Satellite U200 - 10 H PLUA0E recognize only 3, 2 GB RAM - 4 GB installed

Satellite U200 - 10 H (PLUA0E) a maximum of 4 GB RAM expansion, 945GM chipset.
This model has 2 slots for memory and each unit of memory 2GB of suppor slot.

I have install 2 + 2 GB: BIOS correctly detect memory
Diagnosis Mode and OS, detected only 3, 2 GB :(

I know about 2 GB limit but can I change something (BIOS upgrade or LIKED) to change this limit?

Why the BIOS can detect 4GB?
Deadline is - what chipset?
Can I fix it and what I should do?

This is a really easy thing to explain. You are using a 32-bit version of Vista or XP, which can only, because of its use of architecture 3, 2 GB of ram maximum.
To use all of your 4 GB, you will need to install an operating system 64-bit, like Vista or if you dare a 64-bit version of XP.

BIOS can detect all the 4 GB because the hardware supports it, but windows or your tools diagnostic steps, due to limitations of 32 Bit OSs.

Get a 64-bit operating system, and you can use it.

  • Satellite A100 PSAA2A - BIOS recognize only 1 GB of RAM after upgrade

    Hello

    I have a Satellite A100 PSAA2A. RAM is up to 2GB (2 slots).
    Now, I have 256MB + 512 MB (Kingston KVR533D2/S4/512) total = 768 MB (Samsung 256 MB DDRII 533FSB).
    It works well

    I want to improve my RAM. I've got Kingston KTT533D2 / 1 G
    I have 512 MB + 1024 MB = 1.5 GB

    I removed 256 MB to 1 GB. Now she has 512 MB and 1024 MB
    But BIOS recognizes only 1 GB (Windows XP as well). I changed my slot machines, a different combination made - always 1 GB (not 1, 5 GB)

    I checked each memory separately 256 MB, 512 MB, 1024MB - works well, but combination of combination and 512 MB + 1024 MB 256 MB + 1024 MB do not work.

    I did a BIOS upgrade and set version 2.3

    Any ideas guys?

    Thank you.

    I m not sure but I think the problem are two different modules. They come from different manufacturers have different abilities.

    If you want to, or more than 1 GB RAM, use should use the same modules. At a time when prices are cheap.

    But you can also test the RAM with special tools like Memtest86:

  • Satellite A100-551 recognizes only 1 GB of RAM after upgrading memory

    Hello

    I just bought a memory of 1 GB of RAM to upgrade my Satellite 2 * 512 to 1 * 1024 + 1 * 512.
    The brand of memory is Crucial.

    Everywhere where I put my memory (1 GB in slot 1, 512 MB in the 2 slot or vice versa), my computer don't recognize only 1 GB.

    Some ideas on this concern?
    What I have to put the same size of memory in each slot, maybe?

    THX in advance for your help.

    Kind regards.

    If you only check this forum and search for RAM upgrade themes, you will see that the people who use essential modules reported on compatibility issues.
    If you want to upgrade to Ram successfully, please use the modules recommended Toshiba or Kingston.

    If you have to choose between price and compatibility compatibility and good work modules, you must choose. Compatible Toshiba DDR2 400/533 1 GB module followed the part number - PA3411U-1M1G.

    I have trouble about an upgrade of RAM for this laptop. The laptop was originally a Samsung 512 MB of RAM.

    I bought and installed 2 Kingstone SODIMM 1 GB Value Ram DDR2 PC2 4300 units compatible with the laptop, but

    in the BIOS, I see only 1 GB of RAM.
    I tested each RAM separately and they work very well. The problem is that when I install in my

    locations of the laptop, my BIOS sees no Ram.Instead 2 GB 2 GB, it shows only 1 GB. I updated my BIOS for more later

    version 1.70 (for XP), but the laptop continues to show only 1 GB.

