Today is your lucky day
, I'm using hynix version of gtx1660 super too, here is the perfect settings for hynix 1660 super, 31mh to 32mh depending on silicon valley
Core clock to -502 👈 that's the lowest
Memory clock to -502 👈 that's the lowest
Power limit = 65%
That's all you need, come back and say thank you 😉
If you use Windows, then you will have the Memory clock setting -502 ,
If you use hive os, then you need to set the value to -1004
