Server Manager shows incorrect installed memory size in Windows Server 2012 R2

View products that this article applies to.

Symptoms

In Windows Server 2012 R2, the value of installed memory displayed in Server Manager is smaller than the actual size of the memory installed. This problem occurs when the size of a memory module is equal or larger than 32 GB.

Cause

This problem occurs because of the way memory is calculated from the System Management BIOS (SMBIOS) memory device information. Server Manager queries the Capacity property in the Win32_PhysicalMemory WMI class to get the system memory size. The Capacity property represents the total capacity of the physical memory in bytes. This value comes from the memory device structure in the SMBIOS. The Extended Size field of the memory device structure is intended to represent memory devices equal or larger than 32 GB which is not used properly to calculate the memory size.
