Max PLL voltage for Skylake
Max PLL voltage for Skylake
can't locate it in the Intel specifications or online results because I'm limited to BCLK overclocks, which affects my stability.
I don't believe using an OC base clock is a solid approach. I'm not sure how OC Formula BCLK works, but it seems other Z170 PCHs will be impacted by high BCLK presets. You should begin with 0.0X, save, and exit, then run the stressing tool like Prime95. When you reach auto shutdown ~ POST ~ Windows boot ~ BSOD ~ freeze screen or stuttered, increase by 0.01 from your previous setting. If your preset shows any of these symptoms, reduce it by 0.01.
Auto shutdown = component exceeding PSU wattage rate
POST failure = wrong voltage adjustment for CPU/RAM/Chipset
Boot = compatibility with speed changes
Freeze/stuttered = throttling on CPU/RAM/Chipset
There’s no way to precisely determine the correct PLL voltage...
Tell me about your motherboard and its BIOS, as well as the CPU cooler and fan specifications.
What is the motherboard model and BIOS version? Which CPU cooler is used, and what are its fan settings in RPM? The Z170 OC formula p2.20 uses Coolermaster hyper 212 evo; is performance limited by temperature?
I don't think OC base clock is a good idea, I'm not aware of OC Formula BCLK arranging but consider the fact that other Z170 PCH will be affected by high BCLK preset then you should start by 0.0X > save and exit > run stressing tool such as Prime95. When you pass auto shutdown ~ POST ~ windows boot ~ BSOD ~ freeze screen / stuttered then increase by 0.01 from your previous setting, if your preset encountering one of symptom above then just step back by 0.01.

There're no way to exactly getting what's the right PLL voltage for your build, you can max out cooling capacity first, I use i7 6700T myself with 2133 DDR, pretty fast on encoding despite lower speed than 4GHz siblings. You only need OC on certain task, putting your CPU on OC state will fasten power related components (capacitors, chokes, MOSFET, ICs) to degrade without sufficient cooling.
