Asus Rx 470 mining.Cant find any datasheet for two chips.

[Noovas]

Hello, friends
I have one not working graphic card (Asus Rx 470 mining), which I am trying to repair. There are two chips which I am reading clearly but can't find anything about them. Google just says nothing for both of them. One is AMCH675 and the other one is 71630VSW. I tried different variations of tipping but without success. I am uploading a photo for each of them. I will really appreciate if someone can help....
Thanks

Only your theme needs to be moved to the graphics section. https://www.badcaps.net/forum/forumdisplay.php?f=14
