With the introduction of Intel's Z270 chipset, GIGABYTE re-branded its high-end motherboards under the AORUS brand name. Some people have assumed that all of GIGABYTE's models are now AORUS, but that isn't the case. GIGABYTE decided to keep a few of its primary models, and still maintain the Ultra Durable line of motherboards. In the Ultra Durable lineup, the UD5 is typically in the middle, with solid performance and a nice amount of features.
The Z270X-UD5 uses a much different aesthetic design, and in my opinion, is geared more towards power users rather than gamers. When I was working with the motherboard, I realized that GIGABYTE added more workstation features to the motherboard instead of aesthetic features.
For instance, the motherboard has no RGB LEDs or RGB headers. The motherboard seems to be geared towards individuals who want a system they can use for work and play, and now I will give the motherboard a good going over.

GIGABYTE's box design is very similar to that of their previous generation products. Packaging is not as impressive as some of GIGABYTE's higher-end motherboards, but it will get the job done.
![GIGABYTE Z270X-UD5 Motherboard Review 05 GIGABYTE Z270X-UD5 Motherboard Review 05](https://static.tweaktown.com/content/8/0/8064_05_gigabyte-z270x-ud5-motherboard-review.jpg)
The accessory package includes cable stickers, two Velcro cable ties, IO shield, G-Connector, HDMI/DisplayPort dust plugs, two external temperature sensors, four SATA6Gb/s cables, Ultra Durable case badge, manual, and driver DVD.
![GIGABYTE Z270X-UD5 Motherboard Review 06 GIGABYTE Z270X-UD5 Motherboard Review 06](https://static.tweaktown.com/content/8/0/8064_06_gigabyte-z270x-ud5-motherboard-review.jpg)
![GIGABYTE Z270X-UD5 Motherboard Review 07 GIGABYTE Z270X-UD5 Motherboard Review 07](https://static.tweaktown.com/content/8/0/8064_07_gigabyte-z270x-ud5-motherboard-review.jpg)
GIGABYTE offers six 4-pin PWM/DC mode fan headers circled in red. All the fan headers support up to 2A, auto detect between PWM and DC, and can use one of many temperature sensors as a reference. There are two external temperature inputs circled in green. Fan control is provided through the UEFI and Windows, and the UEFI based fan control is good enough that you won't need to use GIGABYTE's Windows software to setup your system.
The motherboard's aesthetics are much different than anything GIGABYTE has offered in the past. The heat sinks and shields are all silver, which is an interesting choice. It has grown on me, and I assume it is this way so that you can use whatever color accessories. The back of the motherboard doesn't have any components on it, which is a good thing.
![GIGABYTE Z270X-UD5 Motherboard Review 08 GIGABYTE Z270X-UD5 Motherboard Review 08](https://static.tweaktown.com/content/8/0/8064_08_gigabyte-z270x-ud5-motherboard-review.jpg)
The rear IO panel features PS/2 Keyboard/Mouse, two USB 2.0 ports, HDMI, DisplayPort, two Intel NICs, USB 3.1 type-C, USB 3.1 type-A, three USB 3.0 ports, and audio outputs with S/PDIF out.
![GIGABYTE Z270X-UD5 Motherboard Review 09 GIGABYTE Z270X-UD5 Motherboard Review 09](https://static.tweaktown.com/content/8/0/8064_09_gigabyte-z270x-ud5-motherboard-review.jpg)

The PCI-E layout is quite simple. The first and second x16 slots share x16 PCI-E 3.0 from the CPU. They operate at x16/x0 or x8/x8. The last x16 slot gets its x4 PCI-E 3.0 from the PCH and shares the bandwidth with two of the x1 PCI-E slots. The x16 slots are reinforced by a single piece metal shield, and each slot uses a metal lock notch that is soldered to the PCB. The motherboard has a single x4 PCI-E 3.0 M.2 slot located right below the CPU socket.
![GIGABYTE Z270X-UD5 Motherboard Review 11 GIGABYTE Z270X-UD5 Motherboard Review 11](https://static.tweaktown.com/content/8/0/8064_11_gigabyte-z270x-ud5-motherboard-review.jpg)

