This is a small command line tool that will patch the needed system files to enable 4GB and more of memory in Windows Vista SP2, Windows 7 RTM and SP1, and Windows 8 RTM 32-bit. Follow the steps below to enable a patched system, the core system files ARE NOT overwritten meaning you can revert back without too much fuss. By the way for the people who are still in love with 32 bit windows but have more than 3GB of RAM installed on their PC. They can use the PAE patch for windows 7. It is tested on Windows Vista SP2, Windows 7 SP0 and Windows 7 SP1. Note: Download That periodically updates software info, pricing of PAE patch from the developer. A 32-bit OS can theoretically use up to 4 GB of RAM, but 32-bit versions of Windows Vista and Windows 7 see a maximum of 3.12 GB. With 64-bit Windows 7, you can use the full 4GB RAM. You get better security with 64-bit Windows. All 64-bit device drivers are digitally signed, which means you will not have random crashes. PAE patch 1.0 Download: A lot of people still prefer to use 32 bit version of windows 7, but 32 bit version of windows doesnOCOt allow you to use more than 3GB ( 4GB theoretically, 3GB practically ) of your RAM. In fact there is a workaround for this problem on 32 bit OSes, it is know as PAE ( Physical Address Extension ) which already exists on Windows too but Microsoft has.

Mar 12, 2015 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 hardwa.

Physical Address Extension (PAE) is a processor feature that enables x86 processors to access more than 4 GB of physical memory on capable versions of Windows. Certain 32-bit versions of Windows Server running on x86-based systems can use PAE to access up to 64 GB or 128 GB of physical memory, depending on the physical address size of the processor. For details, see Memory Limits for Windows Releases.

The Intel Itanium and x64 processor architectures can access more than 4 GB of physical memory natively and therefore do not provide the equivalent of PAE. PAE is used only by 32-bit versions of Windows running on x86-based systems.

With PAE, the operating system moves from two-level linear address translation to three-level address translation. Instead of a linear address being split into three separate fields for indexing into memory tables, it is split into four separate fields: a 2-bit bitfield, two 9-bit bitfields, and a 12-bit bitfield that corresponds to the page size implemented by Intel architecture (4 KB). The size of page table entries (PTEs) and page directory entries (PDEs) in PAE mode is increased from 32 to 64 bits. The additional bits allow an operating system PTE or PDE to reference physical memory above 4 GB.

In 32-bit Windows running on x64-based systems, PAE also enables several advanced system and processor features, including hardware-enabled Data Execution Prevention (DEP), non-uniform memory access (NUMA), and the ability to add memory to a system while it is running (hot-add memory).

PAE does not change the amount of virtual address space available to a process. Each process running in 32-bit Windows is still limited to a 4 GB virtual address space.

System Support for PAE

PAE is supported only on the following 32-bit versions of Windows running on x86-based systems:

  • Windows 7 (32 bit only)
  • Windows Server 2008 (32-bit only)
  • Windows Vista (32-bit only)
  • Windows Server 2003 (32-bit only)
  • Windows XP (32-bit only)

Enabling PAE

Windows automatically enables PAE if DEP is enabled on a computer that supports hardware-enabled DEP, or if the computer is configured for hot-add memory devices in memory ranges beyond 4 GB. If the computer does not support hardware-enabled DEP or is not configured for hot-add memory devices in memory ranges beyond 4 GB, PAE must be explicitly enabled.

To explicitly enable PAE, use the following BCDEdit /set command to set the pae boot entry option:

bcdedit /set [{ID}] pae ForceEnable

IF DEP is enabled, PAE cannot be disabled. Use the following BCDEdit /set commands to disable both DEP and PAE:

bcdedit /set [{ID}] nx AlwaysOff
bcdedit /set [{ID}] pae ForceDisable

Windows Server 2003 and Windows XP: To enable PAE, use the /PAE switch in the boot.ini file. To disable PAE, use the /NOPAE switch. To disable DEP, use the /EXECUTE switch.

