How to connect two graphics cards for Crossfire?

Dual graphics card Crossfire is a technical means used to improve computer graphics performance, especially in games to obtain smoother graphics and higher frame rates. Crossfire technology was first proposed by AMD and later introduced by NVIDIA and called "SLI (Scalable Link Interface)". So, how to connect dual graphics cards in Crossfire?

Before connecting dual graphics cards to Crossfire, you first need to understand the two connection methods - hardware connection and software connection.

Hardware connection is achieved through the physical interface connecting the two graphics cards. There are currently two common hardware connection methods: bridged connection and bridgeless connection.

A bridge connection uses a connection bridge to connect two graphics cards. This connection method requires the use of a cable called an "SLI bridge" to connect the SLI interfaces of the two graphics cards. SLI bridges are usually provided by motherboard manufacturers. Different models of SLI bridges may have different interface types, so you need to choose an SLI bridge that suits your computer configuration. When connecting, plug one end of the SLI bridge into the SLI interface of the first graphics card, and then plug the other end into the SLI interface of the second graphics card to ensure a stable connection.

The bridgeless connection connects two graphics cards through the PCI-E x16 slot on the motherboard, without the need for additional SLI bridge cables. First, make sure your motherboard supports bridgeless connections. Then, insert the two graphics cards into the two PCI-E x16 slots on the motherboard in turn, make sure they are firmly inserted, and then enable the CrossFire function through the motherboard BIOS settings.

The next step is the software connection. Whether it is a bridged connection or a non-bridged connection, you need to enable the dual graphics card crossfire function through software. Taking the NVIDIA graphics card as an example, the specific steps are as follows:

The first step is to download and install the latest graphics card driver. You can find the latest driver suitable for your graphics card model from the NVIDIA official website and follow the driver installation wizard to complete the installation.

The second step is to open the "NVIDIA Control Panel". In the Windows system tray, find the NVIDIA Control Panel icon, right-click and select "Open NVIDIA Control Panel".

The third step is to select the "Configure SLI, Multi-GPU Rendering Mode" option in "3D Settings". In the pop-up window, select "Maximize 3D Performance" or "Performance Mode". If you just want to use Crossfire technology for better gaming performance, select "Maximize 3D Performance".

The fourth step, click the "Apply Changes" button and then restart the computer. In this way, the dual graphics card crossfire connection is completed.

It should be noted that dual graphics card crossfire connection is not a function supported by all graphics cards, so before making the connection, you need to confirm whether your graphics card model supports the crossfire function. Also, make sure your power supply can meet the energy needs of both graphics cards to avoid computer crashes or graphics card damage due to insufficient power.

To sum up, dual graphics card crossfire connection can be achieved through hardware connection and software connection. Before connecting, you need to choose the appropriate hardware connection method and ensure that the graphics card model and motherboard support the CrossFire function. After the connection is completed, enable the CrossFire function through the software to enjoy more powerful computer graphics performance. I hope this article helps you understand the dual graphics card Crossfire connection.
