Assuming that you've tried lower voltage, I'm afraid there's no other way to get any lower vCore. Plus, your mobo is the Hero so should be among the best Z370 boards in terms of power delivery, voltage control etc. Every CPU comes with its unique VID (stock voltage), so it may vary from one chip to another. |

Wait, tonight I will share my stable 5GHz OC BIOS settings.Now I am testing an entry-level board.  Will come back to you, so stay tuned.  |

These are the settings that I used last month with the older 0505 BIOS before testing other motherboards. Now testing the 0802, should be better or worse  |

Here are my stable i7-8700K @ 5.0GHz/4.5GHz OC results on two Z370 boards with Prime95 v29.3 running for 3 hours.
ROG Maximus X HERO: 1.280v (Same as APEX) 
TUF Z370-Pro Gaming: 1.328v 
You can see that the TUF required 0.048v more voltage than the HERO. |

Hi bro...so, what do you think about bios 0802? Are you running the same cpu on both prime and hero? Were you using small fft test for both? By the way, the latest version of prime95 is 29.4.5ROG Maximus X HERO: 1.280v (Same as APEX)
TUF Z370-Pro Gaming: 1.328v
You can see that the TUF required 0.048v more voltage than the HERO. Edit: cpu package power on mine is almost 200w running prime95..is it normal? This post has been edited by BroD: Nov 23 2017, 10:39 PM |

By the way, the latest version of prime95 is 29.4.5 I just tested the new 0802 BIOS, so need more time to really comment about it.Edit: cpu package power on mine is almost 200w running prime95..is it normal? But initial testing found that it is better than the old 0505 BIOS, especially in terms of RAM OC. New BIOS allows me to POST easy, run stably at DDR4-4200. Need to test more on this though. With the 0505 BIOS, I had issue getting my B-die kit to POST at DDR4-4133+. 
To answer your other questions: Yes, exactly the same 8700K CPU was used on both TUF and HERO. For Prime95, I always used Custom Blend 1344K min/max 14500MB RAM to stress both CPU+IMC/RAM altogether. Prime95 is very stressful that your CPU power package could hit as much as 180-200W when highly overclocked/overvolted. |

DDR4-4200 CL18 @ 1.35v passed HCl ~500%...
(excuse me for the loose timing, need to go higher then only optimize it) now testing CL17 @ 1.40v
