Intel Desktop Board DX58OG Technical Product Specification
2.7
Reliability
The Mean Time Between Failures (MTBF) prediction is calculated using component and
subassembly random failure rates. The calculation is based on the Telcordia SR-332,
Method I Case 1 50% electrical stress, 55 ºC ambient. 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 board is
82,351.2845 hours.
