VCCIO voltage specifications for 8086k and Maximus X Hero
VCCIO voltage specifications for 8086k and Maximus X Hero
I used Der8auer's instructions while boosting my 8086k on a Maximus X board:

After configuring the BIOS with "AI overclock Tuner" to XMP and restarting, the board automatically adjusted VCCIO to about 1.34 V, which is quite high. My RAM runs at 3000 MHz with timing of 15-17-17-35. In the video at 8:11 you can see that Der8auer's setup defaults to 1.232 V. Is it safe to keep it on auto and let the board operate at whatever level it chooses? What is the maximum safe setting for VCCIO without causing problems in the long term? For now, I've lowered it to 1.10 V manually.
1.15v is fine if it's needed in your case. Although argued in the forums, it seems 1.25v VCCIO is about the max. No reason to be worried at 1.15v I would think. Also using LLC6 setting myself. IMC voltage can vary depending on IMC quality. This is why XMP sets things on the high side to compensate. Actual Vcore for CPU is fine.
Might need a significantly lower voltage. Currently using 8700k on the same board (AC version), I'm running at 3200 with VCCIO at 1.05v and VCCSA at 1.15v. The stock values are .95v and 1.05v respectively. This has been the case since about a month after the Coffee Lake 8th Gen release. I think XMP is around 1.2v for both, but I've adjusted manually. All standard tests have been completed to confirm.
