What is an SM bus controller?

If you are shown that the SM-Bus controller is not installed or needs an update, the question arises as to what this is all about. We clarify it.

What do you need an SM-Bus controller for?

• SM-Bus stands for "System Management Bus". The chipset or the processor exchanges system data via this "channel".
• The SM-Bus controller thus helps to recognize the status of certain hardware and then to configure it.
• It can be used to display data such as manufacturer information, model and serial number, processor temperature, fan speed and various errors.
• It is usually not visible or configurable for the user. If the computer shows a warning about the SM-Bus controller in Device Manager, the latest driver for it should be installed. You can find this online from the manufacturer.
