[rescue] memory error on Ultra 1 - what should I do?

[Michael Horton]

it means the slots are bad.

the systemboard should be replaced.
or, at least, don't use the banks that the bad slots are part of.

I've been experiencing similar ECC errors on a recently acquired Ultra
2.
I've gone through several iterations of removing, cleaning, and
reseating
the memory, and swapping individual modules to different slots, but the
ECC errors stay with the same 2 slots, in my case U0401 and U0601. Any
idea what this means?

Anyway, I'm glad this machine works at all - when I got it, it was
*totally* dead  to the world, but it turned out to have a loose
connection
inside the power supply :)
