Default 4GB of RAM, but Windows says 3GB

So I installed 4GB of RAM

http://www.newegg.com/Product/Produc...82E16820231122

Windows says 3.00GB of RAM in the Control Panel System thing...

What's the deal?

You proberbly have a 32bit OS, which can only address 4GB of memory - that's INCLUDING your graphics card.

Well my graphics card has 512MB of RAM...so...what the heck? Shouldn't I be getting 3.5GB then?

does your graphic card have hyper memory? you could be allocating more ram than you think to your graphic card without knowing it

Or if the onboard video (if any) isn't disabled. Soundcard, LAN, etc. also use some of your memory.

That only uses a few megabytes, at most. Sound card could have some onboard memory, I suppose. Either way, it's a 32 bit OS limitation.

I think virtual memory (page files) and caches are considered too.
