Win7 can not use 4G memory solution

Let's first take a look at how to make 32-bit win7 use 4G memory. First of all, we need to download a software called Readyfor 4GB, users can search on the search tool, there are many download addresses.

After downloading and unpacking, run Readyfor 4GB first. When the program is opened, click Check and Apply. Then the program will tell you that the system can support the maximum memory capacity and current memory capacity. 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. Note that this step must be run as an administrator

The third step is to select my computer right click → attribute → advanced system settings → start and failure recovery & rarr; set → select the crack start system Yes, 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

But there is a reminder here: this will cause the system to be unstable, which may cause the system to have a blue screen for no reason, or an abnormal startup. Because Readyfor 4GB is a software that cracks the Windows PAE kernel file ntkrnlpa.exe, bypassing the license restrictions of the ZwQueryLicenseValue API function, enabling 32-bit x86 Vista/Windows 7 to support more than 4GB of physical memory. Whether this is appropriate or not remains to be verified, and the description of the blue screen phenomenon in the software description is:

Some old drivers do not support more than 4GB of memory addressing, resulting in malfunction, even blue screen Crash.

Please set the system error report to generate the memory dump file *.dmp, analyze dmp, find out which driver has a problem, update it, or disable it.

Some of the additional features of the motherboard will not support 4GB and cause a blue screen.

Blue screen is not directly related to Windows and patches. Windows Vista/7 itself fully supports over 4GB of RAM.

The same hardware will have the same problem in 2003 or 2008.

From this point of view, these problems should be related to the driver or some motherboards. Again, here to remind the netizens, if you use this method to make 32-bit win7 use 4G memory, it is likely to cause various problems in the system, please use it carefully!
