Technical Reference For information about Processor datasheets and specification updates Intel Q43 Express chipset datasheets, specification updates, and design guides Refer to Section 1.2, page 14 http://www.intel.com/products/chip sets/index.htm 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 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 Intel Desktop Board DQ43AP MTBF is 137,185 hours. 2.8 Environmental Table 28 lists the environmental specifications for the board. Table 28.
