The advantage @Populos is that if your phone starts to max out the 12gb built in Ram then it can then use the virtual Ram you've added.
Personally I find my phone adequately self regulates my Ram to free up some Ram if required.
People have read that it has the potential to slow down the phone however I haven't personally seen anything official about this.
I don't use Ram- Plus.
If I can be of any further help then please don't hesitate. Take care. 😎
