Chrome Pin Tabs Disappear

While most issues people have seem to be with Chrome loading unwanted unpinned tabs, I want Chrome NOT to discard pinned tabs. As, the statement 'If there's a specific tab you don't want discarded, right-click on the tab and pin it.' Just does not seem to be true, in the sense, it DOES get discarded eventually when the going gets tough, as mentioned in the same page.

My question is - is there any way to prevent this, it does not even reload when memory is finally available, have to do it manually by selecting it. I pin tabs like my notes keeper, reminder service & hangouts (for SMS) so I can get notifications in real time. Bitcoin paper wallet designs best paper wallet for mac.
