Just tried my fx5200, clock locked, help

remember the thread about the old 64mb, 64 bit fx5200 I had which the mx440 eats it? This time mines 128mb and 128 bits and its nearly as fast as a stock ti200 which arent bad at all! one problem however, it is still clock locked! man I hate it when they decide to lock it, so any idea what to do? I also know the radeon9500s were clock locked but some guy figured a bios hack fixed the lock. some radeon9000/9200 and 9700s were also locked. do I need to flash the bios or what?
