Ok, to clear some things up...some people know this already but it's mainly for the thread starter.
The 2500 has barton core...same as the 3200+ which means it can run up at the same speeds in most cases no problems.
Theres nothing to unlock...it's simply the fact you can OC that particular chip rather easily and expect to get 3200+ speeds...You've already noticed that since you have yours at 2.3GHz so boom there you go, it's a 3300+ if you want since it's 100MHz higher..
Not all AMD processors are locked.
The XP-Mobiles have open multipliers, and also the AMD64s can have the multis turned down but not up with the exception of the FX series.
wow why would a company lock that kinda thing. AMD caugh caugh
Why would a comany charge more for a CPU that has less performance than the other company... "Intel...caugh caugh"
