Actually it depends on how much Ram you have.
And by the way I said both min and max.
But I have a better solution (that helps all)
Set it to Automatic
Save (apply OK .. any other OK)
Restart
Also, do not post twice in a row, any more (ok) !
If you HAVE to post again use EDIT, but not if the previous post is mine, just use reply
ie don't reply to yourself
edit:
I mean System Managed size (not automatic) !
