Xeons have 36 address lines, so it can have up to 64Gb of RAM. You will not have
*linear* address space, but you still can use all that memory.

On Windows your process can use system calls to map different areas of physical
memory into your address space. SQL Server uses that API, and it can utilize all
that RAM.

Other alternative is to let OS handle that memory. It will be used for file
cache, or you can run several memory-hungry applications simultaneously.

Thanks,
Eugene
