Hi elnaka,

You can use 64bit anytime as long as your processor supports it, Find out by running CPUID for detailed infomation on your CPU/Motherboard and memory speeds.

Thanks for your help.....here is a screen shot of the CPU-Z.....supports??



but i need to know what are the differences?
Is it good for me to use it or not?!
Thanks again

Hey Elnaka,

Your processor is 64bit capable (see extension EM64T in CPUZ), If the rest of your hardware and devices are 64bit capable then you can run it for sure.

basically the difference is you can use all 8gb of ram, your pc is ready for future generation of software & vista acts a lot smoother.

Thanks alot......and i got some more useful information ....so that it may help others

A description of the differences between 32-bit versions of Windows Vista and 64-bit versions of Windows Vista

What should u have to use a 64-bit version of Windows Vista:
You must have a computer that has a 64-bit processor. Also, you must have 64-bit device drivers for the devices that are in the computer.

Differences between 32-bit and 64-bit versions of Windows Vista:

Memory accessibility (Can access more than 4 GB).
Memory management (Uses of 64 bit packet instead of 32).
Enhanced security features.
The greatest difference is the ability to access physical memory (RAM) that is above the 4-gigabyte. This physical memory is not addressable by 32-bit versions of Windows Vista. A 64-bit version of Windows Vista supports from 1 GB of RAM to more than 128 GB of RAM.


What to consider when you install a 64-bit version of Windows Vista: • 64-bit device drivers may not be available for one or more devices in the computer.
• Device drivers must be digitally signed.
• 32-bit device drivers are not supported.
• 32-bit programs may not be fully compatible with a 64-bit operating system.
• It may be difficult to locate programs that are written specifically for a 64-bit operating system.
• Not all hardware devices may be compatible with a 64-bit version of Windows Vista.



Different versions of 64-bit Windows Vista: Windows Vista Home Basic -4 GB of RAM
Windows Vista Home Premium -16 GB of RAM
Windows Vista Business -128 GB of RAM or more
Windows Vista Enterprise -128 GB of RAM or more
Windows Vista Ultimate -128 GB of RAM or more
