Mum's desktop now got 4gb Ram-Any better?

  buel 22:56 12 Jun 2009

Hi, my mum has a Vista desktop that had 3gb of Ram(two 1gb sticks and two 512mb sticks) and worked only 'ok' but she bought an extra 2gb(two 1gb sticks)from Crucial so now has 4gb of Ram and she says it is much quicker. When i click on 'My Computer' and choose 'Properties' it only 'sees' 3.5gb (i've heard that Vista will only ever use 3.5gb), please can you tell me does the pc actually use the extra half a gb?

You shall be able to look in the bios and it shall see the full 4 gig u have there. When you go to "My Computer" it will only see varying amounts of the actual amount of ram that you have, but the computer shall still use all of the 4 gig.

The amount of RAM that can be used also depends on whether you have a 32 or 64 bit system. Theoretically 32bit uses up to 4GB and 64bit up to 128GB.

3.5 Gb is about correct for 32 bit Vista.

It all depends on what ram other parts of the system use. 32bit versions of Windows can utilise a maximum of 4GB, this includes video memory. I myself have 4GB fitted to my Vista machine but can only access 3.07GB because my video card uses 1GB of ram.
