I have 4GB RAM installed, and I'm running on Windows 7 64-bit.

Why does Windows see only 3.24GB ? What can I do to make it see the full 4GB ?

It sounds like your chipset/memory controller isn't mapping physical RAM addresses into areas > 4 GB when they conflict with devices. If you're lucky there's settings in the BIOS that can fix it, if you're not then the chipset only supports 4 GB of RAM, whether it's used by devices or RAM and you're stuck. –  afrazier Sep 30 '11 at 18:11

The rest is probably used by your integrated graphics chip.

@Gold - install a graphics card - it doesn't have to be the best! –  ChrisF Oct 4 '10 at 22:08

When you boot your computer, go into the BIOS settings (should be a key like DEL or F12... try button-mashing). There it should explain how much RAM is being used by your graphics card. –  kispiox Oct 4 '10 at 23:55

See what's being used

Run devmgmt.msc

click on view then Resources by type, then expand memory. See what range your video card is using.

The best way to check what are the available resources use:

CPUZ And are you sure your OS is 64 bit cos, I get ~3.24 GB but the reason is that I am using 32 bit OS Best way to see your resources utilisation use NOD32's System Inspector
