Have you tried catalyst? It should let you go down to 150 on mem.

The network tries to produce one block per 10 minutes. It does this by automatically adjusting how difficult it is to produce blocks.

I had the same problem with memclock, I was able to set it down to something like coreclock-125. The difference may have been greater than 125, I might be confusing that with 69xx.
I fixed it by running the latest beta version of Afterburner, going into the saved profiles (ini file) for my card, and setting the default/profile memclocks to 300,000. With that, Afterburner lets me select memclocks from 150-300MHz. "Reset" still brings the card back to 1375 on the mem, despite what I have set in the profile.
There's something wrong with the newest version of Afterburner. I could not change it after updating either. 2.2.0 Beta 10 will let you change it. |

How did you manage to downclock your memory to 150MHz? With Sapphire TriXX or MSI Afterburner I can only go down to as low as 685MHz. |

With trixx, lower the mem to lowest setting, click apply then it should move so you can lower it again. Keeep doing this until you get to 300/150. Alot of cards crash at 150, some do at 300  |

- with Trixx I can downclock memory, but voltage only down to 1170mV
- with Afterburner I can only downclock memory to 685, not lower - but voltage to as low as I want.
Real question is: How to downclock memory AND set voltage to 865mV ?

Use both programs and hope they play nice together. |

Trixx has registry entries for storing it's values. Manually setting them in the registry to what you want will "unlock" a range in the GUI that wasn't previously available.
Search the registry for ID_OC_MEM_SLIDER, ID_OC_VOLTAGE_SLIDER, and you will see these are set to the saved values in Trixx. Close Trixx, change the OC_MEM_SLIDER reg_dword to 150 decimal, and restart Trixx. You can now use a lower range of settings. Repeat for anything else you want to change.

No matter what I set for ID_OC_VOLTAGE_SLIDER, it always shows 1170 as the minimum. |

Why would the card crash? Odd... Easy to do.. Get MSI AB Beta 10. Set mem to min, apply.. close, open, set to min again, apply, close, repeat again... |

Not working for me. I can't go lower than 685. I now use cgminer to set voltage, gpu & memory clocks. Stop it. And then start DiabloMiner. That works. But I don't like it ... |

I usually set the memory in catalyst first for one card, then load Afterburner and apply it to all the others. In catalyst you can clock the memory to 150mhz for the primary card. Then in AB adjust the fan or something else on the same card and hit apply. It should set the ram speed on any additional cards you have as long as the checkbox is checked.

I just released cgminer 2.2.4 which is the first release with respectable (read not the fastest, but good) performance for 7970.

Thanks ckolivas. Which command line settings to use for optimum 7970 performance? |

Thanks. From the comments in his post it looks like ArtForz had to change the code itself to get it to work. But the changes haven't been sent to the vanitygen git repository (repository hasn't been changed in 6 months), so it looks like I'm going to have to break out the compiler and code editor again. |
