Hello,
To increase your virtual machine's RAM volume:
1. Open your virtual machine list (virtual machine should be not running) - Right click on the Parallels Desktop icon in the Dock -> Virtual Machines List.
2. Right click on the needed machine (if you have multiple) -> Configure ...
3. in General tab you will see "Memory" -> now you able to manipulate it.
Regarding the Power Safe mode: its automatically goes to save the power if your Mac is not connected with the power cable (working on internal batteries). It is not related to the Random Access Memory (RAM).
