Server Crash... Bad Memory

Image
I've spent about three hours checking and sorting out the machine which went down, and come-what may I found problem after problem, but not with any of the software.  If your software checks out then there's an obvious other place to look... Your hardware. My first step was to remove the drives, specifically my ZFS devices.  No difference, everything still broke. I then set about systematically removing one piece of hardware at a time, first my quad ethernet card, no difference, then I removed the added dual SATA card still broke... Finally, I removed all the memory and inserted just one stick...

The motherboard hosting this is a very trusty Asus P6X58-e, I've loved every minute of this board, and hope that applying the overclock will be as easy as everything else working with it. As I am o...
