CpuZeeZ 0.3.0

A redesigned interface, a hardware monitor, memory and cache benchmarks,
device health, and closing most of the remaining gaps with CPU-Z.

Added

• New interface.
  • Sidebar navigation with full pages: Overview, Processor, Mainboard, Memory, Graphics, Devices, Sensors, Benchmarks, Tools, Settings and About.
  • Card-based layout and Phosphor icons.
  • The operating system's own UI font (Segoe UI, SF Pro, Cantarell, Noto, Inter…).
  • Light and dark themes with the brand violet accent.
• Overview dashboard. The system at a glance: CPU, GPU and chipset temperatures and the CPU clock with live sparklines, a health and throttling status, and one card per component.
• Translations. The interface is available in English, Brazilian Portuguese and Spanish, picked from the OS language or chosen in Settings. Reports stay in English, like CPU-Z's.
• Settings page. Language, theme, tray icon, close to tray, sampling period, graph history, warning temperature and data folder. Settings are saved per user.
• Sensors page. An HWiNFO-style monitor:
  • Every sensor, grouped by device (CPU, GPU, mainboard, chipset, memory, storage, battery), with current, minimum, maximum and average values and search.
  • Live charts with hover values.
  • Temperature colouring against Tjmax.
  • CSV logging.
• Monitored stress test. Live temperature, effective clock, package power and GPU temperature. It warns when thermal, power or current throttling is detected and stops automatically at a temperature limit.
• Throttling detection.
  • Intel: thermal status and limit-reason MSRs.
  • AMD: Tjmax and PPT/TDC/EDC limits.
  • Linux: the kernel's throttle counters.
  • GPUs: their throttle reasons.
• Tray / menu-bar mini monitor. The tray icon shows the CPU temperature. There is also an always-on-top mini monitor window on every OS.
• Memory and cache benchmark.
  • Latency from 4 KiB to 1 GiB, which reveals L1, L2, L3 and DRAM.
  • Read, write and copy bandwidth per cache level and for DRAM, single- and multi-threaded (-membench).
• Benchmark history. CPU and memory results are saved locally with a label, with charts over time and comparison of two runs.
• Compare reports. A diff between two JSON reports, or between the current system and a saved report, that ignores live values unless asked (-diff=OLD.json,NEW.json|now).
• Devices page.
  • Full SMART for NVMe and SATA: health, attributes, temperature, wear, hours and data written.
  • Battery health: design and full capacity, wear and cycles.
  • Network adapters: link, MAC, IPs, gateway, DNS, driver and Wi-Fi details.
• AMD SMU decoding, Zen 2 to Zen 5:
  • Per-core, L3 and SoC temperatures.
  • VDDCR_VDD, VDDCR_SOC and VDD_MISC rails.
  • PPT, TDC and EDC.
  • FCLK, UCLK and MCLK, Fmax, and per-core max effective ratio.
• Intel memory timings from the memory controller, Skylake to Arrow Lake: CL, tRCD, tRP, tRAS, tRFC, command rate, gear and the memory controller clock.
• Mainboard sensor maps for more than 150 ASUS, Gigabyte, MSI and ASRock board models, plus generic maps per Super I/O chip. The CPUZEEZ_EC_DUMP helper and an issue template make it easy to contribute new boards.
• Chipset temperature.
  • Intel: the PCH sensor (PawnIO IntelPCHThermal, Linux intel_pch_thermal).
  • AMD boards: when the board routes it to the Super I/O.
• GPU sensors.
  • Hot spot and memory junction temperatures, fan RPM and duty, power, load and throttle reasons.
  • NVIDIA memory vendor, via NVAPI.
• Uncore and fabric clocks (AMD FCLK/UCLK, Intel ring), the memory controller frequency and the PCIe "Bus Specification" on Windows.
• One-click update. The update banner downloads the right installer for your OS and CPU and verifies its SHA-256 against the release's SHA256SUMS.txt before launching it.
• New command-line options: -sensors, -log=FILE[,SECONDS], -membench, -diff=….

Changed

• The reference clock is measured from the TSC and the base ratio, so memory and uncore frequencies follow the real BCLK.
• ITE Super I/O voltage steps match the published board tables.
• Reports gained Batteries and Network sections, SMART groups under Storage, and Sensors groups under each display adapter.

Fixed

• macOS, thanks to @vinicius741:
  • The standalone universal CLI (in the .pkg and .tar.gz) is now ad-hoc signed for both architectures, and the release workflow verifies every shipped signature. Updated Gatekeeper instructions for macOS 15+ (#1).
  • Memory capacity and type on Apple Silicon, which has no SMBIOS memory records (#2).
• Links and the "Download" buttons now open the browser.
• Overview cards no longer show empty separators when a value is unknown.

Downloads

Platform	File
Windows 10/11 x64	.msi installer, or the -portable.zip
macOS 11+ (universal: Intel + Apple Silicon)	.dmg (app) or .pkg (app + CLI in /usr/local/bin)
Debian / Ubuntu	.deb (amd64, arm64)

Verify downloads with SHA256SUMS.txt.

Notes

• The installers have no publisher certificate:
  • Windows: SmartScreen → More info → Run anyway.
  • macOS: executables are ad-hoc signed, but not Developer ID signed or notarized. Check SHA256SUMS.txt, attempt to open the app or .pkg, then use System Settings → Privacy & Security → Open Anyway and confirm Open. On macOS 11–12 use System Preferences → Security & Privacy → General. Repeat for the installed app if prompted. Right-click → Open no longer bypasses Gatekeeper on macOS 15 and later. See Apple's instructions.
• Windows: install PawnIO and its modules, then run as administrator, to get MSR, SPD, memory timings and Super I/O sensors.
• Linux: run with sudo (and modprobe msr i2c-dev) for the same.
• The benchmark is cpuzeez's own workload: scores are not comparable with CPU-Z's.

Full changelog: CHANGELOG.md

CpuZeeZ 0.2.0

What's new in 0.2.0

• New name and logo: CpuZeeZ. The app has an icon everywhere: cpuzeez.exe (with version info), the window and taskbar, the Start-menu shortcut, Installed apps, CpuZeeZ.app on macOS, and the Linux desktop entry with hicolor icons. The binary and package names stay cpuzeez.
• Update notice.
  • At startup, CpuZeeZ checks GitHub releases once (an anonymous request). If a newer version exists, it offers a one-click download of the installer for your OS and CPU.
  • You can also use About ▸ Check for updates, or cpuzeez -checkupdate.
  • Turn it off with CheckUpdates=0 in cpuzeez.ini.
• Windows: no more console window when you start the GUI from the Start menu or Explorer. Command-line options still print to the terminal you run them from.
• Upgrading on Windows: run the new .msi over the old version. It upgrades in place (one entry in Installed apps), and downgrades are refused. CI now tests install → upgrade → downgrade block → uninstall on every push.
