AGP Aperature size issues

  1. I've just switched from a GeForce 2MX to a Geforce 4 Ti4200 128 MEG.
    I use Windows 98SE and have 512 MEGs of RAM.

    I'm having some trouble with the AGP aperture size settings.
    I had mistakenly been informed that AGP aperature should be set to one half your Graphics Card memory.
    I now know this is not true and it should be set to half your RAM.

    My AGP size had been set to 32 MEGS with my previous card and when I installed the new card.

    When it is set to 256MEGS my display goes black and the computer stops booting.
    If I adjust the AGP aperature to any other size larger than 32 MEGS I can only display in 256 colors 640 X 480.

    Any ideas here?
    My card is running great BTW.
    My 3D Mark scores are right about where they should be.
    Just want to be sure I'm getting 100%

    Thanks for helping.

    Half your RAM rule is just as silly as half the vid mem rule.
    AGP aperture is supposed to compensate for lack of video memory, so the amount depends inversely on the amount of video memory.

    As your problem is concerned, you should install latest chipset+video drivers and maybe blame the poor memory management of Win98

    Just set it to whatever works, just shouldn't need AGP memory with 128MB of video memory. 64MB or so is fine

    This seems to be the concensus.
