Windows 2008 32 OS not Supporting 6 GB Ram
Hello,
I have installed windows 2008 32 bit on Dell r710 that has 6GB ram but my OS utilizes only 4GB ram out it. I am looking for the workaround so that my os can utilize the full 6gb RAM. Please find the snapshot for clear picture.

Do a clean install using the 64 bit version of Windows Server 2008 or upgrade to Windows Server 2008 Enterprise. Or waste the other 2 GB. There is no workaround.

Its is the client requirement, Client is specific about the OS edition i.e windows 2008 32 bit without hyper V, so i cannot go for other versions.
Using PAE we can make it right ??

Are you sure you need 6GB? You are only using just under 1GB currently.
I want to reinforce what everyone else has said. 32bit windows can only use at most 4GB of RAM
Operating system Maximum memory support with PAE
Windows 2000 Advanced Server
8 GB of physical RAM
Windows 2000 Datacenter Server
32 GB of physical RAM
Windows XP (all versions)
4 GB of physical RAM*
Windows Server 2003 (and SP1), Standard Edition
4 GB of physical RAM*
Windows Server 2003, Enterprise Edition
32 GB of physical RAM
Windows Server 2003, Datacenter Edition
64 GB of physical RAM
Windows Server 2003 SP1, Enterprise Edition

128 GB of physical RAM
* Total physical address space is limited to 4 GB on these versions of Windows.

Check the following documents as this will hopefully explain the differences with RAM limits between the different version of Windows

Also check the following document for reasons why certain 32 bit OS will only see a maximum of 4 Gb's of RAM

if the client is looking for a windows 2008 operating system without Hyper-V, they they ought to have bought the windows 2008 standard x64 without hyper-v, not the 32bit one.
waste of money and effort.
no one can get this working as it cannot be done. (unless someone gets a x64 windows 2008, hacks the version label to say 32 bit and hands over that dvd to you)

That's fine; you're using a 5500 or 5600 series CPU which has 3 memory channels, to achieve the best interleaving you should have all 3 channels populated which means 3 * 2GB sticks installed giving 6GB physical RAM. Installing Windows 32 on it gives 4GB usable but you're still benefiting on performance by having those three sticks rather than two.
Take a look at page 26 of http://h20195.www2.hp.com/v2/GetPDF.aspx/c01952610.pdf for example, makes no difference that it's a HP whitepaper rather than a Dell one since they're both using the same CPUs.

Oh, and PAE isn't going to be much use even though it lets you see 4GB rather than 3.75GB or whatever without it since that just relocates RAM from the PCI hole to above 4GB which their application probably can't use anyway.
