wow, anything over 80 and I get very nervous. I start downclocking and downvolting to get any card below 80C
Why? From everything I have read, mid-80's is fine for GPU's...... I will have to lower the ambient temp in the rooms and see if I can get it down that way. |

Still nothing... Whats that about, are wiretransfers going trough like TH claims they are or not?
I have had a Paxum withdrawal pending for 9 days. Still "in process". It pains me to say it, but I have lost some respect for the Tradehill crew. While I do not doubt their honesty (I have lost nothing), the communication with customers has been sorely lacking. This breads speculation, mistrust and fear. A deadly combination. Before this debacle, I was using TH exclusively for all of my trading.....now I have looked into other options and have moved all my business elsewhere. I hope they get it all figured out soon. I loved the simplicity and ease of use at TH, and am sad this had to happen. |

I'd be offering around $300 a piece, open to negotiation. I'm currently entertaining an offer for 4 diamond 5970's at $1150, shipped, but would like to see what others have to offer.
Jump at the 4 Diamonds. I would not sell for anything less that $350 a piece. In other venues they are going for closer to $400. |

I've got about $6,000 at my disposal and I'm trying to decide if I want to buy 8 more 7970's or buy the bitcoins outright.
That is a no brainer. Buy 20 used 5970 and get 40 GPUs. Lolz. As if you can even sniff a 5970 for $300. |

Can't remember who it was but some dude got them at around 720 or 700 mhash/s !
But then the power consumed makes your MH/W ratio suck !
1-upd! max @ stock V: 1070 core, 695Mh/s @ 1.20V: 1170, 759Mh/s and for shits and giggles... @ 1.25V: 1240 core, 805Mh/s Tip: try phoenix with -k poclbm AGGRESSION=10 WORKSIZE=256 Any advice on better setting with Diablo? |

Yup, confirmed it doesn't work with GUIMiner...
I'm getting 640 m/hash on 1075mhz... at 60c w/ fans at 70%, on stock voltage (diablominer).
I was running 1125 but it was just slightly unstable and I didn't feel like bumping up the voltage.
good god....at 70% they must be screaming like banshees. I can hardly stand them at 50%! |

They wont work with GUIminer.....but they absolutely rage with Diablo.
I am at 1.2 GH/s with 2 of them.....1000 Mhz core
Someone got them to 666mhash each  Can't remember who it was but some dude got them at around 720 or 700 mhash/s ! But then the power consumed makes your MH/W ratio suck ! Wow....I cannot wait to get some set-up at my "Free power" location. I will push them as far as I can. |

I am looking for a couple 5970's to build a new rig for my basement. Currently have a space heater down there that isn't hashing, so I figured I'd change that...  Going for 4x5970's on an MSI 890FXA-GD70 board, so please, reply/PM me if you have anything you are looking to sell! -Bees I may have a couple for you.....What price are you offering? |

Now that several of us have these cards hashing away, I thought it would be nice to start a thread dealing with the how to best mine with it.
I am running 2x 7970's currently, and will have 4 mining by the end of the day.
Tidbits of info:
-Will not work with GUIminer
-Works great with Diablo
-Runs stable even with massive overclock
I am getting just over 600 MH/s per card with core set @ 1050 MHz. Memory is underclocked to 600. I had it clocked at 1100 at one point, but the increased hashing rate did not seem to justify the power usage.
I am very ignorant on tweaking settings other than voltage and clocks, so I am hoping people smarter than me can add to this thread. Lets figure out how to optimize these bad boys!

got them to 1.3 GH/z @ 1075 core.
Not sure pushing them any further will be worth it.
Nice. I would wait to see how far others can push their cards before I pushed it too much further myself. I know beyond 100Mhz overclock i need to increase voltage or the system locks up. The stock clock speeds on my OC edition 6950 are 830 but I can get 947 stable through afterburner if I turn my memory speeds down. Lowering your memory speeds should lessen the thermal load on your GPU and drop your temps, increasing the lifespan. 1075 seems like it should definitely safe as long as your thermals stay low. I made a custom fan profile in afterburner to keep my card cool. ther are holding at 84 degrees.....seems pretty good to me. |

