I'm new to pc building (this is my first build) and need some suggestions for overclocking. My system specs include: evga g3 1000w psu, asus maximus x hero mobo, intel core i7-8086k cpu, dark rock 4 air cooler with 135mm fan (MX4 thermal compound), 16gb corsair lpx 3000 MHz ddr4, samsung 860 evo 500gb ssd, wd black 1tb hdd, evga gtx 1070 sc black edition GPU, 3 corsair sp120 intake fans, 1 corsair sp120 exhaust, and one corsair ml120 pro exhaust mounted on top. The build is in a corsair obsidian 500d. This pc will be used to train neural nets using tensorflow; I will upgrade the GPU to a Titan V in a year or so. I followed der8auer's 8700k overclock guide on youtube and obtained a 5GHz overclock on all cores with a vcore of 1.32 and a cinebench muilticore score of 1615 peaking at 75c. I ran prime95 but the temps shot up past 80c running 6 threads and cancelled the test. I'm afraid that, while the dark rock 4 is quite a beefy cooler, I don't have the cooling capability to run a 5GHz overclock 24/7 and under full load when running tensorflow. I currently have a 4.8GHz overclock on all cores with an AVX of -3 and vcore of 1.27 that runs cinebench at 68c and a multithread score of 1550. Adaptive voltage is on as I am using the Windows 10 balanced power mode. At the current overclock it idles at 31-34c with the cpu fan at 50%.
Is there a way to safely run a 5GHz overclock at a vcore of less than 1.33 without delidding or changing my cooler. Are these values normal for the 8086k? What bios setting do you recommend? How low of a vcore would you expect for 4.8 GHz on an 8086k?
