Just a note for Gigabyte Z270X motherboards:
I looked at what you said you did to get to 5.0GHz. You probably did the following and did not mention it, so, I will state what I did on my Gigabyte Z270X-UD5. [I purchased my parts at Micro Center and the best RAM they had was Dominator 3000 [16GBx2 kit] 1.350v.
While I could overclock my CPU to 5.2GHz, for the most part I needed more Vcore for stability with the required 1.350 volts for the RAM to function at 3000.
RAM at 1.350 volts, BCLK Adaptive Voltage: Disabled, and CPU LLC to Turbo:
At default speed my Vcore is 1.335 volts
4.8GHz Vcore is 1.370 volts
5.0GHz Vcore is 1.470 volts
RAM at 1.20 volts at 2400 [for now, the build is new] and:
BCLK Adaptive Voltage: Disabled, CPU LLC to Turbo, Intel Speed Shift Technology: Disabled, Voltage Optimization: Enabled
At default speed my Vcore is 1.290 volts
4.8GHz Vcore is 1.360 volts [might get this lower, not finished here]
5.0GHz Vcore is 1.380 volts
5.2GHz Vcore is 1.445 volts [I have not stress tested yet, however, it is stable in games - although, too hot]
For cooling I am using a Noctua NH-U14S, not the most uber, however it is good and fits my case. I need to delid my i7 7700K and put Thermal Grizzly Conductonaut on the CPU die and IHS [I will use Thermal Grizzly Kryonaut on the outside of the CPU IHS for the cooler]. I have the Kryonaut and the Conductonaut should be here Monday 6 March 2017.
I need to delid and use liquid metal to drop temperatures before I bench stress test this CPU on air at 5.2GHz, and have read after a delid and liquid metal, some people have had over 20 degrees C drops in required CPU Package Power at the same Vcore used, so, if lucky I might get away with a little less Vcore after the delid.
Thank you for your article. http://www.hardocp.com/article/2017/01/26/intel_kaby_lake_i77700k_cpu_overclocking_followup/
