RX 580 reachig 4.7mh/s is possible only if you have free electricity. The thing is in this miner they made it so much core clock intensive that it's the only thing affecting hashrate. For example i was playing 15 hours yesterday in order to tune my 2 trigs all rx 580 - 8gb mixed memory. I found out intensity is best on 22 and worksize on 0, yea when ever i put 22x128 or 21x128 one of my cards would stop hashing after brief period of time. Also i would like to say that if you put them at 1366 or even better 1411 core and 2100 memory you will get promised 4.7mh/s but with a lot power consumption. I then settled with 4.3-4.5mh/s in following clocks.

My first rig uses only micron memory which i found to work best on 1366 and 2100 memory, each card using about 125-130w at wall. I get 22.3mh/s from 5x cards so average about 4.4mh/s and 715w at wall whole rig.

My second rig uses mixed samsung and hynix memory on almost every card, i found best values at 1280 core and 2150 memory, they hash me 26.2 mh/s for 6 cards. Rig uses 850w at wall aproximate (spikes from 830 to 865).

Also i had eth bioses at all cards, i opened Polaris Bios editor and clicked one time patching and changed core clocks in bios for some cards in order to make it more stable and not mess a lot in MSI Afterburner. Then when i updated bioses via one click timing patch button, saved them and used ati win flash to flash newly bioses to gpu. Now all is stable and got it to work but had a lot of pain until i figured it out. Got random hangouts of gpus and wrong values made my rigs very unstable. So 4.7 is on paper if you have very cheap electricity and your psu can take it.

What new miner is on for lyra2z and cnv8? Can someone tell me?

I found that bios mod is only good for eth and cn everything else I mine I run stock bios at least for rvn, phi2 and lyra2z ya it's a pain to have to flash but you'll run better rates a less watts I don't even overclock I run stock clocks also
