CPU-Z 2.18

When you run CPU-Z, it scans your computer and displays key hardware details across organized tabs.

The CPU tab shows your processor's name, codename, manufacturing process, package type, core voltage, and specification.

You'll see real-time clock speeds, multiplier ratios, bus speed, and cache sizes for L1, L2, and L3 levels.

The Mainboard tab reveals your motherboard manufacturer, model number, chipset, and BIOS version - essential information when updating firmware or checking component compatibility.

The Memory tab displays your RAM type (DDR4, DDR5), total capacity, frequency, timings, and channel configuration.

The SPD sub-tab shows detailed specifications for each memory slot.

The Graphics tab provides basic GPU information including name, codename, and core clock.

For more comprehensive graphics card details, GPU-Z offers dedicated GPU monitoring with temperature sensors and VRAM specifications.

Why Should You Use It?

Know Your Hardware: Before buying new software or games, CPU-Z confirms whether your PC meets the system requirements. This prevents compatibility issues and wasted purchases.

Upgrade Wisely: Planning to add RAM or replace your processor? CPU-Z shows exactly what you currently have, so you can buy compatible parts. Check your motherboard chipset to verify which CPU generations it supports.

Troubleshooting: When your PC acts up, CPU-Z helps diagnose hardware issues. Abnormal voltages, incorrect RAM timings, or throttled clock speeds often point to specific problems.

Performance Monitoring: Overclockers and gamers use CPU-Z to verify their tweaks are working. The real-time clock speed display confirms whether your overclock holds under load.

Windows 11 Compatibility Check

One of the most common reasons users run CPU-Z today is checking whether their PC meets Windows 11's hardware requirements. Microsoft requires specific CPU generations, TPM 2.0, and Secure Boot for official installation.

After running CPU-Z, compare your processor against Microsoft's supported CPU list.

If you have a 7th generation Intel Core or older - or equivalent AMD processor - the official Windows 11 Installation Assistant will block your upgrade.

However, older CPUs supporting SSE4.2 and POPCNT instructions can still run Windows 11 perfectly well. FlyOobe bypasses Microsoft's artificial hardware restrictions, letting you upgrade unsupported PCs while keeping all your files and settings intact.

The tool includes a built-in compatibility checker that verifies your CPU supports the required instructions before proceeding.

How to Use CPU-Z

Download the CPU-Z installer or portable version and run it - no complex setup required. The program takes a few seconds to gather hardware data, then displays everything across tabbed sections.

Navigate through CPU, Caches, Mainboard, Memory, SPD, and Graphics tabs to explore each component. Use the Tools menu to save a complete report as TXT or HTML for future reference or technical support.

The benchmark feature lets you compare your CPU's single-thread and multi-thread performance against reference processors, helping you understand where your system stands.

Portable and Android Versions

CPU-Z runs as a portable application - extract to a USB drive and use it on any Windows computer without installation. This makes it ideal for technicians diagnosing multiple systems.

The Android version brings the same detailed hardware identification to smartphones and tablets, showing SoC information, device specs, battery status, and sensor data.
