To solve 32-bit Windows 7 lies that can use 4G of memory

These days in many web forums to see many people say that 32-bit Windows 7 can identify 4G of memory, some people say that the photo is PS, some people say that 4G memory is not the fault of Microsoft, I think it is very interesting, but my gut tells me it is impossible.

So, immediately installed a 4G 32-bit Windows 7 to play, and indeed in the system properties can be displayed in the 4G of memory.

But having read a piece of Mark's masterpiece translated by a Basin boss, convinced by the theory, is it that the theories of Windows 7 have been overthrown?

Run Msinfo32.exe immediately, sure enough, it is also 3.25G.

Then use Meminfo to look at the distribution of physical address, the display is also 3.25G

Sure enough, there seems to be only one truth, then go to the Device Manager and look inside.

CFF70000 to ffffffff this memory is a so-called "memory hole" and is occupied by the device

So, the 32-bit Windows 7 inside the so-called 4G memory is only reflected in the ability to recognize 4G, but only 3.25G.
