Windows 7: Will a 64 bit version of wndows work well on a core two due processor?

I have a Pentium D 3.4GHz processor on my desktop with 4 GB Ram, with a 32 bit Windows 7 installed, will installing a 64 bit version+ adding ram improve performance with my processor?

Please use this tool to update your profile specs or at least mention it here ...

if you are referring to Intel® Pentium® D Processor 945 or 950 (4M Cache, 3.40 GHz, 800 MHz FSB) then its instruction set is 64bit and you should be able to run Windows 7 64bit on it... but then again we would need to see the actual specs I asked you to confirm

I'm sorry for the confusion, the profile specs I had posted were for my laptop but now I'm asking about my desktop.

Profile specs updated using info from the device manager as the tool required a .NET framework that I don't currently have

Well based on the specs you would be either using the Intel pentium D 945 or 950 both of which are 64 bit capable. You can install the 64 bit windows on it. But max RAM for the motherboard is only 4GB so you can't add in more... So you are good to go.

Hope this solves your doubt... If solved please mark the thread as closed and Rep those helped

Thanks centaur78. It's nice to know that I'm ready to go 64.

Please tell me if the following logic is correct:
On the current 32 bit Windows, I have 4GB RAM but only 3.25GB is usable, since I can't add any more then the only reason for upgrading to 64 bit would be to access that 0.75GB which won't make much difference in performance or speed.

Yes, you'll never be able to access that .75gb as its system reserved.

At your current setup i don't see any point for you to upgrade to 64 bit unless you need to do some serious work like Autocad or 3D or programs that are CPU intensive

if you want to know the allocation of your RAM...

go to run > type "resmom" and click on the memory tab... It should show you basically how its allocated.

Ok so it looks live I'm going to save myself the hassle of upgrading to 64 bit.

Thank you all for your answers

Well if you still need to go ahead with the upgrade you would need the change the motherboard that supports your processor to a one that can take in more ram .. and in some case you would probably need to change the processor... which again is like buying a new system..

Do rep the those helped. thanks
