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 ºC. The MTBF for the Intel
Desktop Board D945GCLF2 is 75,716.67728 hours and for the Intel Desktop Board
D945GCLF2D the MTBF is 76,277.65065 hours.
