no one knows why I can't mine?
post your current config settings and your rig details
My pc:
AMD FX 8320
G.Skill 2x4GB RAM DDR3 1866mhz
Shappire Radeon HD 7950
The config:
ultracoinminer -o stratum+tcp://ultra.nitro.org:4337 -u x.x -p x --scrypt-jane --sj-nfmin 4 --sj-nfmax 30 --sj-time 1388361600 -w 256 -g 2 -I 12 --thread-concurrency 16384 --no-submit-stale --expiry 10 --scan-time 1 --queue 0

Ok Albert, first your config is for nitro.org pool but you are looking on nitro2.org pool. for results. Completely different pools.
First shut your rig down, by that I mean kill the power completely and wait a bit before restarting. The drivers need a reset.
Is your dual bios switch on the card on (lit up blue) or off (no light). The blue light needs to be on for those config settings to work. Also add some parameters for that card. --gpu-engine 1040, --gpu-memclock 1250 is enough. Also set a --gpu-temp about 72. If this does not get you hashing near 100kh/s then add look up gap 3 and should give you about 70kh/s
Same problem...
Actually he is connected to nitro2 the URL does not make a difference only the port. But I think he needs to drop intensity to 11 as his card is generating hardware errors only. Not sure about the specifics of his card, but some 7950's are not like other 7950's this seems weird but it's true. My sapphire 7950's have outperformed my HIS 7950's for some reason on the same settings.
