Memory will overclock more than the core clock itself. If it doesnt crash and remains stable then you have sucessfully OC'd it 600 Mhz

Wasap there . 
I was overclocking my gtx 1660 super using msi afterburner and I got shocked by something. I was tuning my gpu core and memory frequency and by mistake i added 640 mhz to the memory clock . But the pc didn't crash! So I did a benchmark and it still didn't crash at all . I am new to overclocking . This is my 2nd time . So I am worried if this is not safe. Plz if u could help I would be thankful. 

I went for the Ryzen, 1660 super, 550w psu. Thanks for the feedback!

Wait because amd is going to sell the 4000 series later this year

If its not in stock then there's not much you can do. You can either wait and see or just get the 3100. The 3100 will be plenty at this price point, as you're better focusing on a better GPU for gaming anyway. You could also look into the Ryzen 5 2600 or 1600AF (12nm) if they are available cheaply, or second hand

we dont know until benchmarks are out
