    Why is there a difference in dedicated memory?? Performance wise- Video on vista is somewhat sluggish compared to XP.

    In the XP picture you have, it is counting both dedicated and shared memory. Vista breaks it down. You have a 64MB card, with the ability to borrow an additional 64MB in XP and apparently much more in Vista.

    How do I "borrow" more memory?

    Thanks for your response! :)

    It is handled at the driver and/or BIOS level, and cannot be set by the user in most cases. If you want to look, the BIOS might have a setting to control the max allowed to borrow, but I'm guessing that either (1) you will not be able to set it, or (2) you can set it, but your BIOS are already configured to give the maximum allowed to the card. It will borrow whatever it needs to get the job done, up to that max listed in XP and/or Vista.

    But in the 7400's case, it really will not be able to use more than 128MB effectively anyway. So the max XP will ever offer will easily be enough.

    so where does this 256mb 'shared' come from?
