Can I upgrade my RAM?

[egnite987]

So I want to upgrade my RAM, right now my 2 main specs are:

-4GB RAM
-Windows Vista 32 Bit

If I upgrade my computer to Windows 7 64 bit I heard that I can upgrade to 8GB of RAM.

The thing is, is that I did a little research and figured out this is my motherboard:
MSI (Micro Star) MS-7529 (G31M3-L V2)

And these are my specs for my memory:
DDR2 PC2-5300, DDR2 PC2-6400, DDR2 PC2-8500, DDR2 (non-ECC)

My question is, If I upgrade my computer to Windows 7 64 bit will my computer allow me to upgrade to 8GB of RAM even with the motherboard and specs my ram has right now?


*I used crucial.com to find all this out and It also states that my maximum number of RAM is 4GB? Does it say this because I'm currently running a 32 bit OS?

Oh LMAO, I meant Australian Dollars. :s , Thanks so much for your help again! I did some conversions but all together it turns out to be cheaper then American Dollars, which doesn't make much sense to me. (I converted the prices from newegg)
