CUDA kernel launch configurations for geforce 8200m w compute 1.1

[gokuminer]

"
CUDA kernels do the computation. Which one we select and in which
configuration it is run greatly affects performance. CUDA kernel
launch configurations are given as a character string, e.g. S27x3
 
                       prefix blocks x warps

I am running a geforce 8200M laptop and a AMD Athlon X2 64 cpu (Dual Core).

I am able to run cudaminer with these settings cudaminer.exe -i 0 --no-autotune -l S14x3 -o stratum+tcp://pool.litebonk.com:3333
but the results do not  validate on cpu.
