Please don't mark posts as urgent. This isn't urgent for anyone but you.

How do you know your system is only using 4 out of 8 GB?? What tests have you done? Do you see the RAM show up in the POST/BIOS screens?

Chances are you're not running the bigsmp kernel, which supports memory >4gb. Since you have SuSE Enterprise server, you've paid for support through Novell, I'd suggest contacting them. They will either have a new kernel or a kernel patch available to correct this issue.

As you haven't yet chosen to answer that question, I assume that your definition of urgent is slightly different from the normal one. As you will know, "urgent" is a well known way of irritating people, you have probably reduced the chances of getting an answer for no apparent reason.

Normally, in my experience, SuSE is pretty good at installing an appropriate kernel, so why this should happen is a bit of a mystery. Have you upgraded the memory after installing, perhaps? SLES 9 is a bit old though, and maybe when it was released the availability and automagic install of appropriate kernels wasn't as good.
