The stepup is 90 days, but you have to register the card within 30 days.
Hmm, after reading through it, i guess stepup doesnt seem to care when you register it or not. I still recommend registering in 30 days because if you dont stepup, you get the lifetime warranty, which IS 30 days.
All EVGA Products purchased ON or AFTER November 1, 2006 MUST be registered within 30 days from ORIGINAL DATE OF PURCHASE to receive limited lifetime warranty. (All products not registered within 30 days will ONLY receive a 1 year limited warranty.)
