For sure REF 30 is less agressive than REF 20
If your memory accept REF 20 it for sure accept REF 30
Lower is better
Are you sure lower is better because if i dont set it to 20. It works with 5 also the hogher it goes the more mhs i get but just slightly. I have tested with 200
today i tested some settings and mods and i came to the following:
with uber 3.2 bios timings in the polaris bios editor and with settings 
Core clock 1168, core voltage 850, memory clock 2100, memory controller voltage 800, aggressive undervolting on and ref rate 35 - i get 32.20 Mhs with 102 watts power ( silicon lottery on this rx 570 Asrock )
i have the same brand, memory and so on… no improvement. now running on stock and overclock gets 17.92mhs
manage to get any break thru…please share
just get it modded with polaris and OC it. same as your settings but remove the DPM states. put --REF 30 and you can try the mem clock higher if it lets you.
Appreciated if anyone can share Mod Bios for AFOX RX 580 8Gb Samsung K4G80325FB , I had try to do by myself with Polaris Editor and flash on my card but when I oc it not over 27MH, I need 30-32 MH.
First of all power limit function is not working for these cards. Then the DPM states also. Dont use them. Trg with oc settings 1150 core clock 850 core voltage, 800 memory controller voltage and 2100 memory clock. All the rest should be empty. Also switch on the aggressive undervolting and use the amdmemtweak - - ref 20

hi there Netiya i saw your post can you tell me did you use the standard cards or did you flashed the memory somehow
thanks
This!!!
What?
You have any suggestions for me? My rx580 is driving me crazy!! I can not bios mod on hive. It has dual bios and the switch is on mining I think. It’s away from the power plug. Currently at 1100/1/850/2000 ref 30 aggressive undervolt.
why cant you bios mod it?
try core clock 1150 , remove DPM state, core voltage should be 850 or 860.
memory controller voltage should be 800, memory clock 2050 for now.
test and let me know.

Not sure i get the error. AMD VBIOS saving failed. When I try to save original bios. I tried both bios.
Should I keep ref 30 and aggressive undervolt?
yeah you need these two also.

you may need to hook it to windows PC and flash it there. maybe there is a problem with the amdVBFLASH version 4.71 or with this version of HiveOS.
