How can I increase my usable RAM to 4 GB under Windows 7-32 bit?

I have a laptop (Acer 5741 G) with 4 GB of RAM. I run Windows 7 32-bit

> Control Panel > system shows that: installed Memory (RAM) 4.00 GB (2.53 GB usable).

I found a few fixes for Windows 7 and applied to my system and now it shows this: installed Memory (RAM) 4.00 GB(3.87 GB usable)

I want to know is there a solution for 4.00 GB usable in Windows 7 32 bit?

my graphics card is a Geforce GT 320 M with 1024 MB of dedicated RAM (No part).
Also, you can check my laptop specs: Acer 5741 G

Link to the patch file: http://www.tarfandestan.com/files/Patch-3-Windows-Vista-and-7.zip

Windows 7 32-bit is hardcoded only address 4 GB of TOTAL memory. If you have 4 GB of RAM and 1 GB of video RAM, your video card gets 1 GB which means now Windows has only 3 GB of memory left to address (even if you have 4 GB of free RAM). The other 0,47 GB is probably reserved for other hardware components (or buffer just as your reserved chipset). You can actually dig into the Device Manager and (with a little math) understand exactly the amount of memory is reserved for each component. Mark Russinovich has a very detailed and technical article is here: http://blogs.technet.com/b/markrussinovich/archive/2008/07/21/3092070.aspx

EAP is a feature that allows to address more than 4 GB of memory with 32 - bit. I * think * Win7 32-bit installs the core EAP (ntkrnlpa.exe and ntkrpamp.exe in c:\windows\system32) because it has other features for newer processors, but even the PAE-enabled kernel is still hardcoded to a 4 GB max memory addressable (http://en.wikipedia.org/wiki/Physical_Address_Extension#Microsoft_Windows). So I would say that the patch is trying to hack in and remove the 4 GB limit so that you can fully use EAP to address more than 4 GB. Aside from possibly violate the windows license agreement, you won't see any problems. Or you might eventually see some of the problems that Mark Russinovich describes as possible when the client systems use EAP for > 4 GB:

What they find is that many systems would crash, hang or be initialized because some device drivers, usually those for video and audio devices that are found generally on clients, but no servers, no were not programmed to wait physics treats more than 4 GB. Thus, the drivers truncated such addresses, having for result of memory corruptions and the side effects of corruption. Server systems generally have more generic devices and with drivers simpler and more stable, and therefore did not usually surface these problems. The problematic client driver ecosystem led to the decision for client SKUS to ignore physical memory that lies beyond 4 GB, even though they can theoretically solve.

    You can do this in two ways:
    ePrint printer (set up an email from the printer and send a document to the Android)
    * Use the HP ePrint home & Biz app that allows you to print directly to the printer of the Android

    In both cases, the officejet 8600 should be connected to your network wirelessly or through ethernet. To start using home & Biz it android should be connected to the same wireless network that the printer is working correctly.

  • How can I download for my sony dcr-dvd403 pmb to windows vista 36 bit

    looking for software for downaloda pmb for windows vista for sony dcr dvd403 handycam

    looking for software for downaloda pmb for windows vista for sony dcr dvd403 handycam

    You have Windows Vista 32-bit and a Sony DCR-DVD403 with LCD 2.7 "...

    According to the Windows Vista for Sony DCR-DVD403 Compatibility Center the device itself is compatible without any intervention on your part.  Support for any third party hardware or software is always from the hardware manufacturer or software.  It is their place to ensure that their hardware and software are compatible with the operating systems their customers use (or not to do - put an end to their support for said product and basically stating that produced a legacy package/device).

    Visit Sony support web page and put in your camera model after you have selected the option for downloads, it takes a place where you can select various downloads.  Simply choose 'Windows Vista' in the menu drop-down "Select an Operating System.  Then it expans show several possible downloads to support this device in Windows Vista, including updates of Picture Motion Browser and Picture Package Sony feeding with their products.  Here are a few updates - so you will need to have a version already installed.

    Notes for the Motion Picture Browser declares, "this utility updates PMB versions 1.1 to 5.8.01 and Cyber-shot Viewer version 1.0, PMB version 5.8.02..."- so I think it is reasonable to assume that, as long as you have an installed version (from the CD that came with your camera), you can use this update to bring it up to State fully patched.  Sony offers a link if you need to buy replacement CD for those that you should have received with your product.  Wow - 30 USD - they are proud of their software.  You may have more luck that many others in the research that a download legitimate to PMB is that you do not have your original CD...

  • How can I increase the video RAM on Satellite 1800?

    I want to increase the ram video shared in (Trident cyberblade Ai1 vga) from 8 MB to 16 or 32 MB. My laptop is Satellite 1800-804. I'm not able to see the configuration of the BIOS for this module.

    Can anyone help?

    Remond

    Hmm, maybe I m wrong but as far as I know this laptop supports only 8 sheared MB memory graphics card. I did not found anything about 32 MB.
    In any case, if the BIOS has no option for memory sheared increasing so be it s is not possible or you should check the properties of the graphics card of the art.
    There, you should check the performance tab.

