I just have a i5 8600k, a Gigabyte Z370 Gaming K3 and 16GB 3000mhz G.Skill. i Want to upgrade it to 4,7GHz, i do it 2 weeks ago with the CPU upgrade in my BIOS but it doesn't increase the vcore and i was havin Blue Screens so i increase it to 1.275, it rans well but i suddenly started to have Blue screens again playing PUBG. I want to do it with intel extreme tuning utility but i don't know how. I followed a video but when i press the apply button it restarted... I want to do it with IEU but it has a lot of options... if i can do it with the BIOS it will be good to. If anyone can help me i would be very grateful.
