Yup gpu-z should do. Now check with +100 to +150 on core and see if you attain similar clocks on 19xx range.
The 1060 I have is from 1741 so late 2017 - quite surprising that it has samsung memory. I have a 1070 with samsung memory and that one is from late 2016. Maybe someone found some old memory stocks in the factory

That's lucky of you.
I just wonder with what kind of memory you get these cards when they can reach +1000. My Samsung cards cannot exceed +700 when mining ETH. Hynix cards cannot go above +450, +500 is like winning a gold medal. Maybe I do something wrong.
Actually Hynix can do +750 but they have pretty loose timings so it's not fruitful. They don't go past 20.5 even at +750 MHz on memory.
