Memory errors and memory hardware replacement constitutes a significant
portion of downtime and dissatisfiers for Sun customers. In addition,
roughly 80% of the DIMMs returned to our memory vendors are diagnosed
as "no trouble found" (NTF), indicating good components are being
replaced. Therefore, understanding the causes of memory errors and
proper diagnosis of the faults is key to maintaining optimum system
reliability and uptime.
A "Best Practices Guide for Memory Errors in UltraSPARC III Products"
has been produced as the result of a Sun Sigma project. This best
practices guide describes the different memory error events and then
steps the reader through the process of identifying the component that
triggered the event.

need arises.
