When your operating system reads this string during boot, it is interacting directly with the Advanced Configuration and Power Interface (ACPI) tables to query the Central Processing Unit (CPU) architecture. This particular identifier is famously tied to legendary consumer chips such as the desktop Intel Core i7-3770K and the mobile Intel Core i7-3540M .
In short, "Model 58" isn't just a number; it represents the transition to the 22-nanometer era and the foundation of the power-management features we take for granted in laptops today. of these specific chips or help you troubleshoot a driver issue related to this ACPI string?
In Windows, processors are identified by their CPUID. The "Family 6 Model 58" identifier points specifically to: Ivy Bridge (22nm). Release Date: Primarily 2012–2013.
Released in 2012, Ivy Bridge was a die shrink (from 32nm to 22nm) of the previous "Sandy Bridge" architecture, introducing Intel's then-revolutionary Tri-Gate (FinFET) 3D transistors. Popular desktop and mobile processors from this family include: acpi genuineintel---intel64-family-6-model-58
Click on the top menu bar, then click Scan for hardware changes . Windows will reload its built-in intelproc.sys microcode library to stabilize the device.

, significantly improving power efficiency and performance over the previous 32nm Sandy Bridge models. PCI Express 3.0 Support When your operating system reads this string during
: Refers to the microarchitecture family. Nearly all modern Intel processors since the Pentium Pro fall under "Family 6".
These were staple desktop and mobile (laptop) processors in the Windows 7 and Windows 8 era.
Expectations: correct IASL syntax, use of Processor declaration, _PSS and _CST packages, and comments. (10 marks) of these specific chips or help you troubleshoot
: The flagship desktop processor of this generation, highly favored by overclockers for its unlocked multiplier.
: This is the vendor ID string. When an Intel CPU powers on and executes the CPUID instruction, one of the first pieces of information it returns is the vendor string: "GenuineIntel". This tells the OS that the processor was manufactured by Intel Corporation. AMD processors, for comparison, return "AuthenticAMD". This string is taken directly from the CPU's own identification.
Even a decade later, you will still see this string in Windows Device Manager or Linux system logs. It serves as a reminder of a period where Moore’s Law was in full swing. These processors were so robust that many are still in use today for basic office work, home servers, or budget gaming builds.
: 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
You won't typically see this string on a retail box. It lives in the low-level software that connects your hardware to your operating system:
