Summary: I was able to unlock the 4th core on mine and is stable. I was also able to 3.5Ghz out of it after increasing the front side bus. it has performed very well so far and I would recommend it one.
Great CPU 3 core can be unlocked into a quad core easy!

Summary: This cpu can be unlocked into a quad core. When you do it correctly (with certain motherboards) can be unlocked in to AMD Phenom II x4 (denob or w/e it's code name is called). It requires a motherboard with a certain north and south bridge. (look on google).
Summary: Overclock to 3.2Ghz simple, I am sure it will go higher. Wish I could unlock the 6MB Level 3 Cache, or the 4th core, motherboard doesn't support it. I was concerned the 512k level 2 cache would hold it back, I can't notice a difference from a x2 260 with the 1MB cache.
Summary: Best for a limitet butget just like me. and for overclockes I have this one OC @ 3.4 V1.42, this mean it has good room for overclock, and IF YOU ARE LUCKYLY ENOUGH you will get one of those with the 4st core not defective so you can unlock it.
Summary: I bought this after buying Sempron and unlocking would yield program lockups. I decided that multi-core was what I wanted and the Athlon was born multi-core. I inadvertently unlocked in the bios and was surprised when I was rewarded with a QUAD CORE PHENOM complete with level three cache.
Summary: Excellent processor, I recommand strongly. It's fast, can be unlocked 4th core, doesn't warm a lot and can handle big applications for a very little price. For me it's the best performance/price rapport of the moment.
