devilangel, welcome to the Seven Forums.

This would be why you are only seeing 3.25 GB of 4 GB (says for Vista by the exact same applies to Windows 7),

The system memory that is reported in the System Information dialog box in Windows Vista is less than you expect if 4 GB of RAM is installed

Quote:
For Windows Vista to use all 4 GB of memory on a computer that has 4 GB of memory installed, the computer must meet the following requirements:
  • The chipset must support at least 8 GB of address space. Chipsets that have this capability include the following:
    • Intel 975X
    • Intel P965
    • Intel 955X on Socket 775
    • Chipsets that support AMD processors that use socket F, socket 940, socket 939, or socket AM2. These chipsets include any AMD socket and CPU combination in which the memory controller resides in the CPU.
  • The CPU must support the x64 instruction set. The AMD64 CPU and the Intel EM64T CPU support this instruction set.
  • The BIOS must support the memory remapping feature. The memory remapping feature allows for the segment of system memory that was previously overwritten by the Peripheral Component Interconnect (PCI) configuration space to be remapped above the 4 GB address line. This feature must be enabled in the BIOS configuration utility on the computer. View your computer product documentation for instructions that explain how to enable this feature. Many consumer-oriented computers may not support the memory remapping feature. No standard terminology is used in documentation or in BIOS configuration utilities for this feature. Therefore, you may have to read the descriptions of the various BIOS configuration settings that are available to determine whether any of the settings enable the memory remapping feature.
  • An x64 (64-bit) version of Windows Vista must be used.
You have everything but the correct chipset, the 945G only supports up to 4 GB,

Intel® 945G Express Chipset - Overview

Basically boils down to regardless of whether you run 32 bit or 64 bit, you're going to run into the same memory limitations.

You could look at a motherboard that supports more than 4 GB, but this is one of those where it might be better to wait until you can do a full system upgrade. If you do decide to go for a board don't look for one with anything less than the G33 chipset on it,

Intel® G33 Express Chipset - Overview

as any under it are like your current board and only support up to 4 GB. As for what board to look for, as cheap as you can find as socket 775 is basically discontinued. Just check the board manufacturer's website if you chose one and make sure that it supports your CPU.

As for whether to run 32 bit or 64 bit with your current setup, seeing as the memory available won't change regardless of which you use I would just leave the 64 bit on it.

Unless you have a retail version of Windows7, you will also have to buy a new Windows7 when you change the board. If the OS came with the PC (OEM version), you cannot transfer it to a new board.

If I were you, I would not worry too much about the problem. The OS will work just as well with 3.25GB as with 4GB. You probably would hardly notice the difference.

If you look into Resource Monitor > Memory tab, you will see on the color bar that most of the times there is plenty of "available RAM" (the light blue and dark blue sections). Especially if there is still light blue left, there would be just more of it (unused) with 4GBs.
