Fourth Core Unlocked
Pros: Any fourth core can be unlocked if you have a bios that will allow it, simply setting ACC to on in your bios you can test it out. Yes the fourth core can be defective but there are people running theirs stable @ 4.0 Ghz unlocked on all four cores. And it does not matter what batch cpu you get, all that matters is if you get a functional core. So to all the "noobs" saying no amount of modding or hacking will allow it. AMD confirmed it and is making Mobo Manufactures update the bios so it can't be done. You can still downgrade your bios and unlock it though and who is to say no one is going to have modded bios to do so.
Cons: Nothing This chip, is amazing having 3 cores @ 4.0ghz if you luck out and get a good fourth core, you will save so much cash. Even though the fourth core/third core are useless in some games and you only gain a small FPS increase.
Overall Review: Please to the people saying you can't unlock the fourth core and if you do it will harm your CPU, you can't be for real. They disable fourth cores on perfectly good quads to meet the demand for the triple cores which i assume is Extremely higher then they anticipated with the bios allowing to unlock the fourth core. So there will be quiet a few PERFECTLY USABLE fourth cores on the X3s. Look at any overclock site, overclock .net or xtremesystems and do a search on this.
