245MB usable memory out of 512MB GraphicsCard

Specs: Windows 7, Pentium Dual-Core 3.2Ghz / 8GB DDR3
Ive recently upgraded my computer with a
ATI Radeon HD 5450 - 512MB

And for some reason in DXDIAG it says that the memory of the graphics card is only 245MB.
Now i did some testing in games, and in GTA IV, it says i only have 245MB to use.
Ive ran Black Ops, and everything maxed out, except for resolution (1024 x 800) ran awesome!
I went onto the "Can you Run It" website, and the site even says that i have 245MB of video ram!

I dont know what is going on, but i know im supposed to have 512MB of DDR3 VRAM but i only get 245MB

My System Specs:

Intel Pentium Dual-Core 3.2Ghz
8GB DDR3 Ram
ATI Radeon HD 5450 -512Mb-

Is there a way to maybe get the card to share some of the system memory?

p.s. i dont care if GTA IV doesnt work with out lag cause i got it on xbox, and can play there.
and i know this isnt the best graphics card for gaming, but this is a budget build.

You are not telling the truth http://www.tomshardware.com/reviews...

Use GPUz to see memory size and how much video memory is used.

Windows 7 has already done it for you

The HD 5450 isn't much of a gaming card. It has too few stream processors (80) & only uses 64-bit memory. It's a general purpose / home theater card.

I am telling the truth! my resolution was lower, but everything else was turned out and/or maxed out. and it ran smoothly. atleast 30fps and no lag. the AA was turned onto x4
