Introduction
Overclocking is a popular practice among computer enthusiasts and gamers. It involves modifying the settings of a computer's hardware to increase its performance beyond the manufacturer's specifications. In this article, we will explore the process of overclocking the AMD Ryzen 9 5900 B2 processor. Please note that overclocking may void warranties and can potentially damage the hardware if not done correctly. The information presented here is for informational purposes only and should be approached with caution.
Overclocking the AMD Ryzen 9 5900 B2 Processor
2.1 Entering the BIOS and Basic Settings
To begin the overclocking process, we need to enter the computer's BIOS. This can usually be done by pressing a specific key during the boot-up process. Once in the BIOS, we navigate to the Extreme Tweaker menu. Here, we set the AI Overclock Tuner to DOCP Standard, which enables the memory to run at its XMP-rated DDR4-4266 frequency. We also increase the BCLK frequency to 104, resulting in a roughly 4% increase in the Precision Boost algorithm frequencies.
2.2 Adjusting Precision Boost Overdrive
Next, we enter the Precision Boost Overdrive submenu, where we make the majority of our adjustments. We set the Precision Boost Overdrive to Manual and adjust the PPT, TDC, and EDC limits to increase the power, thermal, and current headroom of the motherboard VRM. We also set the Precision Boost Overdrive Scaler to Manual with a value of 10x, tricking the PBO algorithm into pushing for higher voltages.
2.3 Fine-tuning Curve Optimizer Settings
The Curve Optimizer submenu is where the real magic happens. Here, we can adjust the VF (voltage-frequency) curve for each individual core. By setting a negative curve, we can reduce the voltage required for a given frequency, resulting in lower power consumption, lower temperatures, and increased headroom for higher voltages and frequencies. We test each core individually to find the best Curve Optimizer settings, assigning a negative curve to all cores except Core 2 with slightly different magnitudes.
2.4 Tweaking Voltage and Power Controls
In the External Digital Plus Power Control submenu, we enable Core Voltage Suspension to keep the CPU core voltage within a specific range, even when using dynamic voltage settings like Precision Boost Overdrive. We also set the Co-Mitigator to 0.3, which helps mitigate system instability caused by aggressive Curve Optimizer settings. The Voltage Floor Mode is set to Dynamic, allowing us to configure a custom voltage-temperature curve that adjusts the target voltage range based on the operating temperature.
2.5 Enabling Global C-State Control
In the Advanced menu, we enter the AMD CBS submenu and enable Global C-State Control. This ensures proper frequency scaling when the BCLK frequency exceeds 101 MHz.
Benchmarking and Performance Results
3.1 Comparison to Default Settings
To gauge the effectiveness of our overclocking efforts, we run a series of benchmarks and compare the results to the default settings. In all tests, higher scores indicate better performance. Our findings show significant improvements in performance across the board.
3.2 Analysis of Prime95 Small FFTs Results
We specifically analyze the Prime95 small FFTs benchmark with AVX disabled to assess the impact on effective CPU clock, CPU temperature, VRM temperature, and CPU Package power. Our tests reveal an average effective CPU clock of 4455 MHz at 1.23 volts, an average CPU temperature of 84 degrees Celsius, and an average VRM temperature of 51 degrees Celsius. The highest core clock reported in the operating system reaches 5152 MHz, surpassing the adjusted frequency Ceiling of 4950 MHz.
Conclusion
Overclocking the AMD Ryzen 9 5900 B2 processor can yield significant performance gains when done correctly. However, it requires careful adjustment of various settings such as Precision Boost Overdrive, Curve Optimizer, and voltage controls. It is crucial to approach overclocking with caution and be aware of the potential risks involved.

FAQ:
Q: What is overclocking?
A: Overclocking is the process of increasing a computer's hardware performance beyond the manufacturer's specifications by modifying settings such as voltage, clock frequencies, and power limits.
Q: Is overclocking safe?
A: Overclocking can be safe when done correctly, but it may void warranties and has the potential to damage hardware if not approached with caution. It is important to ensure proper cooling and monitor temperatures during overclocking.
Q: Will overclocking void my CPU warranty?
A: In most cases, overclocking will void the warranty of a CPU. Manufacturers typically do not cover damages caused by overclocking as it is outside the recommended usage parameters.
Q: What are the potential risks of overclocking?
A: Overclocking can result in increased power consumption, higher temperatures, and reduced hardware lifespan if not properly managed. It also carries the risk of system instability and data loss due to inadequate voltage or unstable settings.
Q: Can I use the overclocking settings Mentioned in the article for my system?
A: The settings mentioned in this article are specific to the AMD Ryzen 9 5900 B2 processor and the Crossraid Extreme motherboard used in the demonstration. It is not recommended to directly apply these settings to other systems without proper understanding and consideration of the hardware involved.
