Overclocking Results

CPU Overclocking

CPUID recently released their latest CPU-Z version that brings some major changes to the much-loved software. One of these changes has made it harder to get a validation at lower stability levels, so it becomes much more troublesome to validate 5.2GHz at 1.5v with every board. While CPU-Z has changed, many motherboards (not this one) don't have LLC. I have to set a higher voltage to compare all these boards at the same voltage. 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 got the readings from.


The SABERTOOTH Z170 MARK 1 is doing 5.0GHz just like other high-end boards.


I test stability at 4.8GHz CPU, 4.0GHz 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 the 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, and 1-3 hours of AIDA is about equal to this HandBrake test, so I am replacing it.


I have marked where you can measure the VCore manually with a digital multimeter, but the LLC is pretty good at level 5, I would stick to level 5.

Memory Overclocking

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


This kit meant for X99 works just fine on the board, which is expected for a Z170 overclocking motherboard.

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


This kit doesn't work on all motherboards. Usually, only overclocking models can even boot this kit by just enabling XMP. The SABERTOOTH Z170 MARK 1 runs this kit at 3466Mhz pretty well but getting to 3600MHz proved troublesome when I tried just enabling XMP. However, if I boot up at 3466MHz and then go into the UEFI and change the multiplier to 3600Mhz, then the system can get into Windows.

This isn't an overclocking motherboard, so I didn't expect 3600Mhz to work at all, but with some tuning you should be able to get it to boot. For stable operation, I would stick with 3466MHz, which seems to be the limit of many boards and not just this one.
