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

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

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

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

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

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?

It is perfect! You are lucky with your micron cards! Mine don`t want to undervolt that much! Is this dual mining or only eth?

Hello To all, I have a question regarding the hashrate of the card Asus Radeon STRIX-RX470-O4G-GAMING 4Gb mining monero . I use Claymore and my max H/s is 540 actually but when I look at Benchmarks on http://monerobechmarks.byethost5.com/ I see that most of the people are getting up to 740H/s on monero with similar card. I did make a lot of research on google and several sites but no way to get more details about how to get this H/s . In the past I did mine dogecoin with radeon card and I remember that it was possible to use different settings in the bat file that could serioulsy raise the H/s . But I have no idea how to do that with Claymore and I did not find any example settings to try. Could any one help me out ? Thank you leole

When the AMD 500 series came out, I bought up a number of 470 8g cards in desperation. Most of my experience has been with Sapphire nitro+ rx 470 8g cards, and in my haste I bought a number of Sapphire nitro rx 470 8g {not the + version} and so far I have come to the conclusion that they suck ass. I can't seem to mod the bios without them not responding, and almost any moves I make with voltages makes them unstable. I have read this whole forum and saw that others have had these same issues, but I didn't find any clear success stories either. There was a lot of talk mid to late last year about these cards, so I am hoping someone has figured out a way to get these cards up to 27-28 MH/s with a wattage lower than what I am getting at 24 MH/s. Any real life solutions are appreciated. I simply want them stable and using less power at an average hash rate. I am not looking for miracles, but perhaps a bit of hope would be nice. I have spent hours and hours trying to get these cards to a better level of performance to no avail. I appreciate any consideration.

I did follow the instruction on this site http://cryptoyeti.com/rx470-bios-mod/ . Very easy but the problem is that when done the original drivers do no longer detect the card  So I can not use it anymore and need to load back original drivers.

How many do you have? 18, and I still can't seem to get a good set up for them. The most I can get is 24 mh/s per card with 6 cards pulling 1000W, but I really want 27-28 mh/s like the nitro+ cards if possible. Any thoughts?
