Given how finicky RAM can be without errors showing up, the fact that you received any errors at any time means you should send back the kit ASAP, especially since it is still covered by Amazon. Get a kit that is guaranteed for your board by Gigabyte and by the RAM manufacturer.
Glad to hear you were careful with static. I have an antistatic mat and antistatic wristband, so I appreciate your precautions. I usually give the static precautions warning because most people are not aware of how easy it is to damage components with static electricity and the fact that it does not have to be felt to cause damage.
Anyway, send the RAM back to Amazon for a refund and find something that is definitely compatible with the board.
