If you read the release notes, you'll find that this is because Vista will now report the amount of memory physically installed. It does NOT mean you have 4GB available...in fact, your amount of available memory does not change.

Regarding the OP's question/problem, 4GB of RAM needs two things:
1) 64bit OS
2) A 965 chipset or later

You have #1, you do not have #2. This is because, despite Intel releasing 64bit processors, their chipsets were not designed for anything but 32bit memory addressing until the 965 chipset was released (which is also when 4GB+ of RAM actually became financially feasible for most consumers). Even with a 64bit OS you are still only going to be able to use as much as a 32bit OS could.

I'm just sorry it isn't the answer everyone was hoping for

That's the upside and the downside of technology, the truth is either greatest news or the worse news. No matter what though, it is always best to be 100% sure of something in technology, and that means learning through experience or learning from others.

Default Re: DV9000T & 4G RAM revisited

It's also the downside of an immoral marketing department and an industry that does little to question anyone's claims.

"Intel releases 64bit CPUs!!" too bad the chipset doesn't support any of the main advantages of them.

"Intel releases Santa Rosa with 800MHz FSB!!" Too bad the only thing that can talk at 800MHz is the CPU itself. RAM isn't on the FSB, and only runs at 667MHz.

I'm glad I returned my dv9000 when I did.
