Try to reflash your custom bios on those faulty cards via command line if you decrease intensity and you still get hangs .
Worked for me on a 480.

I have a computer with several graphs and wanted to assign for example, 2 to one coin, 2 to another and 2 to another, to simplify, with claymore I know how to do it, is to add a line in the start.bat (-di) and the number of the graph you want to work and ready, just use the ones you order... But with CCminer and SGminer, would anyone know how to do it? or the command to use, greetings and thanks!  sgminer --help  |

Phil.... run ccminer/cryptonight instead -- I think NH pays higher rates now vs equihash. use the skunk build v2.2 crytonight even lower power and less heat are bonus Did you move your amd farm to monero? If so, which miner are you using if I may ask. I'm getting over 800h/s per card with sgminer-gm. http://imgur.com/a/i2JmUThings are even better pool side. What cards and core/ram settings if you don't mind sharing? My modded 470/480s and 570s do only 650-750 with Claymore and 1500 modded bios. Modded 460 around 400, unmodded 460 around 350. 470 & 480 with Samsung memory. Custom 1750 straps for eth. Stock core, memclock between 2100 - 2200. Undervolted. I had just switched from eth to see what speeds I'm getting and then just let it be. Try with sgminer-gm. I get between 720-710h/s for a rx580 4gb with core 1150 and memclock 1975. I had to lower the memclock because the gpu crashed all the time. Is the rig stable with memclock 2100-2200? You do get very good hashrate about 800h/s for rx470 480. Wish I would get 800h/s .. I don't think is is necessary to clock the memory that high for cryptonight anyway. How high you can go depends a lot on chip quality. I'm using the unofficial beta dag fix drivers right now and eth clocks so can't really adjust many things. I will revert to 16.11.5 and fine tune things shortly. ETH wise you do need high mclocks and/or tuned custom straps to get the best hash. One of my 470's is stable at 31.9mh/s 1206/2200 -126mv. I modified the vbios by myself using this thread https://bitcointalk.org/index.php?topic=1758267.0 It's really a gold mine if you are able to follow the info from there (do it yourself instead of paying for it). Perhaps this is also why I'm getting better speed with xmr. |

how much power do you use?
64 - 70W with spikes up to 85 in gpu-z. Undervolted -126mv. I set clocks for best performance as I pay close to nothing for power (but I'm limited to powering only 6 cards for now). |

@cvsea,
Use sgminer-gm v5.5.5-NH, I use smOS
3500h/s = 6 x RX 470-4GB Gigabyte G1
1230/core and 1650/mem (cranked up the core, but lower the memory clocks)
Note: these cards are BIOS-modded for ETH mining.
I'm using the 5.5.5 version (not NH), getting 3300h/s from 4 cards (also modded for eth) - sapphires 8gb - high mclock up to 2200. 24h effective hashrate on nanopool is 3500h/s. Tried zawawa too but it screwed up the driver. Hope profitability stays up as I will have to keep mining it until payout...being a small miner sucks sometimes. |

Thanks Might have something to do with gpu-platform. Set it to 0 if onboard graphics is disabled. |

You are asking to much.  This is obviously not only for me but for the community as well. Perhaps doktor83 can make something of it...the tool is there. Who shall be the first to crack the mighty Pascal!?  Anyway, thanks for having a look. LOL, duh, why do you think he's not gonna say shit. My owner may begin selling Nvidia ROM work, though. 'nuff said. Do you know if that link actually works? She was the one who posted it. |

I may have found a way to sign the rom.
But I can't find the location of the straps + there is the problem of fixing the checksum.
I think you need to find and parse three tables in case of nvidia: 'memory type' table which lists memory types supported by bios, 'timings' table which lists all timings without memory clocks and memory type and 'map' table which maps memory clocks+memory type to 'timing' id. 'timings' table starts at offset 0x2e40a from bios start, 'timings' are '0c1910048902312411040588ec180022328061d3e270b2a60b86000200bc34000039020a06000000a65514040a01f06c1333330300000000000000000a00008000000000'

Clock ranges (not sure which multiplier should be used) used are: 0-540, 541-1299, 1300-2800, 2801-3300, 3301-3700, 3701-4500. Timing ids for different memoty types are (ordered by clock): type0 - 0,1,2,3,4,5, type1 - 16,6,7,8,9,10, type2/3 - 0,1,1,2,3,none. Type 0 is Samsung GDDR5, type 1,2,3 is Micron GDDR5. Ok...this is clearly above my knowledge. How would you go about optimizing the straps? I might be wrong, but we could use this https://gfs.nvidia.com/ to get the modded rom signed. |

Do you, by any chance, know how to read a 1070 bios? I'm interested in finding where the memory straps are located in hex.
I don't; my owner does - not likely to get that info. You owner has been very generous so far... Damn shame, you could have made a killing modding pascal. |

Have a look at this https://bitcointalk.org/index.php?topic=1433925.msg20491019#msg20491019So there has been an unofficial beta driver around for a few days. I also saw another user claiming he was testing it. I'm still skeptical a little bit but my hashrate is exactly the same as before and effective hashrate is better than ever. Unless this robinhood is some sort of evil genius with nothing better to do I would say the driver is legit. |

If you have Sapphire, use Trixx to undervolt. It will show 0 for cclock and memclock but you can control undervolting and fans.
Been running this driver for almost 2 days. Most stable/accurate effective hashrate I've had since starting to mine.
If ethermine would stop having problems it would be even better.
What version of trixx? I instaled i think 5.0 and when run it a see that it dont show cclock and memclock soci turned it off.. also what i noticed when i run trixx is that program itself run very slow almost not realomding... but probably problem in version.. It works like this: http://imgur.com/a/vagYUAll info is there |

There's definitely something wrong with your setup. You should be getting about 24 at stock. EDIT: or maybe 22 since they are 4gb
I really do not think so, I have 6 Asus Rog Rx 470 4G hynix, 1 Gygabyte Rx 470 4Gb gaming 1 hynix, and 2 XFX Rx 470 4Gb samsung dual BIOS. Except for the XFX (Which seemed to be already overclocked), all of them hits 20 at stock, I tried claymore 9.5, 9.7 and windows and linux. Overclocked all cards gets 24,5 in windows (linux stays 20) This is what a 470 can do. http://imgur.com/a/8ajS4You can say there's nothing wrong when you achieve this. Can you share your mod? My HIS rx470 (Hynix) can only reach 21 MH/s (stock), 22.x (modded) & 23.x (DAG fix). Thank you. Mine are Sapphire with Samsung. They key is custom memory straps. There's a thread here about it: https://bitcointalk.org/index.php?topic=1758267.0Once you give that a read you should be able to do it yourself. Also I found that -asm 2 helps a lot with the 470's |

Finally decided not to wait for the official release anymore and try this out. I'm surprised to say that no other driver until now was as efficient as this one. Hashrates are back to what they used to be + effective hashrate is above reported. Hope it's not just luck, only been running for a few hours. No problems at install apart from a code 43 error easily fixed with the pixelpatcher. I have Sapphires. Using -mclock and Trixx for undervolt and fan curve. So far so good... I have a rig with 6 Asus Rx470 4Gb, and my hashrate was unaltered for the DAG epoch, every card is doing ~24,5mh sinces June which I started. How can I see the modifications?
Have you modded the bios of your cards? With modded bios and before the decrease in hashrate, modded cards were doing 29+ MH/s. I modded bios, on June, they mine ~20mh/s stock, with modded bios they mine ~24,5 and they continue at that value. How can I get 29? There's definitely something wrong with your setup. You should be getting about 24 at stock. EDIT: or maybe 22 since they are 4gb |
