Qosmio G50/402 - How to use 8GB RAM?

I have Qosmio G50/402 with 8GB RAM installed although the useable is only 4GB.
Is there any way to use the 8GB?

Hello
This can have different reasons.
Firstly you have to check if your notebook supports 8GB RAM. Check the specifications of your chipset but as far as I know Qosmio G50 should support 8GB RAM.
Furthermore it would be interesting to know what OS you have. To use full 8GB RAM you have to use a 64bit OS.
And what type of modules you are using exactly? In worst case the new module isnt compatible with your notebook. Normally the best option is using two identical modules from one manufacture, e. g. Kingston. I have very good experience with these RAM modules for notebooks so I can really recommend it.

  • Qosmio G50-12K - BIOS update for 8GB RAM support?

    Hi
    I just upgraded my Qosmio G50-12k to 8GB RAM and installed Windows 7 64bit ultimate. The Windows see 8GB RAM but can only use 4GB. I have BIOS version 2.0.0 I wanted to upgrade to version 2.10 "P0060v210.exe"
    When I run the BIOS update i get this massage [Error] BIOS Update is not supported OS. Unsepported OS or service pack installed.
    I am really clueless on what to do. Can Qosmio G50-12k BIOS be updated to support 8GB RAM?
    please help !
    thanks allot eliot

    Hi eliotah,
    In my opinion BIOS update is worth a try!
    But I dont understand why you cant make this update. Have you installed Toshiba Value Added Package? In my opinion its necessary to start the BIOS update.

  • How to use 4GB RAM on Windows 2000

    Hi,
    We use a third party application that parses weblogs and generates statistics.
    The application gives OutOfMemory exception when the weblogs are hugs.
    I am wondering if doing "editbin.exe /LARGEADDRESSAWARE java.exe" is going to help.
    I have 4GB of physical RAM and I have /3GB in boot.ini in Windows 2000 Advanced Server.
    Thanks,
    Anurag.

    How to use 4GB RAM on Windows 2000You are never going to use 4g on a windows box. The maximum addressable space is 4g. Normally the OS reserves 2g. Which means the maximum addressable space for an application is 2g.
    It is supposed to be possible to increase the addressable space to 3 gig. And also increase the JVM space. However, there are risks. The following thread suggests a way to do this

    Hi,
    For this problem, in my opinion, it would be better to make troubleshooting with Windows startup diagnosis tool, you can refer to the contents of the link below for more details:
    http://social.technet.microsoft.com/wiki/contents/articles/10128.tools-for-troubleshooting-slow-boots-and-slow-logons-sbsl.aspx
    Since you said it work fine in Safe Mode, you can also check is there any program start up with system, then try to disable them for test if Windows works fine.

  • Qosmio F50-125 - How to use TV-FM Tuner in Windows 7

    Hello,
    I am using Qosmio F50-125 and I just upgraded to Windows 7.
    I just now found out that I have a TV tuner on my notebook and I dont know how to use it.
    First I dont have drivers for my TV tuner and tried to download something like TV-tuner driver v.2.3.3.31 from the toshiba website, but there is not a typical setup.exe but just some files inside.
    If you could tell me a bit more about how to use my TV option and how to install the proper drivers I would be truly grateful.
    Thanks in advance!

    Hi mate,
    Friend of me has also Qosmio F50 with TV Tuner and Windows 7 now. As far as I know the posted instructions from the other users are correct.
    First you have to extract all files. Then go in device manager and right click on the TV card (I think its marked with yellow exclamation mark). If you right click choose Update Driver and in next windows choose the advanced installation (second point). Now you have to choose the driver directory yourself and navigate to the folder where you have extracted the files. Click on OK, Next, etc. and the driver should be installed properly.
    Maybe you to restart the notebook but this shouldnt be a problem! ;)
    If you have more questions, please let us know! If you need more assistance I can ask my friend again for further details.

  • Qosmio G50-115: How to upgrade Home Premium to Ultimate

    Dear Friends,
    I am a teacher in a local college. We decided to buy Qosmio (Device name: G50-115, , Device number: PQG55E-01J00GEN, Product Group: QOSMIO) for our department. We bought two for the time being for trial. But now my job is on the sword.
    These laptops are pre-intstalled with Vista-Home Premium -SP1 and we need to upgrade these to Vista Ultimate. We have a Windows Vista Ultimate DVD but that is without SP1 on it. When I run and try to upgrade it rejects the upgrade as the installed version is newer than the version which I have. Microsoft is of no help, they said you bought it....
    Microsoft advised me to uninstall SP1 but I cannot do that because there is no option in ControlPanel for this.
    If I do clean install I will lose all the Toshiba's nice software. I made a recovery disk but do not think that I will be able to install these software. Though I can download all the necessary drivers but I am interested in factory installed utilities/software.
    Would you please advise me what to do. Is there we can get all teh Qosmio software on a DVD for instalation.
    Regards,
    Dr. Sayied

