Tips For Buying Ryzen 9 3900x Motherboard
Selecting motherboard is the most important part of a PC build. Although the above is a complete review and guide on best Best Motherboard for Ryzen 9 3900X in 2023 and now, hopefully, you are able enough to buy the best product as per your choice, some of you are still confused about choosing a product. The Ryzen 9 model of 3900X is a 12-core processor, which shocks the competition between Ryzen 9 3900X and Intel Core i9 processors. It’s powerful enough for high-end uses like video editing and playing AAA game titles, but it needs an equally capable motherboard. So, to help you out, we decided to make a list of the most important features that you, as the buyer, should consider before making the purchase.
Compatability of Processor
The first and the essential factor you should know is the compatibility of the processor with this motherboard. Processors come up with different generations, that is, the versions. You must know about it well. Every generation has no support with every motherboard. Every one of you knows that there are different processors, including Gen 1, Gen 2, and Gen 3, and more. So, it depends on which one you want to buy. After your choice and analysis, look for a motherboard that is compatible with your processor. Some motherboards including the ASUS brand and some MSI brand products, can support all processors of a certain generation.
Many users look for high memory, and some, on the other hand, don’t require high memory. So, it depends upon your need and which memory support you need for daily tasks. Some motherboards can support high memory of more than 32GM RAM, and some, on the other hand, have a short memory of less than 32GB RAM. You can check motherboards of qualified vendor lists for the sake of your confidence and assure the best quality. In other words, you can say that RAM capacity is an essential factor to consider.
Sockets & Chipsets
Some of the motherboards lack a couple of slots like RAM expandability, NVMe SSD slots, etc. If you are looking to get hold of SSDs and a pair of extra RAMs, make sure your motherboard has the option for slotting in more components. The other most important and vital feature is the chipset of a motherboard which determines how fast or slow your performance can be based on RAM, GPU, and Many other attachments with this device. Moreover, the chipset enables different features in the overall experience like Resizable Bar, Fast Boot, and Overclocking support.
It’s another important factor that needs to be addressed. There are three kinds of factors: ATX, Micro ATX, and Mini ATX. The most common one is the ATX form factor which comes in different sizes based on the number of DIMM slots available for memory. If you are replacing your old motherboard and don’t know the exact size, you can always measure the old one and get the one with the same size for accuracy purposes. If you bought a standard ATX, but your case only supports mini ATX, what will you do? Possibly, nothing! Your money is down the drain. So, it is required for you to select only those motherboards which are hostable in your case.
Expansion Slots & PCIe
A good gaming PC will require more than just a processor, graphics card, and ram. The ATX format is recommended because of its large number of expansion slots, and this makes upgrading easier down the line without having too many new components lying around already installed on-site so as avoid problems with compatibility issues during installation time frames. The PCIe slots are connectivity ports added to the motherboard which allow you to connect various peripheral devices to your systems, such as graphics cards, video cards, audio cards, and more. The more PCIe slots you have, the more connectivity option you will have. So make sure to opt for the motherboard that offers the connectivity of other hardware that you require.
The BIOS is the pre-built software on the motherboard that is responsible for detecting the components connected to the motherboard and also forming a connection between various components. Motherboards come with BIOS, which need to be upgraded from time to time. Make sure that your BIOS is compatible with your processor; otherwise, the motherboard won’t be able to recognize it. Look out which motherboard offers the best BIOS set and BIOS recovery option.
Comparison of Ryzen 9 3900X vs 3700X vs 3600X
Whichever Ryzen 3000 processor you choose to buy, you’re going to have a capable PC ready for action.

AMD of this processor is one of the most capable desktop processors the manufacturers, at present, we have the latest technology of Ryzen 9 and Threadripper. But 3700X still offers excellent value and is worth your money with six cores and a TDP of lower than the latest Ryzen 9 3900X if you don’t need all that performance.
