Also, I guess no one cares about the Memory Latency Calculations I have posted twice now, I thought it was interesting stuff... Oh well.

Spoiler!
I did see it thanks man - I have something similar from days before calculator - I just had a read and kind of take your experience on-board - we all have such different experiences and different calculations. It helps to give me ideas I might not of thought of. So thanks for useful post - the more information we share the better things get for alll of us...

I passed out in front of computer while doing OCing. 5.30am and I need my bed!

I bought me another Aquaero XT 6 to make this no longer an issue, but its a shame because I like I using the UEFI to control fans, save for this BS issue, and the stupid fans at 100 Percent once getting hotter than 75c issue.
Seems different for everyone doesn't it? I've literally had it twice - and my problem is the temp that AISuite (and bios right?) uses (WMI) to control the fans gets stuck, so although the fans were on, they just sit there at idle 39C setting of 900rpm - NOT enough! I leave my machine running all the time as well. Not happened since installing 2606. I had it happen on 2501 and 2602.

It would drive me mad if that happened every day!

The voltages in @lordzed83 profile seem like they might help me, not run enough tests yet but, so far they seem beneficial - but finished testing for tonight!

Also, tried to find out what default VCore is - by adding offset .00625 which got me something like 1.012v Is that right? Is default VCore really around 1.0xx Volts?
The default Vcore is based on VID so changes depending on the Clocks which under Auto Ratio changes and is based on FIT calculations. So everyones default Voltage will change because FIT is chip dependent.

oreonutz Did anyone happen to see my Memory Latency, Bandwidth, and Timings Calculation post? I posted it the other day and I don't think anyone noticed it. I thought it was super interesing. Posted again below.

Spoiler!

Even if vid drops to 1.263 from 1.344 underload like in the pic i posted above, Vcore stays the same always in hwinfo under load or no load. Meaning cpu is always getting 1.35v which i set in bios. In which case LLC has no use when setting manual vcore in bios? Am i correct?
So you monitor Voltage with the "CPU Core Voltage (SVI2 TFN)" or "CPU Core Voltage" under the ASUS WMI Tab in HWinfo, Then you can gauge how bad your Vdroop is by seeing what your Reported CPUv is before putting the CPU under heavy load, and then seeing what the CPUv drops to Under Load. Don't use RM to monitor Voltage, all RM reports is VID, and that is not Accurate at all. Use HWinfo to monitor the Actual CPUv, and again vdroop is just the Loss of Voltage while under load. Hope that helps.

LLC is used to compensate for this Vdroop by pushing the Voltage up while under load, the problem with using too much LLC to compensate is that the higher the LLC the Higher the Voltage Overshoots when a load is finished. Unfortunately HWinfo does not report fast enough to be able to see the Overshoot, so you will never see it unless you put a high end Voltage Meter or Oscilloscope on the board, then you will see the higher the LLC the Higher Your Vcore will spike when leaving a heavy load, this has the potential to hurt your chip over time. However if you have great cooling you should still be ok, its just something to keep in mind. This is why generally most people recommend never going higher then the Second Highest LLC. I live on the dangerous side so I tend to use LLC Level 5 when trying to find how much Voltage is needed for a given Clock, and then will usually back off the LLC after and then just increase the Voltage by about 10 to 20mv, and call it a day.
