x86-64, MMX, SSE4.2, AVX, AES-NI, and F16C. Representative Processors
is a hardware identification string used by Windows operating systems to catalog and manage specific central processing units (CPUs). It identifies processors based on Intel’s Ivy Bridge microarchitecture (specifically, CPUID Family 6, Model 3A in hexadecimal, which converts to Model 58 in decimal). Released in 2012, this generation of processors introduced Intel's 22-nanometer (nm) manufacturing process and pioneering 3D Tri-Gate transistor technology.
To understand this specific string, we first need to understand ACPI. Introduced in the late 1990s, ACPI is an open standard that allows an operating system to communicate with and manage the power usage of its hardware. Before ACPI, power management was largely the BIOS's responsibility. ACPI shifted that control to the OS, enabling features like putting individual devices to sleep when not in use or waking the system on a timer.
It may result from:
: Denotes that the device is bound to the Advanced Configuration and Power Interface table within the motherboard BIOS/UEFI. This controls sleep states (C-states) and clock modifications.
If you see "ACPI" errors related to Model 58 in your Event Viewer, it often points to a conflict between the Windows Power Plan and the BIOS settings. Updating your is the standard fix for these communication errors. 3. High CPU Usage
: Confirms the chip supports the 64-bit instructions necessary to address more than 4GB of RAM. acpi genuineintel---intel64-family-6-model-58
In Intel's organizational taxonomy, encompasses nearly all desktop, mobile, and server microprocessors derived from the foundational Intel P6 design. This line extends from the late-1990s Pentium Pro through Nehalem, Sandy Bridge, Ivy Bridge, and modern Core processors. 4. Model 58 (Hexadecimal: 0x3A)
: Windows uses these identifiers to fetch the correct drivers or microcode updates.
If you need to or patch DSDT for this exact CPU, let me know and I can provide specific ASL code or kernel module snippets. x86-64, MMX, SSE4
: This is the most specific part of the identifier. The "Model" number, also from the CPUID instruction, differentiates between different microarchitectures and processor families within the broader Family 6. Model 58 (which is 0x3A in hexadecimal) is the code that positively identifies a processor as belonging to the "Ivy Bridge" microarchitecture.
user wants a long article about the keyword "acpi genuineintel---intel64-family-6-model-58". This looks like a specific hardware identifier string from Linux ACPI tables. I need to cover what this string means, its technical details, the processor it identifies (Intel Core i7-3xxx? Let me confirm), its architecture (Ivy Bridge?), and provide context for system administrators, Linux users, and tech enthusiasts. I should also include troubleshooting advice. To do this, I need to gather information from various sources. I'll start with a set of searches to cover the different aspects. search results provide various pieces of information. To get a comprehensive understanding, I need to open several relevant pages. These include the lscpu results, the Geekbench result showing the processor codename, the Microsoft Q&A thread about device migration, the Linux kernel bug report, the Intel microcode page, and the Wikipedia page for Ivy Bridge. I'll also look at the openbenchmarking results, the Tk Source Code page, the Numerade page, and the TechPowerUp article. search results provide a good foundation. I'll also search for more specific technical details about ACPI.'ll also search for "ACPI Processor" and "GenuineIntel" to get more context. have gathered information from various sources. Now I need to structure the article. The article will include an introduction, decoding the string, technical deep dive, common places to find the identifier, why it matters for troubleshooting, and the legacy of Ivy Bridge. I will cite the relevant sources. string acpi genuineintel---intel64-family-6-model-58 might look like an error, but it is in fact a precise, systematic identifier used by your computer's firmware. For system administrators, Linux enthusiasts, and anyone troubleshooting hardware, this string is a key that unlocks a wealth of technical information about your CPU. This article will decode the string, explore the processor technology it represents, and explain why you might encounter it in your operating system.
Intel64 is Intel’s implementation of the x86-64 architecture (AMD64 originally, but fully compatible). It confirms that the CPU runs in (IA-32e mode in Intel terms). On Linux, this typically means the kernel was compiled with CONFIG_X86_64 , and the ACPI subsystem is dealing with a 64-bit capable processor. Released in 2012, this generation of processors introduced
