sun t2000 ram configuration

I'm having a bit of trouble with my t2000 ... I suspect a bad stick of ram or the memory controller. Question is how do I go about determining the problem. I have 16 2Gb sticks installed but it doesn't show all of that physically connected... so any ideas?


I was able to boot up MartUX into a console... so I can run some diagnostics from solaris if that would help.

My ALOM battery is bad... so I'll probably replace that tomorrow so the system date will stay correct I don't know if that would affect anything else.

Code:
Current mode: NORMAL
Attaching network interface lo0... done.
Attaching network interface motfec0.... done.
