i7-6700k
32GB 2400mhz DDR4 (16x2)
Asus Sabertooth z170 s
Windows 10 Pro
HWMonitor 1.29.0

UEFI/BIOS from Default:
XMP RAM Profile
CPU Core Ratio => Sync All Cores => 46
CPU Core Voltage => Adaptive / Turbo to 1.300V (originally set to manual for several days of learning/testing)

I think I am at a pretty stable configuration, after several days of trying different things and stress testing. 4 hours RealBench and 4 hours Intel XTU, VID as read thru HWMonitor and CPU-Z remained steady at mostly at 1.304V with a max of 1.315V with temps max in the mid-60s.

First, does all this seem reasonable? About 1.28-1.33V seems to be the spread for 46 multipler with the 6700k.

Second, I have googled the crap out this and cannot find a good answer... What is IA under the CPU Voltage in HWMonitor?

It is listed under the tree:
MyPC => Intel Core i7 6700k => Voltages

The values under Voltage tree are for VID, IA, GT Offset, LLC/Ring Offset, System Agent Offset.
VID shows 1.304V value, 1.304V min, 1.315V max (I reset max/min when I started stress test)
IA shows 1.331V across the board.
Rest are +0.0000V

I have seen posts that explain very high IAs (3.+V) and also IA offsets, nothing seems to fit. The values for IA only appeared (or I only noticed it) after I set power to adaptive. I am almost thinking it is my 1.300V set in the UEFI/BIOS plus the additional Auto Offset, like a top maximum voltage. I should probably stop letting my stupid show... Any help is appreciated.

I also have a 6700k, I got 4.5ghz at ~1.305v. Set to manual.
So all your settings seem reasonable.
At lower voltages I usually experienced a crash in GTA V of all things due to instability, even though I had stress tested it for ages. So for stress testing any workload is a good test. ;)

As with IA. IA is the internal sensor placed onto cpu cores. From what I can gather, it is the extra voltage applied due to your adaptive setting. Say you set your adaptive to 1.3v, however due to adaptive that may hit 1.3250v. So you are correct as it is like an auto offset. That's all I can explain on IA ;)

-good luck
