Is this typical for an i7 6700k overclock?
Is this typical for an i7 6700k overclock?
I recently increased my 6700k to 4.4gzh with fixed core V at 1.25v and an offset of +0.025. I also enabled c states and disabled EIST via BIOS. At idle, my core voltage reads around 1.248v (which seems accurate for my OC settings), but during Prime 95 stress testing it drops to 1.216v. Can anyone clarify what’s happening?
You should boost your Vcore slightly and see if it works better. Have you checked your current stock bios? The 1.25 value is suitable for Skylake, but with a 4.6ghz at 1.29V and an LLC setup, it might fail due to increased power demands. Give it another try and run a few more cycles until stability returns.
Eximo :
Load Line voltage droop is quite normal. The BIOS should include a Load Line Calibration option, which compensates for the droop caused by load changes.
If you're not seeing crashes, it probably isn't a major issue.
The problem I'm facing is actually crashes—tried Counterstrike Source 1080p at 4.2ghz with identical settings and still experienced crashes.
Any advice on resolving this would be appreciated.
Thanks.
Some notes.
Vin or Vinput or CPU Voltage should be around 1.6-1.8 volts. This is the voltage coming from the motherboard VRMs to the CPU VRMs. 12V down to 1.8 volts for the CPU core voltage, and other internal CPU voltages. Raising this can increase heat on the motherboard, but it’s needed for higher overclocks. Try adjusting a bit and observe the results.
You already know about the Vcore.
LLC can significantly improve stability with minimal changes.
Monitoring CPU thermals is important. They should stay below 80°C during regular use; if they exceed this, cooling improvements or lowering the Vcore (possibly slowing the clock) are likely needed.
There are many overclocking guides available—check them out.

That one mentions a higher CPU voltage, but I’d need more research to confirm. (The goal is usually maximum speed and longevity, not just short-term performance)
You must locate the Load Line Calibration option in your BIOS and adjust it to either the maximum or the second-largest value. Eximo provided the information, but didn't explain how to apply it. Your board features seven levels of LLC, and you've configured it to level six.
I formed my suggestion based on the fact that the previous three boards required the second-highest levels to avoid droop.
You should boost your Vcore slightly and see if it works better. Check your current stock bios—1.25 is suitable for Skylake. You're running at 4.6ghz with 1.29V, using an LLC. It might be crashing because the overclock demands more power. Give it another try and run a few more cycles until stability returns.
Thank you for the guidance, the team is checking if the current configurations hold up. I'm not too concerned about temperatures since my highest reading in the past hour was 61°C. Appreciate your help once more.
