Things to Consider When Buying a Motherboard That Supports PCIe 4.0
Socket and Chipset Compatibility
The motherboard you consider must be compatible with your processor. Otherwise, what’s the use?
Every motherboard has a particular socket, whereas every processor has a particular chipset. When deciding on a motherboard, be sure its socket is compatible with the chipset of your processor. Otherwise, you cannot install your CPU on the motherboard.
The shape and size of a motherboard are identified by its form factor. Motherboards come in multiple form factors, but the common ones include ATX, Micro-ATX, and Mini-ITX. Most motherboards come in the ATX form factor, the largest of all.
When deciding on a motherboard, see if its form factor matches your PC case. Most PC cases support ATX and Micro-ATX form factors. But if you have a special PC case, it may only support a particular motherboard form factor. If that’s the case, go for a PCIe 4.0 motherboard with the right form factor.
Support for Overclocking
Overclocking your computer boosts its performance though it comes at the risk of temperature increase.
But some motherboards have locked multipliers that keep you from overclocking your CPU or GPU. So, if you want to overclock your computer, opt for a motherboard with overclocking capabilities.
Before overclocking your processor, manage proper cooling, as overclocking leads to excessive heat production, which could result in physical damage to your computer hardware.
With that at hand, consider a PCIe 4.0 motherboard with effective cooling, multiple fan headers, and good heatsinks to maintain its temperature when overclocking.
When deciding on a motherboard for your computer, ensure it has the required connectivity options so you can connect the important peripherals and devices.
The two main types of ports on motherboards are data transfer and display ports. Speaking of data transfer ports, USB Type-A and USB Type-C ports are the most important ones to look for.
Most motherboards include USB Type-A ports. But since USB Type-C ports are modern and more advanced, not many motherboards include it.
Regarding display ports, VGA, DisplayPort, HDMI, and Thunderbolt are some important ones to look for. But if you install a graphics card on your motherboard, you can get away with whatever display ports are available.
When choosing a PCIe 4.0 motherboard, you should see what type of storage types it supports.
Most motherboards support traditional SATA drives, but not all support the modern-day M.2 storage drives. These M.2 drives are faster, smaller, and more reliable, making them a preferable solution for most users.
So, when choosing a PCIe 4.0 motherboard, it’s recommendable to go for motherboards with M.2 slots.
BIOS is an important part of any motherboard. It stands for Basic Input/Output System and is a program that starts the hardware on the motherboard once you power on the computer. The Setup Utility in BIOS is simple to use, but you’ll need to check if it has customizable options.
There are several advantages to having a custom BIOS, but the main ones are that it may be used to fine-tune an existing solution. Also, a custom BIOS will change how the system boots up to improve security and make the system more manageable. Further, it will support expensive co-processing hardware to enhance system performance.
Most users nowadays prefer Bluetooth-enabled motherboards to wirelessly share data with their other devices, like smartphones. If you want to connect your computer to your peripherals, like a wireless keyboard, mic, speaker, or headset, go for a motherboard with Bluetooth support.
Note that most desktop motherboards have two versions – one with Bluetooth and one without it. The Bluetooth-enabled version costs more but is worthwhile.
Generally speaking, motherboards offer decent audio quality. It’s good enough for most users. So, you don’t need an expensive motherboard for good-quality audio.
Still, go for a newer motherboard to ensure it has the latest audio technology. This optimized sound technology will ensure you hear less static noise and distortion at high sound levels.
Also, audio processors and audio capacitors are close to the graphics card in newer motherboards to provide high-quality audio.
It’s likely you’ll be connecting your computer to one or more wireless or wired networks, such as the Internet. Your motherboard’s networking capabilities will determine how much flexibility you get when doing so. They will also impact its data transfer speed when networking.
So, when choosing a motherboard see if it has a high-speed Ethernet port to provide a fast-speed wired connection.
If you prefer wireless connections, opt for a motherboard with built-in WiFi. Further, it’s preferable to go for a motherboard with newer-generation WiFi for blazing-fast data transfer rates.
