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

  I have

  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.

  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.

  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

• 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.

• 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...

  My PC running the 32-bit version or 64-bit Windows?

  http://Windows.Microsoft.com/en-us/Windows7/find-out-32-or-64-bit

  http://Windows.Microsoft.com/en-us/Windows7/installing-and-reinstalling-Windows-7

  Windows 7 64 bit comes in handy when you need to deal with at least 4 GB of RAM or more. Windows 7 32 bit can use up to 3.2 GB of RAM. Because the address space of memory is much larger for 64-bit Windows, this means that you need two times more memory than the 32-bit Windows to accomplish some of the same task, but you are able to do much more, you can have more apps open, do things like run a virus scan in the background it will affect the performance of your system. 64-bit Windows 7 is safer too, malicious code cannot easily infiltrate it, drivers are more reliable because they must be signed before it can work with 64 bit Windows 7.

  Regarding compatibility, you need device drivers 64-bit hardware devices, you may have. In addition, there is no 16-bit subsystem in Windows 7 64-bit, which means, your applications must be 32-bit only, not 16-bit Installer or programs uninstaller. Also, if you decide to switch to Windows 7 64 bit in the future, there is no way to upgrade from 32-bit Windows, clean install only.

• 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.

• 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/

• 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)

  Hello
