Win7 system 4G memory Why only 2G memory available

I use 32-bit Windows 7 operating system, according to the theory can recognize 3.25G memory, of course, if you are using integrated graphics, this value may be even lower. At present, some netizens have responded by installing "memory (RAM): 4.00GB (2.00 GB available)" in "Checking Basic Information About Computers" on your computer. As shown below:

We can see that the system has recognized 4GB of memory, then the initial judgment of the hardware is no problem, the problem is on the system (this part of the memory may be automatically set to hardware reservation by the system) Memory is up).

Workaround:

1. Open "Start Menu" - "Run" - enter "msconfig" point "OK" to open "System Configuration" 2. Find the "Boot" tab, As shown below:

3. Click on the "Advanced Options" card (remove the maximum memory before the hook), and then confirm. As shown below

Restart, can you solve it? Of course, if still still not restored to 3.25G (not integrated graphics). Then directly select the hook, set to 3.25G, which is 3328M. If you want to support 4G memory perfectly, please use 64-bit operating system (theory supports 3.8G memory).
