Well, I replaced DIMM0/1 (Infineon sticks with Infineon sticks).  On 
first boot, I was informed that the memory fault was cleared and the OS 
booted.  But 5 min later, the system rebooted with the same error as 
previously.

I am going to try booting this disc on my other SB2500 and see what happens.
