The PNY version of gtx1660 super with a single fan is hashing at 33mh, this is so real but the Zotac and Asus versions are doing 31 MH on my rigs, I guess there is more we don't know about all these gpu manufacturers than we think, anyways 2MH difference isn't even much to begin with
my 1660S works with fixed 0,64 vgpu, pp 100%, vram +1000, vcore -100 and i get 32mh@80w
