BIOS and Windows 64 bit 8.1 does not see rM 8 GB

Buy Acer E5 - 572G NX. MQ0EL.005.

It has 4 GB of RAM (Samsung 12800 1600 mhz) then bought a bar - Crucial 4 GB DDR3 PC3 - 12800 CL11 SO - DIMM CT51264BF160BJ.

Place it in the second slot.

Result - BIOS shows only 4 GB of RAM and Windows shows same 4 GB RAM (something aroung 3.8 GB)

Tried to replace the second stick of ram but same result.

Any ideas what's happening?

Tried to run laptop with only Crucial working stick - BIOS 4 GB

Then tried to place again noticed two poles that stick in second slot is not placed correctly (pins were visible), place it with more force, so that the pins are not visible and now it works.

Once in the BIOS and Windows - 8 GB of RAM.

Thanks, IronFly.

    I needed a 32-bit Windows 7 for my client of the hotel lock software installation, unfortunately, HP distributor misled me into buying 64-bit instead of 32 bit.
    The software does not run on the 64-bit and 32-bit and the Distributor is unwilling to change the system for me.

  • After that update of windows 64 bit system Firefox does not start

    I've updated to IE 10 and it should be updated to complete. My preference is Firefox, but it does not start and produces an error box telling me that Firefox could not start, it also sends you a report of failure.
    It happened in a previous windows update and to reolve that I go back to an earlier era. I don't want to do that this time, I want to use 10 IE and Firefox. If you are unable to solve this I have to use IE 10, it is so much faster now.

    Yes thanks - please start firefox in safe mode (by pressing the shift key, while it launches) and go to firefox > options > advanced > general & disable hardware acceleration.

  • Satellite U300 PSU30E - 32 bit WIn XP does not see 4 GB of RAM

    Hello

    I have two qustions about my U300.

    1. I have a 32-bit, XP Pro sp3 and 4 GB of ram. _PAE is enabeld_, Bios sees the 4gig to start, howerver XP does not work!
    What I read I should at least see 3.1 or 3.3 GB of ram, but no, I self 2.99.
    OK, so the video has borrowed the 256MB ram, but still why I can't get more ram memory?

    2. How do the video use not 256 MB but 358 MB (no option in the bios to do)

    I do not wish to use XP64 and Vista therefore suggests that it

    Thank you for the support

    Hello

    The operating system 32-bit Win no matter if it s Vista or XP supports max 3.2 GB RAM
    The operating system can show a smaller RAM value, because the small part of RAM would be assigned to the memory of the graphics card.
    I think that your laptop was equipped with GPU Intel GM965.

    It supports memory system shared and own (128 MB) of video memory.
    The shared system memory depends on main memory.
    Using 1 GB main memory = 123 MB Shared System Memory (GPU)
    To the help of 2 GB memory main = 230 MB Shared System Memory (GPU)

    Then system memory = total available graphics memory shared + video memory system
    You have total 358MB memory (230 MB + 128 MB) graphic card

    3.2 GB 358 MB = 2.9 GB ;)

  • I downloaded DNG Converter 8.7 and as a standalone application, he does not see the RAW files of my 7 5 d Mark 2.

    I don't want to spend 11 items yet.

    When I got my 60 d, I had to install the DNG Converter and after a few uses, 11 elements began to see also.

    On a 64 bit Win7 PC.

    In the how to video I've seen that all show them the files in the folder selected.

    I just tried to convert without no files appear and he says that he has found and is now converting it to DNG.

    YES!

    Simply by selecting the folder was sufficient, does not need to open or to see the files.

    Weird, different works than when I had my 60 d.

    Thank you very much!

  • option "restore tabs and windows since the last time"-does not work!

    The absence of "tabs" can be solved (by saving pages in the bookmarks)- but I have found no solution to remember open windows. Are there plans to replace this (fantastic!) feature in Firefox4, or how do I go back to an older version of Firefox?

    It is possible that there is a problem with the sessionstore.js and sessionstore.bak files in the profile folder

    Delete sessionstore.js and sessionstore.bak in the profile folder

    • Help > troubleshooting information > profile directory: opens showing the file

    If you see files sessionstore-# .js with a number in the left part of the name as sessionstore - 1.js then delete those as well.

    Delete sessionstore.js will cause App Tabs and groups of tabs to get lost, so you'll have to create them again (note).

    See:

    Start Firefox in Firefox to solve the issues in Safe Mode to check if one of the extensions of the origin of the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > appearance/themes).

  • Try to install Indiana Jones and the infernal Machine, Windows (8 / ME) compatibility mode does not

    I try to install Indian Jones and the Doomsday Machine on my computer.
    I tried using the compatibility mode for windows 98 / ME, but it does not work. When I run the program splash arrives, but when I click on install it closes then nothing happens. There are no errors.
    I am running Windows 7 64 bit.
    Also I install the original CD, and it has worked before in older computers (running Win 98 of course).
    Any help would be appreciated.

    The game should run fine under Win7 64 bit. The problem is that the installer is only 16 bit and is no longer supported in Windows. Just use a different Setup program. Try www.markusegger.at. I'm running the Doomsday Machine, Alliance Xwing, Xwing v's Tiefighter, and Grim fandango all on 64 bit Win7 all using custom Setup programs.

    I also used the original X-wing, Tie-fighter and fate of Atlantis via Dosbox.

  • I have a Windows XP Home Edition, which does not list if it's 32-bit or 64-bit

    I have an OEM Windows XP Home Edition, which does not list if it's 32-bit or 64-bit. How do I know what

    To check if your XP operating system is 64-bit, you only have to right click on "My computer" and select 'Properties' to display 'system properties '.   If your XP operating system is XP Professional 64-bit, 64-bit will be indicated in the information displayed in the general tab.  However, XP 32 bit operating systems won't have 32-bit, there is no information about this particular point at all.  The XP Home Edition will be 32-bit, but this information does not appear.  XP Professional, however, can be either 32-bit or 64-bit.  If it is 64-bit, it will be indicated on the general tab of the system properties. However, if it is XP Professional 32-bit, nothing is there to indicate that the operating system is 32-bit.

    Vista and Windows 7, unlike XP, OS will indicate if they are 32-bit or 64-bit.
