How To Download and Install SMBus Controller Driver for Windows


Developed by Intel in the mid-1990s, SM Bus is an inexpensive communication device for motherboards. In short, it provides a two-wire interface between the system and power-related components for communications.

Also, SM Bus monitors voltage and temperature and can send a certain number of error messages when a problem occurs. This makes SM Bus an integral part of the system.

With that being said, you need to pay attention if you see a question mark or a yellow warning sign next to the SM Bus Controller in the Device Manager. This might be a sign of an outdated driver.

This post will discuss how to update SM Bus controllers for Windows 11, 10, 8, and 7.

What Is an SM Bus Controller?

SM Bus Controller, aka System Management Bus, is a low-level hardware device designed with integrated circuits or chipsets located on the Motherboard. It’s a two-wire interface that makes communication between the system and other power-related components effortless.

It is mainly responsible for measuring the temperature and voltage of the Motherboard. If you ever find a yellow question mark next to the SM Bus Controller (in Device Manager), your Operating System does not recognize the hardware. Hence, you need to troubleshoot the problem by updating its associated driver.

You don’t have to provide any information. The tool automatically lists outdated drivers and allows you to update the ones you want. To try it, click the button below to download it.
