thanks dears above will apply also to Gigabyte RX 580 or its for SAPPHIRE only
It will basically apply to all Rx580's just take note of the memory types, as per your screencap your GPU's has hynix memory so check the Bios mod settings for Hynix, or straps, what I Always advice is that "Just don't forget to have at least backup your BIOS before doing modifications.
saving your @ss later when things gone bad.
