Miner is detecting my card as 470 but my card is Sapphire nitro+ rx 570 8GB... I am getting around 275 hash... is this okay??
Not okay, you should sell the card to me
Jks. The software shows RX500 series cards as 400 series but the speed of the card is determined by the memory type. I have a hynix RX580 Nitro+ which gives 315 hashes and an elpida RX580 Nitro+ which gives 285 hashes.
