NVIDIA recently introduced its new SLI bridge, but it seems that many users aren’t able to get their graphics cards up and running. What’s going wrong? Why does the driver not recognize your card properly? Here are some of the most common fixes for this issue.
The “nvlink not detected” is a problem that has been present for a while. There are many ways to fix this issue, but the easiest way is to just update your drivers.
Creating the ideal computer setup — whether for graphics/editing, gaming, or something completely else – is mostly a matter of personal taste. Each individual has their own set of preferred specifications or features that are more important to them than others. However, it is a basic reality that each component must be compatible with the others.
An SLI bridge connects two graphics cards that are of the same kind. The bridge transmits data straight from one end to the other.
If your computer states the SLI bridge isn’t recognized, it might be because your power supply isn’t strong enough, your motherboard isn’t powerful enough, your video card or bridge isn’t correctly installed, or the bridge isn’t enabled for your motherboard. To repair, troubleshoot to find the source of the problem.
What is a SLI Bridge, and how does it work?
The Scalable Link Interface bridge is also known as the SLI bridge. SLI stands for Single Link Interconnect and is a tiny circuit board that comes packed with SLI-ready motherboards. This is a crucial difference to make since not every motherboard can support a SLI bridge.
At either end of the bridge are connections. They connect to the topmost connectors of SLI-ready video cards. Essentially, the board connects two video cards to boost performance and capacity. When the SLI setup is activated, the bridge connects two identical video cards to share information.
What Is the Purpose of a SLI Bridge?
So, why would you want to utilize a SLI bridge? SLI bridges allow data to be sent directly between two identical graphics cards, minimizing bandwidth limitations. If you have a single GPU that can satisfy your demands, a SLI bridge is usually unnecessary.
However, if you have a pair of x8 speed GPUs, bridging them may be beneficial. It is entirely dependent on your setup and requirements. The more components in the mix, the more likely one of them may fail, causing problems with the remainder of the arrangement.
The SLI Bridge Couldn’t Be Detected for a Few Reasons
There are a number of reasons why you can see a “bridge not detected” warning — the wording varies depending on the manufacturer. For example, the error message may instruct you to remove graphics cards that are incompatible with your SLI setup.
There might be a slew of reasons why your SLI bridge isn’t being recognized. Let’s go through the many concerns that might arise.
The Support for Legacy Motherboards Is Inadequate
One of the most important components in ensuring that your SLI bridge works is your motherboard. The motherboard serves as a central hub for all other components. If it is incompatible with one of the components, that component will not function properly.
If a correct jumper setting isn’t enabled on your old motherboard, it won’t be able to handle two graphics cards in SLI mode. Check with your motherboard’s manufacturer for instructions on how to correctly activate SLI mode and detect the jumper.
SLI Mode is turned off.
You can’t simply throw a bridge on top of your multiple graphics cards and expect it to function. Even if the SLI bridge is discovered, it will not function as it was intended. That’s why we need to start with the BIOS.
The word “SLI” may not be mentioned in your BIOS depending on your system. PCI or anything connected to PCI, such as PCI express, might be the culprit. To find out what BIOS settings your manufacturer uses, contact them.
You can go into the BIOS and activate SLI once you’re sure. This will enable the SLI bridge to be correctly recognized and begin transmitting data between the two graphics cards.
Some motherboards need the installation of a daughtercard. These are additional boards that are connected to the motherboard or a separate board. These are supposed to operate together to provide support for the two graphics cards.
Make sure you read the manufacturer’s instructions first. You may be able to get away without using a daughterboard depending on the type and manufacturer.
The Motherboard Doesn’t Have Enough Power
The motherboard’s – or at least one of them’s – job is to provide the required electricity to the different components it supports. If your SLI bridge isn’t being detected, it’s conceivable that the graphics cards aren’t getting enough power from the motherboard.
Most motherboards, for instance, feature a 4-pin power port near the SLI/PCI slot. This is the dedicated power source for those slots, ensuring that the power signal’s integrity is maintained. If your motherboard doesn’t have certain pins, it may not be able to accommodate the graphics cards’ power supply.
