Chip Identification

Would anyone be able to tell me what the small chips are on a SAB-001 board, there’s 7 in total, 4 in a line next to each other then a gap and 3 more next to each other and they have “470 45AQJ d” printed on them, located below the APU chip and RAM chips. Also would these having any damage cause the system to not boot? (I do have pictures but it says I’m not allowed to post images)
