I'm messing around with the OC that the asus auto tool gave me, and I'm getting some overvolting that I didn't expect to see. I've got the CPU voltage set to 1.25 in the Asus AI Suite, with LLC on regular, yet under load CPUZ is reporting that it gets up to 1.33 volts, or 0.08 higher than it should be. I just tried the LLC on Extreme and it shot up to 1.45 volts under load. What's the deal with this and how can I prevent it from frying my system as I go higher?

p8p67 overvolting?

Yeah, I have a P8P67 Pro, and had it act a little strangely too, when I tried to set the voltage as an offset of +0.1 it ended up being around 1.0something V at idle, and 1.4v at load. I changed it to be set directly at 1.3v instead of an offset, with LLC on auto, and that seems to have put the voltage relatively stable at around 1.28V
I tried changing the LLC from auto to high, and it made my voltage drop down to 1.24v when I put it under load, where it promptly froze and gave me a blue screen, so it's a bit strange it seems.

Same here. I have voltage set to 1.31 and cpuz is reporting it at 1.288 but it drops all the way to 1.25 with LLC set to high.
When I have voltage set to offset I get an instant freeze as soon as I start p95.

I advise you all read the overclocking guide I have posted.
Remember droop is part of the standard Intel VRD spec. If you want to try and approximate the best LLC counter (option) with voltage when under a heavy unrealistic synthetic load like prime I would advise Ultra High. This will generally give you what you set in voltage to what is present when under load
Example 1.4 – 1.375 to 1.400 when under load (when 1.4 is in the UEFI for voltage along with Ultra High being selected for LLC)
Keep in mind that if you use a manual voltage option you default vid is always going to be higher than it would be should you use offset.
Auto Tuning by default uses offset as well regt LLC ( which is actually 0 % ) so you will see core voltage drop when idle along with frequency and rise up when under load and more voltage is need to sustain the overclocked frequency. The adjusted voltage value was automatically enter during the auto overclocking process to a + % of primary offset VRD voltage.
Hope this helps. Please enjoy the rest of your day.

i manually set voltage to 1.3V and LLC to Ultra High. cpu-z is reporting 1.28V under load with IBT, and 1.296V at idle. seems reasonable to me.
