Hi,

I have following System & I have been using Win 7 Ultimate 32 bit Version.

My question is can I install & use 64 bit version of Windows 7 Ultimate on this system ?

If not why ?

Any pros & cons of 64 bit OS ?

Processor : Intel Pentum D dual Processor 3.00 GHz

RAM : 2.00 GB DDR

HDD : 500 GB + Second HDD : 500 GB

Video Card : 256 MB Radeon X600

Sound : SoundMAX Onboard Integrated Sound

Thank You

A 64-bit OS will allow your PC to address 4GB+ of RAM. It will also run both 32-bit and 64-bit applications, of which few of the latter exist. A 64-bit OS will use a little more RAM to run the same apps. Windows 7 64-bit will not run older 16-bit programs.

In short, unless you have specific needs, stick with your 32-bit OS.

To install the 64 bit version you will need to format the system and do a fresh install.

A 64-bit operating system can handle large amounts of memory more efficiently than a 32-bit operating system, a 64-bit operating system can be more responsive when running several programs at the same time and switching between them frequently.

But is it best to have at least 4GB RAM to have the optimal effects and you will also need a processor that is capable of running a 64-bit operating system

Personally i would go for the 64bit but make sure the requirements are met!

Agree completely. I won't suggest 64-bit for a 2GB RAM. I myself use Windows 7 Ultimate 32-bit on my PC having 2GB RAM.
