• memory 8 GB installed but usable only 3.48

  I have HP g7-1355dx notebook with Windows 7 64-bit operating system. I've increased the RAM to 4 GB to 8 GB.   The system says I have 8 GB memory installed but only 3.48 GB usable.  I am absolutely sure that I have 64-bit operating system and run msconfig and checked and unchecked the zone memory maximum.  I did a little research on google and did not understand what to do.

  Any help would be appreciated.

  Wade

  Thanks for the quick response.  After I posted my question I decided to spend the original 4 GB with the new 4 GB.  I don't know why, but everything is fine now.  Still, the system recognizes installed 8 GB but now 7,48 GB usable.   In retrospect I wished that I had tried this before you spend 10 + hours of research on the problem without success... even if making the switch seemed counterintuitive.  Hope this helps someone else.

• Why the system writes: installed 4 GB of ram, but usable only 3.6 GB of ram?

  3.6 GB is a very good number - much higher than most people's.

  All versions of Windows 32-bit client (not just XP/Vista/7/8) have a
  Address 4 GB of space (64-bit versions can use much more). It's the
  theoretical upper limit beyond which you cannot go.

  But you can't use the whole address space. Even if you have a
  Address space of 4 GB, you can only use around 3. 1 GB of RAM (and as I
  said, you do much better than that). This is because some of
  This space is used by the hardware and is not available for the operation
  system and applications. The amount you can
  use varies, depending on what hardware you have installed, but can
  range from as little as 2 GB to 3.5 GB. It's usually around
  3. 1 GB.

  Note that the hardware is using the space, not the real address
  The RAM itself. If you have a larger amount of RAM, the rest of the RAM
  goes unused because there is no address to map space to.

• 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

  Your system is an older model of HP and has a built in graphics that partaking of the RAM. That's why your RAM is showing as he shows.

  Hello chillinbro07,

  Your memory is not listed.  Let me suggest to do a clean install with your 4gig of RAM, then after installing the operating system, add the extra 4gig.  See if it works.

  I read somewhere that someone had success in re-sitting their CPU on the motherboard.  If you are comfortable doing this, you can try it.  Otherwise, I would do the same type of memory that they have been reported as compatible for their mother.

  Kind regards

• Satellite A100: 2 GB of RAM installed, but Windows displays only 1.99 GB

  Hello everyone again

  I've recently updated the ram in my A100-583 from 1 GB to 2 GB.
  However, although the computer does not seem to run much faster, when I look at the properties of the system in the main general tab, it's only show that there is 1.99 GB it is a problem with the Ram, or is it just a glich with the System Properties window.

  All other system checks indicate that there are 2 GB in the comp... The ram I installed is corsair ddr2 sodimm 667 mhz/pc25300.
  {Any help with this will be appreciated thanks in advance: 8}

  I don t think that it is a problem of memory modules (RAM live).
  What is the BIOS reports?

  Still that memory could be shared with the GPU (graphics card), and the windows OS also uses some of the memory

  Don t you worry and there is everything ok ;)

• RAM INSTALLED BUT NOT START THE COMPUTER

  MR. PRESIDENT IS RESPECTED,

  I HAVE G6-2312AX HP PAVILION NOTEBOOK COMPUTER. WINDOWS 8 IS INSTALLED IN. 4 GB OF RAM ALREADY THERE. NOW, I WANT TO ADD 4 GB MORE. I BOUGHT 4 GB OF RAM DDR3 1600 MHZ AND TRIED TO INSTALL IT. BUT THE COMPUTER DOES NOT. KINDLY TELL WHAT TO DO. JAI HIND

  It seems that if you did not put in a pair of identical bars or has not used the memry guaranteed compatible modules. You cannot use the module that was already there, unless you add is identical in every respect.

  Use only guarantee modules in identical pairs if you want your upgrade memory to work right the first time.

• Satellite L650 - 15G - 4 GB installed but usable 3.87 GB

  Hello

  I hope someone out there can help me out. I bought the laptop mentioned above over the weekend. Memory std for this machine configuration is 3 GB of RAM, noticing that he had x 64 version of Windows, I went out and bought a 2 GB to bump up to 4 GB memory module. The machine, set up and checked the memory in system properties, it says 4 GB installed 3.87 GB usable. On further investigation, I found that 137MB of RAM was material reserved.

  Is there anyway that I can get this comprehensive performance 4 GB RAM and back?

  Help, please.

  Hello

  The small part of the main memory is locked by the graphics card.
  GPU shares a small amount of RAM main. This is controlled automatically by driver graphics card, so you cannot modify it manually.

  Where are you seeing the 3.29 "usable"?  It would be fair that the rest is in fast cache.

  Hello

  I suggest you try the procedure described in the link and check.

  Usable memory may be less than the memory installed on Windows 7 computers
  http://support.Microsoft.com/kb/978610

  Note: BIOS change / semiconductor (CMOS) to complementary metal oxide settings can cause serious problems that may prevent your computer from starting properly.

• Windows says 6 GB usable only 4 GB of ram

  My bios says I have 6 GB of Ram installed and when I checked my ram under windows he says 6 GB usable I use windows 7 Home premium 64-bit only 4 GB of ram. Is there a setting to make it work with 6 GB of ram

  Hi Keefy1,
   
  On a computer that is running a 64-bit Windows 7 version, usable memory may be less than the installed memory (RAM).
  
  This is expected behavior on computers that are running Windows 7. The reduction in available system memory depends on the configuration of the following:
  1. the devices that are installed in the computer and on the memory reserved by these devices
  2. the ability of the motherboard to manage memory
  3. the BIOS version and settings
  4. other system settings
   
  To see how it is allocated the memory installed in Windows 7, follow these steps:
  1. click on start, type in the box resource monitor search programs and files, and then click Resource Monitor in the list programs.
  2. click on the memory tab and then view the physical memory section on the bottom of the page.
   
  There are several additional situations that could cause the usable RAM is less than expected. These issues and possible solutions are listed in this article: http://support.microsoft.com/kb/978610
   
  I hope this helps.
   
  Kind regards
