Server 32bit 2008 Enterprise

Hello Experts,

please look at the attachment and help out, it is the server 2008 enterprise 32 bit, normally 32 bit operating system can take up to 4 GB RAM even if the hardware has 32 Bit GB RAM, but here it hows 32 GB RAM and seems it is using the entire RAM which is allocated. Can anyone please explain me is this possible ? I need more understanding on this ?

Regards, Shiva

Enterprise Edition could use more than 4GB of RAM. Only Standard Edition was limited to 4GB.

This is supported by PAE (Physical Address Extension) which changes the way the memory addresses are translated.  Remember that despite the fact the OS can address the additional memory using this technique, it is still 32 bit, and therefore any single process still cannot use more than 4gb.

Windows automatically enables PAE if DEP is enabled on a computer that supports hardware-enabled DEP, or if the computer is configured for hot-add memory devices in memory ranges beyond 4 GB. If the computer does not support hardware-enabled DEP or is not configured for hot-add memory devices in memory ranges beyond 4 GB, PAE must be explicitly enabled.

Thanks for all your help experts.
It should be noted that the barrier introduced in Microsoft OS' with 32 bit is purely artificial. It ensured, that the enterprise/datacenter editions, which costs most, get sold. Please google for the term "licensed memory" if you don't believe it. http://www.geoffchappell.com/notes/windows/license/memory.htm is where you get when you click on http://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&cad=rja&ved=0CCUQFjAA&url=http%3A%2F%2Fwww.geoffchappell.com%2Fnotes%2Fwindows%2Flicense%2Fmemory.htm&ei=2CjxUqjsA8HNtQaUy4CAAQ&usg=AFQjCNEzHj0L_m2GE5pLTQimuEzu7xLdsQ&bvm=bv.60444564,d.Yms (direct links forbidden)

[Yes, of course the memory-per-process-limit is not windows-only but seen on other 32-bit-OS' as well]
