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

Let’s dissect the keyword into its semantic tokens:

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.

The OS uses ACPI to manage power, performance, and thermals. For this CPU, specific ACPI tables and objects matter:

If you have an Ivy Bridge system and notice cores stuck at 800 MHz, the issue is not this string, but rather ACPI thermal or power limit. Check:

Conclusion: The string acpi genuineintel---intel64-family-6-model-58 identifies your system as running on a 3rd Generation Intel Core processor (Ivy Bridge). If you are troubleshooting a driver error, you should look for "Intel Management Engine Interface" drivers or BIOS updates for your specific motherboard model.

The string "acpi genuineintel---intel64-family-6-model-58" refers to an Advanced Configuration and Power Interface (ACPI) hardware identifier for an Intel Ivy Bridge processor. Hardware Report: Intel Family 6 Model 58

This specific model corresponds to the 3rd Generation Intel Core (Ivy Bridge) architecture, manufactured using 22nm technology. Architecture: Ivy Bridge Microarchitecture: Intel64 Key Features:

Introduction of 22nm Tri-Gate transistor technology, which improved efficiency by nearly 20% over Sandy Bridge.

Support for AVX (Advanced Vector Extensions), SSE4.2, POPCNT, and AES-NI instruction sets.

Standardized thermal envelopes for desktop products (typically 35W to 77W TDP).

Integrated Graphics: Commonly paired with Intel HD Graphics 4000 or 2500. Common CPU Examples: Mobile: Core i5-3230M, Core i7-3630QM. Desktop: Core i7-3770K, Core i5-3570, Core i3-3220. Common Issues & Maintenance

If you are seeing this string in a system error or diagnostic log, it usually relates to power management or driver compatibility.

Some hypervisors (especially buggy KVM or QEMU defaults) pass an incomplete or manually mangled ACPI processor object. The triple-dash (---) is abnormal; it likely denotes a string concatenation artifact from printk formatting or a malformed DSDT. On real Ivy Bridge hardware, you should see a clean "ACPI: GenuineIntel (Family 6 Model 58)" without dashes. acpi genuineintel---intel64-family-6-model-58

The --- in the string suggests that three separate identifiers were joined: acpi + genuineintel + intel64-family-6-model-58. This could be from:

The string acpi genuineintel---intel64-family-6-model-58 is not a bug, not a warning, and certainly not a cause for alarm. It is a fingerprint – a piece of forensic evidence left by the Linux kernel to prove that the ACPI subsystem and the CPU driver have successfully identified and configured your Ivy Bridge server’s processor.

For the average user, ignore it. For the system tuner or kernel developer, it is a valuable breadcrumb. It reminds us that under every sleek user interface, a silent conversation happens between firmware and kernel – one that speaks in families, models, and ACPI states.

So the next time you run dmesg | grep genuineintel, smile. You are looking at the digital handshake that keeps your server running efficiently, core by core, C-state by C-state.

Understanding the Ivy Bridge Powerhouse: ACPI GenuineIntel Family 6 Model 58

If you have ever dug deep into your Windows Device Manager or system logs and found the string ACPI\GenuineIntel_-_Intel64_Family_6_Model_58

, you might feel like you’ve stumbled upon a secret government code. In reality, you are looking at the technical fingerprint of one of Intel’s most successful eras: the Ivy Bridge architecture. What Does the Code Actually Mean? This identifier is used by the ACPI (Advanced Configuration and Power Interface)

to tell your operating system exactly what kind of brain your computer has. Here is the breakdown: GenuineIntel : Confirms the processor was manufactured by Intel.

: 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

22nm microarchitecture, used in 3rd Generation Intel Core i3, i5, and i7 processors. Why Ivy Bridge Was a Game-Changer

Released in 2012, Model 58 represented a massive leap in efficiency. It was the first time Intel used 3D Tri-Gate transistors Let’s dissect the keyword into its semantic tokens:

, moving away from "flat" 2D transistors to a three-dimensional structure. This allowed for: Lower Power Consumption : Significant battery life improvements for laptops. Higher Performance

: Better processing power without the massive heat spikes of earlier generations. DirectX 11 Support : A major win for integrated graphics at the time. Troubleshooting the "Model 58" Driver Error

Often, users search for this string because they see a yellow exclamation mark in their Device Manager under "Other Devices." This usually means your system is missing the Intel Chipset Device Software If you see this error: Intel Support Page Download the Chipset INF Utility

Restart your machine. This helps the OS correctly identify the ACPI power management features of your Model 58 CPU. Is It Still Relevant Today?

While the technology is over a decade old, many Model 58 systems (like the legendary Core i7-3770K) are still in use as reliable office PCs, home servers, or budget gaming rigs. However, keep in mind that these CPUs are not officially supported by Windows 11

due to missing security features like TPM 2.0 and HVCI compatibility.
