The identifier ACPI GenuineIntel Family 6 Model 58 refers to the Intel Ivy Bridge microprocessor architecture
, which was the 3rd generation of Intel Core processors (e.g., Core i3/i5/i7-3xxx). Key Features of Family 6 Model 58 (Ivy Bridge) 22nm Manufacturing Process : This was Intel’s first architecture to use 3D "Tri-Gate" transistors
, significantly improving power efficiency and performance over the previous 32nm Sandy Bridge models. PCI Express 3.0 Support
: Ivy Bridge introduced native support for PCIe 3.0, doubling the bandwidth for discrete graphics cards and high-speed storage compared to PCIe 2.0. Intel HD Graphics 4000/2500 : Featured a much-improved integrated GPU with support for DirectX 11 , OpenGL 4.0, and OpenCL 1.2. DDR3L Support
: Added support for low-voltage DDR3 memory, which helped extend battery life in laptops. Instruction Set Extensions : Includes support for AVX (Advanced Vector Extensions)
, Intel Turbo Boost 2.0, and Hyper-Threading (on supported models). Hardware Random Number Generator : Introduced the
instruction (Intel Secure Key) for high-quality, hardware-based cryptography. Identification Context In ACPI and Windows Device Manager strings:
: Refers to the Intel P6 microarchitecture lineage (which covers almost all modern Intel Core CPUs). Model 58 (0x3A) : Specifically maps to the Ivy Bridge desktop and mobile processors released around 2012–2013. (e.g., i5-3470) or check for driver compatibility
The identifier GenuineIntel Family 6 Model 58 refers specifically to the Intel Ivy Bridge microarchitecture (3rd Generation Core). If you are seeing this in a system log followed by an ACPI (Advanced Configuration and Power Interface) error, it typically indicates a communication mismatch between the CPU's power/thermal management and the motherboard firmware. 1. Hardware Identification
Knowing your specific processor model helps find the exact firmware updates needed. Architecture: 22nm Ivy Bridge (Tick-tock model "Tick"). acpi genuineintel---intel64-family-6-model-58
Common CPUs: Core i7-3770, i5-3570K, i5-3230M, and i3-3120M.
Integrated Graphics: Usually paired with Intel HD Graphics 4000 or 2500.
Check Yours: Press Windows Key + R, type msinfo32, and look at the "Processor" field. 2. Troubleshooting ACPI & System Errors
ACPI errors on this specific architecture often relate to power states (C-states) or outdated BIOS.

If your system reports family 6 model 58, here is what you actually own:
| Feature | Detail | |---------|--------| | Microarchitecture | Ivy Bridge | | Process technology | 22 nm (Intel’s first Tri-Gate “FinFET” transistor) | | Supported sockets | LGA1155, Socket G2 (rPGA988B), BGA1023 | | Supported chipsets | Z77, H77, Q77, Z75, B75, HM77, UM77 etc. | | Memory support | DDR3-1333/1600, dual-channel (max 32GB desktop, 16GB mobile) | | Integrated GPU | Intel HD Graphics 2500/4000 (DirectX 11, OpenGL 4.0) | | Instruction set additions | AES-NI, RDRAND, MOVBE, AVX (not AVX2), F16C | | TDP range | 17W (ULV) to 77W (desktop quad-core) | The identifier ACPI GenuineIntel Family 6 Model 58
Notable processors with model 58:
As of 2024, Family 6 Model 58 (Ivy Bridge) is considered legacy hardware.
_TMP (Temperature) – Returns thermal zone temperature. Ivy Bridge has DTS (Digital Thermal Sensor) per core, accessible via MSR 0x1A2._PSV (Passive cooling trip point) – OS reduces P-states when crossing threshold (e.g., 90°C)._CRT (Critical trip point) – OS initiates shutdown (e.g., 105°C)._ACx (Active cooling) – For fan control, though often handled by EC.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.
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.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.
