Upgrade memory up to 8 GB shows only 3.48 GB available

HP Pavilion notebook g7

Windows 7 Pro sp1

Problem: installed 8 GB of memory. System information shows all that 8 GB by said only 3.48 GB available for windows.  How can I get Windows to access the memory.

Thank you in advance, I have this problem having been watching for weeks.

found the solution.  You must install the same memory manufacturers in both slots.  I installed the new memory all the same company and I have finally the 8 GB.

  • After the memory update satellite L20-206 shows only 1 GB

    Hello, could someone tell me:
    Ive had 2 modules of 512 RAM (Samsung) & 256 Hynix. After that I decided to install 1024 Mb (Crucial (Micron), Bios, and OS doest see 256 MB module - 1024 MB only.

    The same photo that I install 1024 MB + 512 MB. I already flashed with the new Bios - it did not help.
    But the utillity CPU - Z in Windows recongnizes modules 2 in both cases?

    P.S. Should I install the same module as my Crucial (Micron) or my laptop supports no more than 1 GB?

    Now, using a 1024 module, well enough, but maybe in the future, I would like to have more.

    Well, it's very strange because the L20-206 could be upgraded to 2 GB max memory!
    In this case, you can use the modules of memory 2x1024Mo!

    The laptop should recognize two modules installed! But maybe the two modules aren't compatible? In any case, I advise to use the same modules with the same specifications.
    I found a few modules recommended by Toshiba. So maybe you want to use these:
    512 MB DDR2-400/533 (PA3412U - 1 M 51)
    1 GB OF DDR2 400/533 (PA3411U-1M1G)

    {color: #000000} Dear Forum Toshiba,

    I own a Toshiba Satellite A110-103 (PSABE6) bought in 2006 of the Belgium.
    I have trouble about an upgrade of RAM for this laptop. The laptop was originally a Samsung 512 MB of RAM.
    I tried to upgrade the RAM to its maximum capaity supported 2 GB.
    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.

    Here's the description detailed 1 GB modules that I try to install:

    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)

    Hello

    That means the POST (power on self-test) screen appears; 4 GB or 8 GB of RAM?
    All memory is recognized in the BIOS?
    If so, then the memory has been recognized correctly and Windows 7 64-bit should be able to use all 8 GB of RAM.

  • Qosmio G30-10 b: BIOS shows only 3328 MB instead of 4 GB of memory

    I've updated by laptop 4 GB of memory. The reports correctly that 4096 MB in the BIOS screen. When you start however it shows only as 3328 MB and that's obviously what Vista reports. (I know that 32-bit Windows systems probably will not see any memory, but probably checking the BIOS boot should display correctly).

    Last update of the BIOS was done - running on v3.50

    Post edited by: gerhards

    If the BIOS recognizes all 4 MB of memory, so I don't think it could have a bad influence on the performance of the laptop.
    As you already suggested the whole 4 MB can be recognized by the operating system 32-bit Windows due to the limitation of the system.

    Recommend checking this Toshiba document:
    http://support.toshiba-tro.de/KB0/TSB7601WE0007R01.htm

    Please check the part called "(detailed) resolution:
    I put the memory 2x2gb bars in my computer laptop and the BIOS and the operating system is worth about 3 GB
    So BIOS might watch also a value of bad memory

  • Satellite Pro A200 - shows only 3 GB instead of 4 GB of RAM

    Hello

    2 years ago I had a Satellite Pro A200 as a professional laptop and it works with XP SP2, later with SP3. With 2 GB, it shows 2 GB memory in Windows - and I know it's a Radeon 7500 with 256 MB memory graphics individual, and there is no shared memory.

    I upgraded to 4 GB, but Windows shows exactly 3 GB. BIOS shows 4 GB and ATI system monitor shows 4 GB. I know that 4 GB is not possible under XP 32-bit, only on Windows 2003 R2 32 bit or Vista - but on desktop systems, I've seen values between 3.3 and 3.7 GB.

    So, where's the memory? It looks like a bug - the chips of memory have two 2 GB I checked this. Because it's a company laptop I can not just switch to 64-bit XP :-(

    There's no option in the BIOS - first I thought that it is the graphics card, but mine has independent graphics with own memory so that the computer comes up with MB 2048 or 4096 after the upgrade.

    Shared memory would show about 1900 MB of RAM for the operating system as my private EEEpc.

    Hi shadowmaster_1,

    > I know that 4 GB is not possible under XP 32 bit
    Then why do you ask this question here if you already know? Moreover, it s not a limitation in XP, it s a material limitation on all 32-bit systems

    > only on Windows 2003 R2 32 bit or Vista
    And who says that Windows 2003 or Vista can use 4 GB? Okay, there's an update for Vista where 4 GB correct displayed in system properties, but that doesn't make no difference. Vista 32 bit peut t use all of 4GB, it s only cosmetic improvements! ;)

    > So where is memory?
    Memory is installed on your computer, but can t be used complelty with a 32 bit OS.

