Josh Van Der Flier scored twice as Ireland capped a fruitful autumn by grinding out an emphatic 53-7 win over wasteful Argentina in Dublin.
Fellow forwards Andrew Porter, Caelan Dories, Dan Sheehan, Cian Healy and Tadhg Beirne also claimed tries to help Andy Farrell's men stretch their unbeaten run to eight games.
Meanwhile, the exceptional Joey Carbery - filling in for injured skipper Johnny Sexton - backed up his match-winning cameo in last weekend's stunning success over New Zealand by kicking 18 points.
Los Pumas have history of upsetting Ireland following three shock wins at World Cups but faded fast from a promising start as their record of never having won at the Aviva Stadium continued.
Mateo Carreras' early try was all Mario Ledesma's men had to show from a difficult afternoon, while lock Tomas Lavanini was dismissed 20 minutes from time for a dangerous challenge on Irish replacement Ryan Baird.
The visitors' hopes of avoiding a 14th defeat of a difficult calendar year were not helped by a bizarre spell of first-half profligacy during which Emiliano Boffelli somehow squandered two simple penalties and Carreras was denied a second score by an unexpected fumble.
