Windows 7 operative system and your PC’s hardware are limiting the maximal amount of memory that your PC can use. For 64-bit operating systems, that limit is theoretically non-existent, as 64-bit systems can read and use 192 GB of available RAM. For 32-bit operating systems, the set limit is 4GB of RAM. This means that the operational RAM will be anywhere between 2.75 and 3.5 GB because, depending on your chipset and motherboard, Windows kernel will block a good part of your RAM into ‘hardware reserved’.
However, I was also told that Windows 7 32 bit limits the usage of RAM for each application at 2 GB. Does this patch remove also this limit? Does this patch remove also this limit? In case it doesn't, do you know a way to get rid of this limit and to use at least 4GB for application, which I think it's the maximum possible for a 32 OS (as 2^32. Now use 4gb RAM fully in Windows 7 (32 bit) Ram,Windows 7,Tips & tricks,Full ram use in windows. But with a little PATCH FILE we can use the 4gb RAM fully. Then open the patch file again. Craneware online toolkit. And click on Remove Watermark. Then restart your computer. Couple of months back, I had blogged about a peculiar Windows 7 issue which could cause a BSOD (Blue Screen of Death) if the system had 4GB (or more) RAM. I managed to find a fix for that issue. Filed under: Windows — Tags: 32 bit, 4GB, 7, limit, ram, seven, Windows, x86 — admin @ 2:19 pm A lot of people still prefer to use 32 bit version of windows 7, but 32 bit version of windows doesn’t allow you to use more than 3GB ( 4GB theoretically, 3GB practically ) of your RAM.
This limitation is a consequence of IO memory mapped reservations that are overlaying the physical address spaces and are masking them out so the working memory cannot utilize them. This behavior is not dependant on the OS the machine is running.
Very large portions of address spaces below 4GB, which is also the highest accessible address for 32-bit systems, are being reserved for system hardware, such as PCI bus, bridges, BIOS, legacy video support, ACPI, etc. At least 256MB to 768MB will be reserved by PCI Express support only, depending on installed memory on your graphics card.
The direct consequence of these hardware reservations is that an average system is cut short for anywhere between 265 MB and 1GB, which are then inaccessible for your OS.
Intel chipsets are especially known for reserving certain address ranges by default and they often have fixed 1.5GB that is always reserved and unusable by Windows.
Although many claim that it is impossible removing this memory limit, it has proven to be wrong, as it is very much possible. A group of Russian programmers have provided a hacked kernel, which you can use to fix this limitation.

According to Microsoft themselves, this is a well known problem and they have even released a special Windows Server 2003 Datacenter edition , that supports even 64GB of RAM. It has also been known that all Windows Vista 32bit editions contain the code that would allow usage of physical memory even beyond 4GB, but Microsoft didn’t unlock that code.

Some Antivirus programs may detect this program as a trojan, which is certainly false. You can simply temporarily disable it, or add the file to your antivirus’ exceptions list. It will be enough to allow undisrupted download and installation of the file.
Still using a 32-bit Windows machine? Here’s how to remove the 4GB limit that might be hampering your RAM usage.
While 32-bit was once the standard, in recent years more and more Windows users have migrated to the 64-bit version of the OS. However, there are still some holdouts using 32-bit systems — and they might well be missing out on some of the potential of their hardware if they haven’t addressed a known issue with RAM on that sort of machine.

Why Am I Limited to 4GB of RAM?
The reason behind the so-called ‘3GB barrier’ lies in the architecture of 32-bit operating systems. Each individual byte of RAM has its own physical address that the system uses to access particular units of memory. 32-bit systems have a limit on the amount of addresses available for RAM and various other components. Depending on your setup, this can limit the amount of RAM your system can support to somewhere around 3GB — although it could be slightly higher or slightly lower.
A technique called physical address extension, or PAE, can allow a 32-bit OS to support up to 64GB of RAM. By increasing the physical address size from 32 bits to 36, there are plenty more addresses available for the system to use — but the system’s virtual addresses stay the same, ensuring that everything works just as it should.
How Can I Tell If I Need PAE?
Whether or not you need to utilize PAE will come down to two important factors; are you running a 32-bit or 64-bit version of Windows, and how much of your installed RAM is usable? To establish both, open up Control Panel, and navigate to System and Security > System.
If you see something similar to the above, then you’re already sorted. However, if the System type reads 32-bit Operating System and there’s a bracketed entry stipulating how much of your RAM is usable, following the result given for Installed memory, you’ll need to make use of PAE in order to get the full effect of your RAMHow To Upgrade A Laptop's RAM, Step By StepHow To Upgrade A Laptop's RAM, Step By StepIs your laptop old, slow, and has the hardware never been upgraded?

First things first, download PatchPae2 from wj32. This will give you a .zip file containing a patch that will work for machines running either Windows 7 or Windows 8/8.1, but there’s a few slight differences between the processes for versions of the OS pre- and post- Windows 8. Start by unzipping the file you downloaded and placing it in a folder inside Windows > System32, which will likely be found on your computer’s C: drive. Once PatchPae2.exe is in place, make a note of its file path, as you’ll need this later on.
Now, open a Command Prompt with Administrator privileges enabled. You can do this easily by searching your system for Command Prompt, and then right-clicking the correct entry in the search results and choosing to Run as Administrator. You should be presented with the standard command line interface — ensure that the directory reads system32.

Next, patch the loader to disable digital signature verification by entering the command PatchPae2.exe -type loader -o winloadp.exe winload.exe. Then, create a new boot option with the following input: bcdedit /copy {current} /d “Windows (PAE Patched)”. The phrase between the quotation marks is simply a comment for you to label what you’ve done.

You should see a message that tells you that the copy was successful, and gives you a unique boot ID in the format {xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx}. Copy that ID, because we’re going to use it for the next few commands. Enter bcdedit /set {boot ID} kernel ntoskrnx.exe if you’re using Windows 8 or 8.1, and bcdedit /set {boot ID} kernel ntkrnlpx.exe for anything earlier.
There are just a few more commands that we need to run. First, make sure our patched loader is selected by inputting bcdedit /set {boot ID} path Windowssystem32winloadp.exe. Then, use bcdedit /set {boot ID} nointegritychecks 1 to confirm that the loader shouldn’t be verified. Then, set this boot entry as the default with bcdedit /set {bootmgr} default {boot ID}. You can also use bcdedit /set {bootmgr} timeout X to set a custom boot menu display time by replacing X with your desired length of time in seconds, but this is optional. All that’s left from this point is to restart your computer.
