5 Best Motherboard for Ryzen 9 3900x [Buyer’s Guide]

Best Motherboard for Ryzen 9 3900x

With the release of Ryzen 9 3900X, AMD is back in business for processors with great value. If you want to buy the best motherboard for ryzen 9 3900x without breaking bank, check out these five options that are just what you need!

Before buying a motherboard to use with Ryzen 9 3900x, consider the below factors: –

The first thing is that you need an AM4 socket board.

If your motherboards are older than two years then it’s high time for an upgrade as AMD has dropped support for old sockets since its new processor series started rolling out in mid-2019.

Secondly, check if your existing memory modules can work along side this CPU or not?

Because some of them don’t support frequencies greater than 2667 MHz and working together will be pointless because only one channel gets full bandwidth while remaining channels get half their potential speed which results in overall performance degradation rather increases latency leading to stuttering during gaming sessions etc.-Finally make sure there’s enough PCIe.

Compatibility with the processor:

It’s not a good idea to buy a motherboard that supports different generations of processors.

You’ll be frustrated if your processor is older than the board you purchase, which will happen in some cases when buying second-generation but third generation motherboards.

Luckily most boards listed on our site work with 1st and 2nd gen CPUs as well!

Expansion Options: 

Once the compatibility with your existing hardware is assured, you should  focus on expanding options.

For example, check how many slots are available for SSDs and graphic cards on the motherboard. The more of each option that’s available, the better!

Chipset & Form Factor: 

Chipsets will decide which hardware components you can  connect and the ones that you can’t.

It is very important for shoppers to make sure they know what chipset their motherboard has before buying it, since chipsets have a huge impact on whether or not some peripherals will be compatible with your board’s form factor.

We have also covered an in-depth “Buyer’s Guide” at the end of the list so that your purchasing decision becomes easier. You can even consider checking out motherboard for ryzen 9 3950x.

Buying Guide 

In this buying guide we have discussed in detail all the things that an user should keep in mind before purchasing a motherboard.

These factors can help you make an informed and better decision about which motherboard best fits the needs of you or someone else who will be using it.

Chipset

When buying a motherboard, it’s important to understand the chipset. A Ryzen 9 3900X won’t work with all motherboards—you need to check for compatibility first!

Form Factor 

A motherboard is a circuit board that includes all the computer’s hardware components.

The form factor is another important consideration when buying your new gaming pc build as different motherboards may not fit into certain cases such as ATX and micro-ATX which are common in most computers today.

The largest and the most popular standard for PC motherboards since its release has been an Intel specification called “ATX” (Advanced Technology eXtended) with dimensions of 12″ x 10″.

This size allows room for expansion cards, but can be tight if you try to use one on top of other items inside so it might require some creativity depending on how much space your cabinet gives you.

There also exists Micro-ATP versions with smaller sizes.

 Compatibility with the processor

It is important to note that not all processors fit with every motherboard.

There are three generations of processors, which include 1st gen, 2nd gen and 3rd gen.

To ensure compatibility between the processor and motherboard you should find out if they belong in same generation or different ones before purchase process begins.

When deciding between the two motherboards, it is important to consider compatibility.

The Asus ROG Strix B450-F supports all three generations of AMD Ryzen CPUs while the MSI MAG B550 TOMAHAWK only supports third generation chipsets.

PCI-e & Expansion Slots

A motherboard with a lot of available expansion slots makes it easier to customize and increase connectivity.

There should be at least one for SSDs, another for graphics cards or sound cards (PCI-E), and 2 more spaces on the board where you can install RAM chips.

Checking out PCI-E slots allows you to attach graphics cards, network adapters or soundcards as well as other devices like external hard drives; this is how we make our computing experience better by using various customized connections.

M.2 Slots

M.2 slots are necessary for a prompt system response and can be found on every motherboard, but it’s better to have more than one.

In the above list of motherboards there is at least one M.2 slot with dual m.2 slots which means you could install multiple SSDs easily in them!

Ports

Since we’re checking out the m.2s port, make sure to check other ports as well! We mean for attaching a keyboard, mouse and any optical devices you’ll need– like an ethernet port too!

Today, motherboards come with multiple USB type C ports and display connections.

HDMI is the new standard for video output so be sure to check if your motherboard supports that instead of VGA or DVI like older models do.

Memory Slots

The above list of motherboards is all compatible with the Ryzen 9 3900x.

When it comes to memory, you want at least four slots on your motherboard so that there’s space for more RAM when upgrading later down the road.

Luckily, every board in this lineup has an impressive amount of memory slot availability; therefore choosing any one will not be a bad decision!

BIOS

The chipset in your motherboard can be updated using BIOS.

Every update will improve the performance of the chipset, so it is important to check whether or not that motherboard supports updating its BIOS before buying it.

Most motherboards support updates but you should double-check by looking at their official website first!

RAM Capacity

When buying a motherboard, check for the RAM capacity first.

The more GBs you can get your hands on, the better it is!

If you’re an average gamer looking to play games at their peak performance levels then opt for 64GB of max support RAM but if hardcore gaming’s what drives your passion than go with 128GB variant instead.

Socket

Your motherboard must support your CPU, so you need AM4 sockets on the motherboards listed above.

The motherboards come with these AM4 sockets which can be used for AMD Ryzen processors that are in 1st through 3rd generations of CPUs

Warranty

Shop for a motherboard that includes warranty.

If there is no information about the product’s warranty, visit its official website to find out more details.

Conclusion

We hope this list helped you in making your decision about which motherboard you should buy.

These were handpicked by us after extensive research and hours of reading about these motherboards on different sites.

The Ryzen 9 3900x is an excellent processor, but it requires a compatible motherboard to get all of its benefits.

If you are on the fence about your budget for this purchase, don’t worry we have compiled our pick of great motherboards that support AMD’s latest flagship CPU.
