Hi Gurus,
Thanks to Gyula Szemenyei, Werner Hahling, Paul Mercure, Grant Ward
and Chris Jankowski for their kind attention. Paul reports they
have faced the same problem in the same type of machine and solved
the difficulty by buying used memories - the new ones always caused
the machine to panic during boot or later in the day. Werner
suggests slower simms should come first when different brands are
mixed. Chris points out that dust and grime in the long unused
slots could also be a factor.
We solved our problem by cleaning and blowing the empty slots carefully
and by combining only the two pairs of 32Mb from Digital. The
new pair of simms had to come first (aren't they the faster ones?)
The pair from Dataram (and not from Kingston as stated in my original
message) simply is not accepted alone or mixed with the other ones.
Cheers,
