Everything looks in order there, but it's still failing. How much system ram do you have? Try forcing smaller multiples of 1792 for thread concurrency. Eg --thread-concurrency 1792 , then 3584, then 5376.
system RAM : 1GB ( free >512MB sfter system load )

This could well be a limiting factor because it needs both system and gpu ram... Maybe try concurrency of 1792 but increase lookup gap from the default of 2.

Come on guys, if not you no one can't help, give ideas    Embarrassed

Try this
--scrypt --worksize 256 --lookup-gap 2 --thread-concurrency 8192 -g 1 --intensity 16
--scrypt --worksize 256 --lookup-gap 2 --thread-concurrency 16364 -g 1 --intensity 16 (if buffer permit)
Result I don't promise

Clearly your low system ram is screwing you over. Are you setting an intensity with those? --thread-concurrency 1792 will safely take -I 12

The only way to do it in windows is to reboot into linux.

Note I am guessing this is the problem, I am not totally sure, so I really don't even know how much to recommend. I can mine on 4x7970s with 4GB of system ram at shaders of 2048 (you have less shaders on a 7950).

--scrypt --shaders 1792 -g 1 --thread-concurrency 1792

only --lookup-gap 2
and -g 1


I came to the result start from:
--scrypt --worksize 64 --lookup-gap 2 -g 1 --thread-concurrency {number of shaders by card} --intensity 10
and increase "worksize" and multiplying number of shaders in different variants

Edit: may be you have problem with system

Edit 2: try to reinstall (delete and install new) drivers (from amd.com)

--scrypt --worksize 64 --lookup-gap 2 -g 1 --thread-concurrency 1792 --intensity 10  - work = ~60kH/s

with increasing --thread-concurrency = Error -5: Enqueueing kernel onto command queue. (clEnqueueNDRangeKernel)
only whit --thread-concurrency 1792 work but poor

with increasing over --intensity :
on intensity 11 - Accepted 100% at 135kH/s
on intensity 12 - Accepted / Rejected = 50/50 at ~270kH/s  (target-miss)
on intensity 19 - Rejected 100%  at ~490kH/s  (target-miss)

with increasing worksize to 256 with intensity 11, thread-concurrency 1792 lookup-gap 2
Accepted / Rejected = 75 / 25 at 135kH/s  (target-miss)

Scrypt mining has now been merged into the master branch of cgminer, so you can switch to that and from now on it will be in the main release as well.
