   Put the BIOS settings "optimized default" (everything on Auto) and be happy . You want to OC your i7 8700 CPU? Why to change CPU voltage at all???

	i7-8700 runs 4600 max turbo on one core or lowest 3200 all cores at Processor Base Frequency . See Intel spec: https://ark.intel.com/products/126686/Intel-Core-i7-8700-Processor-12M-Cache-up-to-4_60-GHz Changing power settings in BIOS and power settings in Windows you can get up to about 4500 (not overclocked) with one core or near 3700 all cores. My 8700k with Intel BXTS15A cooler hits near 75C with 100% load at 4300Mhz and Core volts 1.325 in BIOS auto mode (Z370 Pro4 with BIOS 1.50).

	I'am bought from the first parties. I set more better cooler than box Zalman CNPS 10x optima and in stress test i got temperature ~90 C. I changed many thermal paste and few coolers, but temperature is stay on the same level. After that i'am going to local hw forum and i was told what cpu core voltage 1.460 is not normal and overheat a cpu. In BIOS i cant control the cpu core voltage and nothing happens. And now for z370 pro 4 realised a new BIOS version, core voltage are drops now under stress test to 1.1 and frequency drop to 3800 or something. I need BIOS settings for my system, i try set cpu voltage 1.250 but i STILL CAN NOT SET NORMAL SETTINGS MANUALY ON NON "K" PROCESSOR. Asrock cmon, already past 9 months and i cant solve the problem of. Edited by Barton - 12 Jul 2018 at 8:12pm
