Thank you for this advice. Flashed the 570 now to uber mix 3.2 and getting 31.5 mh with the changes you suggested. I wanted to know what the difference between uber mix timings were and how do I know which ones to use? I have all the cards running on ubermix 3.1. Do I just flash all on ubermix 3.2 or is there a specific reason to use one over the other?
Hi guys, I am completely new in mining… I have 570 8gb Sapphire with Samsung memory - I have (hopefully) flashed the BIOS, running ove 30Mhs but the watts consumption is around 100 w. My stable setting is like on the picture. Do you have any advice what to do? Thanks in advance…
these uber mixes are for samsung memory. Uber mix 3.1 is more demanding. thats why on samsung memory ending in FB i am using 3.2 which is better for this kind of memory. with ubermix 3.1 you cant go over 2090 memory clock, with 3.2 2150.

here is what you can do.
set all core clocks 1150 , then remove the DPM states ( core states and memory states ).
Then put all core voltages to 850 and memory controller voltages to 800. test if you can run the cards with 2090 or 2100 memory clock.
if they are all working correctly after these settings. you can try to lower the core voltage by 5 every step until some gpu crashes and then you increase it 5 and check again if its stable.
Hi @rkulov First of all thank you for all the help you provide. I have a rx 570 xfx rig and after working for about 2 or three days, different gpu starts to give invalid share until there comes a time when I have to restart. Any recommendation. I have all the gpu with mod bios.
very strange. you settings are kinda passive. i mean you can up a bit the core clocks to atleast 1150. if you want to keep them i think you can run with 850 core voltage on the cards. Why dont you sent also memory controller voltage to 800.
try with higher memory clocks.
you can try also with lowering the core voltages.
Dears can anyone help me to understand how to reduce temp & power utilization of my RX580 Samsung memory without loosing much hashrate.
Note: i am already using Polaris undervolting tweaker under advance config.
amdmemtweak --REF 30
Hi, thanks for directing me to the way… but I am not sure I got the point of ubermix - it is a programme or just a “formula”? is there any… ehm manual for dummies? Thanks…
I didn’t understood well. What should I do? I already tried different clocks, but system is unstable. I modded BIOS with one click Polaris 3 program.
anyone have settings for a msi rx580 8gb gaming edition (red accents on card)?
Hello everyone.
I have Asrock RX570 8G phantom, with 3 memory types: samsung, hynix, micron (reported by PolarisBiosEditor).
Using hiveos undervolt, I can acquire 31.x MH hashrate, but can’t reduce the wattage. The best I can get is 107w, while I saw many ones in this thread can down to 80w with 31~32Mh hashrate.
Tried many undervolt profile and applied one-click bios patch of PolarisBiosEditor too, still no help.
The card doesnt have 3 types of memory. I supports 3 types but it has only one which is Micron.
if you have bios mod the card correctly you can try with memory clock 2100-2150.
Also memory controller voltage should be 800 and remove the memory voltage because it doesnt work for these cards.
switch on Aggressive undervolting.
If all stable, next step is to try lowering a bit the core voltage.
vddci 800, with high core its like “normal” to have high temp´s and wattage with some cards…tho others may run way lower wattage with same settings…
Could be that chip thermal paste is dryed so might help if u re-apply paste, that´s what i should do to several of my 5xx gpu´s…it only take like 15min per gpu…lazy me!
Hi all,
Try these settings for Hynix memory cards. They are modded with Polaris Bios Editor.
They are good for Micron rams as well. First 3 cards are Aorus and the rest are plain Gigabyte 
One thing I would like to meantion is that most people use Ref-30 MemTweak for all cards. Thats not right to do.
Ref-30 is for Hynix and Micron cards.
You shall use Ref-20 for Samsung and Elpida. It really matters a lot.

I get with the Rx580 35 mh/s @ 93 Watt ( DPM and MDPM works in PhoenixMiner )
Core: 1290Mhz 887mv
Mem: 2300Mhz 937mv
VDDCI @950 ( Mem to Polaris20 i/o voltage and also youre mem voltage )
Bios is Modded to max 107A en 110W max bios settings are 1366 core and 2300 mem, and other timings
I think after reading this forum it’s not bad
