Has anyone gotten decent hashrates with a 5970?
The highest multiple I can set thread-concurrency is 1600. With intensity 11, I get about 130kh/s per gpu. At intensities 12 and over, the best I can get is 250kh/s from each gpu on the first card the both gpus on the second 5970 get "SICK".
How are you guys able to use such high thread-concurrency settings?

I've updated the target difficulty testing in the git tree. I'm reasonably sure it wasn't working properly before.
ozcoin is working fine, the most problems are with p2pool which reports something like 20hashes/sec.
But also on coinotron (was working fine before they changes something), 3.6 kh. I Tried ltcmine too which seems to report 27kh instead of 240
trying ltc.kattare.com right now..
seems fine, using it now since ozcoin already seems actively hopped
I have 20shares/minutes with them if that helps anything. I would really prefer p2pool though with all the ddosing going on.

There seems to be a problem with pools on higher share difficulty. cgminer reports the hashrate fine but what gets recognized by the pool is not. Neither invalids or stales are detected they seem just to disappear in a black hole. 
I can't tell if I am the only one having this problem or if it is just cgminer - reaper doesn't really work for me, it always tries to use my cpu as well.
What higher difficulty pool is that? On ozcoin difficulty is set to 20 and shares are returned fine and the pool reports the same hashrate. There is a change I do need to make to share difficulty checking as this code is as yet still incomplete so it's entirely possible you have just the right combination of difficulty and pool. I can't tell if I am the only one having this problem or if it is just cgminer - reaper doesn't really work for me, it always tries to use my cpu as well.

Okay I've thought about it some more and I think the best way forwards is to do away with the --lookup-gap and --thread-concurrency options and just get the user to input the shader count of their device and let cgminer choose. This will always set lookup gap to 2 and set the thread concurrency to the highest it can be that is a multiple of the shader count which would be much easier for users to configure. This then leaves you with the choice of gpu threads and intensity still. Otherwise there is far too much to configure, and most people won't be able to figure out how to do it. I plan to include a readme with the shader count of the various hardware like in that earlier post. What do people think of this?
Eg for a 6850 and 5770:
cgminer --shaders 960,800
Eg for a 6850 and 5770:
cgminer --shaders 960,800
Could you set those as the defaults and have the options to change them via command line or in the .conf file.
802 Khash/s. Two 5850's.
Image link broken. On 5850s you should try a multiple of 1440. So try 7200.Code:
cgminer --scrypt -o http://server -u username -p password --worksize 256 --lookup-gap 2 --thread-concurrency 5600 -g 1 --intensity 18
Same results.
Image link should work. But here is main. https://www.dropbox.com/s/b2hrkwrz688a5ta/Untitled.jpg

I'm receiving reports that cgminer doesn't work fine with Coinotron. I checked it out myself and indeed there seems to be some kind of incompatibility. I'm wondering what could be source of the issue. Does cgminer support getworks with lower than base share targets ? Does it support LP messages from different port than mining port?
Yes and yes. 802 Khash/s. Two 5850's.

Why?
What do you mean? I'm mining right now.
See it says 6800 not what 68x0 ? Same with 5700, not what 57x0. It mattters.

I'll take all your litecoins if you, uh, don't want them.
