Can anyone id this gpu?

I bought the gpu on eBay as a 1060 to put in an oem, but it’s not a 1060. There aren’t enough ports and it doesn’t run as fast as it should. It only recognizes it as a 1060 5gb version in device manager after I install drivers, but nvidia won’t recognize that the drivers are installed. Idk what it is, and the guy I bought it from gave me a full refund for it so no big deal I’m just curious.
