Acpi Genuineintel---intel64-family-6-model-140 [ SAFE ✪ ]

The ACPI DSDT (Differentiated System Description Table) lists the same core twice—once as a P-core and once as an E-core. Fix: This is a motherboard bug. As a workaround, add acpi=no_auto_ssdt in Linux or disable "Intel Speed Shift" in Windows Power Options.

Tiger Lake chips (Model 140) were the first to use Intel’s 10nm SuperFin

This is the crucial identifier. In Intel’s historical naming scheme, "Family 6" encompasses almost all post-Pentium Pro desktop, laptop, and server processors. Acpi Genuineintel---intel64-family-6-model-140

Users often encounter this string in the Windows Device Manager when a driver is missing or failing. Go to product viewer dialog for this item. Dell Latitude 5420 Laptop

This article decodes every segment of that identifier, explains why it appears in your system logs, and explores the unique challenges (and solutions) associated with the hardware it represents. Tiger Lake chips (Model 140) were the first

This is the vendor signature. While modern OSes rarely check for "GenuineIntel" versus "AuthenticAMD" for basic operations, legacy software and some cryptographic routines use this string to verify the CPU vendor and apply specific optimizations or workarounds. The triple-hyphen ( --- ) is a separator padding used to maintain a fixed-length string in legacy firmware tables.

This declares the instruction set architecture. It confirms the processor runs —Intel’s implementation of the x86-64 architecture. This is not to be confused with IA-64 (Itanium). It guarantees support for 64-bit memory addressing, general-purpose registers, and legacy 32-bit compatibility. Go to product viewer dialog for this item

Launched in late 2020, these chips marked a major leap for thin-and-light laptops by introducing the Willow Cove microarchitecture and Intel Iris Xe Architecture & Key Specifications

Rare, but seen when running very old 64-bit OSes (Windows XP x64 or early Vista). Model 140 supports these, but the ACPI string is malformed by a legacy bootloader. Fix: Enable UEFI native boot. Disable CSM (Compatibility Support Module) entirely.

: CPU frequency scaling stuck at low values. Cause : ACPI _PSS table might have invalid P-states for model 140. Fix : Boot with intel_pstate=passive or acpi_cpufreq as fallback.
