Tru64 v5.1B
Dual CPU
2G memory
PROBLEM: cpu 0 panic system uncorrectable machine check
ON BOOT: error identifies problem in Bank 3 DIMM 0 Byte 4
NOTES:
* We have swapped to a different chassis/motherboard/etc using only same CPUs
and memory
* CPU0 swapped with spare
* CPU0's memory swapped with spare
* We then took the original CPU0 and put it into CPU1 (still cpu 0 panic)
* We reduced the memory down to 1M (so that above dimm/bank was empty)
* We have swapped the memory between the two banks (expecting to see the error
move, it did not).
We have replaced everything, tried moving CPUs and memory (cpu0<->cpu1) to see
if the problem traveled. We are still crashing and always on boot we see the
same memory error even when memory was swapped out and when no memory was in
that bank.
