Acpi Genuineintel---intel64-family-6-model-58 May 2026
The string "ACPI GenuineIntel-Intel64 Family 6 Model 58" 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).
Instruction Sets: x86-64, MMX, SSE4.2, AVX, AES-NI, and F16C. Representative Processors
This model family includes some of the most popular CPUs from the early 2010s:
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. acpi genuineintel---intel64-family-6-model-58
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. The string "ACPI GenuineIntel-Intel64 Family 6 Model 58"
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:
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? Or a custom identifier the kernel uses for quirk handling
Is the system having trouble waking from sleep or managing power?
This is a detailed technical deep dive into the ACPI identifiers GenuineIntel, intel64, family 6, and model 58 (0x3A). This combination points to a specific, well-known Intel CPU microarchitecture.
4. Example of where this appears in Linux
In /proc/cpuinfo or dmesg you might see:
ACPI: SSDT 0x... 0009a (v1 GenIntel CpuPm 00003000 INTL 20091013)
Or a custom identifier the kernel uses for quirk handling.

3. Why might this appear in a paper or analysis?
You mentioned "paper" – if you’re looking at a research paper, this string likely came from:
- Power management or ACPI experimentation – the paper might be analyzing CPU idle states (C-states), P-states, or thermal behavior on Ivy Bridge.
- Kernel boot logs – researchers sometimes include anonymized or raw log snippets.
- Hardware fingerprinting – using ACPI/CPUID for deterministic identification.
If you share more context from the paper (title, sentence, or figure caption), I can give a more precise explanation of why that string was relevant to the study.
1. Decoding the String
To understand the string, we must break it down into its constituent parts:
acpi: This indicates the source of the information. ACPI is a standard for how the OS communicates with hardware for power management and configuration.genuineintel: This is the vendor string returned by the CPU. It confirms the manufacturer is Intel.intel64: This indicates the processor supports the x86-64 instruction set (commonly known as 64-bit).family 6: This is the CPU Family. Intel uses "Family 6" for most of its Core, Xeon, and Pentium processors starting from the Pentium Pro era up to modern chips. It essentially designates the generation architecture.model 58: This is the specific identifier that narrows down the exact hardware generation.
Executive Summary
This string identifies a computer processor manufactured by Intel. Specifically, it refers to the 3rd Generation Intel Core "Ivy Bridge" processor family. These CPUs were released in 2012 and were the first to use Intel’s 22nm manufacturing process.
Part 1: Breaking Down the String
Let’s dissect the keyword into its semantic tokens:
- ACPI: The firmware interface standard for OS-directed power management and device configuration.
- genuineintel: The CPU vendor identification string returned by the CPUID instruction (Intel’s 12-character string: "GenuineIntel").
- intel64: Indicates the CPU architecture (Intel 64-bit), formally known as x86-64 or AMD64.
- family-6: The processor family number. In Intel’s taxonomy, Family 6 encompasses all modern Core architectures (from Pentium Pro to Alder Lake).
- model-58: The specific model number within Family 6.
In Linux kernel source code (specifically in arch/x86/kernel/cpu/intel.c and drivers/acpi/processor_driver.c), this string is generated when the ACPI processor driver matches a detected CPU against its internal tables. It is not an error; it is a debug or identification token used to apply model-specific quirks and power management policies.
