I'd say that is a victory for LLC3.
Is there anything to fear from LLC3 in light of the above result?

If you look at CPU Vcore you won't see the spikes that the VRMs are generating. Raja@ASUS posted some shots from an oscilloscope a 50 pages back or so. Again, as said a couple of times here already, The Stilt, elmor, Raja are all advising "leave LLC on auto, adjust Voltage until stable".
A higher LLC will not immediately damage any components, but will increase wear on those and thus decrease durability. Your choice.

Update : settled on 1.45 voltage for 4 ghz LLC on auto. Will continue stability testing by playing all my games. Will report problems if I have them.

Wait a minute, please. While I think LLC 5 is probably going to make your motherboard last 10 years instead of 20, I see nothing wrong with LLC 3 (which helps stabalize things a lot). I'd rather be at LLC 3 and putting 1.45v into my cpu than at LLC1 (Auto) and putting 1.5v into the cpu to get it stable. And besides, WASN'T this motherboards main selling point it's ridiculous overkill on quantity and quality of VRM and capacitors, ect. for the LN crowd? I find it hard to believe that a motherboard designed to take the highest of beatings can't handle LLC 3 for 10-20 years. I have other crappier Asus motherboards running LLC 3-5 for 10 years now. If LLC 5 was really that damaging to the motherboard, IT WOULDN'T BE IN THE BIOS! Just use common sense. It seems that reasonable 24/7 numbers are CPU 1.45v, LLC 3, VSOC 1.2v, dram 1.4v

LLC isn't going to hurt the VRMs hardly at all. Your point is valid. Your CPU on the other hand may not be so lucky. VRM control loops are only so fast and overshoot isn't doing the CPU any favors. It's helpful to look at Raja's scope shots and back off your nominal voltage accordingly.

Drop the memory frequency and raise the BCLK.

Last paragraph in the OP:
"Note that these results are for reference only and should be taken as an indicator but the trend-line is clear. 2666 and above ratios can only use even CAS Latency numbers which is why it's running 2933 @ 14-13-13-13-36. The last 3466 CL14 data point is using the 2400 DRAM ratio but at 144.4 MHz reference clock which yields tighter sub-timings. These are all attainable 24/7 memory frequencies (3466 might be a stretch on some systems). Screenshots available here for verification and comparison."

You'll be pulling the same volts irregardless to get the CPU on full load. And while at idle, the voltage might "seem" higher, but without much current flowing through (since you're at idle vs full load), a higher voltage will not have much effect. Further, you'll actually have less voltage applied at idle anyways assuming you're using p-states.

And as someone pointed out above, its not the motherboard you should be concerned about, but the CPU.

Hammer to crack a nut....

I'm hoping with a few months development things like this will be ironed out. When ram fails to train, things just seem to fail catastrophically in a cascading manner after one bad boot and then the hidden/lost/stealth saved values pop up and its anyone's guess what happens next. The galaxy of different Q codes that ensues is quite comical.
10 flashbacks later and yer up again...

All at stock CPU mind, all my CH6 madness seems to stem from trying to get the RAM to run at a sensible speed.

LLC2 I don't think is harmful. LLC3, maybe. I haven't tried above that nor do i want to..... yet.

And you have a point there. If LLC was REALLY harmful to use and caused extremely higher rates of CPU/VRM degradation, you would think they would say so with note in Bios and AI suite. Its possible that it is somewhat of an over-exaggeration and like you said will make your board/cpu last 10years instead of 20 years, by then we will have probably upgraded anyways. Though in the end I don't think its so much the VRM's at stake, but the CPU voltage overshoot after loads are released that will do the real harm. After all they said VRM's can take a beating on this board.

But maybe they assume that everyone knows what every option in bios will do and their cons redface.gif. (people should assume!)

I used the same BCLK and memory frequency as Raja. This does not lead to Tcl timings as low as in Raja's screenshot.

I just tested the 2666 memory frequency, my tRC dropped to 63.
