    Hi!

    I recently acquired a new Samsung Q320 laptop and promptly fitted a new HD with a clean XP install (still don't like Vista very much).
    With 4GB RAM installed, I am a bit surprised by the small amount specified under "Available Physical Memory":

    Is this normal?

    I also have a Dell M1330 with 4GB installed, and it shows a fair bit more available RAM:

    Many thanks in advance! :)

    Welcome to TSG!

    How much memory does the Graphics adapter have?
    For example, if you have two identical systems, but one has a card with 512 MB Video RAM on board while the other has 1 GB Video RAM on board, the 2nd will show .5 GB less available RAM.

    If the system is using an integrated controller, there is usually a BIOS setting to specify how much RAM the Video card is allowed to use, and whether that RAM is Shared or Dedicated.

    Usually, Shared will show as available, Dedicated will not.

    Ah! That would explain it!
    The Dell has a 128 MB card, but the Samsung has 256 MB.

    If I were to change the RAM usage of the Samsung card, would that affect graphics performance? I don't really play games on it. Have a PS3 for that :)

    Thanks!

    You also have to take into account that the 32-bit version of XP and Vista don't utilitize the full 4 GB of RAM. Depending on the computer setup, about 3.25 GB on the average is used.

    And both of those computers have different hardware and software requirements, which would account for the difference in the amount of available RAM.

    Yeah, I thought that might be the problem. But 2.37 GB available memory still seems pretty low when I have 4 GB installed...
    Also, from the research I've done about the graphics cards, the memory is dedicated, so should not affect the amount I see as "available". So I still don't understand why one machine is showing more available memory than the other...

    If it's showing 2.37 GB of available memory, but your computer is recognizing and utilizing only 3.00 GB or slightly more than that, then 2.37 GB isn't low at all.

    When you right-click MY COMPUTER and click Properties, what's listed for the RAM amount?

    It's showing 2.96 GB

    I know it's not HUGE deal, just interested to find out why it does this :)

    Since the System Properties window is showing 2.96 GB of RAM, it appears that computer is utilizing about 3.2 GB of RAM.

    Aha, so it seems to be a bit of an inexact science :)

    Thanks for the help!

    Just to add, though the memory on a graphics card is dedicated, the addresses used to access it by the system still come out of the pool of available memory addresses, so that will reduce the amount of Available Memory.
