If you’ve decided to build a PC around one of the best processors on the market right now but you’re confused as to which motherboard to buy then you’ve come to the right place.
The 3900X is a 12 core 24 thread monstrosity that was developed by AMD and launched in 2019. It has a base clock of 3.8GHz and can be overclocked to reach frequencies up to 4.6 GHz. If you’re building a PC that will be able to handle any type of workload then this is the processor for you. Whether you’re a gamer, content creator, 3D animator, designer etc, this processor has you covered. Moreover, it’s quite future proof as it is compatible with the latest PCIe 4.0 tech and will be able to utilize the true potential of the latest GPUs without bottlenecking (see here for bottleneck calculators) them. However, for that to happen you will need the best motherboards for Ryzen 9 3900X.
Overclocking depends heavily on the motherboard. As a general rule, motherboards depends on VRMs to regulate the voltage so that power can be distributed throughout the system evenly which makes the system stable when it’s overclocked. The performance of GPUs is also affected by the motherboard as they depend on the PCIe lanes for transferring bandwidth. If you have a PCIe 3.0 x16 slot motherboard and you’re connecting the latest GPU on it then the GPU won’t perform as it should and you will be leaving performance off of the table. So before we dive into the list of the best motherboards that you can pair with a 3900X, let’s look into some factors which can affect your buying choice.
Quick Motherboard Recommendations for Ryzen 9 3900X
Factors to consider for the best motherboards for Ryzen 9 3900X
Your budget plays an important role in the type of motherboard you will get so set aside an amount that will let you buy the motherboard features that suits your needs.
VRMs and Power phases
VRMs are responsible for delivering the required voltages to the processor socket so that it continues to perform as it should. When overclocking, these VRMs play a key role as the processor requires a large amount of voltage that needs to be delivered in power phases. The more VRMs you have available on the board, the better it is for you as that would mean that the power distribution will occur evenly and even in high level overclocking the system will stay as stable as possible.
Expansion slots can play a vital role in your line of work as you will be able to get a variety of pc components hooked in on your motherboard which has more expansion slots as compared to a motherboard that doesn’t. You will be able to take advantage of SLI and crossfire tech as well as more M.2 drives on a motherboard with more expansion slots, so if your line of work demands that you work with more expansion slots then it’s no rocket science you need to get that motherboard. As a general rule if you’re building a gaming pc then you don’t need a lot of them, however, if you’re a content creator who needs to work with capture cards and other hardware that require expansion slots then you need more.
