    Default graphics card memory and system memory

    I have a 2-part question:-

    1st) Under a 32-bit OS, max system ram available is about 3.3GB out of the installed 4GB. Now, as the memory of a graphics card 'eats/mirrors into' the system memory, so a 1GB graphics card will tie up another 1GB system ram of the 3.3GB, leaving 2.3 for the system to use.
    So, the way to have more available system memory is to use a 64-bit OS which can handle more than 4GB system memory.
    Is this a correct description?

    2nd) When one goes from 1 card to two cards SLI and even to three cards 3-way SLI, will the graphics card's memory keep adding up in relationship to the system memory?
    In other words, a PC has 8GB system memory and has a 3-way SLI (each card has 1GB VRAM). Does this mean only around 5GB is left for system usage?

    The 32 bit OS only allows 3.5GB usable RAM, but your discrete (add-in) graphics card's memory is separate from the system's RAM.
    If you are seeing your system RAM lowered by Graphics usage then you should disable internal graphics in your BIOS to recover it.

    If in fact you're using INTERNAL graphics, then that ~will~ draw from your installed system RAM.

    SLI uses both of the Graphic card's memory and Graphics processing units together to enhance the system's performance. Again, it does not effect the System's RAM.

    Also: You should go to a 64bit OS for better overall performance as soon as possible. You'll have all 4GB of installed RAM available to you, and you'll be able to install more RAM later on, and get the use of it too.

    Yeah, you really need to update to a 64bit OS, even most of the new laptops come with a 64bit OS.

    64 bit is the way to go nowdays.

    Neil hit the nail on the head with his description of ram usage and dedicated verses non dedicated video cards!
