I cant get the miner working with my 2 x Windforce 280x. Running Catalyst 13.11.

Heres my config:

set GPU_MAX_ALLOC_PERCENT 100
set GPU_USE_SYNC_OBJECTS 1
ultracoinminer -o stratum+tcp://utc.greekpool.eu:3337 -u myusername -p mypw --scrypt-jane  --sj-nfmin 4 --sj-nfmax 30 --sj-time 1388361600 --expiry 1 --queue 0 --scan-time 1 --intensity 10 --gpu-engine 1050 --worksize 256 -g 2 --thread-concurrency 8192

Its hashing fine but there are no WU produced.

Anyone have a solution?
