Looking for suggestions on GTX 1660 Super OC settings … thank you in advance!

Been mining ETH but everyone mines it and I ran across RVN. Reviewed the latest dev notes and after more research decided I’m in. But when using optimal settings for ETH they are not working so well with RVN. Stock gets 14-15mh while ETH settings get 11mh with RVN.

Core: -200 Mem: +1150 PL: 53 5x Samsung and 1 Hynix (runs at mem +650) 

Those settings get me 32mh per card @ 70w with ethash.

Thanks!
