The problem with L3 cache caused performance reduction on all clock speeds and yes, Phenoms 2.2 and 2.3 GHz are affected as well, but it was really noticable at 2.4 GHz. BIOS run-around caused a 2.4 GHz part producing performance of 100-200 MHz slower parts. Of course, standard disclaimer in some rare-found, practically laboratory-only instances applies here.
