The reason why i skipped MSI boards and another reason is i got 2 MSI failed on me due to dead chipset. MSI dont seem to properly secure their chipset heatsink and cause degradation over time.
MSI's Z170 is actually quite fine.
MSI Z170 Gaming M9 ACK LLC (MSI's Hybrid (intersil) PWM implementation):
MSI Z170 XPower LLC (MSI's Digital PWM (IR=international rectifier) implementation):
Sorry for the different tests and inconsistency, I decided to add LLC down the line and I haven't settled on a permanent testing method other than running stresses that I was using at the time of measuring. Either way they are still very useful. Both of these are at 4.5GHz and measured with a DMM at the output of the VRM. I have also started to provide voltage read points for boards that don't have them.
These are my results from using both boards. The XPower has what it needs for extreme LLC. LLC implementations are variable, they are affected by current draw and so they get weaker or stronger as the voltage changes. For Extreme OCing you want LLC that increases VCore on air as that increase will decrease as you increase in frequency and voltage. For air you want a small drop or no drop, and the M9 does just that, M7 and M5 should be identical.
They are well in line with what other motherboards offer. I have only seen perfect LLC on one or two motherboards. However, what MSI has implimented is totally acceptable and it does work.
A few notes on LLC on Z170:
Intel has confused a lot of manufacturers by providing Internal VR Settings with AC/DC LLC and made it available to users. Out of all brands I tested, 2 did not have LLC at all past those internal LLC options, 1 removed those extra options and didn't add LLC and the other added LLC.
You really need to use a DMM.Edited by Sin0822 - 10/17/15 at 11:18pm
