I was already disappointed in the motherboard.  :-(

Overnight runs of memtest have not found a fault with either mem stick.  
Problems have occurred with each stick being the sole stick, and with 
two different processors, both were X2 3600+ AMDs.  I doubt that both 
cpus have the same problem.  sys_basher did not find any faults.  
Do you recommend anything in particular - like cpuburn?

I think that it is a motherboard problem, but I will let it run with 
nosmp for a while and see what happens.
