Symptoms

Server Manager displays an incorrect amount of installed memory in a Generation 2 virtual machine when the random access memory (RAM) that's assigned to the virtual machine is 36,736 megabytes (MB) or more. If the virtual machine is assigned more than 36,736 MB of RAM, Server Manager shows that the system only has 3.88 gigabytes (GB) of RAM installed.

Cause

This problem occurs because of an issue in the Hyper-V virtual machine UEFI firmware.
