Is there a way to use optimal settings for both VLIW and GCN without running two instances of DiabloMiner?
I've had to flash every 6000/7000 card to drop the memory clock by a significant amount and to drop the voltage at all (in Linux).
Would you please share the knowledge how to flash (or modify the bios of) 7000 cards? 
Gotta say Diablo, your miner kinda rocks. Thanks so much for making it available for everyone! 
It can set the memory clock to whatever your GPU's firmware is limited to, this is usually far below the minimum displayed in CCC.
It can set the voltage on any card that uses stock VRMs.
The 6000 and 7000 series cards have always been limited to 125Mhz below engine clock (IIRC, my 7000's went 150Mhz below engine clock). I've had to flash every 6000/7000 card to drop the memory clock by a significant amount and to drop the voltage at all (in Linux). It's been about 4 months since I've tried AMDOverdriveCtrl though. Apparently I need to give it another go? I have 84 video cards with modified BIOSes. It'd be a godsend to be able to hit low memory clocks and adjust voltages without flashing cards anymore.It can set the voltage on any card that uses stock VRMs.
The 5000's are a different story... a reference board will clock to just about whatever engine/memory/voltage is entered.
Yes, as long as you've modified the firmwares, you're fine.

Use Debian unstable, use whatever is packaged newest by Debian (do NOT use the .run installer provided by AMD), and use AMDOverdriveCtrl to control clocks and voltage.
Correct me if I'm wrong, but AMDOverdriveCtrl cannot change the voltage or lower the memory clock substantially (unless it's been updated since I last used it).It can set the memory clock to whatever your GPU's firmware is limited to, this is usually far below the minimum displayed in CCC.

Until now I have found no way to set GPU clock, mem clock and voltage at the same time.
clocktweak can do that, if you don't want to switch to linux as advised above.

I have a host with 6970 and 7970.
Until now I have found no way to set GPU clock, mem clock and voltage at the same time.
- MSI Afterburner: I can set GPU clock and voltage, but mem clock can go no lower than 685
- Sapphire Trixx: GPU and mem clock can be set, but voltage is fixed
- ATI tray tools won't run with the 7970.

Use Linux.
Hmm ... I never thought about mining using Linux. Because of all the driver madness that I was reading the last couple of years.
- which Catalyst would you suggest for Linux?
- which tool would you recommend to set GPU & mem clocks and voltage?

So I downloaded the latest version of hte miner and extracted it.
Do I need to do any setup in order ot use it? I keep trying to use the DiabloMiner-Windows application and all it does is open, then instantly close some command line text. How do I stop it from doing this>? (Windows 7 as the OS btw).

Its a command line application. Either run it from the command line, or run it from a .bat file that has the args you want.
I gotchya. Thanks for hte clarification. Got it wokring now.
This might be a stupid quesiton, but the mhash number shows two numbers. What is the difference between the first and 2nd number?
15 second average, forever average

Systems at home are still on 12.1, sometime in the next 8-12 hours I'll have a chance to update them and report on the changes.
Oddly enough, my home system seems to have lost a few mhash going from 12.1 to 12.2, at least based on my initial tests.
When I arrived home, I was getting 560mhash. 2 5830s, so 280mhash each. 880 core 300 mem.
After uninstalling 12.1, installing 12.2, several reboots, I am getting 553mhash, 7 less. Same core and mem speeds. 276~ mhash each at 880 core doesn't seem far out of line, but it's puzzling to me why it would go down at all.
With core clocks increased to 900 mhz, I am getting 565mhash, but then we aren't looking at an apples to apples comparison.
The home system is on windows 7 64, while the work system showing the improvment was on windows 7 32.
I'm going to have to do some further testing and figure out what is going on, it's entirely possible I made an error somewhere.
So are we still running no flags for the best performance on GCN with the current DM?
Oh, and 2 BTC sent to help fund further GCN development.

Yes, just make sure you're using 12.2.
C:\Bitcoin\DiabloMiner>DiabloMiner-Windows.exe -u myuser -p mypassword -o http://api2.bitcoin.cz -r 8332
Just get rid of the http:// and you should be all set.
THANKS! Can't believe it was something so simple
Sorry again for the noob post!
I seem to be getting slightly less MH/s than I did with Phoenix 2, although that was with fine tuned paramaters, whears I am passing Diablo no parameters besides my pool. Great MH/s for auto detect settings! Will try and tweak it and see what I can get from Capeverde 7770!
Make sure you're using 12.2. DiabloMiner doesn't autodetect, the default merely happens to work best on GCN. However, no one has tried all options on 7770s yet, -v 2 and -v 4 and -v 2,1 (and 3, and 2,2 and 1,1,1 and 1,1,1,1 and so forth...) probably will be slower for you, but you're welcome to try.
Also, do not use -na, 12.2 fixed this.

What Mhash are you getting and what core/mem speeds?
