A couple of weeks ago, a Windows 11 update began causing issues for MSI motherboard users, resulting in a BSOD ‘unsupported processor' error. After some investigation, the root cause of the issue has been found and a new BIOS update should fix things right up.

MSI and Intel have been working together to find a solution to this issue on MSI's Intel 700 and 600 series motherboards. It would seem that the unsupported processor error was primarily caused by a firmware setting of the Intel Hybrid Architecture and it mainly affected 13th Gen Core i9 processors running a couple of specific Windows 11 builds and one version of Windows 10.

MSI has begun rolling out BIOS updates for its motherboards to address the problem. In the list below, you can find the list of boards with an available link to the updated BIOS:

• MEG Z790 ACE – Link
• MPG Z790 CARBON WIFI – Link
• MPG Z790 EDGE WIFI – Link
