How can I determine whether my processor is 32-bit or 64-bit? My processor is AMD Phenom 8450 triple-core.

You could search google/newegg for your particular processor, if you know it by name, and read the specs. The specs on your processor says: 64-Bit Support: Yes. http://www.newegg.com/Product/Product.aspx?Item=N82E16819103254 But i'd vote for someone else's answer if they could give a quick and easy way to check this without having to know your processor's model. Maybe it says in the bios on boot up? |

Another way would be to use CPU-Z. In addition to bitness (AMD64 or EM64T) of the processor, it will display other useful characteristics of the processor. Another way would be to check directly on the website of the manufacturer. Intel has a database of its processors here and it's quite nice. Unfortunately, AMD does not have such nice interface, but you can always go to their homepage and poke around. Here is the list of their desktop processors. VIA's processors seem to be listed here. |

Google for the processor's name. I found a wikipedia article about AMD processors. It states, that the 8450 supports AMD64, which means it is a 64Bit processor. |

You can use this program created by Steve Gibson of Gibson Research Corporation called SecurAble. This tool will not only tell you if it is a 32/64 bit processor, it will also tell you if the CPU supports hardware DEP protection and if it supports Hardware Virtualization. The program requires no installation at all. It simply uses a signed driver and communicates with the processor. |

To the best of my knowledge all Phenom series are AMD/64. If you need assurance and you're using a Linux or BSD OS take a look at what dmesg says on bootup. |

What OS are you on? In Linux / Mac OS X all you have to do is open a terminal and type |

Phenom x3 processors are basically quad-cores with one core locked (mostly due to defects). These are all 64-bit. PS - If you're interested, you should google to see and try to unlock your fourth core. A lot of AMD x3 have a working fourth core that can be unlocked to make your processor a quad core. |
