[nextpage title=”First Look”]

Gigabyte Z170X-Ultra Gaming Motherboard (10)

The first impressions are great; this is exactly the kind of board I’ve been hoping for! Finally, a board that ticks all the boxes, simplistic, low key and dark! Sure, that’s been done before, but they tend to be on the cheaper boards, and the end results average. Not here, this has been styled to perfection. The amount of black is immense, and that’s exactly what I and many others want. The silver accents are low key, and don’t spoil the design.


The heatsinks are on that fine line between basic and minimalistic, the decision to keep any colours out, and the design toned down, was the right move. Upon closer inspection, they both feature a brushed finish. The shroud is another welcome addition, sporting a unique honeycomb mesh. Which thermally may or may not help, regardless I like it!

[PCI-E Setup]

Gigabyte Z170X-Ultra Gaming Motherboard (3)

  • 1 x PCI Express x16 slot, running at x16 (PCIEX16)
    * For optimum performance, if only one PCI Express graphics card is to be installed, be sure to install it in the PCIEX16 slot.


  • 1 x PCI Express x16 slot, running at x8 (PCIEX8)
    * The PCIEX8 slot shares bandwidth with the PCIEX16 slot. When the PCIEX8 slot is populated, the PCIEX16 slot operates at up to x8 mode.


  • 1 x PCI Express x16 slot, running at x4 (PCIEX4)
    * The PCIEX4 slot shares bandwidth with the SATA3 0/1 connectors. When the PCIEX4 slot is installed with overclocking x4 or above card, the SATA 3 0/1 connectors becomes unavailable.

2 way SLI and Xfire is supported

GIGABYTE has added lighting in unusual and unexpected points such as the DDR4 slots. The effect is brilliant We also have lighting from the heatsink and down both sides of the board. The LED’s around the PCIE slots will add a subtle under glow to any GPU too. I appreciate their unique take on lighting.

The problem is…what if you don’t like red? Or wanted to change it too blue or green? Sadly theirs no option to do so. A real shame

[6600K Overclocking]


In a nutshell, we have 4 physical cores, DDR4 and DDR3L support, a new IGPU in the form of Intel® HD Graphics 530, the 14nm architecture, and a base clock of 3.5 GHz, which can boost to 3.9 GHz

After so many Z170 reviews, I just want to jump in and talk numbers today. Our  CPU has a limit of 4800Mhz. we hit that target and held stability with no issue.

[Testing Method]

Our test method  uses a large variety of software to determine the results and product award. For your viewing, these are broken down into the following categories

  • General System
  • CPU & Memory
  • Gaming
  • Storage & USB
  • Audio &Networking
[nextpage title=”CPU & RAM Results”]

[General Performance]

We start with a broader view of general system performance and then break it down, as we delve deeper with sub testing, where we can examine key areas.

-[PC Mark 8]

PCMark 8 from Futuremark. PCMark 8 is designed to test the performance of all types of PC, from tablets to desktops. With five separate benchmark tests plus battery life testing, PCMark 8 helps you find the devices that offer the perfect combination of efficiency and performance. It’s the complete PC benchmark for home and business.

The first  test we run is PCMark 8, as we’re also able to gauge an all-around score. This test is heavily affected by all internal components rather than focusing on just one.

We tested a selection of games, and the product delivered brilliant performance, narrowly missing the top spot! For the price point, this is unprecedented,

[nextpage title=”Storage & USB Results”]



Gigabyte Z170X-Ultra Gaming - SATA

Almost top of our charts, with SATA III speed.


Gigabyte Z170X-Ultra Gaming -M2 READ Gigabyte Z170X-Ultra Gaming -M2 WRITE

Both Read and Write performance on the ULTRA GAMING are strong,


We don’t have any USB 3.1  (Gen2 ) devices at the time of testing, so will be focusing on 3.0/3.1 only. Be sure to understand the actual difference between USB 3.0/3.1 Gen 1 & Gen 2. As it’s something that not all brands have explained clearly.To measure speeds we use AS-SSD, with an SSD inside a USB 3.0 Caddy from Startech

The Kingston SSD has a theoretical limit of 499MB/s Write, when hooked up internally to a SATA 6GB/s port. Overheads and such we accept that some degradation occurs when used over USB 3.0/3.1

Gigabyte Z170X-Ultra Gaming - USB

As expected the controllers have matured over time but differences in terms of speed between models, are minimal.



Using the inbuilt network test for Performance test 8. The method is to install the software on two machines, which are on the same network. One acts as a client and the other as a server, a designated amount of data is sent across and then the Min, Avg, and Max transfer speeds are outputted.

Gigabyte Z170X-Ultra Gaming - LAN

The Intel solution proved very impressive.


We use RightMark Audio Analyzer, connecting  “Line out” to “Line in” with a 3.5mm cable.

The Audio quality, as you would expect from GIGABYTE, was fantastic!

[Conclusion – TL:DR]

So then conclusion time, almost a year has passed since the Skylake launch. Availability and pricing weren’t at the same level that we’ve seen in the past. In turn, there just wasn’t that massive surge of interest that we tend to see. Over time the CPU prices have settled, as has the RAM. Back when DDR4 launched, the asking price was hard to digest. Now in mid-2016, they’re almost giving it away. Ok slight exaggeration… on a serious note, the upgrade prices from AMD or even older gen Intel kits, are now at the sweet spot. As with past chipsets, we have the entry, mid and high-end. This product sits at the mid-range level but borrows features from a product of a higher caliber.


Before we even talk performance, we have to chat about the visuals. GIGABYTE has evolved with the growing demands of the consumer; two tones just aren’t enough anymore. Now we can go in so many directions, and they’ve covered all the commons combos. What about those that want a stealthy, subtle or dark look? Well, This product is one of few that ticks the boxes for such desires, before now you’d have to mod heatsinks to achieve anything like this. It feels like I talk about RGB in every review at the moment, thankfully those of use that don’t really want it, have a decent alternative to the ambient red lighting. Granted that almost goes against the whole point of having a black blank canvas, to theme your rig, still it’s appreciated. I’d much prefer a white LED, but red should please most.


The performance was fantastic from start to finish, with no weak areas to be found. Likewise overclocking was easy and solid as a rock, with little effort in the UEFI. For the price tag, I was delighted to see it bettering much more expensive products from other brands!


We would like to thank GIGABYTE for providing the sample, and eagerly await more from them soon!
