Acpi Genuineintel---intel64-family-6-model-58 ((link)) Jun 2026

When an ACPI-compliant OS (like Linux, Windows, or BSD) parses the DSDT/SSDT tables, it reads the _HID (Hardware ID) or _CID (Compatible ID) for the CPU device. The string ACPI0007 is standard, but OEM firmware sometimes uses raw vendor strings.

The system firmware does not handle newer Windows 10/11 power management correctly.

If a BIOS update is unavailable because your motherboard is discontinued, you can stop Windows from putting the CPU into unstable low-power modes. Enter your . Navigate to Advanced CPU Settings or Overclocking . Look for Intel C-States (or C1E, C3, C6, C7). Change the setting from Enabled or Auto to Disabled . acpi genuineintel---intel64-family-6-model-58

To understand this identifier, let's break it down piece by piece:

Operating systems like Windows use a standardized naming convention to map out hardware properties via the Windows Management Instrumentation (WMI) and ACPI subsystems. When an ACPI-compliant OS (like Linux, Windows, or

: This is the most specific part of the identifier. The "Model" number, also from the CPUID instruction, differentiates between different microarchitectures and processor families within the broader Family 6. Model 58 (which is 0x3A in hexadecimal) is the code that positively identifies a processor as belonging to the "Ivy Bridge" microarchitecture.

: This is the broad architectural family that encompasses almost all modern Intel Core processors. : This is the specific decimal code (3Ah in hex) for the Ivy Bridge If a BIOS update is unavailable because your

Understanding this string requires breaking down the core principles of low-level hardware communication, unpacking what the numbers mean, and detailing how to resolve driver issues associated with this specific hardware ID. Anatomy of the Hardware ID

While it might look like a relic, this ID plays a small but crucial role in how an operating system interacts with your CPU.
