based on the information from device manager that showes the gpus in this order :6900,5700,5800,5800 I changed the .bin to this : --shaders 8000,3200,6144,6144 . But my hashes are still crap. Drivers Cat 12.8 and App 2.5.

DRIVERS AND OPENCL SDK

The choice of driver version for your GPU is critical, as some are known to
break scrypt mining entirely while others give poor hashrates. As for the
OpenCL SDK installed, for AMD it must be version 2.6 or later.

You're 2.5 installation is doing nothing. The fact that you're even mining means you're prolly using the build in OpenCL runtime that came with 12.8. It prolly mucked something up in the process, however, but idk.
