32-bit or 64-bit

HI Experts

I've installed an AMD Athlon II x2 260 on a gigabyte m68m-s2p and win 7 home premium 64 keeps showing as a 32-bit OS.  Is this a 32 bit processor?  I've re-installed the os twice.

Thanks,

HNM

I would question the OS. If Windows 7 Home Premium says it's 32Bit, then I would suggest that you really only have the 32Bit version and not the 64Bit

Another way to test would be to install more than 4GB of RAM. Since 32Bit operating systems can't address more than 4GB of RAM, if you installed 6GB or 8GB and Windows showed on 4GB (or less) as available, then you can pretty much guarantee that it's only the 32Bit version.

32Bit windows operating systems can't address more, and even that is not true at all, see http://en.wikipedia.org/wiki/Physical_Address_Extension

If you have a 64bit operating system install cd or install image and want to install it on a box with only 32bit CPU, you would get an error right at the installation.
For windows and most other operating systems, there are different installation cds for different architechtures (like x86 / x64)

A really easy and cheaty way to verify if your OS is 64 bit or 32 bit is to look in the C:\ Drive.

If you have two Program Files folders, one saying "Program Files" and the other saying "Program Files (x86)" then you have a 64 bit Operating system.  If you only see the one "Program Files", then you have a 32 bit OS.

Ah ha...picked up some interesting point here which I've seen it on site the other day..............................................If you have two Program Files folders, one saying "Program Files" and the other saying "Program Files (x86)" then you have a 64 bit Operating system.  If you only see the one "Program Files", then you have a 32 bit OS.
