Intel Desktop Board D945GCZ Technical Product Specification
2.13 Reliability

Table 33 provides maximum case temperatures for the components that are sensitive to thermal
changes. The operating temperature, current load, or operating frequency could affect case
temperatures. Maximum case temperatures are important when considering proper airflow to cool
the board.
Table 33.
The Mean Time Between Failures (MTBF) prediction is calculated using component and
subassembly random failure rates. The calculation is based on the Bellcore Reliability Prediction
Procedure, TR-NWT-000332, Issue 4, September 1991. The MTBF prediction is used to estimate
repair rates and spare parts requirements.
The MTBF data is calculated from predicted data at 55 ºC. The MTBF for the D945GCZ board is
108,165 hours.
