• Installed to 32 GB of RAM but only 16 GB usable

  I have an iMac 27 ", end of 2013 model. I am running Windows 7 Home Premium 64 bit on it via BootCamp.

  I ordered (4) 8 GB of RAM from Crucial.com and install myself.

  Now iMac says he sees the 32 GB but only 16 GB is usable. I have already confirmed on the Apple Support site that this computer can indeed be upgraded to 32 GB. What I'm doing wrong or have not yet done?

  All Ram modules have the same specifications?

  204-pin PC3-12800 (1600 MHz) DDR3 SO-DIMM

  It is very important.

  Did you leave the original Ram in and simply added, or have you put 4 new Ram modules that you suggest and take the original outside?

• I have 4 GB of RAM, but only 3.75 GB are usable/available: why?

  I bought a desktop computer Dell Inspiron 400 in 2010.

  It has a processor AMD Athlon 2650c installed with a captivity of memory RAM of 4 GB but only 3.75 GB is usable or available, why? Where's the other Go.25?

  There are a few possibilities.  If you use a 32-bit operating system, there is not enough bits of address (to use) more than this amount of memory, so the rest (le.25) is literally inaccessible to the system.

  If you have a 64 bit OS and it still shows, it is because your system is reserving some of them to be used for low level such as video memory system functions.

• I installed 6 GB of RAM, but only 2 GB can be used

  Hi I looked for an answer to my request, but I found the same answer everywhere and it does not

  I run Windows 7 64 bit and I have 6 GB of installed RAM (Yes in the system it says that its installed) BUT

  He said also only 2 GB of ram is usable out of that 6 GB?

  Now, my GPU (Asus geforce gtx 470) says in the manual it has 1 GB of memory dedicated, so that leaves 3 GB missing lol

  In my BIOS my PC says I have 2 GB of TOTAL ram? Now, it's an important goal. I have an Asus p7p55d-e pro motherboard. Any help as to how I can check if the ram IS working properly or how to make this usable ram?

  Thank you!

  What RAM do you use? Also update the BIOS, please. Remove the gain of RAM and put it back. Maybe it is not properly installed. "A programmer is just a tool that converts the caffeine in code" Deputy CLIP - http://www.winvistaside.de/

  Hello

  X 86 Windows will not be able to see more than 4 GB, so it will not work. Now, JUST try to 4 GB to see (and normally its usable is around 3.25 to 3.75 GB).  If you want to use more than 4 GB, you need 64-bit operating system.

  Kind regards.

• In Windows 7 has 4 GB of ram but only 2.75 gb usable

  I have
  Win7 32 bit os.
  AMD phenom II x 2 550 processor
  4 GB of ram

  but it shows only 2.75 GB usable.

  Why so much?

  A 32-bit operating system is not able to use more than 2.75 GB of RAM (maximum addressable memory is 2 * 32, which is about 2.75 gig). In order to use full 4 GB of RAM, you need a 64-bit operating system.

• ProBook 4720 s Windows 7: I have 4 GB of RAM but only 2.99 GB is usable

  Specifications for the ProBook s 4720 said memory maximum support is 8 GB, so of course material and the BIOS can support more than 4 GB.

  I just added 2 GB to the original 2 GB.  The computer properties is reported now only 2.99 GB usable.  I can understand if the chipset and BIOS has a limit of 4 GB.  Why is - what happens on my ProBook?

  I couldn't find anything in the BIOS, set up that could change that.

  Is all the same to recover the missing 1 GB?  Thank you.

  its because your shared video memory use. the embedded video processor uses a certain amount of memory in the computer for video output...

• Satellite Pro A120 - 2GM RAM but only 896 MB recognized

  Hello
  I have the same model and similar problem then would not start a new thread.

  I just removed the stick a 512 mb and replaced with 2 sticks of 1 GB, but when I check in system information it shows only 896 MB.
  This should be about 1 800 MB, I think.
  What I have to change all the settings so that it can recognize the two sticks?

  Dave W

  Hello

  There s no need to change the settings in order to recognize all the RAM.
  The BIOS should detect the two RAM modules automatically.

  In your case I suppose that a module of RAM was not recognized and therefore shows only 896 MB.
  The small part of RAM is located by the graphics card and is why it shows only 896 MB.

