Microsoft is testing the display of memory speeds as MT/s (mega-transfers per second) rather than MHz (megahertz) in the Windows 11 Task Manager.
Historically, the data transfer speed of computer memory has been advertised under the MHz (megahertz) metric. MHz represents how many millions of cycles per second a memory module can perform, with each cycle being an action conducted on the memory module, such as storing and retrieving data.
For example, a memory stick running at 3,200 MHz can perform 3.2 billion cycles per second compared to memory running at 2,400 MHz, which can only perform 2.4 billion cycles per second.
However, new technologies have allowed DDR memory to increase the data transfer rate without increasing clock speed (MHz), making the old way of measuring memory less accurate.
Since then, companies and operating systems have migrated to a performance metric called MT/s (mega-transfers per second), the number of data transfers in millions per second.
As first spotted by Windows sleuth PhantomOcean3, Microsoft is now testing showing MT/s instead of MHz in the Windows 11 Task Manager performance tab.

This feature is currently being rolled out in the Windows 11 Beta preview builds as part of build 22635.3570.
However, if you wish to test this feature now, you can use ViVeTool to enable it using these instructions:
- Download ViVeTool and extract it to a folder.
- Open an elevated command prompt and change into the folder you extracted ViVeTool.
- Type this command and press enter:
vivetool /enable /id:38476224,48380607 - If the Task Manager does not show MT/s, you may need to reboot Windows 11.
It should be noted that enabling these features using ViVeTool could cause instability on your device.
If this is a production computer, you may want to wait until the feature rolls out to your device rather than manually enabling it.
Update 5/6/24: This article originally stated it was a hidden feature. It is rolling out to all Beta insiders.
