Dynamic Memory is the feature that enables a virtual machine (VM) to start with an initial startup RAM value that can be higher than the minimum necessary RAM value needed for operation. This capability allows Hyper-V to dynamically adjust the amount of memory allocated to a VM based on its current workload and requirements.

When Dynamic Memory is enabled, the VM can initially boot up with a larger amount of allocated memory, which allows it to run efficiently under peak usage conditions. As the workload decreases, Hyper-V can reclaim the excess memory and allocate it to other VMs that may need it, effectively optimizing the use of physical memory resources on the host server. The ability for a VM to work with a lower minimum RAM value allows for greater flexibility and resource efficiency in environments where workloads can vary significantly.

This is particularly useful in environments with multiple VMs, as maintaining an optimal memory allocation can improve overall performance and resource utilization, preventing wastage of memory on less active VMs. Other memory management options such as Static Memory do not provide this flexibility, as they allocate a fixed amount of memory at all times, while Memory Overcommit refers to the practice of allocating more virtual memory than physically available, which can lead to performance issues if not managed properly.
