Phenoms launch dumbed due to L3 cache errata

Sadly for AMD, the Phenom launch was dumbed down by a nasty bug that stopped AMD from launching a 2.4 GHz variant (9700).

At the same time, problems with the OS freezing were solved by a BIOS fix inside the motherboards that actually reduces performance between five to 10 per cent, since that BIOS update did nothing but ordered a processor to avoid that ill-fated corrupted cache data.

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.
