Tried out Rjb82's settings with 13.1 drivers on ubuntu linux 12.10, doing 1100eng/1500mem/20intensity, working well at 648 Kh/s on SAPPHIRE Vapor-X 100352VXSR cards.
Not to hot except for one which has riser cables in the way in my rat's nest ghetto milk crate build.
Thanks Rjb!

If anyone's on linux, here's some settings that worked well for me:
(warning, unix nerdery below)

1. create a bash script , i.e. run_cgminer.sh

#!/usr/bin/env bash
export DISPLAY=:0
export GPU_MAX_ALLOC_PERCENT=100
export GPU_USE_SYNC_OBJECTS=1
export GPU_MAX_HEAP_SIZE=100
cgminer --scrypt -c $1 ${@:2}

2. I then put the config details into a JSON-formatted .conf file, such as:

{
"gpu-engine" : "1100",
"gpu-memclock" : "1500",
"intensity" : "20",
"thread_concurrency" : "16384",
"vectors" : "1",
"worksize" : "256",
"lookup-gap" : "2",
"temp-target" : "70",
"auto-fan" : true,
"scrypt" : true,
"pools" : [
   { "url" : "stratum+tcp://luserpool.com:3333",
     "user" : "LTC4CO2",
     "pass" : "LTC4CO2"
   }
]
}

3. then I call run_cgminer.sh (don't forget to make it executable with %chmod +x run_cgminer.sh) with the .conf file as an argument, and any arguments I want to add:

%run_cgminer.sh somefile.conf [ extra arguments ]

4. actually it's nice to use a program like 'screen' to keep your terminal session alive even if you log out / get disconnected. Screen is like a terminal server
a - ssh in
b: %screen -R -D cgminer_session
c: start cgminer script
d: detach from cgminer session with ctrl-A, d
later on ssh in again, re-attach to cgminer session with %screen -R -D cgminer_session

5. getting cgminer to start automatically on boot is left as an exercise for the reader. Note, you must have an X session running.

6. bonus points for automatically rebooting when GPUs lock up.

Johnny5, I'm running:
Ubuntu 12.10 (kernel 3.5)
13.1 drivers
cgminer 2.11.4

I'm currently getting 620 Kh/s, standard voltage. 1050eng/1500mem/19intensity.
currently trying the settings shown in the images above (1110eng/1500mem), getting about 650, watching stability.

Also curious to see how 12.8 or 12.10 drivers do.

Card(s): SAPPHIRE Vapor-X 100352VXSR Radeon HD 7950 3GB
Algo / Coin: Scrypt / LTC
Miner: Cgminer 2.11.4
Script/Config:
export DISPLAY=:0
export GPU_MAX_ALLOC_PERCENT=100
export GPU_USE_SYNC_OBJECTS=1
export GPU_MAX_HEAP_SIZE=100
cgminer -I 19 -c easy1.conf
easy1.conf:
{
"gpu-engine" : "1050",
"gpu-memclock" : "1500",
"thread_concurrency" : "22336",
"vectors" : "1",
"worksize" : "256",
"lookup-gap" : "2",
"temp-target" : "70",
"auto-fan" : true,
"scrypt" : true
}

Results: 618,618,615 Kh/s
Comments: Ubuntu 12.10 using Catalyst 13.1 - comes with APP SDK2.8, ADL SDK 5.0.
Machine is headless, I use ssh or x11vnc to connect. Cards are in a milk-crate case, so heat is not a problem - fans run at about 50%. Haven't fully tweaked things - at least one card crashed at gpu-memclock 1500. Currently trying to figure out under-volting. System power consumption with dual-core FM2 athlon, ssd, is 750W

I had similar problems with Ubuntu 12.10 (quantal), but it worked with:

sudo apt-get install libminiupnpc-dev libminiupnpc8


which installed all the necessary header/library files.
The versions for narwhal will probably be different -
You can:
apt-cache search libminiupnpc

to find them.

And another post... looking forward to being released.

Looks like they had trouble implementing VARDIFF (dynamic difficulty adjustment), and they have since rolled that change back. I've been back on them for about 8 hours, so far it's looking very nice, their reported KHash rate matches very closely with what cgminer reports. Knock on wood!

Hi --

New to mining BTC and LTC, currently running 1xHD7950, and building a 3xHD7950 rig - although I'm late to the party, this should be fun, and I will probably eventually make some money on top of the capital invested (300USD for 1xHD750, 1400USD for 3xHD7950 dedicated rig).

I've been mining litecoins as they are a bit more favorable at the moment, and have mostly used wemineltc.com (and ltcmine.ru). All in all, they've both been quite good with a slight preference for wemineltc. For the last 3 hours none of the shares that cgminer has reported have shown up on their server - turns out I am not the only one, see recent posts on https://bitcointalk.org/index.php?topic=169249.220  .
At least other people have the problem, at first I was worried I had some malware that redirected shares to a dark pool (which would be a clever feat!). Currently back on ltcmine.ru, I'll see what happens. I suspect and hope they just have some bugs on their server, as they mentioned something about stats being off. We'll see what happens - if this is:

a) a bug with stats reporting, but the shares are recorded and will be properly credited to the account
b) a bug where shares are not being properly recorded on their end - that will be interesting to resolve
c) they are burning their clients - not likely, but who knows

Cheers!
(I was going to post this in the linked post, and then realized I am still in the newbie forum)

Hi --

Late to the party, mining a little with a 6850. Thinking about getting into litecoins.