Comparing PAE and other Large Memory Support

PAE, 4-gigabyte tuning (4GT), and Address Windowing Extensions (AWE) serve different purposes and can be used independently of each other:

Maximum Ram 32 Bit Windows

  • PAE allows the operating system to access and use more than 4 GB of physical memory.
  • 4GT increases the portion of the virtual address space that is available to a process from 2 GB to up to 3 GB.
  • AWE is a set of APIs that allows a process to allocate nonpaged physical memory and then dynamically map portions of this memory into the virtual address space of the process.

When neither 4GT nor AWE are being used, the amount of physical memory that a single 32-bit process can use is limited by the size of its address space (2 GB). In this case, a PAE-enabled system can still make use of more than 4 GB of RAM to run multiple processes at the same time or to cache file data in memory.

32 Bit Ram Limit

4GT can be used with or without PAE. However, some versions of Windows limit the maximum amount of physical memory that can be supported when 4GT is used. On such systems, booting with 4GT enabled causes the operating system to ignore any memory in excess of the limit.

AWE does not require PAE or 4GT but is often used together with PAE to allocate more than 4 GB of physical memory from a single 32-bit process.

In this tutorial , I’ll be guiding you on how to enable 4GB of RAM on Windows 7 32-bit. This is handy especially if you are planning to use your old Windows 32-bit without the hassle of going through reformatting and re installing Windows 7 64-bit as there is no way to upgrade from 32-bit OS to 64-bit OS. Before we start , be sure to backup your system and you also would also need to download the patch here . If you prefer to do it for yourself , scroll down and read
DISCLAIMER : Bear in mind that we are going to change our system here. For instance you may enter Twlight Realm and you may be a fan of Justin Bieber afterwards. I am not held responsible if such incident occurs. So be sure to backup your system before attempting to do so.
Simply run the patch and select patch 4GB of RAM and reboot ! If you did correctly , voila you should see something like this. Congratulations , now your 32-bit Windows 7 supports > 4GB of RAM !

Why bother tweaking Windows 7 32-bit ?
As you may have guessed. There is a 64-bit version of Windows 7 which supports more than 4GB of RAM. But suppose if you are still using 32-bit of Windows and have upgraded your RAM and still insist of keeping your Windows (as you have tons of collections of stuff installed). This is where the patch comes handy. It just allows 32-bit Windows 7 to see more than 4GB of RAM.
So how does this magically tweak work ?
It is simply. This tweak pretty much hacks the kernel to support Physical Address Extension or PAE . Basically all processors do have PAE , what PAE does is that it allows 32-bit OSes to see more than 4GB of RAM. It acts as a translator , trying to break the limit of 32-bit. Yes there is a limit , but with the help of CPU , the limit can be broken and the Operating System can someone see this RAM. Instead of accessing directly , it uses PAE to acts a translator to address memory location beyond the 4GB realm. Remember that 32-bit processor can only address 4GB of memory space , this extends it to 36-bit (or sometimes up to 40-bit). So with the help of CPU and if the OS (Operating System) supports PAE , you could address this issue. For some reason Microsoft did not enable it for Home Operating Systems such as Windows. However PAE is enabled in many other Operating Systems such as MacOSX 10.5 and above and Linux (provided the 32-bit kernel is compiled with PAE)
What are the drawbacks ?
There is one – you are still limited by the law of physics and computing. Well , you can’t play God here !. Since our system is 32-bit , therefore the instructions are still in 32-bit and we are still bounded by 32-bit instructions .Suppose if you have 6GB of RAM and you have PAE turned on and you want to use Lightroom for instance – even at most Lightroom can only use up to 4GB. It can’t use anything beyond that. This is because that the instructions are in 32-bit still. So in other words applications can only ‘see and use’ up to 4GB. Anything beyond that , they can’t use at all.
If that’s the case , what are the advantages ?
Firstly you would have more memory which means that you could run more applications on your 32-bit system. Without PAE enabled (suppose if you have 8GB of RAM installed , Windows would only see and address up to 4GB). Imagine if you want to run photoshop and lightroom concurrently , it would not be possible. However with PAE turned on you could run these programs in main memory. Even though the application can only use maximum up to 4GB of RAM. You could now able to load these applications in RAM directly which should increase your productivity (since program takes less time to load if they are located in memory compared to hard disk)
I like to get my hands dirty. So how do I do it myself ?
Kindly read the guide here. In fact that site helped me to write this guide that explains the concept in plain English
