CPUID recently released their latest CPU-Z version which 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 5.0-5.1GHz. 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 Z170X-UD5 is doing 5.1GHz.
AIDA64 is a useful program to grab settings, run benchmarks, and do stability testing. However, its stability test isn't the most stringent, especially if you don't increase the allotted memory size, so I have decided to test stability another way. I am using HandBrake to transcode a 2GB video, and it is very telling since it pulls all cores to 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.
While there are three settings for LLC (Auto, Standard, and High), "Auto" and "Standard" produce the same results. The "High" setting is actually quite good, and it provided a tiny bump in voltage during loads. I measured at the output capacitors, since it's easy for me to reach the back of the motherboard when it is powered on (I cut out the back of the case), but there are voltage read points which will differ from capacitor readings by only a few millivolts.
I have decided to also change some things for the memory section. Clocking standard XMP has become easier, and ever since launch, memory performance and overclocking has gotten better too. I have decided to expand the overclocking tests to the following:
Test 1: 4x8GB (32GB) Corsair Vengeance LPX 2666MHz C16
I added a second Vengeance LPX kit to my previous memory test for 32GB of memory. This test is to see if the board can apply XMP meant for two DIMMs to four DIMMs of the same make and model, and the Z170X-UD5 booted and applied the settings without issue.
Test 2: 4x4GB (16GB) Corsair Dominator Platinum 3200MHz C16
Here I am using a kit meant for X99 on Z170, this is a fast kit at the speed more people will run below for 24/7 operation. The board handled this kit without issue.
Test 3:2x4GB (8GB) G.Skill Ripjaws V 3600MHz C17
This 3600MHz kit doesn't work on many boards, most overclocking motherboards operate it fine, but the board has to be tuned for it. The Z170X-UD5 isn't an extreme overclocking board and it wasn't able to easily boot this with XMP (I am told it will be fine with a future BIOS update). The settings would take, but it wasn't very stable, so I ended up setting 3466MHz instead, which ended up giving me enough stability.
