hardware problem?

Can someone tell me what the following means? We have a v440 running Solaris 9. What do the patterns actually mean?

looks like a dimm ist faulty... do a cross change an check if the fault is another than before...

I agree with Duke, Run Post diagnostics or VTS to verify.

We reseated the memory so the DIMMs are OK. We still get this:

What is a UE and is there anything we have to do?

UE =uncorrectable error. I wish reseating memory was all that was needed to repair failed memory. Did you run diagnostics?

We reseated all the modules for that CPU. cediag was run.
