Checking the voltage under the CPU in HWMonitor for quick OC verification.
Checking the voltage under the CPU in HWMonitor for quick OC verification.
New to building/overclocking
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 manual for several days of testing)
I believe I have reached a fairly stable setup after experimenting with various settings and performing stress tests. Over 4 hours of RealBench and 4 hours of Intel XTU (with VID monitored via HWMonitor and CPU-Z), the readings stayed mostly consistent around 1.304V, peaking at 1.315V, with temperatures reaching the mid-60s.
First, does this look reasonable?
The voltage range of about 1.28 to 1.33V for a 46-core processor like the 6700k seems appropriate.
Second, I’ve searched extensively but couldn’t find a clear explanation...
What is the IA value under the CPU voltage in HWMonitor?
It appears under the path: MyPC → Intel Core i7 6700k → Voltages
The values listed there are for VID, IA, GT Offset, LLC/Ring Offset, and System Agent Offset.
VID shows a value of 1.304V (minimum 1.304V, maximum 1.315V), which changed when I started the stress test.
IA is consistently 1.331V throughout.
The other values are around +0.0000V.
Many people have shared posts with very high IA readings (3+V) and IA offsets, but nothing seems to match my setup. I noticed IA values only after enabling adaptive power settings. It might be that my system is set to a 1.300V base voltage in the UEFI/BIOS, combined with an additional auto offset, acting as a top limit. I should probably stop leaving my monitor on. Any advice would be greatly appreciated.
I also have a 6700k with 4.5ghz at around 1.305v, set to manual mode.
Everything looks fine with the current configurations.
At lower voltages I often faced crashes in GTA V because of instability, even though I had stress tested it for a long time. Stress testing any workload is therefore a solid approach.

Just like IA, IA is the internal sensor attached to CPU cores. From what I understand, it's the extra voltage added by your adaptive settings. For example, if you adjust it to 1.3v, it might actually reach 1.3250v thanks to the adaptive change. That’s the only explanation I can offer regarding IA.

Good luck!

For example, if you adjust it to 1.3v, due to adaptation it might rise to 1.3250v—essentially an automatic offset. That’s the only explanation I can offer regarding IA.