    At the end of the story: If you want to use 4 GB, you need to install a 64 bit OS. On all the 32 bit OS, you can use only upward to ~3.2GB RAM!

  • HP ENVY Sleekbook 4-1000en: upgrading memory on ENVY 4-1000en

    Hello

    Since I have some basic computer knowledge, but I want to be sure before you go for it, I need your advice.

    I have a HP ENVY Sleekbook 4-1000en and I have recently upgraded to HDD and the OS.

    I think the upgrade of RAM have, as far as I know that you need 2 memories of the same type, so I guess I can't buy an another 4 GB right?

    Do I need 2 x 4 GB of DDR3 memory, of the same type to make it work? For example they would work very well

    http://www.corsair.com/en/vengeance-8gb-high-performance-sodimm-memory-upgrade-kit-cmsx8gx3m2a1600c9 ?

    Finally the upgrade memory requires any other configuration after plugin in? Is a format for example?

    Thanks for your time.

    Hello

    The following link shows the specifications of your computer:

    http://support.HP.com/us-en/document/c03362810

    It has 4 GB of RAM now. The question is 4 GB in a dwelling or in the two slots (2 + 2).

    b in the case of a home, you can just buy another 4GB with SAME part/characteristics of the EXISTING RAM and install in the second slot.

    (b) if in 2 slots (IE 2 + 2), then throw them both and buy 2 new sticks 4 GB each. Agin use even care.

    You don't need to format RAM. Moreover, we have only to format HDD/SSD but not RAM. And Yes, push in the two slots must be same same specs even marks to be able to get all the benefits.

    Kind regards.

  • upgrade memory 2540p

    • But when I take the cover on the back, I can only find a single SODIM 2 GB module and on You Tube, they show only one.

    So, how to upgrade the memory up to 8 GB, which is what HP support site says that the 2540p can take?

    Thank you very much

    Hello

    Second memory is hidden under the keyboard. First, you must remove the keyboard, and then you will need to unscrew the screw that holds the shield of memory. Lift the right edge of the shield of memory and slide it to the right until the tabs on the left edge of the ecu memory are free of their slots on the top of the cover and remove.
    Now, you will see the second memory module.

    Note:

    Don't forget to unplug the AC adapter and the battery before you follow these steps.

  • Satellite L100 113 starts slowly after upgrade memory

    Hello

    Toshiba Satellite L100 113 PSLA3E-02401JRU starts slowly after upgrade memory with Kingston KTT533D2-512 (512 MB) of memory.
    When I press the 'power' button, it flashes, starts the fans and HARD drive several times. Then it shows BIOS start messages by memory full 768 MB and starts Windows XP without a problem.
    This behavior is noticed only after "shut down."
    It does not happen with "restart".
    What can I do to eliminate this long "attempts" to start my laptop computer?

    Thank you
    Novomir Kovalenko

    Hello

    This problem appears before upgrade memory?
    Have you used exactly the same memory modules?
    If this isn't the case, then perhaps there are a few compatibility issues.

    Usually, after the insertion of the modules you must enter the BIOS and then save the settings. Please it and eventually the laptop will start without any problems.

  • Upgrade memory on R7-572-6423

    I have not seen a thread here on the new model, so I thought I would ask here.  The published specifications state that the laptop is expandable up to 16 GB of ram.  However, I run CPU - Z to check the installed memory.  It is said there are two sticks of Kingston Value Ram of 4 GB installed in banks 1 and 3.  It shows 2 and 4 banks in a vacuum.

    Now I see that there are only 8 GB modules available on the market.  Could not upgrade the laptop to 24 or 32 GB of ram?

    Also, as I have a screwdriver torx on order I could not open the system remains to be verified.  There are really 4 available memory slots?  I see no mention of the previous model had soldered chips.


  • Upgrade memory Acer Aspire 5552

    Hello

    I just upgraded to 4 GB of RAM 8 GB on my Aspire 5552. But when I display the properties of the system that it has detected 8.00 GB of RAM, but only 3.74 GB is used. How can I activate the rest of the extra memory I added?

    The RAM I installed is accompanied by 8 GB of PC3 - 12800 DDR3 - 1600 RAM, consisting of 2 x 4 GB SODIMM laptop computer Ramaxel.
    The RAM in BIOS is showing only 8192 MB total memory with 256 MB of video memory.

    Acer Tech support advised the following:

    1. click on start, type msconfig in the search programs and files, and then click msconfig in the list programs.

    2. in the System Configuration window, click Advanced on the start tab.

    3 clear the maximum memory check box, and then click OK.

    4 restart the computer.

    When I checked msconfig memory Maximum option was already unchecked. I tried to check (this is the value of 8192) and reboot, but no change then I unchecked and restarted again, but still only 3.74 GB are available.

    Acer technical support are now run out of ideas. Does anyone have any suggestions?

    I found the answer...

    "" in the start menu > msconfig > boot > advanced > make sure number of cores is 2 you have a dual core processor ' "

    I don't know if it was a simple thing that it was assumed that I already knew that, but I didn't and now I do, and I 7.74 GB of memory can be used.
