Troubleshooting the Display GPU Cable Issue

The first challenge we encountered in our mining journey was using the wrong cable for our display GPU. In order to rectify this issue, we decided to try a mini HDMI to USB-C cable. Finding a mini to mini cable was proving to be nearly impossible, so this alternative seemed promising. We connected the cable and eagerly awaited the results.

Testing Mini HDMI to USB-C Cable

We tested the mini HDMI to USB-C cable by running the 5950xt XMP with a slight voltage increase from 0.9 to 0.95. Our aim was to determine if this adjustment would have any impact on the hash rate. However, to our disappointment, we observed that it only added an additional 10 watts to the power consumption without improving the hash rate. This led us to believe that running the GPU at a 35 ratio and 0.9 volts was the optimal configuration.

Adjusting Voltage for Improved Hash Rate

In our pursuit of maximizing hash rate, we experimented with voltage adjustments. We found that increasing the voltage from 0.9 to 0.95 did not yield any significant improvements in hash rate. In fact, it only resulted in a 10-watt increase in power consumption. It became evident that running the GPU at a 35 ratio and 0.9 volts was the most efficient and stable configuration. However, we haven't completely ruled out the possibility of further tweaking the settings for marginal gains.

Stability and Efficiency Considerations

As with any mining operation, stability and efficiency are crucial factors to consider. While some miners push their GPUs to their limits, we believe in prioritizing efficiency and stability over chasing higher hash rates. We were initially hoping to achieve a hash rate of 18 with a power consumption of 140 watts. However, it became clear that such a configuration would result in excessive power consumption, potentially compromising stability. Therefore, we settled for a hash rate of 15 at 147 watts, focusing on optimizing the efficiency of our mining rig.

Pros:

• Emphasizing stability and efficiency leads to reduced power consumption and potentially longer lifespan of the GPU.
• Lower power consumption translates to lower electricity costs, increasing overall profitability.

Cons:

• Sacrificing potential higher hash rates may limit the overall mining revenue.

Review of Thermalright Purist Assassin Cooler

Throughout our mining journey, we have come across various cooling solutions for GPUs. One cooler that stood out for us was the Thermalright Purist Assassin. This cooler, particularly the Assassin 120 model with its four heat pipes, provided excellent performance and temperature management for our 5950x GPU. Even while pulling 147 watts, we observed no alarming temperature readings. This reassured us about the effectiveness and reliability of the cooler in maintaining optimal operating temperatures for our mining rig.

Optimizing Thread Allocation for CPU Config

In our Quest for maximizing mining efficiency, we also experimented with thread allocation for our CPU configuration. We discovered that using a specific CPU thread command that skips the Second thread and the last thread resulted in improved mining performance. By utilizing this configuration, we were able to achieve a higher hash rate compared to utilizing all the available Threads. This finding demonstrates the importance of fine-tuning CPU settings to optimize mining operations.

Hash Rate and Wattage Measurements

In order to accurately assess the performance of our mining rig, we conducted hash rate and wattage measurements. With the 5950x running at a 37 ratio and 0.9 volts, we achieved a hash rate of 17. At the wall, the wattage reading showed 150 watts. This represented a modest increase in power consumption for a marginal gain in hash rate. Despite this, we considered it worth the trade-off as it contributed to the overall efficiency of our mining operation.

Upgrading and Configuring the System

To further enhance our mining rig, we decided to integrate a 7900x alongside the 5950x. This required reconfiguring the system and ensuring proper power allocation. We utilized a Pico PSU connected to a six-Pin connector to power the motherboard. Additionally, we used a PCIe to EPS converter to supply dedicated CPU power from the breakout board. These modifications ensured stable and efficient power distribution within the system, ultimately improving its overall performance.

Conclusion

In conclusion, our mining journey has been a series of discoveries, optimizations, and trade-offs. By troubleshooting cable issues, testing alternative solutions, adjusting voltages, and prioritizing stability and efficiency, we were able to maximize the performance of our mining rig. The Thermalright Purist Assassin cooler proved to be a reliable solution, effectively managing temperatures. Optimizing thread allocation for the CPU configuration further boosted mining performance. Through hash rate and wattage measurements, we gained valuable insights into the efficiency of our system. With upgrades and proper configuration, we continue to fine-tune our mining rig for optimal performance. Thus, we have experienced the exciting and ever-evolving landscape of GPU mining firsthand. Happy mining!
