remove the memory voltage value. its not working for RX 5xx cards.
Memory controller voltage should be 800. test it.
Core states doesnt work so remove the value also .
Switch aggressive undervolting on.

Dude i see all are samsung and if you did everything correctly with polaris bios editor and used the uber mix 3.2 timings use the following settings :
Core clock 1168.
Core voltage 860-875 ( depents on the cards )
Memory controller voltage 800
Memory clock 2100
Aggressive undervolting on
amdmemtweak --Ref 20
Do not input any other settings like Core states mem states , mem voltage, they dont work on rx 5xx.
Quite a big difference in “Hive” Wattage.
So set state have impact on Polaris allso
With mdpm 1
Without mdpm or MVDD set
Miner screen mdpm 1
Miner screen mdpm 0
Imho u need to set core voltage and memory MVVD

set it manually to 800 820 830. otherwise its 1000
two cards from teh same manufacturer doesnt do the same watts there is always difference in the quality of the silicon from one another.
these are screenshots from same rig with mdpm 1 and 0.
There is clearly effect on mdpm…look at the wattage man
did it like that, doesn’t work for me. damn i feel stupid lol^^
the vbios patch before / after the settings?
it doesnt matter when you do the bios flash. if the settings doesnt work for you, mod them a bit.
after bios moding and flashing it back to the GPU , start with standard settings 1100 or 1150 core clock, insert 850 mv core voltage, and memory controller voltage 800, memory clock 2000.
after getting it work stable for 1 min, increase the memory to 2050 , wait a bit , check how it reflects the mhs. if its all stable increase to 2100, and check again, if it crashes, reduce to 2070.after finding stable stop, if you want you can increase core clock from 1150 to 1160, 1170, if it crashes you will need to add more voltage to the core so increase core voltage to 860. if it crashes increase a bit more.
its all about finding the sweet spot. which from card to card may vary.

Hello Rkulov,
You seem to know what’s up.
My 570’s keep crashing every time I attempt to put in numbers to get me to 31+ mega hash. Any advice? If so it would be greatly appreciated.
cheers
Cant see the full picture, post the OC settings.
The whole pic is above sir
hmm very strange why they are not working, but you have to improve your OC settings.
make all cards 1150 core clock and remove the DPM state.
then make them with 850 core voltage, 800 memory controller voltage and restart the rig.
Add amdmemtweak --REF 30 and Aggressive undervolting ON.
let me know how they work.
I will try it. Which one is the DPM state? And I just zero it out to get rid of it right sir?
yes. the core state is the DPM state. 0 or remove the digit.
what two cards?
hi i can help you for overclock .
the Hynix MJR and RX570/580 can run stable 33/34mhs
MJR ram voltge 900 and speed 2300 @ core 1287 on 900 mv ( runs on xfx with 72w gpu power )
its a XTX rx580 same as RX470/480
my nitro rx580x have XTR and uses lot of power on same settings 92w.
my 2250 strap drom Hynix MJR on polaris20 XTX 
777000000000000022BB9C00B5E67C49C0551015BF8E360C006686000C081420EA8900AB030000001A163745C3313F1A
my 2000 trap from Micron @ Sapphire Ntro+ SE
777000000000000022AA1C0073626C41B0591016BACDC6090060060004061420EA8940AA030000001914292EAE2E3B16
this straps lower the voltage and wattage.
micron runs core 1287@893mv mem 2300@937mv and I/O mem-contr @950mv @ 91 watt with this strap
Hynix run core 1287@900mv mem 2300@937mv and I/O mem-contr 950mv @ 72 watt with this strap.
you can test this strap on hynix, its stable to 2300 mhz, al straps from PBE have here generated fault on hardware in teamredminer, this strap not, its bit slower than the PBE only it makes more Bandwith.
Ps: the XFX with hynix ram can run 2300mhz hynix on 900mv i/o memcontroler voltge with this strap
also i run on B mode with ETH, the Dac Uses the full mem
