Review: Sapphire Radeon RX 580 Nitro+ Limited Edition

There isn't a whole lot left in the tank, captain. The core is only stable at 30MHz higher but memory is more partial to overclocking, coming in at 9GHz.

You don't get much extra, truth be told, so we'd be tempted to leave it at the out-of-the-box clocks.
