CPU fixed voltage, safe?
CPU fixed voltage, safe?
Hello, your recent 4.6ghz overclock on the i7 6700k at 1.36v seems stable. Your idle temperatures range from 26c to 28c and 55c to 64c during demanding games. It's important to assess whether maintaining this speed safely during all times is feasible for your system. Please consider further testing under various loads.
Your OC setup appears sensible given your temperatures.

What percentage can achieve an overclock with a fairly reasonable 1.40v Vcore?
I7-6700K
4.9 3%
4.8 19%
4.7 61%
4.6 95%
It seems you have a solid processor.
I believe it would be best to use adaptive voltage and speedstep.
This will lower the multiplier and Vcore when the CPU isn't under heavy load.
The methods for achieving this vary depending on the motherboard.
If it's consistently set to 1.36 at all times, I suggest reconsidering... it would be better to configure it for maximum voltage offset and allow the voltage to increase with CPU speed during overclocking, then reset it to 800 Mhz. 1.36 is above the typical range for 4.6 Ghz... this usually indicates a higher setting like 4770k.
At idle conditions I'm at 0.71 Vcore and 800 Mhz... when overclocking and AVX is active, the Vcore can spike to about 1.48 volts for a short period, ranging between 1.38 and 1.44 otherwise. Most often it stays around 1.38 during testing with RoG Real Bench, but jumps to 1.41 to 1.44 when AVX is enabled, with occasional spikes up to 1.48. In gaming scenarios, such high values are rarely observed.
Keep in mind that any results from load tests, especially with AVX enabled, show a rise of roughly 0.10 to 0.13 in voltage—meaning a setting of 1.36 could push it to around 1.49.
For accurate comparisons, use RoG Real Bench during testing; many games only load at 40% CPU usage.

Please note, without knowing the original values, it's hard to confirm if temperatures are acceptable.

I believe adaptive voltage and speedstep would be the best approach.
This should lower the multiplier and Vcore when the CPU isn’t pushed.
The methods for setting this vary depending on the motherboard.
When I enabled adaptive mode, I adjusted the vcore turbo to 1.360v with an offset of 0.001v. It functions well during idle (around 0.800v idle), but sometimes the voltage jumps up to 1.40v when running a game! What could I be doing incorrectly? Why isn’t it stopping at the 1.360v setting I configured? My motherboard is an Asus z170-A.
