I just fired up my WDC wallet and instantly got 5 active connections and it synced (1000 blocks) with no issues. How can I help?

what is nibble's network hash rate anyways? I was gonna mine it once block rewards hit 32.

Ya anybody else having trouble you really need to play with your engine setting to find the magic number. Set your memory to 1500 and your engine to 1044....or if you want start engine at 1050. Then move it up or down one number at a time and try to find your sweet spot. ONE NUMBER can make a huge difference...for my card the engine speed at 1043 = 580kh...at 1044 = 720kh....then at 1046 = back down to 580kh.
I just want to reiterate what whitedragon said. Plus or minue one to core or mem clock can change my 7970 hash rate from 730+ kh to like 550 kh. And it's a cumbersome process, but it's also the best way to find your rig's sweet spot. |

damn, still no good for me.   did you try core clock at 1085? |

Here is something strange, I reset GPU back to stock settings 1000/1375 and tried these settings with no overclock
--thread-concurrency 8192 -w 256 -v 1 -g 2 -I 13
GPU 0 - 520kh
GPU 1 - 720KH
WTF?? any ideas
you reset the settings on only one gpu, maybe? hahahaha, your right, forgot I had to do the 2nd card on the drop down box... :-) at a certain point in all this I remember my brain just going...blehhhh. And I went to bed. lol |

Hmm i might try your fix with the 13.3Beta_3 drivers. I had given up trying to get my HIS ATI HD 7970 IceQ X² above 600kh/s. It seems to want to run at 550-580kh/s no matter what I try. Already attempted to flash numerous bios files with either no improvement or brick(and thank god the dual bios saved my ass a few times!).
Mate it looks like you have the EXACT same issues as me, amazing that 13.3beta worked Just one advise, do this: run amd_cleanup_util_1.2.1.0 utlity to remove all your drivers, reboot and then install new drivers Yep. This was my breakthrough as well when I was messing with my other rigs a few weeks ago. Drivesweeper and Atiman uninstaller, plus going into appdata and win32 and win SYSWOW64 folder and deleting all amd and ati folders/files. |

OK, so now GPU 0 is at 705kh but runs at 92 degrees, while GPU 1 runs at 720kh and only at 78 degree!!
Unfortunately those temps are the problem with this model gpu if not using riser/extenders in an open air case or on a rack. Whoever designed the vent flow should be freaking fired. I can keep all five of mine under 80 degrees, but they are elevated and well spaced out with a box fan on high. |

I had the exact same problem with the exact same cards....and none of the guides out there gave me anything more than 10kh difference. But...the settings that hope2907 gave you were what I was going to suggest as well...cuz when I finally found those settings posted somewhere I jumped up to about 725 per card. Mine are pretty much identical but I don't use temp-target....also I don't know if it is true or not but somebody on the boards here somewhere said that he didn't get any change in hashrate unless he put --thread-concurrency as the last setting. This is how one of my bat files looks, for scrypt mining (pool stuff removed) setx GPU_MAX_ALLOC_PERCENT 100 cgminer --scrypt --failover-only --intensity 13 -s 1 -g 2 --worksize 256 --auto-fan --gpu-engine 1044 --gpu-memclock 1500 --thread-concurrency 8192 These were the ONLY settings that made any difference at all to my hashrate. -auto-fan --temp-target 79 --gpu-engine 1044 --gpu-memclock 1500 --thread-concurrency 8192 -I 13 -g 2 -w 256
it should get you 730
And the Winnder is "WhiteDragon"" tried those exact same settings AGAIN but this time with 13.3Beta_3 drivers and BAMM 700-720kh WTF!!! Right on. Maybe it's the --failover-only arg that did it for you... |

I am using the latest cgminer (3.1.?) and I installed AMD SDK 2.8 separately. And I have 12 gb of RAM, corsair vengeance. It matters for scrypt...
Which reminds me, did you try mining a SHA coin, like BTC or TRC? Were you able to get over 700 mh? If so then it's clear mem clock speed is the issue.

I got these cards and I got 750+ kh on cgminer and oddly enough, 760+ kh on guiminer-scrypt. my settings are nothing fancy, but here's what I do:
I use Sapphire trixx to oc.
set core clock to 1085
mem clock to 1500
leave voltage alone at 1170
and command line arguments are:
--thread-concurrency 8192 -w 256 -v 1 -g 2 -I 13
make sure to use stock bios.
Note that I get 750+ kh with one or two gpu rig....as soon as I add a third, because of psu or mobo bandwidth (i really don't know), my hash rate drop to about 740 kh for each card....I have five running on one rig.
Also note, these cards get HOT. And that's because they vent hot air from the top and bottom and not through the sides. So if you have your gpus in a case (ie. not open air or on a rack/crate) your rates will suffer because of temps. Let me know how it goes.
I forgot to mention, I am runnin cata 13.1, AMD SDK 2.8, on Win8 64bit

Awesome, mate! Whatever you did worked. Thanks.
you welcome! providing the best support here  Indeed! |

Erun, under 'my workers' tab it shows a couple of my workers as not active but it is calculating hash rate for them. I restarted my miners and it seemed to work for all but one worker. It stills shows as not active but also a hash rate is calculated. Could you confirm whether I am getting shares or do I need to restart my miners again and hope it works?
Erun, nevermind. I restarted my miners again and it seems okay. ah. okay, glad to hear you're good now  It's doing it again  I will pm username. okay I've made a small change to the code, lets see if it does the trick. try looking at your worker stats after 10 minutes from now. Awesome, mate! Whatever you did worked. Thanks. |

i am sorry about web interface hang. will get it back shortly!
this is going to get fixed in few minutes. miners should be still running smooth! should be fixed now! please check Everything is looking good. My miners were fine even when front end went down. Great work! |

My initial reaction after reading the info released: "what a waste of a cool name for a coin"

profitability is the name of the game.. risk to reward ratio.. here since it is done backwards as to rewards its best to mine it backwards get in late +1 |
