CUDA applications like TensorFlow training jobs?A: Concurrent execution is unsupported and will result in device contention errors; T-Rex requires exclusive access to GPU compute resources during active mining sessions.

Q: Is it safe to enable --auto-fan in production environments?A: Not recommended. The built-in fan control lacks hysteresis tuning and may cause rapid oscillation between 40% and 80% fan speeds under variable load, accelerating bearing wear over time.
