any test in scrypt mining?
Yes, Im all into scrypt now days....But I cant seem to get a good hash rate, I was expecting same as 7970 as they are pretty much the same cards. But I only get 585 khash and the temp is waaay too high with 91c. |

Do you have a 16x PCIE extender or something to hang it in the air? A picture or 2 would be great. |

As this card is connected to my office-pc, it is inside a closed case...thats probably why it is heating up so much. I also get artifacts on the screen so I dont think this is healty for the card?  |

No extra options tho
Nice  If you have time can you test it on litecoin or any other Scrypt base coin? I want to see how many Kh/s it gives. Also please try to post watt usage  Hi, I have been testing different settings for scrypt and I think im doing something wrong with the settings. Atm I only get avg 585 khash with these settings: , "intensity" : "13", "vectors" : "1", "worksize" : "256", "kernel" : "scrypt", "lookup-gap" : "0", "thread-concurrency" : "8192", "shaders" : "2048", "gpu-engine" : "1110", "gpu-fan" : "10-90", "gpu-memclock" : "1605", "gpu-memdiff" : "0", "gpu-powertune" : "0", "gpu-vddc" : "0.000", "temp-cutoff" : "95", "temp-overheat" : "86", "temp-target" : "76", "api-port" : "4028", "expiry" : "120", "gpu-dyninterval" : "7", "gpu-platform" : "0", "gpu-threads" : "1", "log" : "5", "no-pool-disable" : true, "queue" : "1", "scan-time" : "120", "scrypt" : true, "temp-hysteresis" : "3", "shares" : "0", If anyone has a clue what to change for more khash please say so  I have tried higher Tc with lg 1-2 but that doesnt work at all. [/quote Try "gpu-threads" : "2". You can try other settings of my 7970: "lookup-gap" : "2", "thread-concurrency" : "8192", "gpu-engine" : "1080", "gpu-memclock" : "1500", "auto-fan" : true, |

At 91C for graphic card, your motherboard, processor and everything else ganna be close to 70C. |

But I only get 585 khash and the temp is waaay too high with 91c. I was expecting a lot more kh/s  Anyways try increasing the Intensity to 15 & thread-concurrency too & see if the kh/s increases. Also the main reason of high temp is your cabinet. I guess it doesn't have enough ventilation. |

You need some fan to exhaust the heat out and some holes to let the cool air go in.
Shouldn't cost you a lot..

Set "thread-concurrency" to 24000 or so. See https://litecoin.info/Mining_hardware_comparison and look at the parameters used to take 7970's to higher hash rates. You should get 700+ Kh/s out of your card. |

Thanks for the info, looks like the hash is almost the same as HD 7970. Have to wait for R9 290X now.. few more days |

In term of thread count and other settings. Because you should be getting 630 at stock clock and about 750 overclocked. Too bad I don't have one and I can't really test it myself. |

I use the exact same settings on my sapphire 7970, with exception of not setting shaders but thread concurrency to 8192 and it works 760khash. Clock is set to 1080/1500 1,13v, 80 C in a computer case, not open air.

I did everything I could do, researched a whole lot and even helped others achieve good results with their gpus over at overclock.net but couldn't get my gpu to mine properly. I never had an issue with my former 6950, nor my 7950. (which wasn't the best miner but still pulled over 600kh/s without so much hassle) Trying to figure out what card to get next, I'll probably order next month. |

Hi there, after a weekend full of testing.. all I can get is 605khash with my R9 280X with 1080/1500 settings...tried a lot of things, but most settings get a HUGE amount of HW errors.

There is something wrong here as you should be getting much more. I get 650-700 from 7950s.. Yup I figured as much..but I Dont know what. Using higher TC makes cgminer crash on start, same with using lookup-gap, tried clocking some, that got me 20-30 higher khash but crashed the card efter 15 mins |
