All twelve systems are water cooled, and run anywhere from 20-35% overclock 24/7. ALL systems have loadline calibration enabled and there have been zero cpu failures in any of these systems.
Discussions in another forum aluded to the fact that certain individuals here at XS have experienced failure or fried 45nm chips and feel LLC is to blame.
If you're one of those to be so unfortunate, I would appreciate a short reply with your thoughts and observatons.

This is not mysterious at all. LLC is a hack introduced by several MB makers to satisfy a market demand...based many clueless OCer's understanding of basic electrical engineering concepts..specifically, the concepts that are behind vdroop in the first place. With LLC enabled, transient voltage spikes when loading and unloading the CPU (games and benchmark programs, specifically) introduce spikes well outside the range of the limits tolerated by 45 nm chips. CPU degradation can be either a quick or slow process, depending on the base Vcore setting of the CPU (which is typically, much higher than VID on overclocked systems). Either way, LLC will rapidly reduce the life of a CPU by introducing massive transient overvolts every time the CPU voltages change in a dramatic way (gaming, for instance). All the MB makers did was to formally introduce a way to implement the infamous 'vdroop pencil mod' into the BIOS, requiring the clueless user to actually do it himself. So, the warning about LLC (and vdroop mods) has been there for a long time. If you burned your CPU using it...it is your fault. Caveat emptor.
