With the release of the next-gen Ryzen processors, AMD has unleashed a savage beast on its competition. Leading the line-up is the AMD Ryzen 9 3900x processor, having 12 cores, which makes it an absolute overkill for performance. But to make the most out of the raw performance of this processor, you need to pair it with a good motherboard; else, you will be crippling the beast.

The processor itself is pretty expensive; you can’t pair it with a cheap motherboard as it can toast the components under a high load. That is why in this thread, we will be talking about all the things that you should consider before buying a motherboard for your AMD Ryzen 9 3900x.

1. Form factor

The form factor refers to the size of the motherboard, and it is the first thing to consider. There are three different form factors, and the largest one among them is ATX. Check if your cabinet is capable of housing the motherboard. Meanwhile, the micro ATX is a compact one, and the micro-ATX is the smallest form factor. The bigger the motherboard form factor, the bigger the chances of expansion option.

2. Chipset

The chipset is responsible for deciding what GPU, RAM, or other attachment. So it is another significant factor to check.

3. Compatibility with the processor

Since processors have different versions or generations like 1st gen, 2nd gen, or 3rd gen, you must check whether the motherboard supports the particular generation. Though some motherboards can support all three generations, some motherboards don’t.

4. PCI-e and expansion slots

The “more is better” thing should be considered here. If you add more memory or need connectivity options, you need more expansion slots in your motherboard if you need to attach extra graphics cards, sound cards, or network cards.

5. M.2 slots

If you are looking to add SSD to improve your performance and storage, then it is crucial to check whether the motherboard has M.2 slot. That said, if the motherboard has one m.2 slots well and good, and if you can get dual m.2 slots, you can install multiple SSDs.

6. Ports

When buying a motherboard, be clear with the kind and number of connectivity options that you need because many times companies try to lure you with features that you may not need, so it is better to do your homework. Apart from the M.2 slots, it is necessary to check other ports you need for attaching a keyboard, mouse, or any other optical device. Apart from these ports, check for Wifi or Bluetooth adapter options and check for an ethernet port.

7. Heatsinks and quality of the motherboard components

As the processor is quite power-hungry with 105-watt TDP, it is bound to generate a lot of heat, and the generated heat needs to be circulated quickly, or else it can damage the components.

The other thing to consider is the quality of the components used in the motherboard; if you are going with a higher specification motherboard, generally, it will have good quality components. You can also check reviews and research, narrowing down your choice.


With every BIOS update, the chipset performance would improve. That said, most motherboards support BIOS updates, but it is recommended to confirm it once before buying.

9.Overclocking Ability

When buying a gaming processor, most people like pushing the processor to its limits by overclocking it. To overclock a processor, one needs the motherboard to be compatible with it. So, before buying a motherboard, check its overclocking ability and the kind of BIOS.

These are some things that you should consider before buying a motherboard for the Ryzen 9 3900x and making the most out of it. If paired with the right type of motherboard, this processor has the potential to ravage its competition and put them to shame


1. Does Motherboard Affect CPU Performance?

A motherboard doesn't directly affect a CPU's performance. But things like poor power supply, low-spec connectivity options, and no overclocking features can affect the performance of the CPU.

2. Is B550 recommended for Ryzen 9 3900X?

B550 is considered a powerful chipset as it uses CPU lanes for providing PCIe 4.0 to the expansion cards and M.2 storage drives. Compared to the other high-end chipset, this one takes higher power but has active chipset coolers that maintain the normal temperature while working. Also, it is well-balanced and is available at a mid-range price. 

3. Is the Ryzen 9 3900X overkill?

First, understand that the Ryzen 9 3900X is a 12core and 24 thread CPU, which is massive. So if you are doing any high-end works like video editing or video recording, or multi-threaded tasks, then this CPU is ideal. On the other hand, considering this CPU for lower-end works like regular gaming or simple works is overkill. 

4. How can I overclock my processor?

Mostly, the overclocking is done through computer software or BIOS. Look for a graphical user interface Bios, as it makes the overclocking process simpler.

5. Can I pair my processor with any motherboard?

No, you can only buy a motherboard that is compatible with the socket type that your processor has, else you will end up ruining your processor.

6. Do I need an aftermarket heatsink for the processor?

If your end goal is to overclock your processor, then buying an aftermarket heatsink is a must, or else you will end up frying your chipset. Also, apply an ample amount of thermal paste on the chip before installing the CPU heatsink.


When it comes to productivity work such as editing, documentation media encoding, rendering, or photoshop, Ryzen 9 3900x is an impeccable choice of processor that offers you the best technology to carry out these works with utmost accuracy. To increase the potential of this exemplary processor, you need to pair it with an unsurpassed motherboard to increase its efficiency to exceptional levels.

The above list consists of the best motherboard for Ryzen 9 3900X. Usually, the X570 consists of all the latest features available in the industry, like PCIe Gen 4.0, giving speeds up to 64 GB/s and at least a dual M.2 slot, of which one is based on Gen4 x4 PCIe standard excellent construction quality with Japanese capacitors, plenty of USB 3.0 and USB type C.

The B450 and B550 are relatively budget-oriented yet packed with features like PCIe Gen4 x16 slot, Wifi 6 enough fan headers for cooling, and storage solutions. I hope you grabbed the ideal mobo for your CPU cabinet.
