UPDATED: ASUS Z370 and Z390 Motherboard Series - Official Support Thread. North America
This thread is for sharing experience on the Z370 and Z390 platform and for support on all ASUS boards with these chipsets.
If requesting support, please try to use the following template (or at the very least have rig builder filled out):
Intel specifies voltage limits in their Product Specification Sheets (PDFs). My experience is, running 1.52V vcore is much too high for watercooling, especially combined with transient load line overshoot (micro sec spikes). And as stated in the footnotes of the voltage tables, the 1.52V limit REQUIRES all other conditions are met. So, 1.52V may be "fine" if you never exceed the TDP and IAcc limits. Stick with low to mid 1.3V for 24/7 use.
On the ROG STRIX Z370-I GAMING BIOS page, it lists the 0426 and 5426 versions both updated on 2017/10/20. What's the difference between the two? If I intend to manually OC the system, is one BIOS preferred over the other?
Edit - NVM, Raja answered this question on one of the ROG Forum threads. "The only difference between them is that the 5426 build has ASUS Multicore Enhance enabled by default. Identical otherwise."
