Hey guys,


Title pretty much says it all, if i go into the task manager it says "Physical Memory Total: 3143528?

Whats wrong?

Thanks in advanced!

If you're sure you have a 64-bit OS then you may have a faulty ram module or not connected properly

There is nothing wrong with your computer, part of the 4 GB RAM might be used by your graphics card

A part of the RAM - 8 MB to be specific is used as Video RAM or Graphic RAM. This is NOT an error in diagnosing amount of RAM present in Windows. This is the way how it works. It's not a problem.

Oh, that might be it

You use an integrated graphics chip?

I use an Nvidia Geforce 7900GS

That's strange. Can anyone explain me why an external graphics card uses shared memory since it has its own?

I would like to know also if its not the video card then i have no idea why im getting 3gb instead of 4gb :S

there are some cards that are made to share memory when its memory fills up you can turn it of in the nvida control panel i think i know you can with ATI

Total 4 GB memory is the limitation of 32-bit OS.