    Hi
    As Raver said use vLite free software. This software would allows you to create a new Vista Ultimate DVD and you could include the SP1 which you could download from the Microsoft.
    At the other hand you could also use the Vista Ultimate DVD to install the Vista on the Qosmio G50.
    The Toshiba tools and Vista driver can be downloaded from the Toshiba Europe driver page.
    After the Vista Ultimate installation you could update and install the SP1

    Actually the unibody machines switched from an Intel chipset to the NVidia MCP79 chipset.
    The thing is tho, what I dont understand is why both late 2008 and mid 2009 motherboards use the came motherboard (both using the same chipset) and still limit the user from doing this. I thinks its just apple's way of saying "Buy a new computer"
    Below in the links, NVidia say that their chipset used in the late 2008 systems can support 8GB but its up to Apple if they want to enable it or not.
    It's really not fair at all, its been proven that the late 2008 systems can support the update just by a simple EFI update. *Get on it Apple!*

  • Qosmio F30-127: How to use SD card - no SD card drive icon

    Could some one tell how to use SD in F30-127.
    I was trying to get picture from my SD card.
    I inserted into slot but no Drive ICON was displayed

    Hmmm. Please check if the SD card slot was recognized in the device manager.
    There should be no yellow exclamation mark!
    Other hint;
    - Remove the SD card from the slot
    - Go to the device manager and remove the SD card controller
    - Now reboot the notebook
    - After new reboot the windows should recognize and install a new hardware. This is a SD card controller.
    - Now try to insert the SD card again!
    By the way; did you use the compatible SD card size?

  • Qosmio G50-11R - Can I use two HDDs?

    About Qosmio G50-11R
    Does anyone know if it is possible to fit two hard drives in this laptop?

    >...but there is no connector. Is it possible to add such a feature?
    As far as I know something like this is not possible.
    The cover is the same for all Qosmio G50 models but some of them are delivered with one HDD only. In this case the mainborad is not the same as in G50 with two HDDs. There is no connector for second HDD and it cannot be soldered additionally.

  • Qosmio G50-136 - How to enable Hardware virtualisation

    Hi,
    I have a Qosmio G50-136 with an Intel Core 2 Duo P8600 that is said to be YES to intel virtualization technology (VT-x) by intel itself ( [intel|http://ark.intel.com/products/35568/Intel-Core2-Duo-Processor-P8600-3M-Cache-2_40-GHz-1066-MHz-FSB] ).
    My issue is that none of the bios settings available through HWSetup refer to hardware virtualization,
    So is there a way to enable it ? I'd like to run mac os x 64 bits in vmware workstation.

    > My issue is that none of the bios settings available through HWSetup refer to hardware virtualization,
    .and did you check the BIOS settings?
    From my knowledge the VT can be enabled and disabled only in BIOS.
    If such settings is missing or not supported, you will not be able to enable/disable VT

    I have a G35-av600 purchased last june. If anyone has any suggestions, let me know

    Hi
    Im not sure if I can help you because I know only something about the Qosmio G10 and G20 and your Qosmio seems to be a US notebook but I will try my best ;)
    On the Qosmio G10 for example you have to change the input settings in the Toshiba picture enhancement utility but I assume you dont have this tool preinstalled.
    But I think the composite in is a right jack to built the connection with the game station.
    I think in the Advanced graphic card settings you should be able to find the right options.
    Play a little bit with this settings.

  • Qosmio F30-140 - How to use Flash USB boot option?

    Thanks

    Hi
    I dont have Qosmio F30 so I cant test it for you but I think this options means that you can boot from an USB stick for example. Have you checked this?
    You cant boot from an iso file because you must create a bootable media. For example a Windows start disc or a Linux version that you can boot from USB stick.

  • Qosmio G50-10J: How to replace the Optical Disc Drive (ODD)?

    Hello there,
    the optical drive of my Qosmio G 50 is not working properly anymore, it reads only some movie-DVDs, but sadly no videogameDVDs at all, so I cannot instal any games.
    The warranty has already expired too. So I wanted to ask if it is possible to change the drive myself, if it is then how should I do it, and if by doing it would the laptop be in
    serious risk of getting damaged?
    I would be very thankful for every tip and every help you guys can give me!!!
    Best regards,
    a.z.

    But maybe the ODD laser lens is dirty. In my case I could solve similar issue cleaning the laser lens using a cotton-wool tip and alcohol.
    But be careful doing this!
