I tried to find this option in BIOS and nothing. BIOS Is updated to latest UEFI version. When I add 1.370V to VCore, on iddle I've 0.911V. On full load I get 1.308V. On Prime95 Crashes, on OCCT crashes, on IBT crashes. When I add voltages for example 1.375 or 1.4V on iddle I get 1.375 or 1.4V, on full load 1.32 or 1.36V. So high vdroop.
My multiplier Is 4.4GHz.
VTT 1.050 i set 1.080
PLL 1.800 i set 1.740
PLL overvoltage Disabled
Turboboost Disabled
HyperThread Tech Enabled
c1e Auto
c3c6 stare Disabled
cpu thermal monitor Disabled
eist Auto

Very strange overclock on this Mobo.

I think its called Multi step Load Line "AKA" Load Line Calibration.
In advanced Voltage settings.

Which version of bios do you have?
I got latest U1E version of BIOS. And BIOS doesn't have Load Line Calibration, Multi Steps Calibration or LLC... I dont know what to do. Only stock voltages and 4.2GHz Is stable.
I read somewhere that this Mobo wants more voltage for overclock. This one have 16 power phase design...

Try using older bios like F10.

Which revision of motherboard? It should say somewhere on motherboard by bottom left aside of the screw.

Try doing CTRL+F1 in bios main screen (usual hiding stuff from gigabyte since years)
Thank you, but I dont know revision. On HWinfo i read Intel Z68X Cougar Point chipset and I guess it could be rev 1.
In BIOS I tried to press alt & f1 and nothing. I will try install BIOS on f10.

I also recently looked through a Gigabyte Z68 manual on a different board, same information, and he also couldn't find LLC. I wonder if there is some logic to getting it to display? Maybe there is a prerequisite setting?
I just tried to downgrade bios to f10, but it says ''Invalid BIOS image''. I did it through Rufus, add bios file for my mobo and it said the same. I renamed bios file into bios.rom, bios.bat, and still nothing. This uefi bios is sobuggy since first day of install. Mobo only accept my saved bios file.
Does anybody know how to fix this ''Invalid bios image''?
