Mining ETC with 2 RX 580 4GB Cards

Hello, Just wanted to get some advice with tuning this a bit. I’m brand new to mining. The rig has 2 RX 580 4GB. Using lolminer on Hivepool. They are connected via risers to an Asus MB. Things are working fine but would like some advice on tuning this a bit to get a better hash rate. Tried ETH but couldn’t get much out. At least breaking even with ETC.