Here are some results so far on a dedicated miner:
ASRock 870 Extreme 3 R2.0
Athlon II X3 455
Two cores disabled
CPU voltage dropped by 0.1V
1 stick of DDR3 1066
Seasonic X-1250 PSU (80 Plus Gold)
Windows 7 64 bit
60GB Vertex 2 SSD
All of my dedicated miners are usually using a headless Ubuntu install on a flash drive, but since there probably aren't any programs for Linux that will allow me to change the clocks/voltage on these cards yet (besides what's allowed in aticonfig), I'm using Windows to test this.
2202 Mhash/sec @ 583 watts -- 3.77Mhash/watt (962 mV, 975Mhz/160Mhz)
2106 Mhash/sec @ 553 watts -- 3.80Mhash/watt (949 mV, 925Mhz/160Mhz)
2134 Mhash/sec @ 528 watts -- 4.04Mhash/watt (931 mV, 925Mhz/160Mhz) (one of my cards will not stay stable at this voltage though. The other 3 are solid.)
2060 Mhash/sec @ 498 watts -- 4.13Mhash/watt (918 mV, 900Mhz/160Mhz) (all cards stable)
If you still think these cards aren't efficient, you're drunk. If they were still using VLIW, they'd be insane at hashing. All GPUs show 99 percent utilization. If small improvements can be made to the miner kernels, efficiency will be further improved.
I've got a small external fan blowing on the rig (as with all of my mining rigs). The temps on these cards while mining at 2060 Mhash/sec are 63/64/65/61C. The fan speeds on auto are adjusting to 30/30/30/27% respectively.
All wattages were read with a Kill-a-watt (which makes the measurements on the AC side, of course).
Any idea how this compares on a mh/watt basis with 6970's? I am in the process of replacing a lot of 6970's, and would love to get an idea of how much more efficient these are. |

Is that per card or between 2?
If that is each then all I have to say is wow!
between 2. Now I am getting about 600 MH/s per card with core at 1000 |

DiabloMiner: DiabloMiner-Windows.exe -u example@example.com -p password -o pit.deepbit.net -r 8332 Phoenix miner: phoenix -u http://login@gmail.com:password@pit.deepbit.net:8332 -k poclbm DEVICE=0 VECTORS BFI_INT WORKSIZE=128 AGGRESSION=11 I would also suggest GUI Miner for windows machines.. WE HAVE A WINNER!!! Your first recommendation on Diablo did it. THESE THINGS FUUUCKING RAGE!!! over 1.1 GH/s before any sort of tweaking. AMAZING post your address and the coins are yours. THANKS ALL!! I think i should get some and feel very ripped off by that. You were clickign on the file and it was disappearing when you started this thread. I showed you that and he merely beat me to the syntax. Agreed. I will split it.....very fair point. Post your address as well. |

Purely out of simplicity you should probably try GUI miner and you can run the phoenix miner. I found the phatk kernel option to be the most efficient.
For a standalone miner I use the following flags: -k phatk poclbm VECTORS BFI_INT AGGRESSION=12 worksize=128 FASTLOOP=false
For mining in the background and still being able to watch movies and such I lower the aggression to 5.
FYI I am mining with a 6950.
I use GUI miner for everything.....but I just got the 7970's in the mail, and they wont run with GUIminer..... Sounds like you are going to be having some fun. I dont think you use the BFI_INT vectors for the 7xxx series there is a different vector protocol to use. If you are trying to run the latest phoneix miner it wont run under my Win7 64 bit either and it gives me code errors. I have to use the older one which is fine by me since i get a lot anyways. Any ideas on how the boys currently running the 7000 series are pulling it off? |
