32-bit WINDOWS7 system using 4G memory cracking tutorial

I think you are now on the Windows 7 system is not unfamiliar with it, but for its mystery and many new features still worth discovering, to tell the truth, as long as the current computer mainstream configuration, I can "prudent" to tell you, Windows 7 system will never let you down, After I used the serious personal opinion is "it will be used more quickly!" especially web browsing! "

Note: With Windows 7 systems, the memory is particularly stringent! When installed carefully ah, do not let JS fooled to buy black film, so your nightmare began, there will be a continuous blue screen look forward to you!

OK, cut to the point, the following paste a use of 4G memory of the crack tutorial, of course, you have to take a professional hardware testing tools to check your motherboard maximum support of how much memory, if less than 4G, then do not busy!

Although the 64-bit operating system now supports large-capacity memory, we have to mention that 64-bit software is not very much now, and that the 64-bit version of Vista and Win7 is not compatible. On the other side, because of the lower memory price, 4GB capacity memory price is not a stumbling block, so 4GB capacity memory has become the mainstream configuration. But what bothers the user is that 32-bit Windows7 and Vista do not allow 4GB of memory.

In fact, less than 4GB of memory is the reason for the 32-bit X86 architecture. 32-bit X86 architecture refers to the personal computer's address bus is 32-bit, CPU, memory controller, operating system is based on 32-bit address bus design. The 32-bit address bus can support the memory address code is 4096MB. This 4GB address code can be allocated to 4GB memory. But other registers require the system to assign them to the address code, so a portion of the memory with a total capacity of 4GB is not allocated to the address code and cannot be used.

Memory only uses 3.25GB

In fact, vista/win7 itself fully supports more than 4GB of memory, but Microsoft is not allowed to use it. But in fact on the Win7 can through the program to crack Windows PAE kernel file Ntkrnlpa.exe, bypassing ZW Query License Value API function license restrictions, so that 32-bit vista/win7 support more than 4GB of physical memory, I'll teach you how to crack 4GB memory puzzle.

First, we need to download a software called Readyfor 4GB.

Readyfor 4GB Software

After the decompression, the first run Readyfor 4GB, when the program opened, click on the check and the application options, this time the program will tell you the system can support the maximum memory capacity and current memory capacity. The picture is the author has cracked after the shown, maximum allowable 4GB memory.

Readyfor 4GB Software

Then run the package inside the Addbootmenu program, when the pop-up dialog box, enter Y-return, at this point the system prompts the crack operation completed successfully.

(PS: This step must be run as an administrator: Enable and log on to the system administrator account.)

In order to obtain the highest operational privileges, all of the operations described in this article must be performed under the Administrator account, and the WIN7 administrator account is closed by default and needs to be opened. Right-click computer → admin, double-click Local Users and Groups → users, right-click the Administrator→ property in the account listed on the right, and uncheck the "Account Disabled" button in the pop-up interface.　Log on by using Administrator after logging off. )

The third step is to select My Computer right key → properties → advanced system settings → startup and failure recovery → settings → Select the cracked boot system can be, as shown below.

Select the Cracked program

Finally restart the computer, after selecting My Computer properties, the memory is recognized as 4GB capacity, as shown in the following figure.

Memory is recognized as 4GB

Let's take a look at the performance difference between 4GB capacity memory and 64-bit Win7 under 4GB capacity memory.

SiSoftware Sandra2009 Test

This is a powerful system analysis and evaluation tool, with more than 30 kinds of testing projects, including CPU, drives, Cd-rom/dvd, Memory, SCSI, APM/ACPI, mouse, keyboard, network, motherboard, printer and so on. Full support for current various VIA, ALI chipset and Pentium 4, AMD DDR platforms. In addition to having a powerful function, the use is also very convenient, easy to start.

64-bit 4GB Win7 bandwidth test

From the test, although 64-bit Windows7 can perfectly support 4GB capacity memory, but the results and 32-bit Windows7 has not changed much, there is no good 64-bit software support, can not play a 64-bit operating system performance.

Full-text summary: Through a simple three steps can make our most commonly used 32-bit Win7 can easily support to 4GB memory, for more than 4GB of memory users is indeed good news. And we also found that although the 64-bit operating system Windows 7 can support a larger capacity of memory, but only 4GB capacity does not lead the cracked 32-bit Win7, so you want to pass 64-bit Win7 support 4GB capacity memory for the moment do not need to upgrade, After all, there are some compatibility issues with 64bit compatible now, so perceptual users can experience this approach.