The Ryzen 5 3600X is a little more down to Earth than the older model and is vastly more affordable, making it quite the processor for most gaming rigs and workstations. When you don’t need a mass of cores and threads, this CPU will be more than relaxed to play your favorite games and render all your media. While comparing to 3900X, both processors work well with RAM that’s clocked at 3200MHz, support AM4 chipsets, are built on the 7nm Zen 2 architecture, and even work with PCIe 4.0 hardware. At just 95W and 105W for the two Ryzen CPUs, you’ll also be able to avail an efficient cooler out of the box, which is essential in running the PC under a heavy workload.
How We Chose The Best Ryzen 9 3900x Motherboard
If you want the absolute best motherboard for ryzen 9 3900x, then there are several factors you should closely consider. Remember – determining our requirements while buying a motherboard, and going about the buying process accordingly is our ultimate goal. Though the list goes on and on, these are the most vital aspects to evaluate when purchasing the motherboard for Ryzen 9 3900x.
Choosing a relevant chipset is the first fundamental part of buying a motherboard for your 3900x. AMD Ryzen processors are highly credited for their flexible compatibility, which is one of their primary selling points. The AMD X570 chipset is currently the top-of-the-line chipset you can get for your 3900x, with all the flagship features. The AMD B550 is another relatively cheaper option. If you are looking for something a bit more wallet-friendly, then even a B450/X470 motherboard is a decent choice for the 3900x. However, due to the lack of PCIe 4.0 lanes, we do not recommend the older 400 series motherboards.
Once you have made up your mind on a particular chipset, the next step is to decide which form factor to opt for. There are three main form factors to choose from: ATX, micro-ATX, mini-ITX. Naturally, smaller boards are less feature-packed than their full-sized ATX counterparts. Thus, it all depends on what you want – whether it’s the compactness you’re looking for, or a better feature set without having to make any considerable compromises.
Voltage Regulator Module (VRM)
It is essential to have sufficient, high-quality VRMs in your Ryzen 9 3900x motherboard especially when pairing it with a power-hungry processor. Cheap quality VRMs tend to degrade quickly, specifically when under persistent heavy loads. This ultimately has negative effects on your CPU’s performance. So, investing in a high-end CPU and cheaping out on a motherboard will cost you in the future. It is always wise to invest in a quality motherboard as the VRMs are much more stable and long-lasting.
Upgrade Path From X570 and B550
Spending money on a motherboard for Ryzen 9 3900x time and again while frequently swapping it out is a hassle. Hence, it is beneficial to have prior knowledge about a motherboard’s CPU support. For example, the Ryzen 5000 series is likely to be the last batch of Ryzen processors officially compatible with 400 series motherboards (B450/X470). On the other hand, the B550 and X570 motherboards will have support for the next-gen processors. Therefore, it is better to loosen your pocket a bit and go for a newer motherboard. It will allow you to replace your older Ryzen 9 3900x processor with a later-gen processor, without having the need to change your motherboard as a whole.

Frequently Asked Questions
The Ryzen 9 3900x is an excellent CPU for gaming on a high level. Its staggering 12 cores and 24 threads provide enough computing power to run the most popular AAA titles at high FPS. Some of the earlier Ryzen CPUs were considered to have relatively poorer single-core performance as compared to their Intel equivalents. However, AMD has certainly improved their game with the 3900x, as we get to see better benchmarks and outstanding performance on a wide range of tests. Obviously, we would recommend pairing it with a good GPU – an RTX 2000 or the newer 3000 series card for gaming at those higher resolutions.
The answer to this is a big yes. Being a third-generation CPU, the Ryzen 9 3900x falls in a moderate and very reasonable price spectrum. We have already talked about its incredible per-core performance, which makes it an excellent value-for-money product overall. Not only this, the stock coolers that come with Ryzen chipsets are much better than Intel’s stock coolers too. As a result, they provide more overclocking headroom without having to make any additional investment.
The 105W TDP Ryzen 9 3900x is, without a doubt, a power-hungry CPU that requires an efficient cooling system. The stock AMD cooler does a decent job at keeping temperatures low while also providing a bit of overclocking headroom. If you are going to run the CPU mainly on stock settings, then the stock cooler will be sufficient enough for the task. If you are a frequent overclocker, then it is wise to invest in a cooler from a renowned brand. With a high-end cooler (preferably an AIO), you can overclock your CPU to newer heights without having to worry about soaring temperatures or overheating issues.
