64 Bit Question

I need some help with understanding this "64-Bit" thing. I have a laptop that came brand new with Win7 64 Bit OS. I have heard that 64 bit is better that 32 Bit. Here's my question... Does the hardware that a 64-Bit OS is installed on have to be a "64 Bit" machine?

Thanks

if you are running 64-bit OS you can ran 64 bit applications/software as well as 32-bit. Difference is that if you have 64-bit OS (what means your CPU supports 64-bit) it can handle 64-bit apps/SW more effectively that 32-bit.
You won´t do anything wrong if you will have 32-bit apps installed and in use, but if you have option to install 64-bit version it´s vwise to do it (if you do not have any compatibility issues.
Also on 32-bit win OS you can use max 3,2GB of RAM, on 64-bit win OS you are not limited by OS (OK, there is a limit but not just 3,2GB, but motherboard manufacturer so you can easily use 8 GB, 16GB or more RAM (if mobo allows you)

You can have it on a 32-bit machine as it is backwards compatible, but I do not recommend this.  64-bit supports the newest hardware standards, namely that it allows computers to go beyond 4GB of memory, which is becoming the standard these days.

Yes, the processor has to support 64 bit to run a x64 operating system.

I'm not sure if I totally follow your question, but I think you're asking if do you need to have 64 bit hardware to use a 64-bit OS?
If so, the answer is Yes, but only for a narrow range of components - essentially the CPU, which then also defines the motherboard.  
Everything else will just do as it's told.

A 64-bit Operating System needs a 64-bit hardware machine (as has been noted above). Most of the drivers (NIC, video usually, audio and so on) need to be 64-bit drivers. Either the vendor will supply both or a package that will self select.

From there, it gets murkier. Office should be 32-bit. Microsoft continues not to recommend 64-bit Office. Adobe is 32-bit. So then Flash, Shockwave, and Java are all best 32-bit.

Other packages may be either if they do no rely on Office underpinnings. So for example, WinZip is 64-bit, and I have a bunch of techie packages that run 64-bit.

There is no drawback to 32-bit Office. It works fine. The 64-bit operating system is faster and can use more memory and that helps everything.

Thank you all for your input...

Another question on this 64bit thing...


I can tell if my processor is 64 bit compatible? Is there a site that lists them or an app that can check?

Mine is a Dell 3.00 gigahertz Intel Pentium 4.

Thanks...

A Pentium 4 was never a 64-bit processor. Those were all 32-bit machines as far as I recall. They are single core CPU's.  See this Wiki reference article about that.

Hi John,

Thank you for your help. I pinged the Dell site and found the configuration of my computer. yes, it is 9 years old but thank God it still works well. I have 8MB of ram installed with XP. Sooooo only 3.25 MB of ram are currently being used. I am upgrading to Win 7 32Bit, but would like to go to 8.1 64 bit is I can.

I would just like to be sure. Thanks again to all for helping me out.

Also.....

I just used Belrac to check my configuration and curiously enough where it mentions the processor it indicates that it is "64 bit ready:. I not sure what that means exactly. I am not even sure if this Belrac app is accurate.  Thanks for your expert input.

You would need something more modern than that to run Windows 8.1 Pro 64-bit. That is what I am running now and the laptop CPU has 4 cores.

Thanks John... Another question...

In your opinion do you think I can run Win7 64 Bit on this machine?

Even though the "initial 32-bit x86 instruction set of the Pentium 4 microprocessors was extended by the 64-bit x86-64 set" (Quoted from Wiki above), I don't think this means it is a 64-bit machine (like modern ones) so then it is not likely to run Windows 7 64-bit.
