🎯 Introduction

In this article, we will explore the viability of using a cheap motherboard for overclocking a powerful CPU like the AMD Ryzen 9 3900X. The high prices of X570 motherboards have led many enthusiasts to consider cheaper alternatives, such as B350 or B450 motherboards. However, there are concerns about the potential issues and limitations that may arise from using these budget-friendly options. We will analyze the performance, thermals, and overclocking potential of cheap motherboards in comparison to their more expensive counterparts. Let's dive in!

🔍 The Viability of Using a Cheap Motherboard for Overclocking

The cost of X570 motherboards can be quite prohibitive for some users, especially when compared to the more affordable B350 or B450 options. This raises the question: Is it possible to safely overclock a high-end CPU like the 3900X on a budget motherboard? Can we expect similar performance and stability without breaking the bank? In this section, we will investigate the potential advantages and drawbacks of opting for a cheaper motherboard.

⚠️ Potential Issues with Cheap Motherboards

While using a cheap motherboard for overclocking may save you some money upfront, there are potential downsides to consider. One primary concern is the overheating of the motherboard's VRM (Voltage Regulator Module), which is responsible for supplying power to the CPU. Cheaper motherboards often have less robust VRM designs, which can lead to higher temperatures and potential instability under heavy overclocking loads. Additionally, cheaper motherboards may not reach the same level of overclocking performance as their more expensive counterparts, limiting the full potential of the CPU.

🔄 Comparison between X570 and X470 Motherboards

Contrary to expectations, X570 motherboards differ significantly from their predecessors, the X470 boards. These newer motherboards appear more like behemoth Threadripper boards at first glance, showcasing enhanced features and power delivery capabilities. However, not all users require these extravagant features. By saving money on the motherboard, you can allocate those funds towards upgrading your CPU or GPU. Nevertheless, this choice raises concerns about potential overheating and overclocking limitations. In the following sections, we will delve deeper into these issues.

💻 The ASUS B350-F Strix Motherboard

To explore the viability of using a cheap motherboard for overclocking, we will focus on the ASUS B350-F Strix motherboard. While it is one of the more expensive B350 motherboards available, it still falls within the affordable range. This motherboard features a relatively average VRM design, consisting of a four plus two-phase VRM. The VRM phases comprise one high-side and two low-side MOSFETs, which is fairly typical for most B350 motherboards. However, compared to the majority of X570 motherboards, the VRM design of the B350-F Strix is notably less robust.

🌡️ VRM and Thermals: Testing on Different Motherboards

To assess the thermal performance of the ASUS B350-F Strix motherboard and compare it to other options, we conducted a test using different motherboards, including the X570 Horus Pro Wi-Fi and the X570 Aorus Extreme. Running the AMD Ryzen 9 3900X at stock settings, we monitored the VRM and CPU temperatures after 20 minutes of rendering a scene in Blender. The results revealed that the B350 motherboard ran the warmest, albeit within acceptable limits. However, the X570 motherboards demonstrated greater thermal efficiency, thanks to improved VRM designs and superior heat dissipation.

⚡ Overclocking the 3900X on Cheap Motherboards

When it comes to overclocking potential on the ASUS B350-F Strix and similar motherboards, we aimed to push the limits of the 3900X. Managing to achieve a stable overclock of 4.4 GHz on the X570 motherboards, we attempted the same on the B350 motherboard. Surprisingly, with slightly higher voltage, we were able to attain the same performance. However, it is crucial to note that higher voltages resulted in increased power draw and thermals for both the CPU and VRM. These factors need to be considered for a manual overclock.

🔢 Memory Overclocking on the B350 Motherboard

Apart from CPU overclocking, memory overclocking is another critical aspect to consider when using a cheap motherboard. Unlike X570 motherboards, which generally support XMP (eXtreme Memory Profile) for easy memory overclocking, B350 motherboards may require manual tweaking of timings. In our testing, we successfully achieved stability on the B350-F Strix motherboard by loosening the timings from CL14 to CL15 on a 3200 MHz memory kit. While requiring some extra effort, it is still possible to achieve satisfactory memory overclocking on cheaper motherboards.

💸 The Need for Expensive Motherboards

The release of X570 motherboards with high phase VRMs and impressive features may lead individuals to believe that these premium options are necessary for running the 3900X. However, our testing proves that a typical B450 or X470 motherboard is more than capable of supporting the CPU. With proper VRM analysis and adequate case airflow, users can safely overclock the 3900X on a cheap motherboard without compromising performance or stability. Investing in an expensive motherboard should only be considered if you require specific advanced features or plan to heavily overclock.

🎉 Conclusion

In conclusion, our testing indicates that it is indeed possible to use a cheap motherboard, such as the ASUS B350-F Strix, for overclocking the AMD Ryzen 9 3900X. While budget motherboards may have some limitations, such as VRM design and cooling capabilities, they can still provide a viable option for users seeking cost-effective solutions. By carefully considering the VRM quality and thermals, individuals can confidently opt for a B450 or X470 motherboard and allocate their funds towards other essential components like the CPU or GPU.
