Cant get the right hashed and driver keeps crashing!!!
If someone have the right setting file for the multipool, please share

Try this one:
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
.\sgminer\sgminer.exe -k x11mod -o stratum+tcp://stratum.cryptotrain.net:4444 -u your wallet -p x -I 17 --gpu-engine 1000 --gpu-memclock 1400
If this works you can add another parameters such as thread-concurrency and tune intensity and gpu-engine.
Use ltcrabbit mode and 13.12 driversHe Primano think you nailed him!!! do you know the Mh\s what you will need to get on X11 on a 290 card!?
Can i sue your utc adress on the forum then i desposit the UTC!!
Just as others said if this config works you can try higher gpu-engine and memory clock (increments of 25 MHz) until you get HW errors. You may add thread-concurrency 30464 and play with it and see if it helps if not remove it. Generally 3.3 MHs is quite ok IMO, maybe you can reach 3.5. Also you can try to undervolt your card, but be careful!
