what does OCing the Mem Clock do?
and what is a safeish OC for a 2070 Gaming Z In your opinion?
It doesn't do much, the Core clock is more important on Nvidia cards (but on amd vega memory clock is important),
I have no idea about the 2070, because it has the gddr6 memory.
I recommend looking at some 2070 overclocking videos to see some examples.
