VCORE won't change
VCORE won't change
Motherboard: Z170X-Gaming 3
BIOS: F20 (the newest version).
Attempting to overclock the I7-6700K has proven challenging, as it struggles to even reach 4.3GHz in Prime95. Despite adjusting VCORE settings in the BIOS, changes aren't reflected during startup. When accessing the BIOS, saved configurations appear intact, but system monitoring shows voltage fluctuations between 1.25V and 1.35V under full load. Many users suggest using fixed or manual mode, though this option isn't available in my BIOS. Could you have any ideas?
The video is about the CPU's voltage request, specifically the Vcore value indicating the actual voltage received by the CPU. Focus on the Vcore readings rather than the VID. Ensure you are using prime95 version 26.6 or tools like AIDA64 or ASUS Realbench. For Gigabyte, enter the desired voltage in the core voltage box during manual mode.

VID should reflect the actual voltage the CPU receives, not the VID value.
Check vcore readings instead of VID.
Use prime95 v26.6 or AIDA64/ASUS Realbench for accurate testing.
For Gigabyte, set the desired voltage in the core voltage box during manual mode.
Thanks.

VID refers to the voltage request for the CPU, specifically the core voltage it actually receives. Focus on the vcore readings rather than VID. Ensure you are using prime95 version 26.6 or alternatives like AIDA64 or ASUS Realbench. For Gigabyte, enter the desired voltage directly in the core voltage box during manual mode.
Thanks.
What voltage do you suggest for a 4.7-4.8GHz setup with Corsair H100i GTX? Consider the stable voltage your CPU maintains at 4.7GHz and your preferred maximum temperature. Since your VID ranges from 1.25V to 1.35V for 4.3Ghz, it's unlikely you'll exceed 4.7Ghz without exceeding safe limits. Begin with 1.3V and test the corresponding GHz stability.

Choose a voltage that matches your CPU's stable range at 4.7Ghz and your preferred temperature.
Given your VID range of 1.25v to 1.35v for 4.3Ghz, reaching 4.7Ghz without exceeding safe limits is unlikely.
Begin with 1.3V and test the stable frequency at that voltage.
I found a stable 4670Mhz at 1.44V with an average temperature of 85°C.
You're weighing options: using high cooler performance, keeping voltage unchanged, or lowering it to around 1.4V for about 4500Mhz.
Personally, I think 1.44V is a bit too high for regular use. 85°C feels too intense, I’d prefer it around 70°C. Don’t assume every i7 6700k will reach 4.7Ghz with lower voltage and temperatures. Thanks a lot, you really assisted me!

By the way, after some testing, I realized my i7 6700K struggles with stability at 4.7Ghz, even with top cooling and 1.445V. I might see a blue screen after about ten minutes. But with just a 100Mhz drop to 4.6Ghz and 1.35V, I didn’t get any issues for over half an hour. I should try it longer to confirm, but it seems stable enough. How do the results change with only a 100Mhz reduction and lower frequency?
Also, I should note that English isn’t my first language, so I might have misunderstood somewhere.
Silicon lottery. Not every i7 6700K is identical. A 4.6Ghz performance around 1.35V is typical for an average model.

What would the results be if we reduced both voltage and frequency by that much?

OK. And the final question: I set VCORE to 1.35V, but now it displays less than 1.35V when idle and below 1.3V during full load.
