Memory Preferences

Preferences Memory

On this tab maximum amount of physical memory (RAM) that system should reserve to all simultaneously running virtual machines on your computer can be adjusted. This setting applies to all users of your computer.

The maximum memory allowed depends on physical RAM size of your computer. Some memory must be reserved for your primary operating system. From the remainder you can select the maximum RAM allowed for Parallels Workstation. If you have one instance of virtual machine running, it may use all the memory allocated here. In case of several simultaneously running virtual machines this memory will be shared between them. Memory for a specific virtual machine is set on the Memory tab in Configuration Editor.

Memory amount should be multiple of 4. If it doesn't then you will receive error notification when trying to save memory options. To set an appropriate memory amount you may use the slider, the spin buttons in the Reserved memory limit field, or type a value directly into the field.
