    Highly unstable system (Supermicro X9DRi-LN4F)

    Thanks for the detailed replies guys! To eliminate some things: - I did refer to the manual and nothing is plugged into anything connected to socket 2, so I think I should be fine there. - All the RAM sticks are the same model and manufacturer, however I don't think they're the same batch...

    I've acquired a Supermicro SC847 system, and my current project is to quiet it down and reduce its power usage. The server came with 2 LSI HBA connected with 2 cables each to the front and rear backplanes. Does this look right? According to the manual the two ports are Primary SAS connector...
