Half Ram available?

[Warhawk15]

I did some searching online and on these forums, but couldn't find much.
One site said that if you run Windows 32 bit, it will use half your RAM.

I have a Windows 7 32bit and it only shows 2gb available for use.
I have 4gb on my air tho...
Is there some way of changing this in BIOS(never touched those before)?

It wasn't a problem before since the games I've played so far haven't had a problem.
But I just downoaded Borderlands GOTY($7.50 on steam) and it uses up all the RAM available and isn't as smooth as it should be, even with the settings as low as possible.
I'm sure if I had all 4gb to use, it would be nice and smooth.

This is all in Bootcamp btw.

What to do?
Sorry if someone else already posted this, I did search.

Your only real solution is to upgrade to a 64 bit version of Windows.

If you didn't get 64 bit media with your license you can get replacement media from Microsoft or download an official ISO to use with your key.
