Presumably everyone is now no stranger to the Windows 7 system, but for its mystery and many new features is worth exploring, to be honest, as long as the current mainstream computer configuration I can "carefully" tell you that the Windows 7 system will never let you down. The serious personal opinion after I used it is "It will be used faster and faster! Especially web browsing!" >Note: With Windows 7 system, the memory is especially strict! Be careful when installing the machine, don't let JS flicker and buy it as a black film, then your nightmare will start, there will be a constant blue screen looking forward to you!
Okay Cut into the topic, below to post a crack tutorial using 4G memory, of course, you must first take a professional hardware detection tool to check how much memory your motherboard supports. If it is less than 4G, then don't be busy!

Although 64-bit operating system can support large-capacity memory very well, we have to mention 64-bit now. Software is not very much, but Vista and 64-bit versions of Win7 on compatibility or inadequate. On the other hand, 4GB of memory is no longer a stumbling block because of the current low memory price, so 4GB of memory has become the mainstream configuration. But what bothers users is that 32-bit Windows 7 and Vista do not allow 4 GB of memory.
In fact, the reason for less than 4GB of memory is in the 32-bit X86 architecture. The 32-bit X86 architecture means that the address bus of the personal computer is 32-bit. The CPU, memory controller, and operating system are all designed according to the 32-bit address bus. The memory address code that the 32-bit address bus can support is 4096MB. These 4GB address codes can be allocated to 4GB of memory. However, other registers require the system to assign their address codes, so a portion of the memory with a total capacity of 4 GB cannot be used without the address code.
Memory uses only 3.25GB
In fact, Vista/Win7 itself fully supports more than 4GB of memory, but Microsoft does not allow it. But in fact, on Win7 you can crack the Windows PAE kernel file ntkrnlpa.exe through the program, bypassing the license restrictions of the Zw Query License Value API function, and let 32-bit VISTA/Win7 support more than 4GB of physical memory. Below I will teach you how to crack 4GB memory. mystery of.
First of all, we need to download a software called Readyfor 4GB
Readyfor 4GB download address
Readyfor 4GB software
Download and decompress, run Readyfor 4GB first, when the program is opened, Click on the Check and Apply option and the program will tell you which system is capable of supporting the maximum memory capacity and current memory capacity. The picture below is shown after the author has cracked, allowing up to 4GB of memory.
Readyfor 4GB software
Then run the AddBootMenu program in the compressed package. When the dialog box pops up, enter Y and press Enter. At this point, the system prompts that the crack operation is successfully completed.
(PS: This step must be run as an administrator: enable and log in to the system administrator account.
In order to get the highest operational privileges, all the operations described in this article must be performed under the Administrator account, Win7 Administrator account The default is off, so you need to turn it on. Right-click on “Computer →Manage”, double-click “local users and groups →user”, right click on the account listed on the right“ Administrator→Properties", in the pop-up interface, cancel the checkbox of “Account is disabled" before logging out. Use “Administrator” to log in.)
The third step is to select my computer right click &rarr ;Attribute → advanced system settings → start and failure recovery & rarr; set → select the crack start 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 below.
Memory is recognized as 4GB
Let's take a look at the performance difference between the 4GB memory performance after cracking and the 4GB capacity memory under 64-bit Win7.

◎ SiSoftware Sandra2009 Test
This is a powerful system analysis and evaluation tool with more than 30 kinds of test items, including CPU, Drives, CD-ROM/DVD, Memory, SCSI, APM/ACPI, mouse, keyboard, network, motherboard, printer, etc. Full support for current VIA, ALI chipset and Pentium 4, AMD DDR platforms. In addition to its powerful features, it is easy to use and easy to use.

It is seen from the test that although 64-bit Windows7 can perfectly support 4GB of memory, the score and 32-bit Windows7 are not much. Changes, it can be seen that without the support of good 64-bit software, it is impossible to play the performance of the 64-bit operating system.
Full-text summary: Through the simple three steps, we can easily support the most commonly used 32-bit Win7 to 4GB of memory, which is really good news for users with more than 4GB of memory. And we also found that although 64-bit operating system Windows 7 can support more memory, but only 4GB of capacity does not lead 32-bit Win7, so users who want to support 4GB of memory through 64-bit Win7 do not have to Upgrade, after all, there are still some compatibility issues with 64bit compatibility, so sensible users can experience this method.
