3.33V for both
history, sicky substance around c3890 area

unrelated question, I have fixed almost every air board thats come through here, and around 70% of retina boards but these I rarely fix them without help, why are these such bullshit compared to the retinas and airs

Check for pulsing on 5V_S3 rail, measure carefully preferably with a scope. Auto range meter will not catch these.
