Hyper V: virtual machine will not accept memory more than 4 GB

I have Dell Power edge server 2950 with quad Core Processor and 32 GB RAM,
Win 2008 64bit Server and Latest Hyper V Final Release.
The virtual machine is running Windows 2003 SP2 Std Edition. I have assigned
8192 MB (8GB) RAM to this machine but this machine can only read 4GB.
What am I doing wrong?.
How can I make my virtual machine use all RAM assigned?

Thank you,
Mavi

Hi Mavi,

If this is Windows Server 2003 Standard, 32 bit, then it can only use 4GB.
To use more, you'd have to be running the 64 bit version.

Re: Hyper V: virtual machine will not accept memory more than 4 GB

The limitation is entirely in the operating system being installed. 32-bit
Windows Server Standard is limited to 4 GB. Period. 32-bit or 64-bit
Enterprise can use more, or 64-bit Standard can use more. But 32-bit
Standard is limited to 4 GB.
