Ryzen 9 3900x ( Amazon ) is a very decent processor, and the gaming community loves that. AMD’s Ryzen 9 3900X has 12 cores and a whopping 24 threads of processing power. This device has a base frequency of 3.8 GHz and can reach a maximum speed of 4.6 GHz. In terms of both gamers and programmers, this is the best option.
To run the most current graphics cards at their full potential, this processor supports PCIe 4.0. However, the best motherboard, Ryzen 9 3900x, is required to ensure that all connected hardware operates at maximum performance.
If you choose your motherboard carefully, it may assist your CPU in achieving its total capacity and maintaining it for a more extended period without being throttled. Overclocking performance is heavily influenced by a computer’s motherboard.
Better overclocking is possible with a smoother voltage supply with more VRM stages on a motherboard. The performance of your motherboard will also have a significant impact on the performance of your graphics card.
For the current generation of graphics cards, you may be limited by a motherboard with PCIe x16 slots version 3.0. The motherboard chipset is the primary source of high-quality audio for most PC users.
All of this necessitates that a consumer spends wisely on a motherboard. Some of the most outstanding motherboards have been evaluated by us for you, our readers. Let’s start with some pointers before you buy one:
Quick Shopping Tips:
Power Phases: Motherboards are equipped with power phases, which convert the voltage from the power supply unit to the voltages needed by the CPU during operation. The stress on these power phases increases dramatically during overclocking, and if the components are not built appropriately, this might result in component failure.
As a result of the increased number of power phases, the processor’s power burden will be more evenly spread over stages, resulting in more stable overclocking.
CPU Sockets: Sockets are an essential component of any motherboard that you should consider before buying. It would help if you chose the socket compatible with your Ryzen 9 3900x processor.
It is an AM4 socket-based CPU that has been the processor of choice for AMD for many years. AMD has a history of sticking with its socket size for an extended period, ensuring that future compatibility with AMD motherboards will not be a problem.
Expansion Slots: The number of expansion slots may be relevant to your needs. As a programmer, we suggest getting a larger motherboard, ideally, an ATX motherboard size, since it has a more significant number of expansion slots available.
Mini-ITX motherboards have only the bare minimum of expansion slots that you will require for your gaming computer setup. It is not advised for programmers to use this feature.
Aesthetics: Motherboards come in different colors and visual illustrations. All of these make it stand out inside your chassis. Instagram-worthy computers have RGB lightning, vicious PC cases, and enough fans to remove heat. We need to ensure that our motherboard has enough headers to support the accessories you will use to enhance your aesthetics.
