The AMD Ryzen 9 3900X is the most powerful consumer CPU on the market today. It has 8 cores and 16 threads, with a base clock speed of 4.7GHz and a boost clock speed of 5GHz. This processor can handle any game you throw at it, but what type of motherboard should you use to get the best performance?

The best b550 motherboard for ryzen 9 3900x is a type of motherboard that supports AMD Ryzen CPUs. It can be used as a gaming or overclocking board.


AMD’s 3rd Gen Ryzen CPUs are beasts, and the Ryzen 9 3900X is without a doubt the first Ryzen processor to totally beat every Intel and AMD chip in its pricing range. As a result, many fans favor the Ryzen 3900X for productivity and multitasking over Threadripper CPUs and the i9 9900K.


Although the Ryzen 9 3900X has 12 cores and 24 threads, it differs significantly from the Threadripper 2920X in terms of specifications. The 3900X boasts a higher base and boost clock speed of 3.8GHz and 4.6GHz, which is huge for a 12 core CPU, compared to 3.5GHz and 4.3GHz for the 2920X.

The Threadripper CPU costs have fallen considerably since the introduction of the 3900X, but the Ryzen 9 3900X remains one of the most inexpensive ultra high-end processors, with a TDP of just 105 watts. This beast is ideal for all applications, including workstations and gaming, but it is not suggested for gaming alone.

Because this chip may be overclocked, you’ll need to get anything that won’t slow it down. A suitable X570 motherboard for this CPU should feature a robust VRM for intense overclocking, as well as enough heatsinks for cooling. Everything from multiple graphics card setup to numerous fast M.2 SSDs and onboard troubleshooting should be supported. Fortunately, I have mentioned below a few of motherboards that I suggest for this CPU.

Before you purchase, make sure you read everything about them and make up your decision. If you have a different motherboard in mind, feel free to debate it in the comments section below.


AMD Ryzen 9 3900X


GIGABYTE X570 AORUS Elite is a gaming motherboard by GIGABYTE.

Price on


The Aorus Elite from Gigabyte may not be the finest X570 motherboard for the Ryzen 3900X, but it is more than capable of overclocking. This is the finest budget X570 motherboard since it has 12+2 power phases VRM with doublers for overclocking and stability for just $200. The board contains all of the fundamental and advanced capabilities, but it’s not overkill, and you shouldn’t expect it to do everything perfectly. If you are on a limited budget after purchasing your Ryzen 3900X, the next motherboards for this chip are suggested; alternatively, you may look at the following motherboards for this chip.

The board has all of the necessary slots and connectors for adding graphics cards, memory, hard drives, NVME SSDs, fans, and RGB devices, ensuring that your PC may be upgraded in the future. Because it has two M.2 slots, you should certainly use them to speed up your computer. The first M.2 slot, for example, has an aluminum heatsink for heat dissipation, whereas the first PCI-Ex 16 slot has Steel Armor for added robustness. This board features 4x fan headers in total, including the CPU fan header, which should be plenty for a few fans, but if you need more, you can add a splitter or a fan hub to give extra cooling to your chassis since overclocking the Ryzen 3900X would need a lot of airflow.

The only drawback I see with this board is that there are no onboard troubleshooting tools such as Debug LEDs or Power/Reset buttons to quickly resolve a problem, but if you’re familiar with overclocking and troubleshooting, you won’t need them anyway. This board is just $200 and should allow you to construct a good PC with Ryzen 3900X for the least amount of money possible.

When overclocking is a priority, premium motherboards such as the Gigabyte Aorus Ultra should be considered. It features a powerful VRM with 12+2 power phases that use a doubling method for greater overclocking stability. This motherboard is comparable to the Aorus X570 Elite, except it has a “Real” heatsink for overclocking, which is uncommon on other X570 motherboards. Even better, this motherboard is around $300, making it the greatest value for money.

The board features three PCI-E 4.0x 16 slots, two of which are Steel Armor-protected, and can handle up to two Nvidia SLI and two AMD CrossfireX configurations. So, if you want to boost gaming performance, you can absolutely pair two graphics cards with the Ryzen 3900X for insane performance, since the 3900X won’t choke any high-end GPU.

