Yes, 32bit is limited to a bit under 4GB memory but I believe that includes video memory also. The 64bit version has a MUCH higher limit, higher than your motherboard can actually handle so switching will help there, especially if you run programs that actually use large amounts of memory (Photoshop, 3D Cad, image and video processing, extremely large Excel files, etc). Understand though that you will need to do this as a completely clean install so you will need to back up your files to an external source, delete the current partition that contains your Windows 32bit Operating System, create a new partition, format, and install it there. Then you will need to update it, install your programs, personalize it, and put back your files. If your files are on a different drive or partition they should be OK but back them up since there is always a risk during partitioning and formatting. Programs will need to be reinstalled either way.

You have to be a little bit crazy to keep you from going insane.

This paper is about XP, but the same applies to Vista/Win7 32-bit & 64-bit:

✔ Best Answer
There is no legal way you are going to access all 4 GB RAM with a 32 bit client version of Windows. These systems have a 4 GB physical address limit which must be shared by RAM and memory mapped hardware which must have priority. Address space used for other things cannot be used for RAM. Typically this will leave you with about 3,25 GB usable RAM depending on your hardware. If memory is shared with video display this number will be further reduced.

There is no solution for this with a 32 bit client OS such as Windows 7. A 64 bit OS will allow access to all 4 GB RAM if the hardware supports this.

Installing a 64 bit OS for this reason alone is probably not worth the considerable effort involved. This would require a clean install of the OS and all applications.

It isn't worth your time to install 64 bit OS. You will loose 1G right off the top. See microsoft web page for minimum resources.

What little you gain, you end up loosing. Also programs and drivers become an issue.

If you had 6G or more then it might be a consideration.

Hang up and live.

The 4gb virtual memory address limit for 32 bit operating systems.
An example of 3gb working better than 4gb in a 32 bit operating system.

See Response 6:

A better explanation I've seen.

If you have a 32 bit operating system and you have installed 4gb (or more) in the mboard, the amount of that ram available to Windows and the user is
4gb minus the amount of ram your devices require or have.

E.g.
- minus the amount of ram shared with onboard video if you're using that
- and/or - minus the amount of ram your dedicated video card installed in a slot has.
If you have more than one video card installed in a slot,it would be minus the ram for all of them.
(and = Some mboard main chipsets have Hybrid video capability. If you have a PCI-E X16 video card installed in a mboard slot that is supported by that feature, it's often the default for both the onboard video and the video on the card to work at the same time, unless you change default bios Setup settings. In that case it would be minus the ram for both of them.)
- minus the amount of ram your sound adapter has, if that applies - e.g. sound cards installed in a mboard slot often have ram
- minus the amount of ram any other devices have, other than hard drives and optical drives, if that applies.
