“Unsupported_Processor” BSOD has been fixed by MSI

MSI has concluded its investigation into reports from some users experiencing random BSODs on certain hardware configurations.

The company has officially identified the root cause behind Blue Screen of Death (BSOD) issues on Intel 700 and 600 series motherboards, pinpointing the issue to settings within Intel’s Hybrid Architecture. Notably, this problem is exclusive to 13th Gen Core i9 CPUs and specific versions of Windows, the company adds:

  • Windows 11 22H2 (OS Build 2221.2215) KB5029351
  • Windows 11 22H1 (OS Build 22000.2360) KB5029332
  • Windows 10 22H2 (OS Build 19045.3393) KB5029331

In response to this issue, MSI has promptly released a BIOS update aimed at rectifying the problem by updating the Intel CPU microcode (uCode). This solution is expected to address any BSODs related to “Unsupported Processor” messages encountered on select 600 and 700 series motherboards when paired with the aforementioned CPU models and Windows operating systems.

MSI has committed to making this crucial BIOS update available for all 700 and 600 series motherboards within the current week, with further updates scheduled for release by the end of September. While the specific BIOS version is not explicitly mentioned, users are advised to seek a September release with the accompanying description.
