Buying Guide for the Best Motherboards for Ryzen 9 3900X

Going through the reviews will not be enough if you want to get all of the performance out of the CPU. 

You would also have to keep some of the critical factors in your mind. That will increase the chances of you getting the board that can actually make the 3900X soar. And those factors are:

Form Factor

As you know by now, these boards come in mainly four different sizes. One is the regular size, which is the ATX. The other three are MATX, ITX, and Micro ITX. 

When it comes to size, the MATX is smaller than ATX, while the ITX is smaller than the MATX, and finally, Micro ITX is the smallest of all.

Now, we would usually recommend the MATX and ITX boards for compact builds because there will not be too much you would be sacrificing on those boards. But nowadays, Micro ITX boards are also sporting all of the regular ATX boards’ features. But they are a bit expensive.

On the other hand, you would have to consider your chassis. If you already have one purchased, compare the size of the board with the case and get the compatible one.

Chipset

The chipset is the brains of the components that are on the board. It controls the overall state of those parts. 

And when it comes to chipsets, there are three different ones for Ryzen CPUs. The entry-level one is the A-series. 

Those will have good enough features but nothing too extraordinary, making them quite affordable. 

In comparison, the B series boards will have a mixture of the necessary features and some of the enthusiast features. 

The price point of these will be in the middle. Finally, there are X series mobos. Those will have all of the high-end features that one can ever ask for.

Consider your type of workflow and the features that you actually need and make a proper purchase decision for the chipset.

Expansion and PCI-Express Slots

Apart from the chipset, you would also have to consider the number of expansion and PCI-Express slots. The more, the merrier. 

However, the small and compact versions might not have that many of these. But many of them will still have multiple of them.

Nonetheless, do consider the generation of these slots. The current generation is 4.0. And the high-end components are going to offer stellar performance on these slots.

Thermal Solutions

No matter how much of a high-end board you purchase, if it does not have a proper thermal solution, it will not be able to squeeze all the performance out of the Ryzen 9 3900X. 

Instead, there will be thermal throttling, which will make the processor reduce the power draw to compensate for the heat.

That being said, our recommendation here would be to opt for the boards that have extended heat sinks. Also, do consider if there are any physical fans on the board or not. 

Those can keep the temperature of the internal components in check. Also, those boards will be highly capable of making the Ryzen 9 3900X soar.

Connectivity Ports

The I/O ports are pretty important. Usually, the ATX boards are going to have loads of them. But some compact form factor mobos have a comparable amount of ports on the back.

Nonetheless, consider the number of peripherals you want to use. And then get the mobo that has enough ports to run all of them together. 

If you opt for anything that has a low number of ports than what you require, you will need dongles and HUBs. And that would be an extra hassle.

BIOS

Another vital element of the boards is the BIOS. It is basically the place where you will be making the extra adjustments to the entire system. 

And if the BIOS is not adequate, it will be pretty hard to get good overclocking performance out of the Ryzen 9 3900X.

Even if you do not want to get into overclocking now, we would still recommend getting a good BIOS board. Those will have features that you can use to increase the overall performance of the CPU in the future.

RAM Slots and Maximum Capacity

Usually, the ATX boards will have four slots, while the smaller ones might have two or four of them. Nonetheless, one thing that you would have to make sure of is that the slots are in a dual-channel configuration. 

Without being in that configuration, the performance will not be that high in demanding workloads.

Additionally, check the supported Mhz. The Ryzen CPUs benefit a lot from the high-speed sticks. 

In fact, you can get up to 20 to 30 percent more performance if you use RAM that has reasonably high speed. Also, do ensure that the maximum capacity is at least 32 GB.

Frequently Asked Questions (FAQ)

How Much Ram Should I Install in a Ryzen 9 3900X system?

If you are using that CPU, the chances are you run a lot of demanding applications. And those would require at least 16 GB of ram. 
However, if there are four slots on your board, we would recommend installing at least 32 GB of memory. You would future-proof the PC a lot through that.

What Is the Maximum Clock Speed of the Ryzen 3900X?

Without any overclocking, the CPU can boost up to 4.6 GHz. However, that will depend on whether it is getting an adequate amount of power and is appropriately cooled or not. If those two factors are not proper, the CPU might even go below the base frequency.

How Good Is the Ryzen 3900X in Games?

Besides being a good performer in professional workloads, the 3900X is a beast in games. By pairing it with a capable GPU, you would be signing yourself to enjoy a smooth and steady gaming experience even on 4k resolutions. But for competitive games, we would recommend sticking to 1080p or 1440p.

Should I Watercool the Ryzen 9 3900X?

It depends. If you are planning to overclock the CPU, we would recommend opting for a good water cooler. Other than that, the bundled cooler is pretty good at keeping the processor at optimal temperatures.

Does the 3900X Have Integrated Graphics?

No! The 3900X does not have integrated graphics. Only the G series and Pro series of the Ryzen models have integrated graphics.

Final Words

Yes, we covered many models in the best motherboard for Ryzen 9 3900X in the review section. 

But you must keep one thing in mind that each of the models we have reviewed here can make the 3900X run at optimal and sometimes better than the optimal state. 

So, you can pick any of them up without considering your budget, the required features, and the overall form factor. 

However, if we were to recommend one or two, our first pick would be Asus ROG Strix X570-E. It is a stellar board that has all of the latest features. The board even has fast networking solutions.

Our budget pick would be the MSI MPG B550. Even though it is a mid-level board in terms of price, the performance says otherwise. It even flaunts proper RGB lighting support.
