High Density Glass Fabric PCB

What you’ve never understood about your computer is that it is scared to death of water, H2O, humidity or whatever you’d like to name it. And even though you do not see the water, actually there may be lots of excessive moist in the air killing your motherboard silently and slowly. No, your motherboard doesn’t melt when in contact with water like the wicked witch of the west, but it dies of short circuit. Luckily, ASRock has a new High Density Glass Fabric PCB design that reduces the gaps between the PCB layers to protect the motherboard against electrical shorts caused by humidity.

10 Power Phase Design

The power phase design offers smooth power delivery to the CPU, unmatched overclocking capabilities, lower temperature for advanced gamers, and reinforced system stability for taking on all sorts of arduous computing tasks.

ELNA Audio Caps

Who says high quality audio is only available on high-end motherboards? ASRock applied ELNA audio capacitors on mainstream and entry-level motherboards! Compared with traditional solid caps, the leakage current of ELNA audio caps is merely 3uA. This is the key to reduce noise level significantly and satisfy even the pickiest audiophiles.

Good lucking, poor performing

Pros: Looks great
Easy to install
Great price for a z170 board
BIOS runs well and has many options

Cons: Board failed within 2 months
Flimsy construction quality; but on par with price
Terrible customer service
RMA process is basically useless, received not one...but TWO boards with bent CPU pins from them in a row, gave up after that.

Other Thoughts: I would not recommend this product. Although I finally twisted their arm enough to get an RMA out of them, the board was shipped with bent CPU pins. Entire process was a nightmare.

Reliable motherboard with an easy OC interface

Pros: - Multiple USB 3.0 and 2.0 ports

- Overclocking is easy to customize and use

Cons: - I've noticed that, in time, there is a fair amount of static and feedback when using any of the auxiliary or 3.5mm ports

Other Thoughts: I've owned this motherboard for a little over a year and a half now.

Was doing great

Pros: -80 dollar mobo that can handle skylake cpus
-easy installation for me
-skylake cpu worked out of the box no bios update needed, I see a lot of reviews saying they had to do an update. I guess I was lucky?

Cons: -4 months in 2 ram slots stopped working so I can either run 4gb ram in dual channel or 8gb in single channel

Other Thoughts: -Sent an rma request, currently waiting to hear back so I can send it in. Not impressed so far, been a long time asus buyer and if this falls through i will be going back to Asus. I've read a lot of reviews from varying sites saying that others have tried to RMA and the customer confirmed there was no bent pins, but Asrocks customer service reported back to them saying there was bent pins. That makes me worry about the companies integrity. I've built a lot of custom computers, several for myself over the years and several for others and I've never had to do an RMA before. I've also personally never had a DOA product, so I guess i've been lucky up til now.

Dear Corey,

We sincerely apologize for any inconvenience this may have caused you. ASRock mainboards are fully tested to assure the quality.
The CPU socket has been covered with protection cap to avoid damage the pins.
CPU contact pins on the mainboard are fragile and need to be careful to avoid physical damage and affect the limited warranty.
In addition, bent pins could cause malfunction to memory slots due to memory controller in the CPU is not fully contact with the pins.
For more information about CPU installation guide, please visit at link " http://www.asrock.com/Support/QA/TSDQA-103.pdf ".
If you have any technical or warranty inquiry, please contact our Tech Support at http://www.ASRock.com/Support/tsd.asp

Flimsy, lacking in ports; Great value for a Z170 board

Pros: The price on this for a Z170 chipset is hard to beat
Decent selection of affordable RAM on the QVL
No bulky heat sinks or flashy junk on the board

Cons: No LEDs for diagnosing hardware errors
No USB 2.0 ports, only a single PS/2 port which didn't seem to work (this made installing Windows 7 very challenging, no problems for Windows 8 or 10)
The UEFI was 4 versions old out of the box (fortunately flashing it was very easy with the built-in tools)
Relatively low number of SATA ports (6), all upward-facing and clustered pretty close to each other

Other Thoughts: My unit was bent out of the box. While I imagine that's an outlier, in general this board felt as cheap as it was. I was afraid to use force when clipping hardware in to the DIMMs and PCI slots.

I personally went with a 6th gen chip, but I've heard that the 7th gen i5s and i7s don't work out of the box on this board. Other users have reported that they do work after a UEFI update.

I have the Zalman radial copper heat sink (you know the one) on top of my CPU and it fit on this board without any fuss.
