I have unlocked the second core of the AMD Sempron and it turned to the Athlon II X2 4400e Processor retaining the 2.7GHz. Everything went faster and better. Can I unlock the third one? I see in the options in the BIOS that I can unlock up to 4 or 5 more cores. Is there something that needs to be watched out? Like the temperature, voltages or something? Any possible downsides?
