This question already has an answer here:
In "The Day of The Doctor", the Doctors agree that they won't remember trying to save Gallifrey, but other information around this site has made me think otherwise. Will any of the Doctors remember attempting to save Gallifrey rather than burn it?
WARRIOR: I won't remember this, will I?
DOCTOR: The time streams are out of sync. You can't retain it, no.
WARRIOR: So I won't remember that I tried to save Gallifrey rather than burn it. I'll have to live with that. But for now, for this moment, I am the Doctor again. Thank you. Which one is mine? Ha!
So, will he eventually remember?
Oh, and before anyone answers this: I know, "timey wimey."
