Recent drivers from AMD disable the tweaking ability of the some software like MSI Afterbruner or Trixx. I use the Driver 12.8 and Shappire trixx to overclock my Radeon HD6950 from 800mhz to about 950mhz, which is much more than the AMD Overdrive application let me, overdrive let me to the max of 840mhz core clock. You may try with older drivers to see if the overclock ability will come back.

MSI afterburner works fine for me catalyst 13.1. Not sure what the problem is.
