All ok now with the manual entry for device  Thanks! |

lol yeah the name isnt very smart and easy xD Please, try to put a OSD or something with info about overall mhash! |

Nice work.. I like that you input the device manually now, I even started to write my own front end based on your ideas, but now the new version supports all the GPU's I will be using this until I get motivated again to continue with my own front end ( http://i52.tinypic.com/29viti.png) gets temps and phoenix output plus detects all GPU's, I love the inbuilt overclocking great work and thanks for the fast fix... Im happy like Departure  BTW nice front end, hope you soon get motivated |

I think is a dummy plug problem... picture of resistors would be cool.

Is an OpenCL problem! Cant fix it but Im using AOCLBF with phoenix and is ok... anyways when I use both cores (As I said Im using only one card right now 6990) gpu usage goes like 60% in both cores is weird... using one core give 99%
Edit:
FINALLY FIXED !! Special thanks to "Departure" !!

an option to see overall mhash/sec would be really great!

Latest driver from AMD.com and the latest AMD APP SDK, latest guiminer, latest gpu-z, latest afterburner.
Will show some screenshots soon!
...and you can't mine with a single 6990 core (i.e. any one of the four cores)? Also are you attempting solo mining or pooled? Right now Im just trying to get one 6990 to work properly (just one card in the mobo) and I can see just one core in guiminer if CrossfireX option es disabled in CCC, and I can mine ok but as i said just one core... If I enable CrossfireX option in CCC, I see both cores in guiminer but one core work ok and the second give "Verification failed, check hardware!" error. Also in AfterBurner I see just one core with the right info, and the other core appears like no info... core speed, etc. |

You can't run more than 4 GPU's in windows as the drivers wont allow it, if you run windows then remove the 6950 or use a linux distro...
I ran 6 GPUs with 11.6 on Windows 7 64-bit this week and it works fine, AMD support also confirmed that 11.6 raised the limit to 8. My biggest problem was that the GUI overclock tools don't seem to be built around supporting that many GPUs, they would run fine but I could not overclock things using the popular tools. Did you use AfterBurner ? how many cores can you control with it? |

Im doing test with just one 6990 and nothing more and is all screwed... without activating the CrossfireX mode in Catalyst Guiminer only shows one device and is just one core because 330 mhash/s
If I active the CrossfireX mode in Catalyst I see 2 devices in Guiminer (both cores) but after few seconds mining one device shows "Verification failed, check hardware!" erros like crazy!
any help please?!
This *sounds* like a driver problem. It's windows so the amount of low-level troubleshooting one can do is limited. Clean install is an option. If Linux is an option for you. There's plenty of experience on this board. I'm running the same 6990 using Gentoo (but I think most people here use Ubuntu). I'm even running it in parallel with a GTX480 without too much trouble. Tried first with windows 7 x64, then format and clean install with windows xp x32 and the same results... linux isnt an option right now  |

I have problems with just ONE card in the system... |

Maybe one of the 6990's is bad. Did you try the other card (alone)? Is the OC switch off (position 2)? Are both PCI-e power cables connected to the card? Try running one card alone in a different PCI-e slot.
What is the brand and model of your motherboard?
What is the brand and model of your PSU?
Tried all the above mentioned before, switch OC is off, both cables connected, tried 2 PSU together, etc. MOBO is DFI Lanparty LT x48 PSU is CoolerMaster Silent Pro 1200W Gold The results are the same with both cards... dont think both cards are bad... maybe but really?... |

Thats is what I think too, but dont really sure...

Will try without the 6950 right now. BTW what about the crossfire ticket in Catalyst software? with it in OFF the 4 cores of 6990s dont appear in guiminer |
