8 GB of RAM shows that only 2.85 GB usable

Dear team

My 32-bit Windows 7 system shows only 2.85 GB usable out of 8 GB of RAM in the system properties. Is there a problem with my PC. Help, please.

No, there is no problem, other than your lost money by buying
more than 4 GB.

All versions of Windows 32-bit client (XP/Vista/7 not only) have a 4GB
address 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. It's
because some of the space is used by the hardware and is not available for
operating 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
GB 3.1. you are a little below this average.

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

  • help help... ESX host shows that only ANSWERS DO NOT

    Hello

    I have the ESX host, who said State says "NOT RESPONDING" status virtual Center, but the host's who responded and I am able to connect to the console using PuTTY... Can someone help me what could be the problem to show the status as no ANSWERS DO NOT... I do not see that error correct logs in the logs events and... The virtual machine that is hosted on the ESX host also works very well and im able to RDP to it with all the problems but in VM, it shows as disconnected...

    ASK YOU TO HELP ME QUICKLY BECAUSE IT IS IN THE PRODUCTION...

    Hey Shashi,

    If the ESX host is unresponsive defeated VC if you can connect to the host ESX via VI Client, if yes, then the service pass works very well and you need to troubleshoot the service virtual Center on the esx host agent. You many consider them raise all initially with order # service vmware-vpxa restart

    If you are unable to connect to the ESX host using VI Client, restart the service spend using service # mgmt - vmware restart and check the logs # tail f /var/log/vmware/hostd.log check for errors/progress.

    Also look at kb.vmware.com for that matter and you'll find some articles that may help you solve problems.

    All the best

  • 8 GB of RAM is installed, only 7.88 GB usable

    So I when I load my computer and look at my control panel, I discovered in the ram installed it says that 8 GB is installed, but only 7.88 GB is used. Anyone know what this means? Help would be greatly appreciated! : D

    Johnny

    This is a minimum and normal (you never know even it is absent).  It is probably be used for shared video memory.

  • Since upgrading my ram installed shows 4 gb but says now only 2.93 GB usable why?

    Since I've upgraded to Windows 7 my ram poster now only 2.93 GB usable of my 4 GB.  Why would it be?  And that would be why my system seems slower since upgrade?  The performance is not as fast it was before Vista.  I am more than a little confused!  Why it does not use the full 4 GB?  Only just noticed this, so if someone wouldn't mind to tell me if there is problem I would be very grateful, I'm sure it was something before the 3 upgrade!

    Hi Linda,.

    There is actually a very technical reason for what you see, but basically it's because you're using a 32-BIT operating system.  If you use a 64-BIT operating system you would not see the problem.

    If you are interested, this post does a good job of explaining it is http://blogs.msdn.com/hiltonl/archive/2007/04/13/the-3gb-not-4gb-ram-problem.aspx , but basically, it's down to the way that the operating system uses the memory and how it spread what you can and cannot use.

    Long story short, that if you stay with 32 BIT, you're stuck with this...

    Hope this helps,
    Jon

  • Memory of DM1 showing only 3.6 GB usable

    I just bought the Pavilion DM1 Notebook.  There the chip AMD 450 with 4 GB of memory running with Windows 7 - 64 bit (according to the control panel)

    It shows that only 3.6 GB of memory is usable.  I'm planning to switch to 8 GB but not if it is not addressable.  Am I missing something?

    It's logical. Thanks for the info.

  • Satellite Pro A60 - Windows XP shows / use only a part of RAM available

    Hello guys!

    I am facing strange problems with one of my two A60s. I just upgraded two of them with 1024 MB of RAM the same. One works perfectly, but the other will show me only 410 MBs in Windows. The BIOS indicates the correct size. I changed the RAM from one to the other, but this strange error is always present. The version of the BIOS has been updated to 1.90 and has Windows XP SP2.

    Do you have any suggestions or ideas? Is there an easy way to put the management of RAM in Windows?

    Thank you in advance!

    Ralf

    It s very strange.
    I found that an additional Satellite Pro A60 info has been delivered with a different hardware configuration.
    Some A60 Pro comes with an internal memory of 512 MB and others with only 256 MB internal memory.
    In addition, the internal memory modules cannot be deleted and there is only one slot for memory upgrade.

    But I put t know why the OS shows only 410 MB

    Oh, I forgot to mention that the graphics card, also use the part of the main memory and, therefore, the operating system of shared memory could indicates a value of different memory.

  • Control Panel shows that 4 GB of RAM, but product specs say I should have 8GB

    My HP Pavilion Elite HPE-250f desktop computer is supposed to get 8 GB of the RAM factory installed, but the control panel shows only 4 GB. When I run the diagnostic with the Support Assistant software it says that everything is working well, but also shows that 4 GB of RAM. I've had the computer for several months and the warranty just expired. In the past, I noticed it says 4 GB and thought that I should have bought a computer with only 4 GB, but it has always seemed strange to me. I looked towards the top of the record online and it says the HPE-250f has of 8 GB, and it also says 8 GB on the box in which it came. I didn't do any changes to the computer and never open the Cabinet. I hesitate to open the cupboard, but do not feel I should have to pay a lot of money to understand this.

    It took me a few tries - and months of frustration - but I solved the problem by carefully removing the memory cards, clean gently slots and cards and firmly the resettlement of the cards. It's been several months now, but the memory has been resolved. I had serious problems, as it is stated in this thread, with a catastrophic failure of the graphics card and HARD disk failure. I read on several posts that this particular graphics card was problematic, so I've upgraded to a Radeon HD 7700 series. I got the Core edition, which has 2 GB of memory defect to 1 GB. No problem since.

    In case of hard drive failure, it was a disaster! I replaced the HARD drive of 1 TB with a 512 GB SSD, but it kept the infection by a rootkit that I couldn't clean up. I tried cleaners virus and rootkit of several software companies with no joy. Not even the first products like Kaspersky, McAfee, Sophos, BitDefender and other companies. I reformatted the drive several times, but the hook came back in return. Finally, I brought the computer to a friend who is a computer SCIENCE professional. The rootkit probably lies in the commercial cloning software (Acronis True Image HD) that came with the SSD, it said. We loaded the operating system without using Acronis and have not had any problems since! I've also installed a WD Blue 1 TB HDD and rebuilt directories so that all libraries (Documents, photos, videos, etc.) are on the disk hard while the system is installed on the solid state drive. The upgrades were worth every penny! Now, my desktop HP 5 years computer works very well and the performance is very good even by today's standards. Boot times are much faster, too.

  • Display the source shows not only HTML, but also external JS and displayed in a format that is unorganized, how is?

    When I use the view source feature, the pane shows not only the HTML code, but it sticks in all Javascripts that are in an external file. In addition to this all dashes went making it virtually unreadable.

    I have this problem with each monosite, I try to view the source of the. I turned in and uninstalled all add-ons. Starts in safe mode. But nothing seems to work. I got this in firefox 3.6 and upgraded to 4 it would fix, but is not hope.

    It's strange. How about trying to reset all preferences of view_source to their default values.

    Talk openly about: config (type or paste Subject: config to the address bar and press enter)

    In the filter box, type or paste view_s

    When preferences are displayed, do a right click and Reset those appearing in "BOLD" to return to their default values.

    A little luck?

    Edit: Oops, for Mac, read 'right click' like what you normally do to display a context menu.

You people need get the bugs out of your cloud services.
