How to Configure T-Rex Miner for Maximum Hashrate

Optimizing Core Clock and Memory Settings

1. Adjusting the GPU core clock can significantly influence mining performance. A stable overclock enhances processing efficiency without introducing errors during hash calculations.

2. Memory clock tuning plays an equally critical role, especially for algorithms like Ethash that rely heavily on memory bandwidth. Increasing memory speed improves data throughput between VRAM and the compute units.

3. Undervolting the core while maintaining high clocks reduces power draw and heat output, allowing sustained peak operation. Finding the optimal voltage curve prevents thermal throttling.

4. Use tools like MSI Afterburner or AMD Radeon Software to test different configurations before applying them in T-Rex. Stability under load is essential to avoid crashes.

5. Always monitor temperatures during adjustments—exceeding safe limits leads to reduced lifespan and instability in long-term mining sessions.

Configuring T-Rex Miner Command-Line Parameters

1. Launch T-Rex with precise arguments tailored to your hardware. For example, using '--pl' sets power limit directly, ensuring consistent energy delivery across mining cycles.

2. Enable intensity scaling via the '--intensity' flag. Higher values push more work onto the GPU but require balanced cooling solutions to remain effective.

3. The '--kernel' option allows selection of optimized compute kernels. Some kernels perform better on specific GPU architectures, boosting hashrate by minimizing idle threads.

4. Utilize the '--devices' parameter to isolate high-performing GPUs when running multi-card rigs. This enables per-GPU tuning for heterogeneous setups.

5. Incorporate the '--log' flag to generate real-time logs—analyzing these helps identify bottlenecks such as memory errors or dropped shares.

Choosing the Right Mining Algorithm and Pool

1. T-Rex supports multiple algorithms including KawPow, Ethash, and Autolykos. Selecting one aligned with your GPU's architecture maximizes utilization and minimizes inefficiencies.

2. Connect to a low-latency mining pool located geographically close to your region. Reduced ping decreases stale share rates and increases payout consistency.

3. Configure failover pools using the '-r' and '-R' options. Automatic switching ensures uninterrupted mining if the primary server experiences downtime.

4. Enable stratum protocol support with modern pools offering enhanced security and efficient job distribution. This reduces overhead and improves response time to new mining tasks.

5. Avoid overcrowded pools—even with high uptime, network congestion can delay block submission and lower effective hashrate.

Frequently Asked Questions

What does the --mt parameter do in T-Rex?The --mt parameter adjusts memory tweak settings specifically for NVIDIA cards. It modifies memory timings to reduce latency and increase bandwidth, which is particularly beneficial for memory-intensive algorithms like Ethash.

Can I run multiple instances of T-Rex on one machine?Yes, you can launch separate instances targeting individual GPUs. Ensure each instance uses isolated device IDs through the --devices flag and allocates sufficient CPU resources to prevent process contention.

Why is my hashrate lower after a driver update?New drivers may reset overclocking profiles or introduce changes in power management. Reapply custom BIOS settings and verify that memory/controller clocks are running at intended levels post-update.

How often should I benchmark my setup?Benchmark whenever making configuration changes or updating software components. Regular testing ensures that modifications yield measurable gains and helps detect degradation due to wear or environmental factors.
