The string identifies an Intel "Ivy Bridge" processor, typically belonging to the 3rd Generation Intel Core series (e.g., Core i5-3470 or i7-3770).
Examples: i7-3770, i5-3570, Xeon E3-12xx v2.
: This prefix indicates that the operating system discovered the hardware device using the ACPI tables embedded within the system’s motherboard BIOS/UEFI firmware.
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 acpi genuineintel---intel64-family-6-model-58
This comprehensive guide decodes this specific string, explains the underlying Ivy Bridge architecture, and walks you through troubleshooting common driver, power management, and Windows upgrade issues. Decoding the Hardware String: What Does It Mean?
To fix issues related to this identifier, it helps to decode exactly what the string means:
When Windows cannot catalog the ACPI sub-components of Model 58, it is missing the platform configuration file. The string identifies an Intel "Ivy Bridge" processor,
Error: "This device cannot start. (Code 10) — tv_ConfigMgrErr32" or "This device cannot find enough free resources that it can use. (Code 12)".
This indicates that the identifier is being reported by the system's firmware (BIOS/UEFI) to the Operating System kernel. It is the standard interface used for power management and hardware discovery.
: On Windows, ensure you have the latest Intel Chipset Device Software installed to help the OS correctly communicate with the Family 6 Model 58 architecture. 4.