The SLI Connector is not correctly seated.
Any computer component must be correctly positioned in order to perform effectively. If your SLI bridge isn’t being identified, make sure it’s correctly positioned on the graphics cards. The SLI bridge will not be identified without that direct connection.
The easiest solution is to detach the bridge from the cards and then rejoin it. If you can’t locate the connection on your graphics cards, you may request one from the motherboard manufacturer. Additionally, depending on the graphics card you choose, you may not be able to utilize a SLI connection.
Insufficient power supply
It’s possible that the power supply you’re using isn’t capable of adequately powering each of the components, such as a twin graphics card arrangement. A 450-Watt power supply should enough for a simple SLI configuration.
The more complicated your system becomes, the more sophisticated setup you’ll need. You will want a more thorough power supply if you have high-end graphics cards. Before you buy a SLI bridge, look up the various power recommendations on the internet. A list of eligible motherboards should also be available. Keep in mind that you must be able to power these high-end graphics cards; they do not just slot into any motherboard.
What are the Advantages of SLI?
Knowing the numerous concerns that might cause your SLI bridge to fail to be identified, we need consider whether they are worth having in the first place. There are several apparent advantages to having two graphics cards, but it isn’t all flowers.
Graphics of higher quality
Improved picture quality without sacrificing graphical fidelity is one of the most significant advantages of utilizing twin graphics cards with a SLI bridge. When discussing the latter, it refers to everything that contributes to a visually pleasing gaming experience, such as frame rate, resolution, and detail.
Not only that, but having a SLI might be useful if you want to run a faster refresh rate than your monitor supports. It allows you to have playable frame rates while also improving the images’ overall quality.
The primary advantage of using a SLI bridge is that it provides higher overall performance. That is, if you are using a resolution higher than 1080p (4k or 8k). Aside from that, a SLI bridge won’t make much of a difference.
High-resolution displays, which offer a faster refresh rate, are popular for gaming. All of this implies that the GPU will have to work harder to produce those frames and pixels. Using a dual system linked via a bridge means not only being able to reach those maximal settings, but also doing it in a fluid manner.
To boost performance while playing games with high resolution settings (4k, 5k, 8k, and 16k), a SLI is required. Furthermore, having a higher refresh rate, such as 144Hz or above, necessitates having the necessary technologies to make the most of those higher specifications.
They seem to be cool.
Let’s face it, part of what makes gaming setups so fantastic is how aesthetically stunning they are. And, if you want to make your gaming system appear as nice as possible, you’ll need twin graphics cards with SLI.
There are clearly more compelling reasons to use a dual card system, but the enhanced look surely doesn’t hurt.
When it comes to SLI Bridge issues, the simplest explanation is often the correct one.
If you’re seeing a notice that your SLI isn’t being recognized, start with the basics. Often, the simplest answer is the correct one. The more complicated the answers get, the more likely there will be more issues.
To begin, make sure the bridge is correctly seated. This is the case most of the time. Whether that isn’t the issue, check to see if the bridge you’re using is compatible with your motherboard. With various manufacturers, you can’t simply plug and play.
After that, it’s possible that it’s time to upgrade motherboards. Some computers may not have enough power to enable multiple graphics cards in the first place. Consult the manufacturer if you’re unsure.

Frequently Asked Questions
Why cant I enable SLI?
A: Sony does not allow users to enable SLI on the PS4.
Why did SLI go away?
A: The main reason is because PhysX went to a different engine and it was no longer compatible with the older SLI drivers. This has led NVIDIA to develop their own GPU-based ray tracing technology called RT Cores, which combines both physics processing and rendering in one shader unit instead of two separate units like before.
How do I enable SLI bridge?
A: To enable SLI bridge, in the games settings menu make sure that your GPU is set to 1 and not 2, then press on the button which says switch. The next time you open up Beat Saber, it should be enabled!
