Perhaps the memory tests from the POST infrastructure. But from my experience 
a realworld application running under Linux is a good test. For example 
compiling a Linux kernel in a loop. Perhaps mounted via NFS. Something like 
this should fail at some time when SDRAM related problems exist.

That's good. Which OS was used here? Linux?

But Jerry's note about x-raying the problematic board is a good idea.