    I tested the RAM separately:
    -inserted only 1 stick in the drive and the pc started ok showing 1 GB of RAM
    -then I inserted the same stick in another location and it also worked well showing 1 GB of RAM
    - then I checked another unit of the RAM in the same way and worked well
    -When I try to put 1 GB of Ram and the old 512 MB RAm the BIOS correctly showed the new value of 1.5 GB
    -i also checked the other 1 GB of ram and the old 512 MB of ram and showed good again in the Bios with the value of 1.5 GB
    - but when I tried to put the 2 ram set units to obtain the BIOS only detected 1 GB 2 GB.

    I think the problem is that the two s of RAM are not compatible, but it is not explained to me because use you two identical modules.

    In your case I return the RAM to the computer dealer and say the modules work together in your notebook, but your laptop definitely supports 2 GB of RAM.

    I think that there is no other way because you have updated your BIOS to the latest version.
    Here is the part number for RAM Toshiba compatible:
    1 GB OF DDR2 400/533 (PA3411U-1M1G)

  • Satellite L30-113 does not recognize the two modules DIMM RAM

    Hello

    I have a Toshiba laptop Satellite L30 113.
    It has 512 MB of RAM and therefore struggled to run Windows Vista, so I bought another 1 GB of RAM.
    It's DDR2 553 MHZ (PC4200.

    The problem I have is that the laptop does not recognize both DIMMs, i.e. the old 512 MB and the new 1 GB when they are in the whole PC. I tried the two DIMM individually in both slots and there is no problem, but when I install both the system sees just 1 GB. I tried the DIMMs around two ways but without success.

    Did I miss something?
    They should be the same size as in the bad old days?
    What is going on?

    Thank you

    Adam

    > I tried the two DIMM individually in both slots and there is no problem, but when I install both the system sees just 1 GB
    Seems that the two RAM modules are not completely compatible...
    I've read several times on these issues and to be honest it s are not uncommon

    I advise you to buy two identical RAM modules ad then to try again

    I'm afraid there is no other solution for your problem of m.

  • Satellite U200: Home WXP - installation of the other language

    I saw a good deal on a Toshiba Satellite U200 and want to buy, only problem is the Windows XP Home comes with, it is in French, and I want an English... OK, I have one English here, so I can activate it, but I was wondering if I can just install the English version and remove the French class. Do I have to re - install all drivers and stuff?
    If so, I can find them on the Internet from Toshiba site?

    Thanks in advance.
    Greetings, ' pimpin :)

    Hello

    If you want to use the Windows in English then you definitely install this OS in the English language.
    Then you have two choices. Either you want to use only a single OS on the HARD drive and install Windows in English on the existing French operating system partition you will create a second partition and install the English Windows as the second operating system.

    After the installation of the OS, you will need to install the drivers of Toshiba and utility in the right order if you want to use the features of Toshiba laptop together.

    The necessary drivers, you can find the Toshiba site

  • Satellite A110-294 does not recognize the wireless card

    Hello

    the question is:
    Why my Satellite A110-294 does not recognize the wireless card?

    I re - install Xp PRO with all the drivers.

    I have try all the drivers Wireless: Wlan intel + proset intel atheros wlan + wlesscmgr

    I don't understand, can you help me?

    Thank you
    André

    Hello

    To my knowledge, the A110-294 uses the Atheros WLan card and therefore the Atheros Wlan dirver should be the right one.

    You can find the latest driver for Atheros WLan here:
    http://APS2.toshiba-tro.de/WLAN/

    Just a question;
    You see the local network card in Device Manager? I mean, you should see an Ethernet controller or an unknown device in the network adapters
    The driver is missing, then the device must be marked with a yellow exclamation point

    I recently installed (clean) Windows 7 Ultimate 32 bit on my laptop. I have installed 1.5 GB but Windows will only recognize 1 GB. In the BIOS is shows 6 cents or so to base memory and 8 cents strange memory. I'm so confused.

    What I do need to update the BIOS and I can update the BIOS?
    Any help would be great.

    As it is, I had to run a 'mobilitymodder.net' hack to get the card to read different than just the Standard VGA adapter...

