Question:

How can I achieve higher boost frequencies on my 5800X3D CPU in an Asrock X570 PG ITX/TB3 motherboard? >
> I have a new ITX build with a 5800X3D CPU, a Phantom Spirit SE cooler, and a 1100W PSU. I updated the bios to the latest version and installed the latest AMD chipset drivers. I tried various settings for PBO, PPT, EDC, and TDC, but the CPU never boosts above 4.05 GHz, even though the temperature is below 72 C.

How to Boost Your 5800X3D CPU Performance in an Asrock X570 PG ITX/TB3 Motherboard

The 5800X3D is a powerful CPU that can deliver impressive performance in gaming and productivity applications. However, some users may encounter issues with low boost frequencies, especially in ITX builds with limited cooling and power delivery options. In this article, we will explain the possible causes of this problem and how to fix it.

Boost frequency is the maximum speed that a CPU can reach under optimal conditions, such as low temperature, high power, and light workload. Boost frequency is not a constant value, but rather a dynamic one that depends on various factors, such as the number of active cores, the CPU voltage, the motherboard settings, and the CPU cooler.

Boost frequency matters because it directly affects the performance of the CPU and the overall system. Higher boost frequencies mean faster processing of tasks and smoother gaming experience. However, higher boost frequencies also mean higher power consumption and heat generation, which can limit the potential of the CPU.

What are the Possible Causes of Low Boost Frequency?

There are several possible causes of low boost frequency on the 5800X3D CPU, such as:

• Insufficient cooling: The 5800X3D is a hot CPU that requires adequate cooling to maintain high boost frequencies. If the CPU cooler is not powerful enough, or the airflow in the case is poor, the CPU will overheat and throttle its speed to prevent damage. The Phantom Spirit SE is a decent cooler, but it may not be enough for the 5800X3D in an ITX case with limited space and ventilation.
• Inadequate power delivery: The 5800X3D is also a power-hungry CPU that requires sufficient power delivery from the motherboard and the power supply unit (PSU) to sustain high boost frequencies. If the motherboard VRM (voltage regulator module) is not robust enough, or the PSU is not stable enough, the CPU will not receive enough voltage and current to operate at its full potential. The Asrock X570 PG ITX/TB3 is a good motherboard, but it has a relatively small VRM with only six phases, which may not be enough for the 5800X3D under heavy load. The 1100W PSU is more than enough for the system, but it may not be of high quality or efficiency, which can affect the stability and reliability of the power delivery.
• Improper BIOS settings: The BIOS settings can also affect the boost frequency of the CPU, such as the PBO (Precision Boost Overdrive), PPT (Package Power Tracking), EDC (Electrical Design Current), and TDC (Thermal Design Current). These settings control the power and thermal limits of the CPU, as well as the overclocking potential. If these settings are too low, the CPU will not be able to boost beyond a certain point. If these settings are too high, the CPU will consume more power and generate more heat, which can also limit the boost frequency.

How to Fix Low Boost Frequency?

There are several possible solutions to fix low boost frequency on the 5800X3D CPU, such as:

• Upgrade your cooling system: The most effective way to improve the boost frequency of the CPU is to upgrade your cooling system. You can either replace your CPU cooler with a more powerful one, such as a liquid AIO (all-in-one) cooler, or improve the airflow in your case by adding more fans or removing unnecessary obstructions. This will lower the temperature of the CPU and allow it to boost higher and longer.
• Optimize your power delivery system: Another way to improve the boost frequency of the CPU is to optimize your power delivery system. You can either replace your motherboard with a more capable one, such as a X570 or B550 board with a larger VRM and better heatsinks, or replace your PSU with a more reliable one, such as a 80+ Gold or Platinum rated unit with high-quality components and cables. This will increase the voltage and current delivery to the CPU and enable it to operate at its full potential.
• Adjust your BIOS settings: The final way to improve the boost frequency of the CPU is to adjust your BIOS settings. You can either enable PBO and let the CPU automatically overclock itself based on the available power and thermal headroom, or manually tweak the PPT, EDC, and TDC values to find the optimal balance between performance and efficiency. You can also try to update your BIOS to the latest version, which may include improvements and fixes for the CPU performance.

Conclusion

The

5800X3D is a great CPU that can offer amazing performance in ITX builds, but it may suffer from low boost frequencies due to various factors, such as cooling, power delivery, and BIOS settings. By following the steps above, you can fix this problem and enjoy the full potential of your CPU. However, keep in mind that every system is different and your results may vary depending on your hardware and software configuration. Always monitor your CPU temperature, voltage, and frequency, and test your system stability and performance before and after making any changes. Happy boosting!
