CPU-Z v.2.20.2

CPU-Z provides detailed information about the processor, including its name, architecture, core voltage, clock speed, cache levels, and supported instruction sets. It also identifies the motherboard, BIOS, memory configuration, individual RAM modules, and basic graphics hardware details.

CPU-Z usually shows the actual memory clock, while DDR memory transfers data twice per clock cycle. For example, a reading of 1600 MHz corresponds to an effective DDR4-3200 speed of approximately 3200 MT/s. This difference is expected and does not indicate a problem.

Open the SPD tab and select a memory slot from the slot selector. CPU-Z can display the module manufacturer, part number, capacity, supported JEDEC profiles, and, where available, XMP or EXPO profile information.

No. CPU-Z is designed primarily for hardware identification and does not provide comprehensive temperature, fan-speed, or sensor monitoring. Use a dedicated hardware-monitoring utility when you need live temperature readings.

Press F7 to save a text report containing information from the available CPU-Z tabs. This is useful when documenting a system configuration or sharing hardware details for troubleshooting.

No. The built-in benchmark performs a short processor performance test and allows the result to be compared with reference scores. It is not a replacement for a prolonged stability or stress test.

Yes. The portable package can be extracted and run directly from a chosen folder or removable drive. Select the executable that matches the required architecture, if more than one version is included.

Validation creates a record of the detected hardware configuration and benchmark information. It can be used to document a system or share its specifications with another person.
