The string "ACPI GenuineIntel Family 6 Model 58" looks like a cryptic line of code, but it is actually the digital "birth certificate" for a specific generation of Intel processors. This identifier points to the Ivy Bridge

architecture, specifically the 3rd Generation Intel Core processors (like the popular i5-3570K or i7-3770K) released around 2012. Here is a breakdown of what this technical label tells us about a computer's "brain" and how it communicates with the rest of the system. The Breakdown of the Label

To understand this essay's subject, we have to decode the nomenclature:

This stands for Advanced Configuration and Power Interface. It is the bridge between the hardware and the operating system, allowing your software to tell the hardware when to sleep, wake up, or throttle power to save battery. GenuineIntel / Intel64:

This confirms the manufacturer and the 64-bit instruction set, which allows the computer to use more than 4GB of RAM—a standard for modern computing. Family 6, Model 58:

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

When Model 58 hit the market, it represented a "Tick+" in Intel’s famous "Tick-Tock" development cycle. It was the first time the world saw 3D Tri-Gate transistors

. Instead of being flat, transistors were built upward, allowing more of them to fit into a smaller space. This made computers faster and significantly more energy-efficient than the "Sandy Bridge" models that came before. Why It Still Matters

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.

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?

CPU Profile Report: Intel64 Family 6 Model 58 The identifier Intel64 Family 6 Model 58 refers specifically to the Ivy Bridge microarchitecture, which represents Intel's 3rd Generation Core processor family. This generation, launched around 2012, was the first to use Intel’s 22nm manufacturing process and "3D" Tri-Gate transistors. 1. Processor Identification

Family 6: This is the broad category for almost all modern Intel microarchitectures (P6 through the current Core series).

Model 58 (0x3A): Specifically identifies Ivy Bridge (Client) processors. Common examples include: Desktop: Core i7-3770, i5-3570, i3-3220. Mobile: Core i7-3610QM, i5-3210M. GenuineIntel: Indicates the vendor is Intel Corporation. 2. Understanding ACPI Context

When you see this string in a "useful report" or system log (like dmesg in Linux or msinfo32 in Windows), it is often related to Advanced Configuration and Power Interface (ACPI). ACPI is the bridge between your hardware and the operating system that manages power states (sleep, hibernate) and device discovery. 3. Common Issues & Solutions

If you are seeing this identifier in an error log or a Blue Screen of Death (BSOD), it typically points to one of the following:

ACPI BIOS Error: 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.

Action: Check your motherboard or laptop manufacturer's website for the latest BIOS/UEFI update. The identifier GenuineIntel Family 6 Model 58 refers

Power Management Conflicts: Errors may occur when the OS tries to put the CPU into a power-saving state (C-states) that the BIOS does not handle correctly.

Action: Try resetting BIOS to "Default Settings" or disabling "Fast Boot" in Windows.

Driver Compatibility: On Windows, ensure you have the latest Intel Chipset Device Software installed to help the OS correctly communicate with the Family 6 Model 58 architecture. 4. Technical Specifications Summary Microarchitecture Ivy Bridge (3rd Gen Core) Instruction Set x86-64 (Intel 64) Lithography Socket Types LGA 1155 (Desktop), rPGA988B (Mobile) Key Technologies AVX 1.0, PCI Express 3.0 (on most models), USB 3.0 support

Are you seeing this identifier because of a specific error message or system crash, and if so, what is the exact text of that error? Decoding Intel processor models reported by Windows

The text ACPI\GenuineIntel_-_Intel64_Family_6_Model_58 is a hardware ID used by Windows and other operating systems to identify a specific processor for driver management and power configuration. Technical Breakdown

ACPI: Standing for Advanced Configuration and Power Interface, this prefix indicates the operating system is communicating with the processor through the system's BIOS/UEFI ACPI tables for power management (like sleep states and frequency scaling). GenuineIntel: Confirms the manufacturer is Intel.

Intel64 Family 6: Refers to the microarchitecture family. Nearly all modern Intel processors since the Pentium Pro fall under "Family 6".

Model 58: This specific code identifies the processor generation. Model 58 (3Ah) corresponds to the Ivy Bridge architecture, typically found in 3rd Generation Intel Core processors (e.g., Core i5-3470 or i7-3770). Common Occurrences

You likely encountered this text in one of the following places:

Device Manager: Under the "Processors" section, looking at the "Hardware IDs" in the Details tab.

Event Viewer: In error logs or informational messages related to system boot or power transitions.

Linux Boot Logs: Often seen in dmesg or /proc/cpuinfo when the kernel initializes CPU cores. Troubleshooting

If you are seeing this in a "driver error" or "system hang" context:

Slow Boot/ACPI Errors: This can happen if the OS (especially Linux) has trouble parsing the motherboard's ACPI tables. Updating your BIOS/UEFI from the motherboard manufacturer's website is the primary fix.

Missing Drivers: Windows usually handles this automatically. If you see a yellow exclamation mark in Device Manager, install the Intel Chipset Device Software from the Intel Support site.

Are you currently experiencing performance issues or seeing this specific text in an error message? Solved: intel graphic update

This specific identifier, ACPI GenuineIntel Family 6 Model 58, refers to the Intel Ivy Bridge microarchitecture (3rd Generation Intel Core processors), specifically those released around 2012.

In the world of system diagnostics, seeing this string usually means you are looking at how the Operating System (OS) identifies the hardware via the Advanced Configuration and Power Interface (ACPI). What is "Family 6 Model 58"?

Intel categorizes its processors using a "Family," "Model," and "Stepping" system.

Family 6: This has been the standard for almost all Intel Core processors since the Pentium Pro.

Model 58 (0x3A): This specific hex code identifies the Ivy Bridge lineup. These were the first chips to use the 22nm manufacturing process and "3D" Tri-Gate transistors. Common Contexts

You likely encountered this technical string in one of the following places:

Device Manager/System Info: Windows uses these identifiers to fetch the correct drivers or microcode updates.

Linux Kernel Logs (dmesg): Linux identifies the CPU capabilities (like Turbo Boost or power states) using this model number during boot.

BSOD or Crash Logs: 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

If you are still running a "Model 58" machine, you are using a piece of hardware that introduced several modern standards: Part 3: Hardware Behind Model 58 – Intel

PCI Express 3.0: The first Intel chips to natively support the faster PCIe Gen 3. USB 3.0: Integrated support into the chipset (7-series). DirectX 11: Improved integrated graphics (Intel HD 4000). Troubleshooting Tip

If you are searching for this because of a system error or driver issue, you should look for "Intel 3rd Generation Core" or "7-series Chipset" drivers. Most modern operating systems (Windows 10/11 and recent Linux kernels) include these drivers by default, but a BIOS update from your motherboard manufacturer is often the best way to resolve ACPI-related "Model 58" errors. To help you further, could you tell me: Did you find this in a Crash Report or Blue Screen?

Are you trying to find drivers for an older laptop or desktop?
