A free, 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.

Display common 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.
Supported OS: Windows XP/2003/Vista/7/8/10 (32bit and 64bit)
Extract the downloaded archive anywhere on the disk. InpOutx64 (InpOut32 for 32bit OS) driver gets automatically installed on first launch. Location of the installed driver is /System32/drivers/inpoutx64.sys (/System32/drivers/inpout32.sys for 32bit OS).
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 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.
Supports light and dark modes, which can be changed runtime.
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.
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+.
