Rampó was the count of Barcelona from 820 until 825. After the mandatory deposition of Berà, Emperor Louis I the Pious considered it prudent to entrust Berà's honors (or rather his counties) to a noble man far from the factional struggle that had developed in Gothia. He chose the Frank Rampó, who had already faithfully served Charlemagne, and who had been charged to communicate the death of the Emperor to his son Louis I, then king of Aquitania, in Doue (Anjou) at the beginning of 814.

It is believed that Rampó governed in Barcelona, Girona and Besalú, and was titled Count and Marquis, the latter title reserved only for the rulers of the border counties. In 821 the court of Aachen ordered him to ransack Muslim territory, an order which he had to carry out 822, up to the river Segre. It is believed that Aznar I Galíndez, count of Urgell and Cerdagne and former ruler of Aragón, also participated in this expedition.

Rampó probably died in the year 825. Not until an assembly in Aachen in February of 826 did Louis I designate a replacement. The man elected to the position was the chief of the war party, Bernat of Septimania, the younger brother of Gaucelm of Empúries and Roussillon.
