I have decided to reduce the CPU VCore to 1.4v applied (I will measure real VCore at the output capacitors), and see how high I can validate. On most boards it's 5.0. I have also decided to add real voltage levels compared to what is set for all motherboards, if they don't have voltage read points I will mark where I read the voltage.
The Fatal1ty Z170 Gaming-ITX/ac is doing 5.0GHz just like the high-end motherboards, which isn't surprising at all.
I tested stability at 4.8GHz CPU, 4.2GHz Uncore, and 2666MHz on the memory with 1.4v on the VCore. I am using HandBrake to transcode a 4GB video, and it is very telling since it pulls all cores to their maximum frequency and load. Handbrake is good for a quick stability check, plus I get a log of the encoding speed and the number of errors. It is very easy for the queue not to finish all the way and just error out; it has to proceed without errors to finish.
I have measured VCore LLC on the board's first three LLC levels and indicated where I measured the voltage from on the back of the board.
Test 1: 4x4GB (16GB) Corsair Dominator Platinum 3200MHz C16
The Corsair Dominator Platinum is kit meant for X99, but it worked fine on this Z170 motherboard, granted only two DIMMs were used.
Test 2: 2x4GB (8GB) G.Skill Ripjaws V 3600MHz C17
The Ripjaws V kit doesn't work on all motherboards, but it worked perfectly on this one.
Test 3: 2x4GB (8GB) G.Skill TridentZ 3733MHz C17
The Fatal1ty Z170 Gaming-ITX/ac passed this test quite easily.
Test 3: 2x4GB (8GB) Corsair Vengeance LPX 4000MHz C19
The Fatal1ty Z170 Gaming-ITX/ac worked perfectly with this 4GHz kit; that was unexpected considering it only works on select overclocking boards at this point.
