Anyone using cgminer on a 6770, 5830, or 6950 have any recommended settings? My friend wants to mine and we got about 150kh/s from his 6770, 228kh/s from the 5830, and 356kh/s from the 6950. But I'm wondering if any more is possible.
I know there is room for improvement for the 5830.

I have some 6570 recommended settings that's all I tested out last night , testing 1 card at a time AMD Radeon HD 6570 Recommended Settings: --scrypt --worksize 256 --lookup-gap 2 --thread-concurrency 4096 -g 2 -I 17

Am I misunderstanding, I thought it was supposed to select the best values? It selected 8192 for both of them.
Yeah, I'll stick with my settings that are supposed to produce invalids but aren't. My 6850 runs at 6144 and I can take it up 15+ in intensity. My 5770 running at 3584 and I push intensity 18 on it without any invalids.
No it wont pick the best. Read again. It will pick the largest. Then find the multiple of your shaders less than or equal to that and YOU set that manually. That's why I put that list of shader counts below...

And those actually pull better numbers. Now I can give my friend (and anyone else) better number to try too. Awesome.

I guess I can put in a database into the software to lookup the best values after querying the device... maybe soon.

There might not be enough info in opencl to do this from cgminer. What does cgminer.exe -n report on these cards?

Why? What do you mean? I'm mining right now. I mean so that cgminer could detect the best settings automatically. See it says 6800 not what 68x0 ? Same with 5700, not what 57x0. It mattters.

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

Image link broken. On 5850s you should try a multiple of 1440. So try 7200.

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.

Could you set those as the defaults and have the options to change them via command line or in the .conf file.
