EVGATech_MattMWelcome to the forums. If you received it before May 25th we can assist with a Standard RMA without an invoice. Please have the card registered and your address information up to date on your account then submit a ticket for the card at Service->Support Tickets saying what the issue is and what testing you have done and we can assist you from there. I apologize for any inconvenience.
EVGATech_MattMThis is fine as it is before May 25th of this year. You can see the the full warranty terms it falls under .
