How To

This short how-to should get you started.

System Requirements

  • AMD Ryzen, Threadripper or EPYC processor
  • .NET Framework 4.5 or newer (v3.5 for the legacy app)
  • WinRing0 (bundled with the app)
  • InpOut (bundled with the app)
  • Supported OS: Windows XP*/2003*/Vista/7/8/10/11 (32bit and 64bit)
    * Note: Windows XP and 2003 only supported with the legacy app

Installation

Extract the downloaded archive anywhere on the disk.
InpOutx64 (WinIO for 32bit OS) driver gets automatically installed on first launch.
Location of the installed driver is /System32/drivers/inpoutx64.sys (/System32/drivers/WinIO.sys for 32bit OS).

To uninstall the driver you may use the provided uninstall_inpoutx64_driver.bat script (run as administrator), a manual method or a utility such as Autoruns for Windows.

Functions

Common Timings

The main purpose of the app is to show all the impotant timings info on a single screen. Currently it's in read-only mode, since adjusting timings on-the-fly is not possible on Ryzen, without a reboot.

Due to differences between CPU generations, BIOS versions and motherboards, some parameters might not be detected, although the timings should be available on all platforms, including mobile APUs.

Frequencies

Infinity Fabric and Memory Controller clocks can be detected on most of the desktop SKUs, however the values are not aware of current base clock (BCLK). ZenTimings will make an attempt to correct them, but it will work in limited cases, where configured DRAM frequency is reported correctly. Result will vary between different BIOS implementations and AGESA versions.

Voltages

The app tries to read several voltages related to the memory controller, but again, it all depends on the platform and the information BIOS is reporting.

Screenshot

A screenshot of the app window can be automatically saved or copied to clipboard with a click of a button.

Auto Refresh

Auto Refresh is enabled by default and updates frequencies and voltages every 2 seconds. The feature can be disabled from the Options dialog. The interval is user-configurable.

Themes

Supports different themes, which can be changed runtime.

Debug Mode

When certain parameters are read wrong or not displayed at all, a handy debug window provides an essential info which might help the developer. Please don't hesitate to share the report.

Thanks

Last, but not least, a big thank you to all the people who provided valuable debug reports and feedback.

Q: What is ZenTimings?

A: ZenTimings is a dedicated app for displaying DRAM-related timings and other parameters on AMD Ryzen platform.

Q: What are the supported processors?

A: All Ryzen-based systems are supported, but not all parameters are available on every one of them.

Q: VDIMM is not displayed, why?

A: I haven't found an easy way to read the voltage. Other tools like HWInfo have the abillity to read from I2C bus of various Super I/O chips used by motherboard manufacturers and ZenTimings doesn't. There are no plans for implementing that feature.

Q: Some of the parameters are not displayed on my Ryzen-based laptop.

A: That's a known limitation. Laptops don't seem to expose the AMD ACPI WMI class, where these parameters are read from.

Q: The app is running in compatibility mode.

A: The app runs in compatibility mode when no AMD ACPI WMI class is found on the system.

Q: Controller settings are displayed as N/A on my Threadripper.

A: This happens on some systems and I don't know the reason. It's probably related to fTPM, but I don't have a fix for it at the moment.

Q: VDDG CCD or other voltage is displayed as N/A.

A: The supported voltages that can be read vary based on the CPU and platform. For example, there's no VDDG voltage available on Zen and Zen+.

Q: Can you make the same for Intel?

A: No.
