a6040n CPU upgrade

[Silverthunder]

I would like to upgrade the CPU for this computer.  

The processor that I have right now is Intel Core 2 6320.  When I search the web for that, one search result is Intel's website and I was able to find the E6320.  I am not sure if that's the same thing as mine.

https://ark.intel.com/products/29754/Intel-Core-2-Duo-Processor-E6320-4M-Cache-1-86-GHz-1066-MHz-FSB...

This page seems to indicate that I have a 64 bit processor.  I always thought I had a 32 bit processor because I think I originally had 32 bit Vista and then I installed 32 bit Windows 8.1.  

In the user manual for the motherboard, it says, "The motherboard comes with a surface mount LGA775 socket designed for
the Intel ® Pentium ® 4 and Conroe processor in the 775-land package."

I searched the web and found a page on toms hardware that said that the best processor that the motherboard will support is the E6700.  This, too, looks like a 64 bit processor.

I see that on Ebay, there are a lot of these processors available from China.  Are those processors maybe counterfeit or that's highly unlikely?

If I can switch to 64 bit, are there other things that I have to do beside install a 64 bit operating system?  For example, any changes to/with the BIOS?

@Silverthunder,

Your system OS is 32bit.  A 64 bit processor does not matter.

CPU chips per your board does support the E6x00 chip.
