Symptomer

In Windows Task Manager, under Memory, the values displayed for Hardware reserved and Speed may differ from what is reported in BIOS and iDRAC.

Affected PowerEdge Platforms:
14G, 15G, and 16G

Affected Operating System:
Windows Server 2019
 
Task Manager Memory

Årsak

This issue occurs because Task Manager parses the SMBIOS memory data incorrectly.

Oppløsning

Review Microsoft article:

Use the following PowerShell command to retrieve the correct output.

Get-CIMInstance -Class CIM_PhysicalMemory

ConfiguredClockSpeed matches the speed displayed in BIOS and in iDRAC.

In the below example, the PowerShell command is modified to only show the Caption, ConfiguredClockSpeed, and Speed.

Get-CimInstance PhysicalMemory
