Way back when AMD launched their Bulldozer architecture, AMD overclockers were disappointed by BD's performance in the old yet competitive X87 benchmark. The architecture was slow - much slower than its predecessor architectures - and it was frustrating to see >7GHz results ending up slower than the fastest Phenom II results.
The Stilt, a long-standing Finnish overclocker/hacker/tweaker, figure out some of the performance issues and released a small piece of software he named Bulldozer Conditioner. To not frustrate you with the technical details, in practice the conditioner gives your AMD hardware a nice boost primarily for SuperPI but also other X87 applications.
Five days ago, The Stilt released a new version of the Bulldozer Conditioner: V1.03B. The new version adds support for Steamroller, Kaveri, and Drago.
