Argentina fly-half Benjamin Urdapilleta set a new individual points record for the Top 14 on Saturday, scoring 33 points in Castres' 48-17 win over Montpellier.
Noa Nakaitaci scored a hat-trick of tries for Lyon but ended up on the losing side against Racing 92 while former New Zealand sevens international Ben Lam scored his first try since December as Bordeaux-Begles hammered Stade Francais 44-6.
Urdapilleta scored a try in each half and kicked four out of five conversions and five penalties to eclipse the 32 points scored by Cedric Rosalen for Narbonne in 2006-2007 and Bayonne's Benjamin Boyet in 2012-2013.
"For the record, I didn't know," he joked after the game. "I knew I had scored ten points with my two tries, but penalties, conversions, I don't keep count. Thirty-three points is good for confidence, but I'll remember the victory above all else."
"In the warm-up, I missed a few penalty kicks, but on the first kick in the match, I had a good feeling, the second one was the same, I asked myself: 'will I kick 100 per cent today?' But I put the last one against the post, maybe I put a little pressure on myself."
Filipo Nakosi, Rory Kockott and Bastien Guillemin also crossed for Castres who clocked up their eighth win of the season. Montpellier remain 12th in the table.
Racing 92 moved up to provisional second in the table as Teddy Baubigny, former Ireland wing Simon Zebo and ex-France fly-half Francois Trinh-Duc scored tries in a 34-26 home win over Lyon.
The man of the match though, was undoubtedly the Fijian-born France centre Nakaitaci who crossed twice in the first half and again just after the hour.
Lam, who joined Bordeaux from the Hurricanes this season, crossed as did lock Cyril Cazeaux, winger Romain Buros and Kiwi fly-half Ben Botica, who also kicked 22 points.
The home team, without France Six Nations squad members Cameron Woki and Matthieu Jalibert, dominated the opening quarter and led 16-3 after Cazeaux crashed over.
Bordeaux-Begles led 22-6 at the break as Botica added two penalties after two Joris Segonds efforts for the visitors.
Ten minutes into the second half Botica crossed in style.
Then substitute Jean-Baptiste Dubie off-loaded to Lam who crashed over in the left-hand corner with less than 20 minutes to go. It was his fourth try this term.
Buros added a fourth try to rubber stamp the bonus point win.
Later, two-time Rugby World Cup winner Victor Vito takes his La Rochelle side to Toulon looking to close the gap on top-of-the table Toulouse.
On Friday, South Africa's World Cup winner Cheslin Kolbe added a ninth try for the campaign in the leaders' 31-9 win at Pau.
