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 )

system RAM : 1GB 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 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

--thread-concurrency 1792 - work = 4.0Kh/s --thread-concurrency 3584 - crash = Error -5: Enqueueing kernel onto command queue. (clEnqueueNDRangeKernel) --thread-concurrency 5376 - crash = Error -5: Enqueueing kernel onto command queue. (clEnqueueNDRangeKernel)
Clearly your low system ram is screwing you over. Are you setting an intensity with those? --thread-concurrency 1792 will safely take -I 12

how much total ram do you suggest 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 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.
