I think you mean this one?
It doesn't appear to give a solution. My one is also a sapphire RX 570, so it seems to be a widespread issue. Anyways, the computer appears to be working normally with the latest drivers (and calling the card an RX 580), so until there is a fix I am leaving it as is.
I also noticed that the card came with an "overclock" sticker on it, maybe it is preloaded with a 580 clock speed/bios or something? (i have no clue what im saying here, but seems right based on other forum sites)
