Hello Sirs,

I have overwrited the bios of Sapphire Pulse Radeon RX 570 8G MICRON BIOS ROM by RX470 4G ROM.

Then I found the original rom of RX570 by googling but it is not working on my video card. I guess it is not for MICRON RAM.

Is there anybody using Sapphire Pulse Radeon RX 570 8G MICRON? Please send me the original bios or the moded bios for Sapphire Pulse Radeon RX 570 8G MICRON BIOS ROM.

My e-mail is dosik99@gmail.com.

Thank you so much in advance.
