What is CPU-Z?
CPU-Z brings processor, motherboard and memory details into one Windows utility. Use it to identify a CPU's model and cache, check the motherboard chipset, or look up RAM timings and the specifications stored in a memory module's SPD data. Live frequency readings show how CPU and memory clocks are behaving rather than just repeating the processor's advertised speed. Text and HTML reports let you save system details for reference.
This download is CPUID's English 3.01 EXE installer for 32-bit and 64-bit x86 Windows; setup selects the appropriate binary. CPUID explicitly supports Windows 11 and offers ARM64 separately. Memory specifications need interpretation: the publisher notes that an SPD bandwidth figure can differ from the module's advertised rating when its data is programmed incorrectly or the rating depends on an extended profile such as XMP.
What it offers
- Identify processor name, model number, codename, manufacturing process, package and cache levels.
- View motherboard and chipset information.
- Check memory type, capacity, timings and module specifications stored in SPD.
- Read CPU core and memory frequencies in real time.
- Generate text or HTML system reports using command-line parameters.
Good to know
- SPD-derived memory bandwidth may differ from a module's advertised rating; CPUID attributes this to SPD programming or ratings that rely on extended profiles such as EPP or XMP.
