that card isn't designed for gaming or overclocking. don't push it hard or it won't last much longer.

your core is much to high, the voltage wont kill the card as it wont increase high enoug. But head defiantly could. Also the 620 is a very fine card for the upper lower range but isnt manufactured with ocing in mind. There for has no room specs wise to do anything

Do you know some good oc settings for the 620?

go 760 on the core and 550 on the memory. Safe and should be stable
