First, there is no "special limitation."
Second, those other programs are lying to you. Your GPU has 1536 cores @ 975 Mhz, and WPA2 has ~ 14000000 instructions. Therefore the theoretical maximum performance for your GPU is:
1536 cores * 975000000 Hz / 14000000 instructions =~ 106.9 KH/s
To get 160 KH/s out of your GPU you'd need a clockrate of ~ 1458 Mhz, which your card cannot support.
Third, you've not posted your command line or even specified the attack you are running to obtain this number. Try running "oclHashcat64.exe -b -m 2500," it should be around 100 KH/s. If so, there is something wrong with your attack. Maybe you have a very high rejected rate due to testing mostly candidates that are less than eight characters.
