ATI MOBILITY RADEON 9000 IGP - Upgrading Video Memory

    All right, here's the deal.

    I bought a Toshiba Satellite A75-S211 about a year and a half ago.

    The Integrated Graphics Card (the Mobility Radeon 9000) said that it had 64 MB of shared video memory, but it was user expandable to 128 MB.

    So I did that.

    But, I was reading a review of the system on

    And a user said that he had kicked the video memory up to 256.

    Is he lying or is there a way that I can do that?

    I know that it is shared memory from my total system ram, but i just bought and installed an extra GB of ram, so I have more than enough to share, if it is possible.

    I use the system for mostly doing graphic work (in photoshop, illustrator, dreamweaver, etc..), but I also like to play my games on it. And a 100% increase (i.e. 128 < 256) would be awesome for the latter, just as the previous 100% (64<128) helped exponentially.

    Thanks in advance.

    I think that guy is:
    a) A liar
    b) Someone who doesn't understand what the hell is going on.
    c) He COULD have gotten a modded bios...
    d) He somehow got hypermemory to work with shared memory (I've been trying to do that for months).

    That's what I was thinking, but I just want to be sure..

    Unfortunately, ZDNET doesn't have a way to contact other members (at least, not that I could find), so I couldn't just ask him directly...

    Thanks for the quick reply tho.

    Can anyone else shed any light on this for me?

    I am assuming your using the newest BIOS for your laptop. If not you can download the Toshiba Satellite A75-S211 from here:
    (please double check that this is your correct BIOS, i will not be responsible for a Bad BIOS flash)

    In theory, the ATi Mobility Radeon 9000 chip can be equiped with 256MB, however such UMA allocation is strickly dependent on the BIOS revision, the installed system memory, and the OEM motherboard design.

    If you've installed the latest BIOS, new UMA (shared memory) options will become available. It is possible that it would take more than 1 GB to unlock the shared memory option of 256. For example, it may take 1280MB or something just over.
    (ie// 1GB SODIMM and 1 256MB SODIMM)

    However, keep in mind that the AGP apeture size should automatically adjust in notebooks with more memory installed, and this will allow the system memory to serve as a graphics data cache as well. I would also recommend changing your Page file size's upper and lower limits to a minimum of 2048MB, this should help a little if you use memory intensive programs.

    But too be honest, i haven't heard of integrated chipsets going over 128MB shared UMA from that particular ATi notebook graphics chip generation.

    Take care.

    Then, in theory, I should be fine if it allows me to do it.

    I have exactly 1280 (1GB stick, 256MB onboard).

    I just put a new version of XP Pro on here, so I'm gonna try this soon.

    Also, where do I change the page file settings?
