Hello . hoping that someone with 6870 gpus or some knowhow can help me out.
I just started mining LTC but im getting less share per minute then with BTC mining. im getting few HW on one of the cards. alot of both if i change thread concurrency

color 02
cgminer --scrypt -o http://stratum.give-me-ltc.com:3334 -u xxxx -p xxxx --shaders 1120 --thread-concurrency 4800 --gpu-engine 900 --gpu-memclock 1000 -I 13 -g 1 -w 64 --temp-cutoff 95

xfire 6870 6850
win 7 64
latest drivers
latest sdk
works perfectly fine with btc

Im not sure what the thread concurrency should be at but 4800 gives me best results so far
