Officially, these processors are not supported by Windows 11. While it can be installed via "dirty upgrades," users often report performance issues or a lack of security feature optimization.
This is the specific "DNA" marker. In Intel’s world, Family 6 covers almost all modern microarchitectures, but (or 3A in hexadecimal) specifically identifies Ivy Bridge chips built on the 22nm process. Historical Significance
This is the precise technical "signature" for Intel’s 3rd Generation Core architecture, better known as Ivy Bridge . Why This Identifier Appears
is a hardware identification string used by Windows operating systems to catalog and manage specific central processing units (CPUs). It identifies processors based on Intel’s Ivy Bridge microarchitecture (specifically, CPUID Family 6, Model 3A in hexadecimal, which converts to Model 58 in decimal). Released in 2012, this generation of processors introduced Intel's 22-nanometer (nm) manufacturing process and pioneering 3D Tri-Gate transistor technology. acpi genuineintel---intel64-family-6-model-58
Are you seeing this ID because of a or are you trying to verify Windows 11 compatibility ?
Under normal operating conditions, you will never see this string unless you intentionally look for it in the Windows Registry under HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\ACPI .
If you are digging through Windows Device Manager, checking system logs, or diagnosing a Blue Screen of Death (BSOD), you might encounter the identifier . Officially, these processors are not supported by Windows 11
Understanding "ACPI\GenuineIntel___Intel64_Family_6_Model_58"
The string is a specific Windows hardware device ID that points directly to Intel Ivy Bridge (3rd generation Core) processors .
Marking notes for graders
Linux kernel has excellent support:
ACPI needs to know the precise CPU model for several reasons:
This is the most critical fix for ACPI-related processor errors. Reboot your PC and tap or Delete to enter your BIOS. Note your current BIOS version and motherboard model. In Intel’s world, Family 6 covers almost all
