Table 37 provides maximum case temperatures for the Desktop Board D915GEV/D915GRF
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 Desktop Board D915GEV/D915GRF.

Reliability
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 ÂșC.
The MTBF for the D915GEV and
D915GRF boards is 110,262 hours.
