ok now, after a lot of work, her are my stats

166 mh/s
940 Watt at the wall
-100 mv core voltage
+25% PowerLimit
1120 mhz CoreClock
1910 mhz Mem Clock

any feedback it is ok or have anybody a other better way to make the stats better?

You have to install msi afterburner and manipulate clocks and voltage there , not in the Polaris editor!

Perfect! Did i need a special version of MSI Afterburner or onle the newest one from the MSI page?

it's ok

I have 6x Asus 470 8gb micron , moded the bios and put 1625 strap and then clocked ddr to 1950 and gpu to 1140 , up the TDP 25% and they make 27mgh. The problem is that if i put a monitor to any card wich is 1950 and hashing for hours with no problem and no errors in Hwinfo and stop the miner the pc crashes! I thought that one card is poor , but changing others and put the monitor to them they start to do the same, is there a way to fix this!
And don't believe that they burn 100watt, 6 cards burn 1200watt dualmining and 1000w only eth! It is very disappointing !

You can get a bit under 1000w dualmining 6gpu if you undervolt enough
I don`t know how much to undervolt , i undervolted it to 940mv and still the system burned 1150 watt, this -40mv in msu afterburner! Using btc pro and celeron and 2 psu corsair cx750 !
Anyone can help with the problem after stoping the miner?

i'am noob with mining but usually undervolt guides say to do -100mv

Hi,

i think the 1625 strap is clear, i must copy the dato to the other up fields.

but clock ddr to 1950 is not clear for me, what i have to do, which field do you men?
and up the TDP by 25% is the TDP 85 plus 25% = new number for TDP 126, right?

and a other question, where can i underclock to reduce the power at wall, some peaple speak from 28-30 mh/s with under 100 watt...

Regards
Willi

guys what method you use for fast test your gpus stability oc/undervolt? one program for see errors or something?

At least 24-48h mining to see if it's stable.. an hour test will give you a hint of stability but has occasionally not been enough

thanks, i will have a look in the other forum.

i have a backup from my firmware and if i open the file with the polaris editor, it look not goot, i have no right values in mh/z

Hello,

i found a tutorial --> http://1stminingrig.com/sapphire-nitro-rx-470-8gb-oc-bios-flash-mod-tutorial-hynix-samsung/
But my card has no Bios switch. is the switch on each sapphire-nitro-rx-470-8gb-oc card?
Any tips for my card modell to be save to brick my card. in kind of a problem i have no revovery solution whitout the bios switch


UPDATE:
i see in gpu-z my card has MICRON Memory, is that possible to mod the card? at the moment i get 24 mh/s

Best regards
Willi

Hey it is possible to mod with micron but I know less about micron than the other mem types.. copying the 1500 mem strap may work.. there may be some other forum topics regarding flashing gpus with micron memory. maybe here too: https://forum.ethereum.org/categories/mining

Hello everybody,

Sorry for the stupid question, but the post is very long.
Is there a link in the 33 pages where it is described how to install the mod graphics bios mod or change the settings with which tools?

I bought yesterday 6 graphics cards and will read the faq's before the cards are here :-)

6x SAPPHIRE Radeon RX 470 Nitro 8GB OC (11256-17-20G)

What values can I expect at ETH Mining, at which power consumption

Greetings from Germany

guys the crash with grey screen what depend too high mem freq or too much undervolt?
i'am trying the oc my hynix 470 card on -90mv 1050 gpu clock and 2000 mem freq, +20% power limit.
the system crash with grey screen every time i open a browser or anything  Huh

black screen -> core
purple screen (or artifacts) -> mem

my crash are all grey screen or empty desktop background color  Huh

Fail to plan, and you plan to fail.

my friend can rach 30mhs with super low power arround 40watt (GPU z)
use 2100mhz mem clock, but my gpu fail to reach it, anyone know why my gpu fail and his gpu cxan reach 2100 ? (same hynix)

2100mhz is impossible at 40W. Not hard or difficult, impossible. The lowest you can get on GPUZ for 2100 would be 80W.

Now, every card is different, if you get lucky you get a good piece of silicon that can touch 2100mhz. If you are unlucky, it may not cross 1900.

Mem clock has little (not nothing, but little) to do with overall wattage. You're looking at core - which is responsible for most of your draw.

Interesting. Some tests are in order then I suppose to see if we can get to a GPUZ reading of 40W, at any clocks. Will report back soon.
