Hi, we have a pair of Ultra 60's which started out with 2GB RAM each
(16 128MB DIMMs). Over the past 5 years we've periodically gotten
memory errors forcing us to remove banks, and are now down to 1GB on
one box and 500MB on the other :-(. The boxes are under heavy, fairly
critical use, so I don't want to spend a lot of time trying to
conclusively pin down which DIMMs are bad - if any! (IE it could be
corrosion on the motherboard or something.)

Does anyone know of a place where I can send the 20 DIMMs we've had to
pull, to do some conclusive testing?

Thanks,
Ralph

Does POST not catch the errors?

For this it is best to set diag-level to max.

Docs on how to do this are at:
http://docs.sun.com/source/805-1709-...2-7.html#20710

If that doesn't catch them then you could try flashing your PROM and
running a max post again. Patch 106455-11 is the latest (last?) PROM
update for the Ultra 60.

Where can I have Sun memory TESTED?
