i have 6 rx 480 running with modded bios at 770 hash average per card , and i use around 800Watt
is this ok? or can we use even less power ?
looks good i did 6x 470 758hash/card for 750W Are you all wanne make me criing :-(((( Is nobody willing to help me with my AMD Radeon RX470 Nitro 4GB OC.. I triied everything..Flashing, Wattman, Sapphire Trixx.. Doesn´t matteer what i do, it is always getting worster, then better. I getting 640 Hash per card and one of these cards seems to be anpthe model. Looking a little bit different. Power Supply is on the Top, not on the back and she has other RAM, not Samsung ans is 1236 - 1750 takted. And she is slower. only 580 Hash. Is there something i can do? RFegards, Scandalrosi |

According to NIST and ECRYPT II, the cryptographic algorithms used in
Bitcoin are expected to be strong until at least 2030. (After that, it
will not be too difficult to transition to different algorithms.)

RFegards,

Rule 1 : Do not flash a BIOS that someone uploaded because more than likely it will not be for your exact card, and it will make things worse not better. So use PBE to mod memory straps on your own bios. Rule 2 : Do not hardcode clocks into the card untill you have tested the card thoroughly with regular OC to figure out what clocks are stable on it. Rule 3 : Stability is far more important than peak performance, go for the settings that get you 48+ hours stable over peak perf settings. Rule 4 : There's a gazillion guides with detail step by step tutorials on how to overclock your card, please search for them before blaming the community, this isnt school, you do not get individual attention anymore. |

I don´t really understand what is going on right know, but OK..
1. I did.. Saved my old bios, modified it as dicriped. Restore it to BIOS. And the card wan´t identified from system anymore. Then i restored the old Bios and all is ok.
2. Why do you think i have done that?
3.That is exactly what i wanne to do.
4. I´ve seen tons of tutorials, how to modify th rx 470. But most of them, all show just to modify 1750 1900 2000 row. And that is the onlny thing i have done, with polaris.
But doesn´t matter. The speed is enough for me and i got the power usage down..Thats OK..
Hmmm, now i´m a little bit in panik, to ask my question:-(
I´ve gotten my 5th RX470 today. I have 2 X 750CM+80 Corsair. OS can´t install the driver for the 5. card. doesn´t matter wich one it is.
Is there might be a limitation in Window 7 proff.? All Cards are working fine, as long as they are not the last one, installed.
I´m sorry if this is a school question again. It is not my opinion to get any special attention. I´ve read most of this thread and there are a lot of qustions regarding the rx470..I´m sorry for my last post. That was not, to get anybody in stress to help me, really..
Regards,
Scandalrosi

1) Asrock H81M is a miniATX board, and has only two PCIe slots, so no, that is not the board that you are using. What you have could be the Asrock H81 ProBTC or Asrock H81 ProBTC V2 2) Those arent 5V plugs, they are molex power plugs which can draw upto 12V. And you should not have them plugged in when using RX 470/480 cards. 3) Again, go through the forum threads, every answer you need already exists there. Please have the patience to read through hundreds of pages and try 10's of settings, we all did it. |

looks good i did 6x 470 around 758hash/card for 750W Which timings do u use? I use 1750. What memory and GPU clock , voltage ?  i posted couple page back, 1425 was the best for me, hynix memory on sapphire rx470 4G memory runs at 1920 gpu at 1200 default voltage i don't care much about power usage i just limited a bit because my psu is 750w and i sow it was a bit over 750 in corsair link |

I´m doing nothing else, then reading. I´m sick at home and i´ve a lot of time.But i also have a lot of qustions.. But you gave me hope, that there is a solution for my issue:-) Regards, Rosi |

RFegards, Scandalrosi average of 750 Hash / GPU, 100W power usage / GPU (on the wall) + 50W for the system. All cards are sapphire nitro 470 (with differents memory). Using -a 2 parameter, it helps for power consumption. @Scandalrosi : Don't use other BIOS. I provided you already informations about the best way to mod your bios which is to paste your original BIOS' 1500 timings (elpida, hynix) into 1625, 1750 and 2000 straps. It is very easy to do and should provide a nice increase already. If you just flash BIOS' that are not compatible with your GPU, chances are high that it won't work. |

I am using ethOS but Windows 10 works as good without problems |

The H81 ProBTC I remember had issues with 6 cards, but the V2 fiexs that problem. You do not need the molex connectors on the board at all, unless using unpowered Risers and non RX 470/480 cards. both of which no newbie ever uses. |

Hi together,
i tried both. With both Molex connected and without. Result was the same. I bought a new H81 Board.. There must be something
wrong with the other. And i can´t find anything regarding to this issue in the net.
Thats so sick. I have installed them one by one. OS is identifiing each card. Then plugg in the 5. and the error message appaers. Driver could not installed. Then i unplugg one of the 4 others and reboot, and the os is finding the card and can install the driver. When i then re-plugg in the other one again, that worked before, i got the same error for this card. Driver installation failed. I can do that with any of the 5 cards. All are working fine. As long they are only 4.
I´ll see, when the new board has arrived.
Regards,
Scandalrosi

OOK.. I got it.. What a nightmare. Just to let you know. From Version 13.12 on AMD has changed some entrys in their driver, related to the registry. The result of this change is in some Asrock H81 BTC Pro R2.0 and Asrock H81 BTC Pro, it is not possible run more then 4, or 5 GPUs. There is a verry good, working fix available. Here is a good tutorial and all you need to fix it. https://lbr.id.lv/coin/6xgpu/13-12_mod-v3_README.htmlRegards, Scandalrosi |

They could have switched to a serial power design...last time i talked to them their first batch of miners were parallel based design (ie about 4-5 chips per DC-DC power buck) in order to reduce time to market, and they were going to switch to serial later on(string of chips running off 12v like bitmain). If they did that in their new batch they could possibly gain 10-15% in power efficiency.