Unlike the Aorus X570 Elite, it includes a total of 6x Fan headers, which is just what you need to power up a large number of fans in your chassis. You won’t need a fan splitter or a hub to enhance the fan quantity. This board also includes an onboard Flash Bios button that allows you to quickly update your BIOS, and it has inbuilt Wifi with two antenna connections that supports 2.4/5 GHz Dual-Band and Bluetooth 5.0.

It features 6 SATA ports and 3 M connectors for storage. There are two slots, each with aluminum heatsinks, which is what you should anticipate for efficient cooling. I do not think that the Aorus X570 Ultra is a bad board for Ryzen 3900X, but rather that it is one of those boards that will provide performance comparable to premium boards costing hundreds of dollars and will not let you down. However, Gigabyte should have included inbuilt troubleshooting tools to make it the greatest value.


Taichi ASRock X570

Price on

ASRock X570 Taichi

For the Ryzen 7 3700X and Ryzen 3900X, I suggest the ASRock X570 Taichi, which is a great board for overclocking. The board includes 8+4 CPU power connections to provide adequate power to allow you to overclock your CPU without difficulty, but the 3900X is unlikely to utilize the other 4 pin connector due to its low TDP of just 105 watts.

The VRM on this board uses doublers to provide 12+2 power phases, while the heatsink on both sides uses copper tubing for heat transmission. This is what you’ll need for excellent overclocking and stability, but the Gigabyte Aorus X570 Ultra, in my view, has a superior aluminum heatsink. On its VRM, this board has 60Amp power chokes, which are more stable in overclocking than the 40A chokes used on typical boards. As a result, it’s an excellent option for boosting performance.

Fortunately, the board has Dr. Debug, which includes an LED that shows the post code and aids in detecting issues with the attached devices. This function is not available on the Gigabyte Aorus X570 Ultra, which is extremely helpful for overclocking and experimenting. This board also has Reset, Power, and a Clear CMOS Button, which will make experimenting much easier.

This board’s design is likewise amazing, and the mechanical design on the shrouds and heatsinks looks too nice. If you’re spending $300 on a board, don’t expect it to be without WiFi. It is equipped with an Intel 802.11ax WiFi Module that supports IEEE 802.11a/b/g/n/ax and Dual-Band (2.4/5 GHz) Bluetooth 5.0. In my view, these characteristics should be plenty for the Ryzen 3900X, but if you want even greater performance, try the following choice.


Hero ASUS ROG X570 Crosshair VIII (Wi-Fi)

Price on

ASUS ROG X570 Crosshair VIII Hero (Wi-Fi)

Asus produces the finest motherboards in general, whether they are low-cost or high-end. Asus Crosshair series boards are designed specifically for overclocking, and with that in mind, Asus launched the X570 Crosshair VIII Hero Wifi, which is almost as excellent as boards that cost more than $500 but costs less than $400. Going above and beyond this board, in my opinion, will not provide greater outcomes and will instead waste your money.

This board has the greatest VRM, with 14+2 power phases (really 7+2), and it can overclock the Ryzen 3900X better than any of the other motherboards. This alone makes it worthwhile to purchase, but don’t forget about the other aspects you shouldn’t overlook. Safe boot and Reset buttons, Slow mode for LN2 cooling, LED Display for post codes, Power and Retry buttons are among the onboard troubleshooting options. It has a Clear CMOS and a Bios Flashback button on the back, allowing you to quickly reset or update your BIOS.

This board includes 11 headers for chassis fans, water cooling, CPU fan, and AIO cooling, which are uncommon on motherboards, but make sense on this one since it is designed for advanced overclocking using either a bespoke water loop or Liquid Nitrogen cooling. If you don’t want to use either, you need at the at least use AIO cooling for Ryzen 3900X on this board, otherwise you won’t be able to take use of all of its features. It is, in my opinion, the greatest fit for the Ryzen 3900X, and going higher would not offer you with additional value.



Because the Ryzen 3900X is a super-high-end board from AMD that competes with Threadripper CPUs and outperforms all previous high-end mainstream CPUs, it can only be fully used with a board designed for sophisticated overclocking. Some of the boards mentioned at the top of the page are compatible with it, although they may not be able to optimize its performance. Getting something like the ASRock X570 Taichi or the Asus ROG X570 Crosshair VIII Hero will be well worth it if you truly want to get the most bang for your buck.


The best motherboard for ryzen 9 3900x under $200 is a motherboard that can be used with an AMD Ryzen 9 3900X processor. It’s one of the best motherboards for this processor, but it’s also affordable.
