What is a Motherboard?

Arguably the most important part of a PC, a motherboard, distributes power and allows communication between the RAM, CPU, and all other hardware components. Its base is designed with an incredibly firm sheet of non-conductive material, usually a type of rigid plastic. Thin layers of aluminum foil or copper, also known as traces, are then printed onto the sheet. The traces are incredibly narrow and construct the circuits between the different components. Along with circuits, motherboards also consist of numerous slots and sockets to connect all the other components.

Are All Motherboards The Same?

The advancement of computers has also led to the advancement of motherboards. When it comes to choosing the right model, it’s important to make sure that the unit you choose meets your requirements both today and tomorrow. All motherboards differ in several areas, including:

Chipsets and Sockets 

Different chipsets feature various support combinations of hardware components, like GPUs, RAM, and others. Thus, it’s important to choose a unit with the right socket and chipset for the CPU you plan to build. 

Form Factor

Motherboards are available in different sizes, so users have some flexibility in building their PC according to their environment. A full-size tower case is a better option if you require a lot of space, while a much smaller case may be ideal for a home theater PC you’re planning on placing beneath the family room TV. Moreover, the components a motherboard is able to support will increase with its physical size.

Expansion Options

Along with the CPU, motherboards connect a wide range of components, including networking cards, sound cards, graphics cards, and storage devices and connections. Several different types of expansion ports have been developed over the years, but now, most motherboards are equipped with the Peripheral Component Interconnect Express or PCI-e ports. All in all, motherboards greatly differ when it comes to the placement and number of slots.

How Do I Choose a Motherboard For Ryzen 9 3900x?

With countless models available today, choosing the right motherboard is no easy task. To help you build the best PC, here are some things you should look for before you finalize your purchase:

Memory Overclocking Support

From the first model, Ryzen processors have always relied on Infinity Fabric. This uses memory speed to decrease latency, making it an incredibly important factor to consider when buying any model for AMD Ryzen CPUs. Quality units are usually equipped with an extensive Qualified Vendor List (QVL), which significantly increases your chances of getting the RAM to higher clocks. 

Expandability

Nothing is more frustrating than finding out you’ve run out of storage or memory, and realizing that all the available slots on the motherboard are already maxed out. Make sure you check the number of PCI-E slots, RAM slots, M.2 slots, and SATA ports available on the model you’ve chosen. 

Chipset

The chipset dictates the features you can use with your system. The X570 is one of the best chipsets for Ryzen 9 available today. It’s equipped with extra PCI-E 4.0 bandwidth, enabling users to add ultra-high-speed NVMe storage to their system whenever they want.

What Do I Need To Know Before Buying?

Selecting the best motherboard is arguably the most important part of a PC build. Since every part of the system connects to the board, making the right decision is extremely important. To ensure you don’t end up wasting your money, here are some aspects you should consider before making your purchase:

Size

Most modern motherboards are available in three sizes. ATX is the standard size and provides the largest space for slots and plugs. Micro-ATX is shorter by 2.4 inches and provides less space for expansion slots. Lastly, Mini-ITX is ideal for a tiny PC and only has room for a single add-in card and a few connectors for RAM and storage. 

Number of Ports

Make sure you check the unit’s I/O area and USB headers to see whether it offers the external connection options you want. These enable users to add more ports through a front-panel connection on the PC case, or through expansion slot brackets in the back. 

Number of RAM Ports

Most motherboards available today are equipped with four RAM slots, but high-end HEDT boards offer eight, while compact Mini-ITX models are only designed with two. The number of slots limits the amount of RAM users can install, so make sure you choose the model that best suits your needs.

How to Install a Motherboard

The motherboard may not be the most interesting component of your PC, but it’s certainly the most important. It’s also the largest, which makes it a bit difficult to install. Whether you have an extremely large eATX board, a smaller mATX or ITX, or the conventional ATX, these steps can help make the installation process easier:

1. Hold the motherboard above the back panel to see where standoffs need to be installed. Some PCs may also have them pre-installed. 

2. If needed, tighten the standoffs onto the plate with a standoff tool.

3. Install and fix the rear I/O shield to the back of the case. Make sure you push on every corner to firmly lock the shield in place. 

4. Place the motherboard above the standoffs. 

5. Screw the unit down, but make sure you don’t overtighten it.

6. Install and connect the RAM modules.

7. Connect the CPU power leads and the main ATX power cable. (You can check the PSU and motherboard manual for more details.)

8. Attach the LEDs and front I/O switches, including power and HDD LEDs, speaker, and reset switches. 

9. Connect the fans to the motherboard pins.

10. Install USB, audio, and other case cables to the unit. 

11. Install the SATA HDD or SSD, if you’re using one, by connecting the cables to their respective ports.

12. Insert the GPU in the PCI-e slot and make sure it clicks firmly in place. 

13. Secure the GPU by screwing the component to the back. 

Conclusion

Considering the number of models available today, choosing the best motherboard for Ryzen 9 3900x is no easy task. You can easily get confused with the countless options available and the features they offer. Hopefully, the aforementioned reviews will help you find the model that best suits your requirements!
