The Stories
Confirms the chip is an authentic Intel product. Intel64: Denotes 64-bit architecture support.
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.
If you see this ID while trying to upgrade your operating system, you will hit a roadblock. Intel Family 6 Model 58 processors are .
Model 58 processors are over a decade old. Over time, silicon degrades. If you have an aggressive overclock or if the motherboard's voltage regulators (VRMs) are failing, the CPU will drop below its required voltage during power state transitions, causing an instant ACPI crash. 3. Chipset and Power Driver Mismatches
: Model 58 processors introduced native support for DirectX 11 , OpenGL 4.0, and OpenCL 1.2. This generation made casual gaming and 1080p video decoding highly viable without a dedicated GPU. acpi genuineintel---intel64-family-6-model-58
Understanding the ACPI GenuineIntel Intel64 Family 6 Model 58 Processor
The hardware identification string is a specialized low-level hardware identifier used by operating systems like Windows and Linux to communicate with Intel’s 3rd Generation Core architecture, codenamed Ivy Bridge .
Any computer displaying this string is powered by an Intel 3rd Generation Core, Pentium, or Celeron processor built on the 22-nanometer manufacturing process. These chips originally debuted in mid-2012. Desktop Chips : i7-3770K, i7-3770, i7-3770S Intel Core i5 : i5-3570K, i5-3570, i5-3470, i5-3330 Intel Core i3 : i3-3220, i3-3240 Mobile & Laptop Chips Intel Core i7 Mobile : i7-3610QM, i7-3520M Intel Core i5 Mobile : i5-3210M, i5-3320M ⚙️ Why Driver Issues Happen for "Model 58"
Visit the official support page for your motherboard manufacturer (ASUS, Gigabyte, MSI, ASRock, etc.). Download the latest available BIOS version. Confirms the chip is an authentic Intel product
While "Family 6 Model 58" sounds complex, it’s just technical shorthand for a 3rd Gen Intel "Ivy Bridge"
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
When Windows Device Manager or the msinfo32 tool prints this string, it is reading directly from the processor's internal registers via the instruction. Each fragment of the string contains vital technical data:
As Windows 10 and Windows 11 updated over the years, Microsoft changed how the operating system handles power management states (C-states). If your motherboard's BIOS is still running firmware from 2012 or 2013, it cannot properly translate the power instructions Windows is sending to the Ivy Bridge CPU. 2. Failing Hardware or Unstable Overclocks Introduced in the late 1990s, ACPI is an
: This confirms the chip features native 64-bit architecture support (Intel's x86-64 implementation, also known as EM64T).
Breaking down the identifier provides specific technical details about your CPU:
: This is the exact piece of data that narrows down the CPU's specific microarchitecture. In Intel's internal CPUID designation, Model 58 (0x3A in hexadecimal) represents consumer-grade Ivy Bridge chips built on the 22-nanometer (nm) process node. The Underlying Architecture: Intel Ivy Bridge (22nm)