• Satellite L850-D2S - 8 GB of RAM but only 2.72 GB available

  D2S-L850 satellite PSKG8R-03S003RU. Windows 8. It's a 4 GB of RAM. In the 'system information' was written 4 (2.72 available) RAM. Set the bar for another 4 GB. He was 8 (2.72 available) RAM. Why only 2.72 available?

  How do you ensure to use more RAM? Sorry for bad translation.
  I am from Russia

  The laptop supports max 16 GB of RAM. So you should be able to use max RAM 2x8GB
  I think you should try this:

  1. press Windows + R key.
  2. then type MSCONFIG
  2. System Configuration window appears on the screen.
  3. click on the tab named "boot".
  4. click on "Advanced Options" and uncheck the box 'memory Maximum.
  5 reset

  I hope this helps, your comments would be appreciated

• Equium L20 with 256 MB of RAM but only 191 MB are available

  I was wondering if someone could explain what is happening with the RAM memory on my machine.

  It says it comes with 256 MB of DDR2 RAM. I can't run Norton antivirus to all pc games requiring a 256 MB of RAM as it keeps 'only 191 MB of RAM' available

  Can someone explain what is happening?

  Thank you very much

  Just reply:
  The laptop uses the shared video memory card.
  (Perhaps an ATI RADEON Xpress 200 M graphics card with available 32 MB to 128 MB.)
  Currently, the video graphics card sharing 65 MB of main memory. (256 MB 191 MB = 65 MB)

• 3.46 GB of usable ram but 8 GB installed

  Hi there im having a problem with my computer because its only letting me use 3.46 GB of ram instead of the full 8 GB I have installed can someone help me please?

  If your Windows 7 is a 32-bit edition, 3.46 GB is as good as it gets. To get the full benefit of 8 GB, you must run Windows 7 64 bit.

  If you do not have a Windows 7 64-bit installation disk, you can download an ISO

  Windows 7 Ultimate SP1 - U ISO

  English x 64: X 17 - 59465.iso

  Windows 7 Professional SP1 - U ISO

  English x 64: X 17 - 59186.iso

  Windows 7 Home Premium SP1 - U ISO

  English x 64: X 17 - 58997.iso

  and then to create a bootable DVD with this...  http://www.ImgBurn.com/

  Note that:

  1. You will need to back up all your things before we continue...
  2. Use one of the above, it will take a new installation, and you will need to install Windows 7 drivers from the manufacturer of the computer after the basic installation is complete if you want the best from your equipment. A
  3. You have used more than any additional software that has been registered originally before the installation...

• Satellite A100 - 750 PSAAR, 4 GB of installed RAM, 3 GB of usable RAM

  I just upgraded my Satellite A100-750 of 2x2gb 2x1GB RAM.
  The BIOS recognizes 4 GB RAM
  but the output of said BIOS then "spent 3 GB RAM system".

  My Windows 7 Pro 64 bit OS said it has 4 GB of RAM, but only 3 GB are used.

  How can I use all my 4 GB of RAM?

  It should not be an OS problem but maybe a one BIOS.
  I tried to update my BIOS (now system BIOS version 6.0).
  but without success.

  Any suggestion?
  Thank you very much in advance,
  Carlo

  Hello

  In order to use 4 GB RAM three different factors are important.

  (1) BIOS
  (2) chipset
  (3) OS

  You will be able to use 4 GB of RAM if these 3 parts provide support for 4 GB RAM.

  Win 7 64 bit is 4 GB of RAM, so you should check first the capable chipset.
  Check chipset in your laptop computer and research on the Intel page for details if 4 GB of RAM are supported.
  If 4 GB of RAM are supported by the chipset then the BIOS does not appear to provide support for 4 GB.

• C55-A-19N satellite: 4 GB of RAM installed but only 2.39 is usable

  Hello

  I have Toshiba satellite A-C55-19N with Windows 7 32 bit. It has 4 GB of memory installed, but only 2.39 is usable.

  BIOS is the latest.
  I can't find the option to change anywhere in the system.

  My desktop with core i5 - 2500K can see 3.29 GB to 4 GB of RAM, why toshiba can not see?

  32-bit systems (no matter if its Win 7) Win XP, Vista etc.) supports only 3.2 GB of RAM
  It is the 32-bit boundary.

  The other small part (300 MB roundabout) is shared by the graphics card.
  Therefore, the system displays only 2.39 GB RAM
