In general the result in termes of hashes should be more or less equal. But for LTC it is kH/s instead of MH/s for BTC. Not sure but I think I read something about factor 0.9xx
according to the config you use the same settings for different cards, this might lead to the HW errors. Set the parameters for each card helps perhaps. Also for the finetuning. If your computer is dedicated to mining you can raise the Intensity to 16 or even more. Shaders setting is obsolete as long you are also using the thread-concurrency setting.
Also the thread-concurrency can lead to HW errors if it is set too low. Some said the tc should be a multiplier of the shaders, some say it should be a multiplier of 64. good is what gives best hashrate.

thank you very much. yes all you said is correct. found that info online and tried to apply it to my bat file. im using my pc everyday and need my first gpu to handle all my work without any lagg. after i found out how to apply different settings to my gpus HW were much more easy to get rid off. to find a good thread concurrency without HW i did 6144 - 64 - 64 - 64 untill i found a good spot.

This is how my bat file looks now :
color 02
cgminer --scrypt -o http://stratum.give-me-ltc.com:3334 -u xxxx -p xxxx --thread-concurrency 4352,5600 --auto-fan --temp-target 83,75 --auto-gpu --gpu-engine 800-900 -I 12,17 -g 1 -w 64 --temp-cutoff 91

With this i get :
6870 : 82c 2700rpm 246 khash 0 R 0 HW 2.3 shares per minute -i 12
6850 : 74c 2780rpm 259 khash 0 R 0 HW 2.5 shares per minute -i 17

i know i can press both cards a bit more etc but since i need some of the computing power and GF hates the fan noise this is the setting im okey with.

Ah yes, the WAF .... (WomanAcceptanceFactor)
Good that it works out for you, glad to read that. But I'm a bit curious about the temp of the 6870. I think 2700rpm is something like 30-40%. I can imagine you did chose the temp target to get the best solution in terms of noise. But perhaps there is something inside your rack to optimize airflow. Seems abit to high for me with intensity of 12.
