Are both flights on the same ticket? If they are on the same ticket and your first flight is delayed it will be up to airline in Amsterdam to sort out an alternative to getting to Malaysia, i.e. another flight same day or following day etc. If you booked everything on the same ticket and the booking system allowed a one hour connection, then a one hour connection is legal and possible, though very tight.
If on the other hand they are not on the same ticket i.e. you bought one ticket for Amsterdam to Malaysia and a separate ticket for Dublin to Amsterdam, then you are screwed if there are any hiccups and you get delayed. If I buy separate tickets I usually allow 3hrs connection time.
