How to Check PCI Express Version Compatibility on Any Motherboard

Through the following guide you will learn how to check the PCI Express version compatibility on any motherboard. Something very important if you want to choose the best motherboard for PC.

Check PCI Express compatibility on any motherboard

Each motherboard has its peculiarities, but all of them have similar technologies, including the all-important PCI Express. Next, we will show you which is the most recommended way to know the version of PCI Express that has a motherboard.

Go to the manufacturer’s website

Undoubtedly the best way to check which is the PCI Express version that a motherboard supports is by going to its official website. In other words, you will have to look for the model of the motherboard you want on the web and go to the page of the company that makes it.

Clearly this process varies in relation to the manufacturer, but usually each company uses a relatively similar system. Typically, these features are displayed directly on the summary of motherboard features.

In most cases, you should search for the term PCIe, a section where it will be expressed if the motherboard supports PCI Express 4.0, 3.0, 2.0 or 1.0 technology. Currently, the technologies that are often seen are PCI Express 4.0 and PCI Express 3.0.

Clearly PCI Express 4.0 presents certain improvements in relation to the previous versions. Although there are other aspects to consider if you want to know the best types of motherboards for laptops and computers, let’s take a look at the different types of PCI Express.

PCI Express 1.0a

PCI Express technology first saw the light of day in 2003, with version 1.0a. This allowed data transfers per lane of 250 MB / s and a total transfer of 32 Gbit / s in X16. Came to replace old AGP technology. In any case, by today’s standards it is quite an outdated technology.

PCI Express 2.0

PCI Express 2.0 saw the light in 2007, the transfers per lane increased to 500 MB / s and its total bandwidth is 64 Gbit / s in X16. Which represented an improvement in terms of graphics or video cards.

H4 PCI Express 3.0

This new technology sees the light in 2010 and represents a considerable improvement over PCI Express 2.0. In PCI Express 3.0, you can expect transfer rates of 984.6 MB / s per lane, while the total at X16 is 126 Gbit / s.

PCI Express 4.0

The current standard, PCI Express 4.0, represents a considerable improvement, doubling the total bandwidth present in PCI Express 3.0. In other words, you can expect transfers of 1969.2 MB / s per lane and a total of 252.1 Gbit / s in X16.

PCI Express 5.0

The new version of PCI Express, 5.0 seeks, like its predecessors, to double the bandwidths. The total speeds are then expected to be 3938.4 MB / s and have a total bandwidth of 504 Gbit / s in X16. However, such technology is not yet available to the general public.

Advantages PCI Express 4.0

Certainly in terms of games, the improvement of PCI Express 4.0 in relation to 3.0 is practically imperceptible. In any case, it can be useful for other purposes, indeed, not everything is to change the graphics card of your PC for a new one.

Where a considerable improvement is usually seen is in the NVMe storage units, where they can be expected higher speeds. Similarly, having this technology, greatly expanding the bandwidth, rarely makes you feel limited.

In any case, if you only plan to play games and use conventional SSDs, PCI Express 3.0 is certainly not bad at all. Even so, the most advisable thing if you plan to buy a new motherboard, is that this is PCI Express 4.0 compliant.
