A simple and lightweight app for monitoring memory timings on Ryzen platform.

ZenTimings shows you all the important memory timings, voltages, Infinity Fabric and Memory Controller clocks. No matter the motherboard vendor, the app should help you see what DRAM parameters are applied.

Latest v0.0.0 for Windows

Display commont timings available for adjustment in BIOS.

Get a quick glance on hidden timings.


Provides an optional realtime monitor for FCLK, MCLK, UCLK clocks and memory-related voltages.

Supported features vary between different SKUs and motherboards..


Save a screenshot of your current settings and share it to help other users.

Share a debug report to help with the development.

How To

This short how-to should get you started.

System Requirements


Extract the downloaded archive anywhere on the disk.
InpOutx64 driver gets automatically installed on first launch.
Location of the installed driver is /System32/drivers/inpoutx64.sys.

To uninstall the driver you may use a manual method or a utility such as Autoruns for Windows.


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.


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.


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.


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.

Debug Mode

When certain things 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.


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