Four SATA6Gb/s ports are located below the U.2 port. The other two SATA6Gb/s ports are SATA DOM ports, and SATA DOM power is included. I believe you can use the SATA DOM ports as normal SATA as well.
![GIGABYTE Z270X-UD5 Motherboard Review 13 GIGABYTE Z270X-UD5 Motherboard Review 13](https://static.tweaktown.com/content/8/0/8064_13_gigabyte-z270x-ud5-motherboard-review.jpg)

There are two USB 3.0 internal headers, and a USB 2.0 type-C header located right below the 24-pin connector. USB ports like the single USB 2.0 port can be used for a variety of things, but some high-end software have keys that are on USB sticks and must always be plugged in to use the software. The motherboard does have overclocking features such as voltage read points, POST Code display, OC button, ECO button, Clear CMOS button, Reset button, and power button.
![GIGABYTE Z270X-UD5 Motherboard Review 15 GIGABYTE Z270X-UD5 Motherboard Review 15](https://static.tweaktown.com/content/8/0/8064_15_gigabyte-z270x-ud5-motherboard-review.jpg)

The VRM on this motherboard is in an 8+3 phase configuration, the eight CPU phases are doubled up from four by doubling of the components per phase. GIGABYTE is using their Power inductors and 10K FP capacitors. The PWM controller is the Intersil ISL95866 4+3 multiphase R3 PWM controller. The +4 rail has two integrated drivers while the +3 has a single integrated driver. GIGABYTE adds four extra drivers so that they can use all 4+3 phases.
![GIGABYTE Z270X-UD5 Motherboard Review 21 GIGABYTE Z270X-UD5 Motherboard Review 21](https://static.tweaktown.com/content/8/0/8064_21_gigabyte-z270x-ud5-motherboard-review.jpg)

GIGABYTE's ALC1220 implementation relies on the new integrated headphone amplifier for the 120dB SNR output. They also use Nichicon audio capacitors to improve audio quality and divide the audio section of the PCB from the rest of the motherboard. There are six LEDs located in the audio section; they are yellow.

GIGABYTE's UEFI was revamped right before Z270 launch, and the new UEFI offers much better fan control over its predecessor. The GUI fan control is decent and good enough, so you do not need to use GIGABYTE's Windows based software.
The rest of the UEFI is pretty much the same as the rest of GIGABYTE's Z270 lineup. That means you will find solid overclocking options, control over all motherboard features such as ThunderBolt 3 and storage, and decent BIOS layout and organization.

The Z270X-UD5 has very solid performance all around, and it should considering it is designed to be an everyday motherboard with solid stock and overclocked performance. The Z270X-UD5 has multiple strong points, one of those is the synthetic GPU benchmarks.
Some motherboard reviews put a lot of weight into motherboard CPU, memory, and GPU benchmarks, but for me, CPU, memory, and GPU benchmarks on motherboards should be more about finding anomalies, and I do that at standard settings (4.8G in graphs).

The Z270X-UD5's M.2 and U.2 performance were excellent, SATA was great too (sequential write was a bit low), and networking was what I have come to expect from Intel NICs.
Audio RMAA 5.5:
I disable all audio features, set the correct bitrates, and then test the audio with a loopback test.
![GIGABYTE Z270X-UD5 Motherboard Review 90 GIGABYTE Z270X-UD5 Motherboard Review 90](https://static.tweaktown.com/content/8/0/8064_90_gigabyte-z270x-ud5-motherboard-review.png)
Sound Judgment by Ear: Excellent. GIGABYTE's ALC1220 is good enough. There are five ratings for audio: 1. Problems, 2. Okay, 3. Acceptable, 4. Very good, 5. Excellent
Thermal Imaging and Power Consumption
System power is measured at the wall with an AC power meter.

