I might experiment later on when I decide to drop $80 for the MCX478. But I really don't want that damn Delta on there 😀
That said, I think 1.75 is OK. As long as the temperatures are kept in line, you shouldn't have any trouble. 10% is usually the recommended max for overvolting (which would be 1.65v) but I don't why (so long as the temperatures are kept in check) 1.75v would make any difference. The chip will be past its time before it would die from a little extra voltage. 🙂
