Unless you spend days at it you cannot do a good memory check/test.
I don't want to wait days while my system boots. A cursory check
That verifies the memory doesn't totally suck is ok. But I don't
want to see anything that conveys the impression that LinuxBIOS
has actually checked the memory.
The best tests I know of involve monitoring for ECC errors while
the system is being stressed.

I'm not certain you can plug that many 4G dimms into an Opteron. At the
very least they are a challenge to come by...
As for setting up and debugging memory the first system with LinuxBIOS
on the Opteron Lighting had 6TB of ram...