Memory (RAM) Limit
RAM plays a significant role in the performance of your computer. Your programs and games may lag or even crash if you don’t have enough RAM on your motherboard.
So, when choosing a motherboard, see how much RAM it supports. Most motherboards support up to 128GB, which is sufficient for most users and reliable in the long run.
Aesthetics are not an important thing to consider when choosing a PCIe 4.0 motherboard. But if you want to build a good-looking setup, it’s worth opting for an aesthetically pleasing motherboard.
When it comes to motherboard aesthetics, RGB lighting is the first thing that comes to mind. It gives your motherboard a fancy look and complements your overall setup. Motherboards with RGB lighting are particularly for gamers who want a gamer vibe from their gaming setup.
What is PCIe 4.0?
PCIe 4.0 is the newer-generation and fastest version of PCIe slots that connect graphics cards and other expansion cards with high data transfer speed. These cards include WiFi cards, Bluetooth cards, and SSDs.
PCIe 4.0 is backward compatible, so you can connect PCIe 4.0 expansion cards to PCIe 3.0 slots.
The table below contains information about the bandwidths of PCIe 4.0 slots.
PCIe 4.0 Bandwidths
|x1 slot||x2 slot||x4 slot||x8 slot||x16 slot|
|1.969 GB/s||3.938 GB/s||7.877 GB/s||15.754 GB/s||31.508 GB/s|
Why Go for a PCIe 4.0 Motherboard?
PCIe 4.0 motherboards offer faster data transfer speeds for PCIe-enabled devices like graphics cards and solid-state drives because compared to the previous PCIe slots i.e.: PCIe 3.0, a PCIe 4.0 slot can enable 16 GT/s per lane of data transfer, which is twice as fast as a PCIe 3.0.
As a result, the performance improves for tasks such as data transfer, gaming, and video editing.
Although x1, x2, x4, x8, and x16 lanes can be set in PCIe 3.0 and 4.0 slots, PCIe 4.0 slots have a better bandwidth throughput. A PCIe 4.0 motherboard also lets you upgrade to the latest expansion cards, including GPUs and NVMe SSDs.
Further, If you are creating a new system, then greater bandwidth will become increasingly crucial as the best gaming displays bring in a high refresh rate of 4K HD as the new standard.
People Also Asked
You should purchase a PCIe 4.0 motherboard if you wish to update to the new NVME SSDs and GPUs. There are more lanes and quicker speeds with PCIe 4.0. It’s because its bandwidth is double that of PCIe 3.0. This means PCIe 4.0 offers quicker data transfer, better gaming, and faster content creation than the older PCIe versions.
PCIe 4.0 is supported by most processors from AMD’s Ryzen 3000 and 5000 series, Ryzen Threadripper 3000 series, and Ryzen Threadripper Pro 3000 series. It’s also supported by Intel’s 11th-generation processors, also known as Rocket Lake processors.
A PCIe 4.0 is not essential for gaming since previous PCIe slots offer good enough bandwidth for smooth gaming. Additionally, not many graphics cards currently support PCIe 4.0. However, choosing a PCIe 4.0 motherboard can be good for future-proofing.
Since PCIe 5.0 is backward compatible, you can install a PCIe 4.0 graphics card on a PCIe 5.0 slot.
There are currently various PCIe 4.0 GPUs available. These particularly include graphics cards from AMD RX 5000 and 6000 series and the Nvidia RTX 3000 series.
But a PCIe 4.0 GPU is not essential as graphics cards are not fully utilizing even the PCIe Gen 3.0 bandwidth. Even the most advanced graphics cards have yet to approach the limit of PCIe Gen 3.0’s bandwidth.
PCIe 4.0 can be worth your money considering its amazing features. We hope our reviews for the 8 best PCIe 4.0 motherboards helped you determine which one to pick. If you want faster data transfer with better graphics power, get a PCIe 4.0 motherboard today!
