good point
I detect, on my 9900k codexi these.
I have desable the AVX since windows use avx instruction. No explanation since i avx there is o drop
Now. windows also make these droop. have being playing with the LLC and is consistent
I have now level7 and still drops from 1.30 to 1.28/1.27 volts (5.0ghz)
Try these with a normal oc and with S3 disable. Odd but expected.

I adjusted a bunch of times while I was dialing in my OC. The issue is that it drops below the manual setting of 1.264v to 1.248v with LLC6. That's Vdroop and LLC6 overvolts so I'm not sure what the issue is. Going the other way, with LLC5 and setting manual voltage to 1.3v, it will idle at 1.312v and it will drop to 1.28v under load. The only other time I've seen it droop to 1.248v is if I keep the LLC at 5 and set the manual vcore to 1.29. It then idles at 1.28v and drops to 1.248v underload which is unstable. That's the only time i've seen it drop that low other then when it's on stock at 1.25v
Before any of this I had it at 4.6ghz stable at 1.32v LLC5 -> 1.280v load 1.304v average. I set AVX to -2 to try it out and saw that the CPU was dropping to AVX speed even when there's no AVX being processed, so I turned it back to auto. I then read that there is some sort of bug with AVX and they're going to release a bios update at some point. The 4.6 OC was a little too warm for my taste so I backed it off. It's really after I tried the AVX thing that I saw this start happening. AVX only drops the clock speed though, not the voltage as far as I know. This also doesn't happen all the time. It's just ever now and then I'll do something trivial and the voltage will hit 1.248v
I've been trying to figure out where I can safely OC for about a month and a half now and I'm just wondering if all this stress testing maybe has borked something either with the bios or the PSU. I have a mid tier AIO so it doesn't have a high enough TDP for anything above 4.6ghz 1.3v with LLC5 (vdroop) I can't get an answer out of the HWinfo guy about how accurate the program readings are and ASUS refuses to answer questions about overclocking which is hilarious. I just really hope someone has a definitive answer because I'm reluctant to do anything right now until I figure this out.
Thanks for your replies.
