For years I used a MSI FM2-A55M-E33 in my work computer at my home office. From the first time I started the machine and installed drivers from MSI’s website I was always missing the “SM Bus Controller” driver. Everything seemed to work fine so I just ignored it for the few years I used that motherboard.
However, I recently upgraded my work computer to a different motherboard and put the old MSI FM2-A55M-E33 into my media server. The media server still runs Windows 7, but again the SM Bus Controller driver was missing just as when I ran Windows 10 on the motherboard. Generally, I only get drivers for devices from the device manufacturer’s website but I decided to google this missing SM Bus Controller driver issue and see what I could find.
So what’s the solution to a missing SM Bus Controller driver on a MSI FM2-A55M-E33 motherboard? It turns out it’s technically just a Windows Driver to be used on all newer AMD chipsets that for some reason isn’t offered from the MSI website. Perhaps Windows Update used to install it, I’m not sure, but it’s called “Advanced Micro Devices, Inc driver update for AMD SMBus” and can be found for various Windows versions here:

Apparently missing “Bus Controller” drivers happen with Intel based chipsets as well, and the fix for that is an Intel install called “Intel INF Utility” that lets Windows Update find the correct driver:

John started JSnowCreations as a place to post random tech guides and product reviews. However, while shopping for his daughter’s first “big girl” bed in 2019 he learned about the hidden dangers of fiberglass in mattresses. Since then, John has made it his mission to expose as much hidden fiberglass in mattresses as possible. His ultimate goal is federal regulations that ban fiberglass from being used in mattresses, or at least a law that require it to be listed in the material tags.
