OT: Spolehlivost PC HW - pro zajimavost

[Ales Prochaska]

A ono i to "mezi dvema poruchami" je zavadejici. Takovy mainborad se
poroucha jen jednou :-)

>> The MTBF data is calculated from predicted data at 55 şC. The MTBF calculations for the boards

>> • D845BG board MTBF: 140818.2951 hours
>> • D845PT board MTBF: 143991.3836 hours
