Need assistance with the I7 6700K and Gigabyte GA-Z170XP-SLI ATX?
I have an I7 6700K and a Gigabyte GA-Z170XP-SLI ATX. I'm just starting out with overclocking and unsure how to manage or adjust the maximum CPU voltage. I've tried changing it in BIOS, but the voltage keeps going higher than intended. Also, using the Gigabyte Extreme Tuning utility didn't help stabilize the setting.
Notice the core voltage closely. A slight rise beyond the target is typical. I configured mine at 1.420, but under load it climbs to 1.432. To fix this, apply an offset voltage. With a 12mV shift, setting an offset of -0.012v will maintain the voltage near 1.42 instead of 1.432. In your diagram, the increase matches what I experienced.
There should be an adjustment near core voltage that allows manual override.
To begin overclocking your CPU, change the voltage to manual and set it to 1v.
Then adjust the multiplier for all cores to 40x.
Launch Windows and perform a stress test for 10 minutes while monitoring temperatures with HWMonitor.
If successful, increase the multiplier to 41x and retest.
Repeat this process until the system crashes or fails to boot into Windows.
After that, increase the core voltage by 0.025v and test again.
Keep raising the multiplier until instability appears, then adjust the voltage to achieve your target overclock.
For a stable 24/7 overclock, avoid exceeding 1.39v on that chip.
Once you reach the desired setting, run OCCT for 30 minutes to verify stability. If the system crashes during testing, further raise the voltage. If it remains stable, congratulations on your overclock.

After achieving the desired setting, run OCCT for 30 minutes to verify stability. If the system crashes during testing, further raise the voltage; if it remains stable, you’ve achieved a successful overclock.
Oh wow, you're trying to change the settings from XTU, but you keep insisting on overclocking in the BIOS.
KeelinTy:
You're getting mixed up about XTU settings. It's confusing when you see warnings about core voltage exceeding BIOS limits. VID stands for voltage at data input, which is important to monitor but not always ignored. Just check the specs and adjust accordingly.

Ignore VID. You should focus on Core Voltage. If it only slightly exceeds the set value, that's normal. I adjusted mine to 1.420 but the voltage rose to 1.432 when under load. To fix this, you need an offset voltage. With my setup, I used a -0.012v offset so the voltage stays around 1.42 instead of 1.432. In your picture, the 12mv increase matches what I experienced. Thank you for the clarification—I was confused about whether VID affected the reading.

To fix this, you must apply an offset voltage. With mine, the difference is 12mV, so using the same offset (-0.012v) will maintain the voltage at 1.42 instead of 1.432. In your diagram, the increase is shown clearly, so the offset should match what I have. It’s unusual that voltage drops under load—it’s a protective feature because when current increases under load, power (A × V) must stay stable.
