What cdrsubron7 said... I wouldn't be surprised though, if the mobo isn't the limiting hardware factor. Do you happen to know what motherboard you do have? How many ram slots, and max ram it can hold?
The main thing though is the 32-bit Windows OS. Does your Windows license allow you to download and install the 64-bit version without having to purchase it? Some of the OM licenses don't, some do, but I do know that if you have a full-use Windows license, you can download the img file of the 64-bit version. Only problem is the install... Everything must be re-done on your machine. But, you might check into that.
Windows needs to allow the game more ram, especially if using FotRSU, and when using a 32-bit Windows. You are currently limited to using no more (often less than) 2 gig of the ram by the OS, which uses the rest of what you have for itself. You could use the NTCore applet or LAA and set SH4.exe to be able to address more ram, but Windows still won't allow it to. You also need to alter the Windows boot configuration. However, giving programs more memory to use, takes memory away from Windows, so you may have other performance issues troubles. You could try though, if you can't either get a 64-bit OS, or a new computer with a 64-bit OS...

This is a quote from a 2010 posting on stackoverflow dot com:
Quote:
To enable the 3GB switch on Windows Vista™ or Windows 7:- Right-click Command Prompt in the Accessories program group of the Start menu.
- Click Run as Administrator.
- At the command prompt, enter "bcdedit /set IncreaseUserVa 3072"
- Restart the computer.
To disable the 3GB switch:- Right-click on Command Prompt in the Accessories program group of the Start menu.
- Click Run as Administrator.
- At the command prompt, enter "bcdedit /deletevalue IncreaseUserVa"
- Restart the computer.
This does not display the increased size in the task manager as it still shows 2GB but now when my applicationx crash they indicate the current memory usage as 3GB

Now, to go a step further, you could try this:
Make Windows 7, 8 and Vista 32-bit (x86) Support More Than 4GB Memory
Now, I have not tried these out myself, since I no longer have a 32-bit Windows 7 install on a computer that can physically address more than 2gig of RAM, but I do plan on doing a parallel Win7 32-bit install on my current machine in the near future, and these were the two methods I've found thus far. I did do the "quote" version on Vista, and that definitely helps, but as I said, somethings on the OS side of things will slow down, because you are restricting the Windows "System" space. ymmv - as always, be protected, and have a back-up and emergency disk at hand... seriously.
I have done similar on a Windows XP machine just a few weeks ago (completely different methodology), and FotRSU will run much better, and you can even access the Museum, though it does take a ~LONG~ time to load. As I mentioned, I did the stackoverflow method on a Vista machine, and it worked there, though that has been a couple-three years ago, before FotRSU got so large, but I'm 99% certain it would work for that also. Windows 7 is about the same as Vista. Win8 is an animal of a different stripe, and might not be capable of doing the second method from raymond.cc's blog with all of the recent updates.
