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

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 hexadecimal or decimal designation explicitly isolates the Ivy Bridge 22-nanometer architecture (such as the popular Core i7-3770K or Core i5-3570K), which originally launched in 2012. Why Does This ID Cause System Crashes and BSODs?

: The enumerator. It tells Windows that this device entry was reported through the ACPI firmware tables rather than a physical hardware bus like PCIe or USB.

The string identifies a specific generation of Intel processors based on the Ivy Bridge microarchitecture. In technical terms, "Family 6" refers to the P6 family, and "Model 58" (0x3A in hex) specifically points to the 22nm Ivy Bridge desktop and mobile chips released around Q2 2012 . Core Specifications Architecture: Ivy Bridge (3rd Generation Intel Core). Fabrication Process: 22 nm with 3D Tri-Gate transistors. Common Sockets: LGA 1155 (Desktop). Memory Support: Primarily DDR3 (1333/1600 MHz). acpi genuineintel---intel64-family-6-model-58

Ivy Bridge has integrated PCIe root ports (on die), and ACPI handles ASPM (Active State Power Management) differently across microarchitectures. This is the specific "DNA" marker

: This stands for Advanced Configuration and Power Interface. It is the industry standard that allows Windows to control how much power goes to your CPU, handle sleep/hibernate modes, and monitor hardware temperatures.

If you are seeing this string in a system log, device manager, or driver utility, your system is likely running one of the following processors:

: Intel uses Family 6 to categorize almost all of its modern consumer and enterprise microprocessors built on the Core microarchitecture lineage. Why Does This ID Cause System Crashes and BSODs

While you can bypass the requirements, you will likely continue to experience ACPI errors, driver failures, and potential system instability because the underlying chipset drivers are no longer updated.

If a process related to this ID is taxing your system, it’s rarely the CPU itself. Instead, check for "System interrupts," which suggests a different piece of hardware is struggling to communicate with the Ivy Bridge processor via the ACPI. Performance in 2024 and Beyond

These were staple desktop and mobile (laptop) processors in the Windows 7 and Windows 8 era.
