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.
