Pros: No problems setting up its profiles.
LEDs aren't in your face.
Plenty of nice features on it.

Cons: Did not clearly state that the motherboard would not work with 2nd generation Ryzens without prior bios update. This caused me to run all over town to find a first generation Ryzen processor to install the update on before I could even use it with the one I initially wanted.

Other Thoughts: Honestly, great motherboard, but that BIOs thing was such a huge waste of my time, and it is all because I didn't do deep enough research on this motherboard, and the fact the manufactures/suppliers didn't mention anything about it.

Pros: Pros: The motherboard comes with ten SATA ports, two M.2 sockets, two USB 3.1 ports, ten USB 3.0 ports, and 4 USB 2.0 ports. It is loaded. All of the SATA ports seem to be functioning properly along with the USB 2.0 and 3.0 ports. I have yet to test the USB 3.1 ports or the M.2 sockets. I was surprised to find the onboard sound system is quite good. It uses a Creative Sound Blaster Cinema 3 codec. I have always preferred to use Creative Sound Blaster audio cards in the past. They just sounded better. The UEFI BIOS is quite good. It automatically set the proper speed and timing for my RAM modules. It is self explanatory and very easy to understand. Much better than the old Intel BIOS I have used in the past. Trust me. I have put together eight computers for myself and family members using Intel motherboards. I know of what I speak. The build quality of the board is excellent and there were no damaged of bent parts. Oh, I am not big on wild color schemes… But the black and red PCB, along with the RGB lighting, is very nice to look at. I have never owned a motherboard that was not green in color. One nice feature I have noticed is the location of the CMOS battery. They didn’t try to hide it underneath the graphics card. That makes it much easier to replace when it dies. You don’t have to remove the video card. Well, as long as the graphics card is only a two slot model.

The software that came with the board is useful if not flashy. I have found the F-Stream Control Utility, X-Fast LAN Utility, Sapphire TriXX Tweak Utility, and the ASRock Live Update & APP Shop to be the most useful. Oh, one other nice touch. They also provided a written manual. An honest-to-goodness 82 page written manual. I have been used to dealing with nothing more than a Quick Setup Guide when putting together an Intel motherboard. A manual is much better.

Cons: Cons: There are only two I am able to think of. The loose Standoff for the 20GB per second M.2 socket. Unlike the Standoff for the 32GB per second Ultra M.2 socket, which is attached to the motherboard, I found it loose inside the anti-static bag with the motherboard. I noticed a few other people had written reviews mentioning this prior to my purchasing the motherboard. I am very grateful to them for the heads-up warning. The only other thing I can think of that concerns me is a retention mechanism on the graphics card side of the DIMM slots. I understand this arrangement makes it easier to to replace RAM modules without having to remove the video card. Still, I would feel a lot more comfortable with them. Oh, yeah. One more thing. The ASRock Live Update & APP Shop seems to conflict with a few applications such as Skype, Windows Update, and the Steam Engine. They appear to have trouble communicating properly with host severs when the ASRock Live Update & APP Shop is active.

Other Thoughts: I needed something new. Microsoft was going to end support for Windows 7 and I had never tried to update my old computer’s operating system. It was a pretty nice system when I first built it. It had an Intel Q9650 Quad Core Processor and an Intel DP45SG Motherboard with 8GBs of RAM. Ancient, right? I started looking at processors and motherboards with the thought of building another Intel based machine. However, I found the prices a little steep. I decided to look at AMD processors and motherboards. Lord, was I surprised at what found. This little beauty was one of the best equipped and best looking motherboards I found online.

I have had the motherboard for only 5 months. I have made no attempt to over-clock anything yet. It has given me no problems thus far. Would I recommend this motherboard? Yes, yes I would. It is a great motherboard for the price.

Pros: -mounting screw holes easier to deal with and free of other stuff around the holes.
-onboard power/reset switches.

Cons: -i still hate, 1 sided RAM slot locks. even though graphics card would be in way. the 1 sided ram locks i do not trust.
-10 sata ports all tight and together, half directly under graphics card. 1 sata port with a sata cable with a "lock" on it, needs graphics card removal to remove sata cable.

Other Thoughts: -no internal buzzer/speaker came with motherboard.

Pros: 10 sata ports was a big win.
M2 slot.
64G on the MB
2x ethernet

Fedora 29 didn't have any installation issues.

Turning on Virtualization was easy ONCE YOU REALIZE THERE ARE TWO OPTIONS that look similar --
yup, it was the second one that actually does it (sorry - can't look at it right now for obvious reasons
to tell you the exact location).

Cons: The M2 slot's (nearest the CPU) standoff screw was non-intuitive (that is, it wasn't already installed in
the MB). I forget exactly where it was in the packaging. Don't forget this screw if you use an M2 stick!

Didn't need 3 video card slots. It's a trend, I guess but hopefully with mining going by the wayside,
we'll get back to a sane expansion slot configuration among manufacturers.

Other Thoughts: This is my 1st ASRock. I used to use ASUS, but their linux support has gone down hill.

I've built about a dozen systems over the years, and they get crazier and crazier over time.
Who would have though programmable LEDs on the mother board would be a thing! Kids...

It's still in the burn-in stage of a couple of days running, but initial test peg it about 2x (stock setup
w/Ryzen 1700) over my AMD FX-8350 (stock setup as well) with programs like ffmpeg.

Pros: Simple bios, easy to get to grips with and update/tweak. This is my first high end board and tweaking everything has been super simple. Updating to run my ryzen 2700x has been hassle free and quick. I really liked the 2 m.2 slots, I use one for OS and high demand titles and the slightly slower one for other games. With B die RAM the board just flies. I haven’t used most of the fan ports as I use a controller but it’s nice to have them along with the debug screen and power/reset buttons. These came in handy (detailed in cons) but I have to add customer support from both newegg and ASrock has been superb. The European distributor helped me troubleshoot and then directed me to ASrock US when troubleshooting didn’t work. Big thanks to Bobo at newegg for telling me how to do manufacturer RMA. I sent the board the Thursday before Christmas, it arrived in California 30 hours later, and I had a replacement in under 2 weeks. Respectable for the busiest period of the year.

Cons: The only issue to report was faulty pcie slots on my first board, I didn’t discover this initially as I built up my pc parts over a year. Both slots suffered intermittent connection to my gpu (2080) despite the card being aligned perfectly. A little disappointing, but having read reviews of other brands boards I understand these things happen from time to time. The only painful thing was covering the shipping and having it sent to an American friend so that the RMA could be honoured. But everyone was helpful and patient, and you can’t ask for more than that.

Would also be nice if it came in other colour ways apart from black and red.

Other Thoughts: A good solid board which handles current ryzen well. Getting cheaper all the time so worth considering, my alternate was a tai chi but I don’t regret getting this

Pros: - Runs Great, no real performance issues.

Cons: - Ram is set lower than usual and interferes when you try to run crossfire. Bought a second Vega 64 and didn't fit so now I need a new motherboard that works perfectly fine.

Pros: Looks like a great product with all the features, including 10 SATA ports.

Cons: NewEgg shipped a board with a 1st generation x370 chipset/BIOS which will not work with the current (recommended) Ryzen CPU. I need a board with the upgraded BIOS. Since the board will not boot due to the incompatibility, I have no way to flash the BIOS and had to return it.

Pros: Looks nice

Cons: Does not work and the RMA in Canada can take up to SIX WEEKS.
When I emailed the ASRock Canada they told me to be patient!!
I do not want to be patient I want a mobo that I paid $400 for in my PC.
