Weird problem in upgrade to AS600A 5/500

Hi all,

I was wondering if anyone else had seen this little oddity:

In an upgrade of an AS 600 4/x (x=266 or thereabouts)
to an AS 600A 5/500, we had a simm slot fail.
We swapped in a few different motherboards of the
same rev level (C1) and it made no difference. Ditto
for the cpu. Tried putting the graphics card in
a different slot, just for kicks, but of course that
didn't make any difference either.

During the initial test of memory, it gave errors along
these lines:

Bank 1, slot 2,

(address something or other) wrote aaaaaaaaaaaaaaaa read aaaa5555aaaaaaaaaaaa

and this repeated for something like 8 sequential addresses.

We took the memory out of bank 1 and are doing without it
for now.

Has anyone else done this upgrade, with or without problems?
