windows 2003 enterprise don't use more then 4GB RAM with LH 6000

[dario binetti]

I had installed windows 2003 server entreprise on my lh6000 6 xeon 700MHz and 6GB RAM. Windows works correctly but, even if the information service sees all the memory, server use only 4GB (or something less).
I need to expand memory to 8GB, but I'm not sure that windows uses all the memory. Help

Dario,

If your installing Enterprise, the OS will support up to 32GB so you won't have a problem there! It's more than likely a hardware limitation, certainly not the OS

According to microsoft, W2K3 Enterprise edition can use up to 32GB of ram:

The CPU can only address 4GB native, however.
