Acpi Genuineintel---intel64-family-6-model-58

By combining Model 58 with the Stepping (revision) number, we can identify specific processors. The vast majority of Model 58 CPUs have a Stepping of 9. They encompass a wide range of Intel's 2012-2013 lineup, including many desktop and laptop CPUs:

The cryptic string is a standardized hardware identification string used by Windows operating systems to communicate directly with a computer's central processing unit (CPU). If you encounter this string in the Windows Device Manager under an "Unknown Device" warning, or see it listed in system crash dumps (BSOD logs), your operating system is communicating with a 3rd Generation Intel Core processor—better known by its architectural codename, Ivy Bridge .

If you are researching this string, it is highly likely your PC is freezing, hanging on boot, or throwing a Blue Screen of Death (like WHEA_UNCORRECTABLE_ERROR or CLOCK_WATCHDOG_TIMEOUT ). acpi genuineintel---intel64-family-6-model-58

This guide breaks down exactly what this identifier means, what specific processors belong to it, how it utilizes ACPI tables, and how to address common system errors linked to this string. Decoding the Hardware Identifier

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. By combining Model 58 with the Stepping (revision)

Nevertheless, family 6 model 58 is in the wild. Millions of Ivy Bridge systems were sold from 2012–2014, and many still run Linux as home servers, media centers, or legacy workstations. If you encounter this string in the Windows

To understand the string, we must break it down into its constituent parts:

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

: If your system crashes, the error log often prints the processor ID to help developers know exactly which hardware was running at the time of the fault. Key Legacy Features
