When you select a custom configuration, the New Virtual Machine wizard prompts you to specify the default settings for memory allocation.

Color-coded icons correspond to the maximum recommended memory, recommended memory, and guest operating system recommended minimum memory values. To adjust the memory allocated to the virtual machine, move the slider along the range of values. The high end of the range is determined by the amount of memory allocated to all running virtual machines. If you allow virtual machine memory to be swapped, this value changes to reflect the specified amount of swapping.

The maximum amount of memory for each virtual machine is 64GB.

The total amount of memory that you can assign to all virtual machines running on a single host machine is limited only by the amount of RAM on the host machine.

You can change the amount of memory available to all virtual machines by modifying Workstation Pro memory settings.
