16 MB of RAM missing

Can anybody explain this.

I habve an IBM Think pad (XP pro + all updates etc.). The RAM stick has labels saying 256 MB, but My Computer/Properties shows 240 MB. I was assuming this meant there was a problem with the RAM so I purchased a new 512 MB stick.
I installed this and checked the RAM again and it showed 752 MB - 240 + 512. I then removed the suspect RAM stick and found that I had 496 MB of RAM. 16 MB down again.

Which ever stick is in first shows 16 MB down on it the proper amount, while inserting the second stick increases the total by the full figure.

Can anyone explain what is happening?

16mb is for graphics. your graphics chip is onboard and uses system resources.

Check to see if your Graphics card/chip shares the RAM, you will probably find thats where it is.

Cuddles - I would guess you're right (as others suggest the same reason), but would I check?

Sorry, lost the ability to type correctly, meant to say...

HOW would I check?

Check in the manual for the laptop if you do not have one click here click here

either of these programs:

belarc click here

everest click here

will build a complete profile of your computer.

Alternatively look in device manager, or right click the desktop and choose properties, click settings then advanced, click adapter and it'll tell you the graphics you have.

That's a lot, both for solving my confusion and for such prompt responses.

Cheers.
