My 5960x does fine at LLC 6 for up to 4.5GHz but requires LLC 8 for >4.5GHz. I've always looked for 'flat' vcore in previous gens, and now yes flat VCCIN. As the anandtech article states, too high LLC causes problems when coming out of high load. But then again this issue is now well understood - so just reduce your LLC and bump vcore up if it happens.
Regardless, I don't think I've ever seen anyone document/provide proof that LLC alone has killed a CPU. It was always a combination of LLC and high voltage... Where the voltage could have killed the CPU on its own.
Voltage is meaningless regarding "kill", current kills (and only current can increase temperature). Voltage is only the potential that current (amps) is delivered at, when a "work request" is made. Sure, LLC does not kill a cpu - but transient spikes degrade them over time, This is why LLC continues to be programmed into bios - only on those rails subject to this effect (it's just the physics of current change at constant voltage). With the VR on x99, we have access only to vccin in this regard, all other voltages are stepped appropriately on the die.
Likewise, I've never had a cpu or overlcock for which I could only achieve the needed voltage by defeating vdroop. Unfortunately what we see as "flat" is not in fact, flat.
I just have a different approach: Idle voltage is meaningless, so when needed I just raise the voltage (VCCIN for this generation) and allow vdroop to mitigate the transient-induced voltage spike. Intel describes the effect in their spec sheet for this generation.
Certainly there is "art" or personal preference in this. I prefer to allow some vdroop.

so, the "MAXIMUM" column represents a 15 minutes run of RealBench...
the UEFI screenshots, are my current settings... any sugestions?
No suggestions if it is running the way you want it to.
