[Bioclusters] problems with AMD Athlon 2000+ MP

[bioclusters@bioinformatics.org]

Hello,

We have a 20 CPU cluster which has AMD Athlon 2000+ MP processors.  The
cluster is relatively new and almost every week we loose one or two nodes
due to the processors failing.  I think the issue may be heat related, so
we tried separating the nodes, increasing the airflow with a fan, and
dropping the temp in the server room.  None of these attempts have helped.
We have also tried to replace the fans.  Has anyone ever had a similar
problem?  How did you resolve it?  Are pentium III more stable?

Thank you in advance!
Bonnie
