Here’s my stats that give stable results for me. I’m using the 0000 straps from mineros
Straps im using for Samsung Memory

Obviously you will need to flash your bios but for those willing to i hope this helps.
Fans are set to 55% constant
hola, pudiste solucionarlo? tengo 2 afox y no pasan los 8mh
your cards are not bios modded correctly.
First of all , all samsung memory cards need to be bios modded with polaris bios editor 1.7.4.
thats because version 1.7.4 allows you to use the uber mix 3.2 timings which are better.
while modding hit no to ubermix 3.1 and then yes to ubermix 3.2.
then you start with the following settings :
Core clock 1150
Core voltage 850
Memory controller voltage 800
Memory clock 2100
Aggressive undervolting ON
amdmemtweak --Ref 20
Do not use DPM states, they dont work when you set core voltage and clocks. for these cards they are not good.
For the Hynix memory , you just bios mod it. then 1150 core clock , 850 core voltage , 800 memory controller and 2150 memory clock.
wow… your RX 580 4096 MB, can reach 61.28 how can?
It is mining ERG.
GPU9 is interesting 
hi
i have 6 Rx580 and 4 RX6800
i cant oc any of them
when i try error’s will comes up tell me gpu is dead or amd driver failed
how can i fix this and use they max hashrate?
what invalid shares (in front of gpus)(just rebooting 1min before of taking picture) mean?
I tried @dazeb 's settings with BIOS(uber-mix 3.2) flashed MSI Armor RX580 .
Core Clock: 1200
Core Voltage: 850
Memory Clock: 2200
amdmemtweak --REF 30
Result:
32.55 MH with 80 watt.
on 85 watt i have 34.20 MH with Sapphire Nitro+ SE
i have test this week whole range on Sapphire Rx580 with micron, and other tab the XFX Rx580 with hynix, both can run mem @ 2300
On top from screenshot you see 1200@825mv with 2200 mem@825mv with the memcontroler on 800mv and use 76 watts on the Sapphire nitro+ SE
the XFX uses 1200@850mv wth mem 2200@825mv and mem controler I/O on 800mv
Micron strap on 2000: 777000000000000022AA1C0073626C41B0591016BACDC6090060060004061420EA8940AA030000001914292EAE2E3B16
for max 2300 mhz ram clock ( here is polaris not stable on timings above 2100 mhz ram )
Sapphire uses Polaris 20 XTR and the XFX Polaris 20 XTX
XTR from sapphire is not efficient.
Is that sapphire setting or micron or hynix?!
Hi, i modded my bios manually… im using the teamredminer… with my bios mod i got this as best result:
I would upload the bios mod here but dont know how…
I may have missed it above, but what does --ref 20 (or ref 30) actually do?
Thanks!
Hi Phil, could you send me this BIOS? I have same card but I can’t get this results. =/
hi I have 6 asrock rx 580 and vbios by Polaris
whith this ox sitting and Hashrates Power sage is very high about 100 is that normal ?
the screenshot whs from saphire with Micron ram.
the sapphire with hynix ram is not so power hungry 
Rx 580 XFX XTX runs :
1150/0/800/800/2050/800 @ Ref 30
1150@800mv on XTX chip
2050@800 on Hynix GDDR5
mem I/O @800
Ethash 30,55@53W is efficientie of 57,64%
the second efficient is :
1150/0/800/800/2150/800
1150@800 on XTX chip
2150@800 on Hynix GDDR5
Mem I/O @ 800
Ethash 31.12@54w is efficientie from 57,63%
Saphire Nitro+ SE RX50 with XTR chip on Micron GDDR5
Efficientie not so good .
highest efficientie is
1175/0/806/800/2200/806
1175@806 on XTR chip
2200@806 Micron GDDR5
mem I/O@800
Ethash 31.9@72w is efficientie from 44.31%
the second is
1175/0/806/800/2150/806
1175@806 XTR chip with Micron GDDR5
2150@806 Gddr5 Micron
mem I/O@8000
Ethash 31,83@72w efficientie from 44.21%
1150@800 is less efficient 42% on sapphire XTR chips
