When you view memory information in Windows Task Manager, the values that are displayed for reserved hardware and for speed may differ from what is reported in other sources. For example, Task Manager may show the memory speed to be higher or lower than the speed that is reported in the BIOS.
This issue occurs because Task Manager parses the SMBIOS memory data incorrectly.
To work around this issue, use an alternative source to view memory information. For example, Resource Monitor displays the correct value of the hardware reserved memory and is included in Windows 7 and later versions.
