Let's break down the ID: . This is an ACPI-style Hardware ID (or _HID ). In practice, different OSes and logs may represent this in slightly different formats (e.g., ACPI\GenuineIntel_-_Intel64_Family_6_Model_58 ), but the core components are identical.
: Confirms the chip supports the 64-bit instructions necessary to address more than 4GB of RAM.
This is the specific identifier for the microarchitecture. In the context of Family 6, Model 58 (hexadecimal 3A) refers to the Ivy Bridge architecture. acpi genuineintel---intel64-family-6-model-58
Released in mid-2012, Ivy Bridge was a crucial milestone in Intel’s historical "Tick-Tock" development strategy. It represented a "Tick," meaning it took the existing microarchitecture of the previous generation (2nd Gen Sandy Bridge) and shrunk the manufacturing process node down from 32nm to 22nm. Key Architectural Highlights
: This indicates a mismatch between the OS and the motherboard's firmware. Because Ivy Bridge is an older architecture, modern operating systems (like Windows 11) may occasionally report ACPI "bugs" that are actually firmware inconsistencies. Let's break down the ID:
