Thanks
That and one other simple mistake of being in the wrong directory earlier fixed it all. Now it is mining away. Since I'm currently mining on only one card it displays as #1. Does it automatically pickup the other cards, or do I need to start a new terminal for each card. How would I differentiate them?
It automatically picks up all cards. |

anyone else notice the plastic sheeting all around the stock heatsinks that is slowly melting and looks like maybe just MAYBE it was supposed to be taken off before they put the heatsink onto the gpu board?
These diamond cards we definitely just fucking whacked together in some factory and thrown out there for sale. I highly doubt there is any need for plastic sheeting to be adhering to the heatsink all around the thermal pads and copper heatsink plates. What purpose could it possibly serve? Except to protect the heatsink in transport before it was supposed to be secured to the GPU board.
I wish I knew how to post pictures on this board to show everyone.
Huh, I've never seen sheeting like that on any card I own. Goddamnit Diamond. |

.\DiabloMiner-Windows.exe -u poolusername -p poolpassword -o http:api.bitcoin.cz -r 8332
Is one of my / or . or \ wrong?
Windows cmd.exe is a little weird, just type the name normally, DiabloMiner-Windows.exe, no ./. |

Troubleshoot this. I downloaded the newest version and can't get it working.
I created a bitcoin.conf file with
rpcuser=username
rpcpassword=1234
I tried clicking on the DiabloMiner-Windows.exe but it comes up with an error and immediately closes the terminal.
I opened the terminal and typed:
./DiabloMiner-Windows.exe -u username -p 1234 -o http:api.bitcoin.cz -r 8332
I have also tried taking off the leading . and changing / to \
Any suggestions.
--Windows 7 Pro, x64, one ATI 5770
Uh, what? If you're local mining, which is implied by your use of a bitcoin.conf file, you just do -u username -p 1234 -o localhost -r 8332 If you're actually intended on mining with slush's pool, -u and -p is set to whatever the pool tells you to use and then -o api.bitcoin.cz -r 8332 |

I can connect to mmpool's 80 port with simillar url,
another pool I failed connect to is eligius,
I also tried 8337 port, did't work
Not all pools support mining on port 80. Use the port the pool specifically says to use. |

That'd be depressing if all I can get is another 2%.
Yeah, it kinda takes the fun out of optimizing if all you can get is 2%. Any idea if there's a GCN feature that we can exploit for more performance like fixed function hardware or new instructions/amd-specific extensions? I initially thought that using size 16 vectors would help, thinking that the GCN SIMD cores were akin to x64 SIMD registers, but it seems that the card exploits its SIMD cores by running a scalar instruction on 16 threads at once. I'm trying to get the damned Kernel Analyzer to work in either Win in VM or in Wine, both is a no go, has to have a real running copy of the drivers, and the native Linux version locks up soon as DM calls an a CL function.
Don't even bother until the release a new version because Kernel Analyzer won't even correctly list the kernel stats for tahiti. Running the profiler via command line does give some useful output however, and I have .il, .cl, .isa and a comma separated value file of a profile run with -v 1 from my 7970 if you're interested. I'm more interested in it for generic 2.6 optimization. I'm hoping I can get 2.6 running as fast as 2.5 on my 5850 and _IF_ I can get it running as fast as 2.1, I can abandon 2.1 support (but I don't see how 2.6 could get that fast) |

Curious about how much room for optimization there is, I made some calculations to see how close Diablominer is to the maximum theoretical performance of the 7970 ( see here) and unless I'm missing something in my assumptions I found it to already be within ~2% of the maximum theoretical performance. That'd be depressing if all I can get is another 2%. I'm trying to get the damned Kernel Analyzer to work in either Win in VM or in Wine, both is a no go, has to have a real running copy of the drivers, and the native Linux version locks up soon as DM calls an a CL function.

Although, ~575 mhash out of the box on a 7970 is very inspiring.
Did you get your shiny new 7970 yet DiabloD3? Been a bit busy with RL, at least the money has finally arrived from Dwolla (seriously, 5 days? wtf) |

Excellent work on the early GCN support!
Is that your effort or someone else's? I need to know where to send the donation.
Mine, the support merely makes it work, it doesn't provide any useful optimization yet. Although, ~575 mhash out of the box on a 7970 is very inspiring. |

Update: Improved P2Pool support
Update: Update to lwjgl 2.8.2, jackson 1.9.2, commons-codec 1.6

Someone with a 7970, please measure the exact length of the card. My Gigabyte Super-5850 is on a 5870 carrier and just BARELY fits, it rubs against the ass end of the harddrives. I wanna make sure a 7970 will actually fit.

imagine if all pci-e slots are being utilized. 1 board with 5 slots = 35 cards max.
hahahaha, crazy.
Driver limit of 8 GPUs..... I don't know whether anyone has been successful at getting VT-d to work with more than 8 GPUs in a virtualized environment. I really wish it were easy to do. LukeJr has, uses KVM on a known-to-work VT-d board. Host gets a few, guest VM gets a few. The limitation is purely of the driver, AMD could fix it to do 16 or whatever. Yes but he has only tested it with one video card, and it keeps crashing. Ahh, he failed to mention that. |

Woah, and I said its probably possible for >600 on stock clocks. So close. |

-v 1 is what I am using witht he rest stock parameters. You should get ~550mh/s at stock speeds, ~650mh/s overclocked to 1125. You can undervolt these cards quite a bit if you are looking to draw less power. I have mine set to 899mV @ 925/500. I think I can shave off another 10-20mV with further testing. @1125mhz you can go down to around 1050mV.
Thanks, will try that... btw, I have been running the miner at 1125MHz clocks and so far, I've gotten 1 "hw error" over the course of a couple hours. Not too sure how concerned I should be about this, would it mean my overclock is possibly unstable? EDIT: seems it is due to the OC, had to back down to 1060 MHz to get fully stable at stock clocks. 1 hw error is basically meaningless. All cards, even at stock clocks, will generate them now and then. |

Pardon my newbie question (I did search).
How do I enable my second Radeon HD6950? I am running DiabloMiner fine with Cayman (#1) running at 312 MHash, but I can clearly tell the second card is not running at all as it is cold.
Linux x64.
Thats not strictly a DiabloMiner question. To mine with multiple cards under any miner under Linux, you must turn off Crossfire. Merely unplugging the bridge does not disable it, you must, as root, run aticonfig --initial -f --adapter=all and then restart X.This will disable Crossfire and make every card individually addressable by all applications. |

How are fans dying from heavy use an indication of manufacturer quality?
Sapphire is like the grand daddy of all of the AMD card makers. They sell the most AMD cards in the entire world and have been making cards since the dawn of AMD time. They also have an R&D role with AMD so their knowledge is second to none. That doesn't mean they don't have defects, but my research indicates they are every bit a top tier manufacturer.
Sapphire also produces the AMD branded FirePro cards, and they also produce every 5970/6990/7990 no matter which manuf actually sells it. |

HD7970, 2.6SDK, latest drivers... doesn't work:
I'm at a loss here.
I don't use Windows, but try to make it spit out a Java stack trace. I suspect its a driver bug. It is especially weird it crashes before it actually does anything. |

Never mind the miner screenshot, i'm more interested in the PCI-E splitter they used! What IS that abomination? ... I want one! Thats the product page for that thing. It even seems to have two pci-e 6 pin plugs for powering the extra slots for larger cards. |
