What would be the most stable settings for the XFX RX580 8gb?

I'm currently mining with 4 XFX RX580s using the settings I use for Ethereum. Since it's a different algorithm it's been making my mining rig heat up a bit more and consumes more power and I was wondering what the most optimal settings would be for these cards. These are my current settings that I use:

Core clock: 1150 Core voltage: 880mV Memory clock: 2050 Memory voltage: 880mV Fan speed: 65%