Note on Thermal Images: In the temperature section, we use our Seek thermal imaging camera to capture the surface temperatures of major components on the board. I look at the VRM and then all other things that light up the screen. If there is something to worry about, then I will state it. Otherwise, I will just show the hotter running parts of the board for fun. Unless some component is over 80-90C, then there isn't anything to worry about.
All systems will act differently, so I will look for commonalities, such as how far from the VRM the heat spreads through the PCB and the difference in temperature between the front side and backside of the PCB. Keep in mind, the majority of the heat from the VRM goes into the PCB as it is a giant soldered on copper heat sink. A larger difference in temperature between the back and front of the PCB points towards a more effective heat sink.

The Z270X-UD5's thermal performance is great. The VRM isn't the best I have seen, but it's decent enough to get the job done, and it shouldn't let you down even with a very high overclock on the CPU.
Anything under 60C is great, 60-80C is acceptable, and anything above 80C is a bit worrisome (if at stock).
What's Hot, What's Not & Final Thoughts
Here are key points about the GIGABYTE Z270X-UD5.
What's Hot
ThunderBolt 3.0: The Z270X-UD5 costs $199.99 and at that price point you don't expect to find ThunderBolt 3.0, but alas, the Z270X-UD5 has the fastest consumer connection available. The ThunderBolt 3.0 port also doubles as a USB 3.1 port and supports 36W of output.
Workstation Features: The motherboard has a surprising number of features many would consider workstation-like. It is the first motherboard I have seen in the consumer arena that has a built-in POST speaker, two powered SATA DOM ports, and two COM ports. The vertical USB 2.0 type-A port could also be considered a workstation feature, capable of internally housing a USB key for expensive software.
Overclocking Features: The motherboard also carries a lot of overclocking features, including power, reset, clear CMOS, OC, and ECO buttons. It also offers a single BIOS mode switch, dual BIOS ROMs, voltage read points, and a POST-code display.
No-Nonsense Aesthetic: Some enthusiasts are extremely anti-RGB. They dislike how most motherboards light up and don't want to pay for RGB headers. The Z270X-UD5 has no RGB headers and no RGB LEDs. It's heat sink and PCB design also screams no-nonsense, it's simple and looks whole.
Dual Intel LAN: I didn't expect to find two Intel NICs on this motherboard since it also offers ThunderBolt 3.0, but the Z270X-UD5 has dual Intel NICs and ThunderBolt 3.0.
What's Not
Single M.2 slot: Most motherboards at the $200 price point offer at least two M.2 slots since M.2 is the most popular platform for faster consumer drives. While the Z270X-UD5 only has a single M.2 slot, you do have the ability to add in more through the last PCI-E x16 slot which is wired to the PCH.
Final Thoughts
GIGABYTE's Z270X-UD5 represents a lot more than the continuation of the next UD5 iteration; it represents the continuation of GIGABYTE's entire Ultra Durable lineup.
The addition of more workstation features and high-end connectivity and removal of aesthetic ones such as RGB LEDs helps separate the Ultra Durable lineup from the Aorus gaming lineup.
![GIGABYTE Z270X-UD5 Motherboard Review 104 GIGABYTE Z270X-UD5 Motherboard Review 104](https://static.tweaktown.com/content/8/0/8064_104_gigabyte-z270x-ud5-motherboard-review.jpg)
GIGABYTE is hedging their bets on two segments of the enthusiast market, and the Z270X-UD5 is a perfect incarnation of the split in GIGABYTE's motherboard offerings. Some people want tons of gaming features, they like the gaming NICs and RGB LEDs, and others want a motherboard with workstation-like features but the ability to support high-end gaming as well, and that is what the Z270X-UD5 offers.
If you are in the market for a no-nonsense motherboard, capable of filling many shoes, then give it a look.