    But as I said above, it of possible that the graphics card is supported only 8MB

  • How can I increase the size of partitioned 'Recovery' drive in Windows 8?

    I need to update my windows 8 to 8.1 in order to upgrade to Windows 10. The "recovery" partitioned D drive doesn't have enough space for the upgrade. Is there a FREE way to increase space partitioned drive?

    UPDATE: I GOT IT!

    I have shrunk the drive C to unallocated space of 10 GB and used free software EaseUS to increase the size of the disk D (I couldn't increase using windows).

    If your configuration is set with the partitions in a certain order or Setup, it can be moved using this tool, so you should come back to something like ZigZag3143 (Windows devices & for IT Pro MS - MVP) suggested.  Or another option is to save what concerns you, format the drive and reinstall everything fresh (it may be too much for you, but it is an option).

  • How can I recover pictures that seem to be lost under Windows XP? This happened after turning the images.

    Used Windows XP & rotated images. Now can not display. Tried to cancel. Without execution of McAfee. Tried the unhide. Nothing. Please, I beg you. Whatever it is. Photos not on PC, using the SD card in the converter via the USB port.

    Oh... OK, a card reader... Thanks for the clarification.

    Maybe you can recover photos from the SD card.

  • How can I get Firefox to load the "Background" images in Windows 7 (32-bit)? They will not load in Windows 7 Professional but when I installed Firefox it will load into XP Virtual console. How to load properly in the normal window of Windows 7?

    I have a laptop Toshiba Intel Core i7 CPU Q740 @1. 73 GHz 1.73 GHz, 4.00 GB RAM 32-bit operating system

    I noticed the problem after installing Firefox 4.0.1 but uninstalling and reinstalling found it was also a problem with the previous version.

    There is no boxes displayed on this screen, but on my XP desktop, they are displayed. I have two open so I know where to type.

    I installed Firefox on the virtual console XP on this machine and it worked fine, but not with Windows 7.

    None of the posted similar questions on this forum suggestions worked.

    Make sure that allow you pages to choose their colors and you have not enabled high contrast in the Windows accessibility settings.

  • How can I remove a symbolic link to a folder in Windows 7 64 bit?

    Windows 7 Ultimate SP1 64 bit. Malware any created symbolic links in Windows Defender files. Specifically the en-US folder - it now points to C:\Windows\System32\config:

    14/07/2013-13:40

    .
    14/07/2013-13:40 ...
    12/04/2011 01:17 en - US.bad [c:\windows\system32\config]
    0 file (s) on 0 bytes
    3 dir 136,375,107,584 bytes free

    I Googled it and everybody says 'just use rmdir. THA does not work

    C:\Program Files\Windows Defender.bad > rmdir en - US.bad
    The directory is not empty.

    Is there another way to remove a link? I tried mklink to change the link in an empty folder - no joy:

    C:\Program Files\Windows Defender.bad > mklink /D EN - US.bad D:\TEMP\Empty
    Cannot create a file when that file already exists.

    Why MS did not provide a way to separate a folder? Seems pretty basic that there should be a way to cancel a link operation. Of course, I can't delete my config folder. I'm trying to avoid having to start over from scratch - help!

    I had the same problem and I solved it.

    Prompt orders open and administrator, and type

    CD "C:\Program Files\Windows Defender.bad"

    fsutil reparsepoint delete en - us

    fsutil reparsepoint delete backup

    fsutil reparsepoint delete drivers

    After that, to us, backup and driver records - return to their State of origin. You can delete the parent folder and start a clean install.

    Apparently, the malware transforms these symbolic links directory entries without changing their "file properties". This explains why rmdir does not remove them.

    fsutil restores the malicious acts and you can delete these directories.

    I'm not an expert on the file system, but this seems to be a bug in the management of NTFS symbolic links. Microsoft may take into account in this situation?

    I need 280 MB of storage on my iPhone. The capacity is full. How can I increase the capacity of the phone?

    You cannot increase the capacity. You must remove things. Go to settings > general > storage & use iCloud > storage > storage management and see what about space.

    I have an iPhone 6 and use Verizon as my server. How can I increase the number of rings until it go to voicemail?

    You can not. There is no adjustment to make on a phone. In fact, it is not based on the number of rings, it is a problem of synchronization based on the parameters of the call. You can contact Verizon to see if they can increase at that time here, but even if they can, it won't be much, only a few seconds if they do at all.

  • After updating Firefox, the font on my screen size has been reduced for all applications. How can I increase the size of the font on my screen?

    After the update, the next screen shows all the letters in smaller characters, with fewer pixels. All screens are like that now, and I found nothing in Firefox Help content. It is a problem because I have vision problems. So, how can I increase the font size that had it before? My screen is approximately 20 inches wide.

       Also, any chance I can change all the font to Arial instead of Times New Roman?

    Hi shbuzz2001,

    Have you tried to increase the amount of zoom by pressing on CTRL and + a few times? This article will show you how to use the Zoom.

    You can also check out the Knowledge Base article on the accessibility in Firefox - make Firefox and work of content for all users. It deals with default fonts and other options that may interest you.
