Introduction

Welcome to the Rabid Mining YouTube Channel! In this video, we will be taking a deep dive into the optimal settings for the AMD Ryzen 9 3900X CPU when mining the Pulsar cryptocurrency. Our goal is to find the best hash to watt ratios for maximizing mining efficiency. So, let's get started!

About the Ryzen 9 3900X CPU

The Ryzen 9 3900X is a powerful CPU with a base clock of 3.8 GHz and the ability to boost up to 4.6 GHz. It features 12 cores and 24 Threads, making it an ideal choice for CPU mining. In our testing, we will be using a X470 MSI Gaming Max motherboard, Kingston M.2 SSD drive, G-Skill Flare CL14 RAM, and an EVGA 750W PSU.

Testing Setup

Before we dive into the optimal settings, let's take a look at our testing setup. We are using a headless configuration, meaning we don't have a GPU connected for display purposes. The mining process is being monitored and adjusted through the BIOS and Hive OS. For display and Recording purposes, we have a Gigabyte GTX 670 2GB GPU and a capture card connected to a separate monitor.

Finding the Optimal Settings

We conducted a series of tests, gradually increasing the CPU clock speed from 3.6 GHz to 4.5 GHz. At each clock speed, we tested different RAM configurations and noted the hash rates, power consumption, and temperatures. Let's go through the results step by step.

4.1. Testing at 3.6 GHz

With the CPU clocked at 3.6 GHz and a voltage of 0.95V, we tested various RAM configurations. Surprisingly, we found that using a single stick of RAM without any overclocking resulted in the best hash to watt ratio. This configuration produced a hash rate of 64.52 kH/s at only 83W, making it the most efficient setting.

4.2. Testing at 3.7 GHz

Continuing our tests at 3.7 GHz, we saw a similar trend. The most efficient configuration remained the same: a single stick of RAM without any overclocking. This configuration yielded a hash rate of 68.19 kH/s at 86.2W.

4.3. Testing at 3.8 GHz

At 3.8 GHz, the voltage remained at 0.95V. Again, the most efficient configuration was using a single stick of RAM without any overclocking, giving us a hash rate of 71.75 kH/s at 87.6W.

4.4. Testing at 3.9 GHz

As we increased the clock speed to 3.9 GHz, we were amazed to find that the CPU remained stable at a low voltage of 0.95V. The most efficient configuration, once again, was a single stick of RAM without any overclocking, producing a hash rate of 69.96 kH/s at only 87.6W.

4.5. Testing at 4.0 GHz

To achieve a clock speed of 4.0 GHz, we slightly increased the voltage to 1V. As expected, using a single stick of RAM without overclocking proved to be the most efficient configuration, with a hash rate of 69.96 kH/s at 87.6W.

4.6. Testing at 4.1 GHz

Continuing our tests at 4.1 GHz, we further increased the voltage to 1.05V. The trend persisted, with a single stick of RAM without any overclocking offering the best hash to watt ratio. This configuration resulted in a hash rate of 69.96 kH/s at 87.6W.

4.7. Testing at 4.2 GHz

Moving to 4.2 GHz, we bumped up the voltage to 1.05V. Again, using a single stick of RAM without any overclocking proved to be the most efficient configuration, yielding a hash rate of 69.96 kH/s at 87.6W.

4.8. Testing at 4.3 GHz

At 4.3 GHz, we maintained the voltage at 1.05V. The configuration with a single stick of RAM without any overclocking continued to be the most efficient, resulting in a hash rate of 69.96 kH/s at 87.6W.

4.9. Testing at 4.4 GHz

As we reached 4.4 GHz, we observed that the efficiency started to decline. The most efficient configuration was still a single stick of RAM without overclocking, but the power consumption increased to 96.6W while producing a hash rate of 78.93 kH/s.

4.10. Testing at 4.5 GHz

Finally, at 4.5 GHz, we saw a further decrease in efficiency. The most efficient configuration continued to be a single stick of RAM without overclocking, but the power consumption rose to 145.6W while achieving a hash rate of 78.93 kH/s.

The Impact of RAM on Hash Rates

In our testing, we compared the performance of CL 14 RAM and CL 16 RAM. Surprisingly, there was very little difference between the two. The hash rates were nearly identical, with only a slight increase in power consumption for the CL 16 RAM. This suggests that opting for the more affordable CL 16 RAM can be a cost-effective choice without sacrificing performance.

Conclusion

Based on our extensive testing, we have found that the Ryzen 9 3900X CPU performs optimally when using a single stick of RAM without any overclocking. This configuration consistently achieved the highest hash to watt ratios, resulting in efficient mining for Pulsar and other similar cryptocurrencies. Additionally, our tests showed that CL 16 RAM can provide nearly identical performance to CL 14 RAM at a lower cost.

It's important to note that these findings are specific to the Pulsar mining algorithm. Different algorithms may require different settings for optimal performance. As always, it's recommended to do your own research and experiment to find the best settings for your specific mining needs.

Thank you for watching, and happy mining!
