Windows Server 32 bit 2003 R2 not reconising 8gb only 4gb

Hi,

We have recently purchased 3 new poweredge 2950 servers with 8gb Ram and 32bit windows 2003 r2 server os for it. Unfortunately to my horror it is only reconising 4gb? Yet the the bios reads 8gb. I was under the understanding that 32 bit win2003 supported up to 32gb?. I have tried adding to the boot ini /PAE and /3GB but it hasnt gone up at all
Is there any thing else i can try?

Kind Regards,
LVL 4

That is all you can see have have. If you want all, use 64 bits.

Your BIOS is not dependent on memory address allocation limits like the operating system. It just reads the amount of ram installed.
As PUNKY has mentioned, the Windows Server 2003 R2 version is only a 32bit OS and cannot support more than 4GB in the OS.

You might be able to fudge a bit more with the /PAE switch added to the boot.ini file but this is indeed a limit with 32Bit OSs. In theory a 32bit OS can address 4Gb - but often its les than that as some address space is required for i/o etc.

Are you running 2003 R2 Standard or Enterprise?  Enterprise will support up to 32GB, Standard 4GB.  There is the limitations already mentioned with respect to how much can be mapped without using PAE.

See this (specifically Hardware specifications):
