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

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.

Enjoy

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!

I am newbie mining.....can you please confirm the method for installing this bios? I got 6 Sapphire Nitro(non plus) RX 480 8GB .....every card gives 23.5 Mh/s using minergate......I really want to get more juice from these cards

BTW.....thanks Insider00 and Doktor83

[Marvell1]

No, it 's a obvious sign of too much OC.
Hynix won't be stable over 1950 MHz with the common timkng straps.
Even with custom straps you are lucky if you can go over 2000 Mhz.
1950Mhz with 1500 timing should bring you about 28 mh/s.

yeah my hynix 480 and 470 cards i just used 1900-1925 some even as low as 1850 just to keep them stable

my feeling is 1 or 2mhs more hash is not worth me rebooting a rgig once everyday

[GPUM1ner]

Thanks doktor83!

Your rom allowed 4x Sapphire Nitro 480 8GB reach 29.3MH/s (Micron).

I tweaked the settings a bit, but I mostly needed the straps as PBE wouldn't work.

1100 GPU/1000 mV
2050 Memory/1000 mV

Fan minimum 50% makes them run smooth.

I can't confirm his rom is best, but at least the straps are changed. What strap mod did you perform?
