those are the different power levels for the gpu. so the lowest is for 2D mode when you're no utilizing the GPU, the higher ones are for more demanding application calls.
What power usage per card do u have at 740 hash? |

What power usage per card do u have at 740 hash? Should be Sub 100W / card at these voltages. |

What power usage per card do u have at 740 hash? I am at around 360W with 3 cards (RX480) and sys power. 410W Including CPU Mining (i7 4790K). |

They are better for tweaking yes? Good cooling... With these I safely get 740 hash and sub 800 w in total yes? |

Yes. They are good cards, with the best (lenient) mosfets and good cooling. They didnt go cheap like Gigabyte or Powercolor. But remember you may still need to tweak you bios / strap timings to run it efficiently. |

But remember you may still need to tweak you bios / strap timings to run it efficiently. Yeah was not sure to get the cheaper 4giga ones but I am convinced buying the 4giga nitro are the best way to go. I will reflash the BIOS with the 1500 straps and undervolt... |

Can someone please help?why is this happening randomly ? before this it was rock stable for >24 hours 11:55:18:642 e74 Round 11:55:20:064 948 GPU 0: HashCnt = 1024, time = 1395 ms, hashrate = 734 h/s 11:55:20:080 948 Round 11:55:20:892 55c GPU0 t=49C fan=46%, GPU1 t=55C fan=41% 11:55:20:892 55c watchdog - thread 0, hb time 812 11:55:20:892 55c watchdog - thread 1, hb time 2250 11:55:20:892 55c watchdog - thread 2, hb time 80437 11:55:20:892 55c WATCHDOG: Thread 2 hangs in OpenCL call, you need to restart miner

11:55:22:174 55c Restarting OK, exit...and when it restart minner PC just hangs and I need to manually restart PC. It's not problem when I'm here but I soon plan to move miner in other place where I will have much cheaper electricity but I will have no access to minner and this will be a huge problem for me. 2x480 8gb OC ~ 1470 h/s with 305 W from wall 1350 MHz, 1080 mV 2200 MHz, 1000 mV reject rate about 1.3%, suprnova pool

Is there a difference between gigabyte rx480 8g gaming en the saphire Rx 480 nitro 8g? |

We need a new XMR miner! Adjusted to the 4XX cards and the new AMD drivers.
@Claymore... please?

Maybe, but in my 480 rigs mining XMR with wolf's miner is still more profitable than any alternative |

Depending on your electricity cost and willingness to run second coin along ETH, but XMR currently gives few % better profits. I used to mine ETH+DCR and ETH+SIA but that is long gone. Now the choice is between ZEC vs XMR and the latest is clearly a better choice  |

hi i received an rx480 sapphire nitro 4G but does not look good  it s slower than my 470's 4g and it use lot more power i notice it has Hynix memory, looks not great the 470's have elpida what i was able to mod easily get some more than 700mh with the 470 1220gpu 1920memory rx480 original bios it run at 1320/1950 get 600mh only, can slow down the gpu to 1270 for same speed i used polaris bios editor for the rx480 but cannot see the memory frequencies so i tested all the 6 last timing, the slowest one was working but speed not great and the 5 last timing they all crash i gonna test 1 or 2 slower but i guess it s not gonna be great i ve got the rx480 cheaper but same price than the 470 but if it s slower it s not great  |

Why is that? For those who pay electricity, it's just not profitable. Even with the recent small recovery on both DCR and SIA prices... |

2x480 8gb OC ~ 1470 h/s with 305 W from wall
1350 MHz, 1080 mV
2200 MHz, 1000 mV
reject rate about 1.3%, suprnova pool
use "-r 1" and reboot.bat with shutdown /r /t 5 /f - problem solved (better yet fix your card settings) thank you for solution with reboot.bat  which settings I should use with my cards? This gave me most hashes but apparently is randomly unstable |
