Ram: Kingston HyperX blu DDR3-1600 DC - 16GB (2x8G none ecc)
PSU: 300W Gold (included with Fractal-Design-Array-R2-Mini-ITX)
Kingston SSDNow V300 SSD - 60GB (on intel controller)
Western Digital WD Red - 4TB (on marvell controller)

Bruger følgende software
Os: Debian testing (stable har ikke netkort driver)

Den køre stabilt så lægen den er idle

eneste jeg kan gøre er ctrl + alt + del fra consol for at genstarte

den giver også nogle af disse i dens indbygget IPMI
System Reconfigured,OEM System Boot Event,Undetermined System Hardware Failure,Entry Added to Auxiliary Log,PEF Action - Asserted


Jeg har efterhånden prøvet en hel del.
8 timers ram test (ingen fejl)
2 timers cpuburn test. (den bliver lidt varm 60 grader men crasher ikke)
Updateret nic driver (igb til nyeste)
flyttet data disk fra marvell controller til intel
disabled AES-NI
disabled intel speed step

opdateret kerne til mange forskellige version pt 3.14 rc7
før fik jeg mange random fejl (panic, cpu not syncronized, double fault etc.)
nu får jeg kun overstående


håber nogen kan pege mig i den rigtige retning.
