It could also be that the MCDU entered weight differed a lot from the actual weight calculated by the FAC during climb.
You will get an error message "CHECK GW" on the MCDU only if the MCDU and FAC values differ by more than 7 (seven) tons. That could make for a lot of speed! A finger trouble or a W&B miscalc could easily make up for that. If the weight is/was verified to be absolutely correct (is it a word in aviation?..) then the AOA probes may need a check up.
Just a guess.
