32 bit to 64 bit RRS feed

  • Question

  • My computer came with Windows Vista 32-bit from Dell pre installed. I have an Intell(R) Core(TM)2 Quad CPU. Can I install the 64-bit version of Windows 7? What other requirements are there to have the 64-bit and what exactly is the difference/benefits?

  • You can't upgrade your 32-bit Vista but you can install a 64-bit Windows 7 in a dualboot scenario (clean install on a second partition/drive). In general, there are no other requirements than a 64-bit capable CPU + motherboard. The system itself should run faster and smoother than on 32-bit, then. But some of the benefits like applications running faster, larger memory access is provided etc. may depend from the 64-bit-capability of the rest of your hardware / software. If a program doesn't natively support 64-bit addressing, you may not see big differences in performance compared to running it on 32-bit. If the program is too picky, it may even refuse to run on 64-bit. And the benefit of using more than 4 GB RAM is merely theoretical if you don't have more RAM installed. And so on.

    Regarding the question 1, you can cleanly install Windows 7 64bit.

     

    Regarding the question 2, today's more powerful PCs often use 64-bit versions of Windows. If you're not sure what to download, just match the version you're currently running. Here's how to check.

     

    Hope it helps.

  • Yes, you can. Further more, if you have more than 3 Gib of RAM, you will utilize all of it. On a x32 you can only use 2Gib (3 with the switch, I know..).

    If you still want to, you can, like said here, set up a dual boot system where you simply choose when the computer starts which version you want to use. Don't worry, that's set up automatically for you.

    If you run any processor heavy applications such as a 3D rendering engine, then it will run faster on a 64-bit system since it can use the memory more efficiantly. Like Sanmartin said, some 32-bit applications can refuse to start but newer games and so on should have no difficulty. There's also a compatibility mode in Windows7 that can emulate the environment in Vista for instance if this is needed for the application to run.
