After two years of struggle, I finally could boot with XMP 16-18-18-36 3200!
ASUS Z170 PRO GAMING
i5-6600K
Corsair Vengeance LPX Black kit 2x8Gb 3200Mhz + Corsair Vengeance LPX Red kit 2x8Gb 3200Mhz - (4x8Gb - 32Gb in total)
BIOS Version 3805
First of all I reset settings to default. Click EXIT, then "Load Optimized defaults". Save and reset.
Ai Overclock Tuner - XMP DDR4-3200 16-18-18-36 (or something like that don't remember exactly)
BCLK Frequency - 100.00 (xmp set it, and i don't touch)
CPU Core Ratio - Sync All Cores
1-Core Ratio Limit - 42
DRAM Frequency - DDR4-3200MHz
(Timings 16-18-36, frequency 3200 and dram voltage 1.35 - was set by xmp, and i don't change this)
CPU Core/Cache Voltage - Manual Mode
CPU Core Voltage Override - 1.2
DRAM Voltage - 1.35
CPU VCCIO Voltage - 1.2
CPU System Agent Voltage - 1.2
Works stable for me.
for core multiplier x46 i use CPU Core Voltage Override - 1.34 (works for me too)
i tried before next settings and this did not works for me.
CPU VCCIO Voltage - 1.15 (Overclock failed)
CPU System Agent Voltage - 1.15 (Overclock failed)
after 1.2 system booted.
