HI
i have the same cpu and motherboard. i have tried over clocking my board and if i enter the voltage manually (1.4) it doesn't drop down when web surfing (1.38).
if you dont mind sharing what setting you used for your overclocking?

thanks for the help Bazookatooths

b well yes trats is what i saw, now i am at 1.41v vcore and i am bellow 80°C actually it was 73°C and 78°C with aida64 FPU test for about 2 hours and 15 minutes. can i trust in AIDA64 results or should i goo with other program?? ..... i Have MSI Z170a gaming m3 motherboard.

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.

how about at high vcore? more delta on stress vdrop....?

this is my result using crap software.... biggrin.gif



i m using m7 also with 100%

do you think if i using mobo with more vrm n llc option, can my 6700k on the same speed will have less vcore (at max load)...?

thanks for the guide! I just took my 6600k to 4.8@1.456 and 4.7@1.36

it passed 15 minutes of realbench and 1 loop of x264 with max temps at 80 (low profile cooler)

running realbench over night now! cheers!

Where can I find this information for the Hero if you've done this board?

Careful if you read my prev post Under LLC high and adaptive to +.000 my cpu vcore hit 1.55V + on the multimeter but like 1.4 and less on software, even if you use manual your software will report a small vroop on HIGH but the reality is other way around, with manual vcore bios on 1.395 , on load the real vcore is like 1.425V, there no dropp on HIGH with gigabyte it way pass the real voltage you put in.

LLC is way worst with adaptive than manual but I wont use it at all in adaptive without a multimeter with a decent accuracy on manual I wont go past 1.4v in bios that should give you near 1.44-1.45 for real.

Read my previous posts on vcore and multimeter , I did a bunch with software reading and real reading

Interesting ill have to check the voltage manually with the points on the board this may explain why i can get 4.6ghz at a 1.275 volts

In adaptive mode, voltage seems to be more erratic then in manual mode, though I got adaptive mode to run at the same voltage as manual when under load (with the right LLC) it seems to fluctuate more and cause more instability compared to manual. I wanna run this setup 24/7 so I would very much rather do adaptive instead of always pumping 1.45V, anyone have any insights about this?

runing a 6600k with an asus Z170-A btw

Edit:
@1.456v it's slightly unstable during long stress tests, testing now @1.472v as that is the smallest step higher it would go, if someone knows how to lower that voltage gap, let me know! I have been playing around with vcore and llc for hours now

C-states really should not affect stability unless you go too deep in the idling of cores.

That is what adaptive does, by lowering the volatge to all cores.

Please describe "erratic". You mean that vcore is floating under load? What is the idle voltage when you set windows power setting to high perf (min proc state to 100%) and what id the voltage under load?
Adaptive should idle at ~0.8V and load to the value set in bios (and NOT higher - if it does lower the LLC setting to 5). Enable CPU SVID, Set LLC to 5 or 6 on the Z170-A. On this VIII Extreme (bios 0007 - prerelease) LLC=5 gives ~ 30mV vdroop under p95 load at 1.46V
If you are OCing your ram, VCCIO and SA voltage really helped with 3466 from a cheapo 3200 kit (1.212V each) and PCH Core to 1.075V.
6600K, 4.6/4.6/3466c16 With adaptive:
0.005/1.415V (offset/turbo)
VCCio: 1.212V
SA: 1.212V
PCH: 1.075V
LLC 5 (30 mV droop)
VDIMM 1.49V

Stable to p95v28.7, x264, x265, RealBench, IBT, ... etc. Max core temp hits 78C (custom water). While running p95, I scan the entire MB with a recording Fluke IR thermometer, hottest thing are the VRMs (40-45C) and ram sticks 39C.

Guys I am little confusing about amount of power phases on Z170. While ASUS Z170 Deluxe has loads of 20 power phase design, Maximus VIII Hero has only 8 phase. Does this mean Z170 Deluxe will provide more consistent OC?

Btw, anyone tried to measure Vcore with multimeter on Maximus VIII Hero? Is this can be done?
