ATI Mobility 4250 video memory


Hello

About the performance, the only important value is the amount of memory dedicated (i.e. the ability and the speed of the chips of RAM that are physically on the ATI card) and it cannot be changed.  The adapter can also borrow up to a certain amount of RAM of the notebooks, up to a certain maximum system - you can only possibly increase the amount of shared memory if it is not already at the maximum limit, adding more system ram, however this will not give you an advantage of performance access to shared memory is slower, and definetely would cause slow down.  For this reason, shared memory is never normally accessible.

You can check the current distribution by opening windows control panel, open tools and Information on the performance, then click on the link "View and print detailed performance and system information" - you will see the committed memory 256 MB and the current amount of RAM of the system which can also be "borrowed".

Kind regards

    Hello

    I don't have good news.

    Unfortunately, HP won't release Windows 8 drivers for your model.

    Also, there is no solution, allowing you to switch between the graphics card AMD and Intel.

    The whi only thing I can recommend is to install the graphics driver.

    This way, you will be at least able to install the driver from Intel.

    I also recommend to install all Windows updates.

    Note:

    Do not install the Intel graphics driver's go there (uncheck the update list).

    The ATI graphics driver on my laptop and those on the page of the product for my model are almost a year, in October of 2010. Are there newer drivers available that are compatible with this model? I play games enough low-end who should have no problem to get started on this thing, but they are extremely laggy. I read somewhere that a newer version of this fixes some OpenGL problems and I think that would help with some of my probs.

  • Video drivers for Satellite A200 (ATI Mobility Radeon HD 2600)

    Hello, I have Toshiba Satellite A200, with an ATI Mobility Radeon HD2600, and I'm very happy with it.

    I use it to Second Life, and so good. Recently, there were some new viewers for Second Life, and I'm not able to run the most recent version, as when I do, I see a window divided into 2 half black and half gray. I posted the problem in Programmer's blog, for both the viewers that I use, and the answer in both cases is that I have to update my graphics driver. I checked on the web site of Toshiba, but it seems that I already have the latest version of the driver, it's a very old (ver.8.452, published on 07-07-08)

    Is it possible to update the display driver? I tried on the AMD website, but it is not possible to download a driver for Toshiba laptop).

    Thanks in advance

    Hello

    You can download the mobile page AMD for the Radeon HD2600 graphics card drivers. But I think you need to install/update the driver through the Device Manager.
    Unzip the package downloaded to the folder created on the desktop.
    Then go to Device Manager and here you must use the advanced procedure that allows you to point to the folder (on the desktop) where the driver package was extracted.

  • I have separate video memory or a separate in my laptop video card?

    I have the pavilion dv7-6135dx.

    When I look to the top of my model number on the HP site, it says: ATI Mobility Radeon HD 6490 m

    When I go in my display settings, it says: Mobile Intel HD graphics 3000

    5093 MB total available graphics memory

    Dedicated to 1280 MB of video memory

    System video memory 0 MB

    3813 MB shared system memory

    What does all this mean?

    Can I have a separate video card or is it separate mounted to the motherboard video card?

    Best Buy said I could go 6 MB video memory to 8 or 12 MB I think. How can I know for sure.

    HP says nothing about the site on max video memory.

    Thank you

    Hello

    That just means your machine has TWO video 'maps' one is called Intel equipped with a video card and another called dedicated video card.

  • Satellite L30-134: how to change shared video memory?

    Hello

    I have a laptop L30-134 with 512 MB of ram and 64 MB of video memory shared.

    I can't change the virtual memory from 64 MB to 128 MB.
    I reed some messages in this forum but I have no option in the Panel as "FrameBuffer" and the bios hase no option for the video display adapter, I tried to install the latest ati driver but ich time I get an error is not configuration / compatibil card whit say out.

    How I change my card adapter video shared memory size?

    Thank you.
    PS: sory for my bad English... :)

    Hello

    Using the latest display driver (you can download it at toshiba), then you will have the option of frame buffer memory. The initially installed driver doesn't have this option. You will be able to use the memory of 128 MB for vga. If you put your L30 512 MB, you can use 256 MB of video memory. But I found no differences in the games between 128 MB and 256 MB.

    Best regards

  • Equium A60: ATI mobility issues

    I have an Equium A60 (PSA67E) with Celeron 2.80 ghz, 192 RAM, windows XP, and a 7000IGP ATI MOBILITY RADEON I bought jan 2005.
    I use the laptop and after 10 minutes a message appears and tells the driver has stopped working and I need a new. Which driver should I download for this stop happening? Ive looked to other people having problems with the infanite loop and its recommended location to download a bios updared will this help?

    I sent ATI and they said I need to contact toshiba

    It is also is so slow when I try and work on it, I've defragmented it but it works still slow. Would this becaure to have 192 RAM?

    Thank you for your help

    Hello

    First of all, I would recommend trying the page of the Toshiba driver graphics card driver:
    http://EU.computers.Toshiba-Europe.com/cgi-bin/ToshibaCSG/download_drivers_bios.jsp
    You choose unit and OS and download and install the driver.

    In my opinion, your device must use min 256 MB memory.
    But it is not only the problem of memory. Some software programs and background processes may decrease the performance of the laptop.

  • Improves we dedicate the video memory on my C50 - A Satellite?

    Hello

    I bought Toshiba Satellite C50 - A are a week and today I found it can run some games but not very well.

    Is it possible to change my dedicated video memory, because its 32 MB?
    My series 5E102406U here!

    Hello

    As much as I know there is no option where you can change it manually. Simply, it works automatically and depends on the RAM used in your laptop. With more RAM, more memory will be used for video operations.

    If possible post please model mobile exact and we can check specification and RAM upgrade options.

  • Can I change the video memory on my Satellite C855?

    My daughter has a Toshiba Satellite C855 1pj him for Christmas, we bought and wants to run the Sims 3 island paradise, but when she checks on systemrequirementslab.com he tell her that she has 64 MB of dedicated video memory and the game needs a minimum of 128 MB, is it possible to change or otherwise the game will still run on the 64 MB

    Thank you

    Karen

    Hello

    No, you cannot change this value manually. This is controlled by GPU driver.

    First of all, I must say that this laptop Satellite C855-1pj isn t gaming notebook because its supports a graph of Intel HD internal common chip. Playbook should be equipped with an ATI or nVidia GPU external.

    However, the computer laptop specifications page http://www.toshiba.co.uk/discontinued-products/satellite-c855-1gp/ said that the Intel HD supports up to 1 696 MB shared memory with 4 GB of RAM

    Eventually, you should be able to run the game, but with lower graphic settings.

    Try a different display of the L30 series driver. I PSL33 L30-134 and the use of XP, but I use the L30 PSL30 display driver, because this driver has the ability to change the size of the video memory (this option is missing PSL33 driver). I use not yet Vista, but maybe you should try another driver display L30 (for example the PSL30 L30-134).
