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.
