I have a rig with a 6xRX480 Asus.
I am with a dag driver.
Gore clock is 1160.
Mem clock is 2020.
The speed is 4511 h/s.
Is this ok or a need to change something to have a better performance?
This sounds right, my rx 480 gets about 750 h/s so if you x that by 6 it would be 4500. Monero mining uses a lot less power than ether dual mining which is nice. More stable too.