    Help, please
    Andrew

    Hey,.

    Normally, the BIOS should recognize 1.5 GB of RAM if the modules are working properly. Please check the BIOS again the amount of RAM is recognized.
    Updating the BIOS will not help you, this doesn t affect the amount of RAM.

    I think little of memory will be used for memory graph and other hardware components how much RAM is reconigzed in DirectX (start > run > dxdiag)?

  • Satellite A200-10W recognize only 3 GB instead of 4 GB of RAM

    2 years ago, I bought the laptop Toshiba A200-10w.
    He had 1 GB of memory installed (at the time, the seller said that ram can be expandable to 4 GB).

    Recently, I bought RAM 2x2gb modules.
    When I installed the modules I had to update the update of the BIOS-Windows X, to recognize all the ram installed, but during POST only 3071 MB of RAM is checked (even though the main BIOS screen lists that 4096 Mb is installed).

    Even if I use FreeBSD 64-bit operating system I can only access 3071 MB of RAM.
    Is there a solution to this problem?

    Hello

    To access the full 4 GB of RAM as the three components; Operating system and BIOS of the Chipset must support 4 GB of RAM.

    If one of these parts does not support the 4 GB of RAM then your laptop will not handle and will not recognize the full 4 GB of RAM.

    Check your chipset and look into the details to the Intel page.
    There, you can find an info if your chipset is capable of 4 GB.

    I have a Toshiba Satellite U200-115 model No.PLUA0E - 0970372N which ran from Windows XP Professional. Stupidly, I decided to reformat the hard disk to clean. When I got to use my original recovery disk I found that it was badly scratched and unusable. I just got a new recovery disk, but he installed Windows Vista not what the machine came with.

    It says "this copy of Windows is not genuine" and that the "product key is invalid for activation. I don't have a product key for Vista only for XP Professional!

    I noticed that on some computers laptops Toshiba, the screen refresh rate is fixed on 60 Hz.
    The screen refresh rate is not important on laptop screens.
    Matrix TFT is not such a thing as the refresh rate. It is not blinking.
    TFT as all other LCD screens do not refresh rate setting, only the reaction time.

  • Satellite A200-1CR does not recognize the module of RAM 2 GB

    Hello

    I have a problem with the extension of the RAM.
    I have the Satellite A200-1CR with 2 x 512 MB of RAM.

    Now, I bought 1 x 2 GB RAM (DDR2 PC2-5300 (667 MHz); PA3513S-1M2G) but the BIOS and Windows recognizes only 1 GB.
    When I add 1x512mo to the second slot, the system recognizes 1.5 GB of RAM.
    Where is the problem?

    What should I do to make it see 2 GB?

    Paula

    Hello

    I think the answer is very simple.
    Satellite A200-1CR can be upgraded up to 2 GB of RAM.
    This means that you can use max 1 GB of RAM in one slot
    You used 2 GB of RAM and this module does not seem to be compatible
    In my opinion if you want to use 2 GB of RAM then you can buy 2 x 1 GB RAM modules

  • Is there an automatic procedure to retrieve all the drivers on the Satellite U200?

    I have re-installed XP on my Satellite U200 and lost all drivers and settings. Is there an automatic procedure to retrieve all the? I'm a bit mazed by 52 varieties of the drivers available on the support web site.

    Thank you.

    You are going to use the Toshiba Recovery CD or will allow you to install all the drivers manually.
    I guess the recovery with XP CD is not available for this laptop and therefore only the manually installation is possible

  • How can I see the amount of cycles of battery on the Satellite U200-181?

    I have Satellite U200-181, and I use it hard, each. I want to be ready replace my battery, when he has 400 cycles.
    How can I see the amount of cycles of battery on my laptop?

    You shouldn't see this. You will see that the battery capacity goes down and will be empty shortly after. No one says that you will be able to use the 400 battery cycles only. You may be lucky and the battery will be more long service life.

    My Tecra M1 is about 4 years old and still works with the original battery.
