Overclocking Results


CPU Overclocking


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 its 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 Z170 Classified is doing 5.0GHz just like the high-end motherboards, which isn't surprising at all.





I tested stability at 4.8GHz CPU, 4.1GHz Uncore, and 2666MHz on the memory with 1.4v on the VCore. I am using HandBrake to transcode a 2GB 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.




The LLC options are "enable" and "disable", "disable" removes the vdroop while enabled is standard.


Memory Overclocking


Test 1: 4x8GB (32GB) Corsair Vengeance LPX 2666MHz C16




The board passed this test easily.


Test 2: 4x4GB (16GB) Corsair Dominator Platinum 3200MHz C16




The Corsair Dominator Platinum is kit meant for X99, but it worked fine on this Z170 motherboard.


Test 3: 2x4GB (8GB) G.Skill Ripjaws V 3600MHz C17




The Ripjaws V kit does not work on all motherboards, and for some reason doesn't work on this, but the G.Skill 3733MHz kit works perfectly. I am told the kit I have is an early version, so I would buy newer versions of memory if you have that option.


Test 4: 2x4GB (8GB) G.Skill TridentZ 3733MHz C17




The Z170 Classified passed this test quite easily, which is a surprise because it did not apply XMP from a lower-end kit easily.
