For all of you guys i made a custom bios from the one in the main post.
You won't need any wattool,wattman,afterbuner,trixx or any other software of that type, i set everything in the bios like Insider00 did with wattool, so :

Def gpu clock : 1144 Mhz
Def mem clock: 2150 Mhz

Mem straps 1625
VDDC (gpu voltage) set at 925mV
TDP 120w
Set fans to hold cards at about 70c, so you don't need fan regulation either

Before flashing remove ALL software that you used before for manipulating (wattool,wattman,afterbuner,trixx...).
Then clean all video drivers with DDU.
Flash bios.
Reboot, reinstall video drivers.

Test.

Guys i have 3 Asus rx470 8gb micron ddr. I ve read here that they can do 30mgh , but mine a very bad obviosly , cause with the original bios , mem of one can reach stable only 1730 , the other one 1900 and one 1850! Is there a way i can make them do better, how do you achieve clocks of 2050 ? May be they are crap after all! The code of memory is 6TA47 D9SXD 7438 , just to know is your code different?
I saw that your micron bios has 2 timings strap , but i have only one!

it's was for rx 480 8gb sapphire nitro micron

i run 29.5 with 470 4gb and 8gb

470 always with saphire micron memory ?
Cause i wanna build my rig with 8 gpu but with 480 require more power then my target it is 470/570 (PSU 1200watt) around 30mhs each gpu, i didn't bought before cause i was scared to hit micron shit then waste my money.
Do you have any info about power of 470 on your rig?

80-100w with modded bios and under voltage for rx 470 sapphire and msi armor, and about micron memory will be mostly for cards only Nitro not Nitro+

it's better to use Evga 1300w u can even use it for 7 gpu mining

Thanks soo much to insider who got me 28mhs on my micron mem sapphire rx 480s. its official now.... micron mem is not so shit after all
