hi all, sry if the question has been discussed but i have no time for reading 600 pages.
I am desperate, been tried everything but cant get the damn ultracoinminer to work at -I 12 without lots of errors...
I have a gigabyte R9 270, windows 8.1 x64 - 4GB ram, catalyst 13.12 and driver version n. 13.251.0.0 of 06.12.2013
My kh/s is only 45, and I am playing with settings since one week and cannot do anything better... I must setup intensity 10!!!!! to avoid HW errors and finally the pool recognizes my work but at a very low speed, about 18/19 kh.
My settings are:
setx GPU_MAX_ALLOC_PERCENT 200
setx GPU_USE_SYNC_OBJECTS 1
ultracoinminer -o stratum+tcp://ultra2.nitro.org:4337 -u xxx -p xxx --scrypt-jane --sj-nfmin 4 --sj-nfmax 30 --sj-time 1388361600 --thread-concurrency 8192 -I 12 -g 2 -w 256 --gpu-powertune 20 --gpu-memclock 1250 --gpu-engine 1040 --temp-target 70 --auto-fan --gpu-fan 35-85 --temp-cutoff 84 --temp-overheat 79 --gpu-threads 2 -Q 0 -s 1 -E 10 --lookup-gap 3
I changed TC to everything from 6400 to 24000... lookup gap from 0 to 3, gpu-powertune from -20 to 20... NOTHING changed. I am just frustrated.
You obviously didn't try everything.... You can't get the best hashrate using that miner, but this should avoid HW errors using ultracoinminer
ultracoinminer --scrypt-jane --worksize 128 -g 1 --lookup-gap 3 --thread-concurrency 52736 -I 12 -o stratum+tcp://<pool address>:<port> -u <username> -p <password> --sj-nfmin 4 --sj-nfmax 30 --sj-time 1388361600
If you can't enque a scrypt buffer that high (since you only have 4 GB system memory), try
ultracoinminer --scrypt-jane --worksize 128 -g 2 --lookup-gap 3 --thread-concurrency 26368 -I 11 -o stratum+tcp://<pool address>:<port> -u <username> -p <password> --sj-nfmin 4 --sj-nfmax 30 --sj-time 1388361600
you didn't say whether your card had 1 GB or 2GB - the above is assuming it's a 2GB card. If it's a 1GB card, well.... it won't be pretty, but you can try this anyway
ultracoinminer --scrypt-jane --worksize 128 -g 1 --lookup-gap 7 --thread-concurrency 45184 -I 12 -o stratum+tcp://<pool address>:<port> -u <username> -p <password> --sj-nfmin 4 --sj-nfmax 30 --sj-time 1388361600
