Win8.1PE SE 32bit only 2GB usable ( 8GB on board)

Hi
I just create 32bit version of Win8.1PE SE.
Unfortunatelly I noticed that only 2GB is usable by system instead of 3GB.
Is it correct?
I know that only 64bit system can use whole 8GB RAM.
Why 32bit version of Win8.1PE SE use only 2GB RAM?

Some memory is taken by loading the wim file into memory before windows loads, and this memory is not accessible by the environment.

Also, depending how you are loading it, you could be loading the ISO file into memory via grub4dos, *then* loading the wim file from that into memory as well (basically taking up double the memory).

Easy way to tell is if you make a smaller wim (take out something big like .net), do you have more memory available?

The RAM you have is reduce by the size of the WIM file and the size of the two ram disks.
Maybe even a graphic card uses same.

One could easily unlock the full 8 GB, but the right solution is to use an x64 winpe 

Hi
Whatever I do I still can see only 2GB :(
It is depend on option OS in RAM or PE in RAM or something that.
Is it correct?
In WIN8PE SE I can see 4GB.
