A strong point of this board is all the USB headers. 3 USB 2.0, 2 USB 3.1 type A, and 1 USB 3.1 type C. Currently, very few cases support the type C USB header but that will change just like it did with USB 3.0.
All these headers mean you can add an additional front panel USB adapter that fits in a 5.25 external slot and have 2 more USB 2.0 and 2 more USB 3.0 front panel ports and still have 4 additional USB 2.0 back panel ports.
M.2 cannibilizes SATA ports. M.2_1 blocks SATA 0 and 1, and M.2_2 blocks SATA 3 and 4. This is in the manual and as specified for the chipset but worth noting. So the 2 additional Asmedia SATA ports are appreciated.
I did have an issue mounting a Noctua NH-D15 SSO2 on this board because of the plastic LED shrouding over the back I/O panel but there are 4 small screws and a plug that allow the shrouding to be removed and tossed.
The Noctua is a monster but just fits on the board clearing medium profile memory but only in one orientation: fans pointing to the back of the case.
At first the optical drive barely functioned but after upgrading the BIOS from version 1.0 to 3.0 which had SATA compatibility fixes that problem went away. So update your BIOS immediately.
There are only 3 case fan headers so you'll have to use splitters to fully equip a case with fans.
I built this system in a pretty tight case due to project constraints so getting the 12 volt power connection on while lowering the mobo was entertaining.

1. Load bios by spamming F2 or DEL key at post.
2. Under OC Tweaker tab, please load XMP profile for your memory module.
3. Adjust the BCLK Frequency to default value "100".
4. Adjust the DRAM frequency to "2933" or "3066" manually.
5. Save the setting and exit.
Also it should come with the latest bios update but if it doesn't google this mobo support page and it comes with a handy download of the latest bios, all you do is download, run it and it will reboot and update your bios. Make sure you download the one that does the work for you not the other one that makes you install it manually via usb drive or some bs
Always check to see what bios version you have. You may be on the latest one and not need updating. I was on the latest version and downloaded the updater anyways and it just hanged on the bios update screen for a few minutes. So obviously don't be dumb like me and update when you're already on the latest. For future buyers you will most likely need to update as they will likely not come with the latest bios.
AsRock play stupid to this and when you talk to their tech support department they will tell you to email the issues (including links from their own forums and other forums and sites around the internet) to their "Head Office" who will then send the problems back to the same guy you are talking with.
When I suggested the absurdity of this, he just kinda laughed.
They must have RMA'd hundreds of boards as this exact issue has been going on since the z270 kabylake boards and people are still trying to resolve the issue. I also had the same issues with my z270 board and hoped the z370 boards would have resolved the issues.
AsRock will tell you that they don't have anything to do with the Realtek drivers, they get them from Realtek and test them in their system and then release them.
Realtek won't even talk to you and tell you to speak with your motherboard manufacturer.
Basically a bunch of companies happy to take your money but unwilling to accept responsibility for issues.
The Win 10 Microsoft HD Audio drivers are about as good as you can expect to get with this problem, and some days you may not notice much at all, then others you will hear sound 'pops' and 'crackles' quite a lot.
At least Asus have actually acknowledged on their forums that this is a known issue and they think it has something to do with Nvidia drivers and Win 10, but they are helpless to resolve it.
The only real solution is to buy an actual sound card - pretty sad, but you will waste days trying to fix something that cannot be fixed and these companies will just 'spin the wheels' until people move on and buy new systems.
It's downright fraud in my opinion.

So if you have issues after activating an XMP profile for your memory - try lowering those voltages, or go back to a stable bios version. Hope ASRock will sort that in a future revision of the same.
This problem is my reason for 4 stars for the board. Other than that everything is working perfectly fine!
-VRM is good. Good for overclocking.
-Well packaged, board arrives surrounded in foam unlike many other manufacturers.
-Board feels stiff and thick, not easily bent.
-RAM slots pins are gold plated. A feature which is non existent on Asus or Gigabyte boards at this price.
-12K Nichicon capacitors unlike Gigabytes 10K caps on boards more expensive than this.
-It looks very elegant when installed.
-Best value for money on the market at time of posting. Asrock feels like a company focused on substance rather than fancy dragon graphics and rgb.
-PCIe slot armor is fake, its just a metal cover which is not anchored into the PCB meaning it dose not add to shear or tensile strength of the slot unlike on Asus or Gigabyte motherboards.
-The clearance between graphics card and SATA 3 ports when gpu is installed is almost non existent. The graphics card touches the SATA ports when board is horizontal. This is evident on many non Asrock boards too.
-The error beep codes I recieved were not accurate. I had faulty RAM only, but beep code was 5 beeps which is for CPU error.
-The RAM slots have single sided latch which makes inserting RAM not as smooth as on Gigabyte boards which have double latch and are armored.
Overall an excellent board. Works perfectly. You will have no regrets.
FANS: go in the BIOS, advance mode, HW monitor, scroll down and run Fan Tuning. It is very important to have proper % of rotation and it is useful to stop all the fans rotate at maximum speed when you turn the PC on (that otherwise happens REGARDLESS of the speed you set).
I've changes the mobo but reused the system disk, and I had problems with the x-server despite I've swap M/B with no proprietary drivers in use. The system was using the nouveau standard drivers with an Nvidia.
Solution: sudo remove xserver-xorg-video-intel
RGB leds from the BIOS (nice for Linux).
All OK out of the box with Kernel 4.15 (I've also update the BIOS to 1.18).
I have nothing bad to say about this one easy bios. Easy setup (if you have a cd rom). I supose if i had a niggle it would be the plastic protection patrudes and can be tight fit if putting water cooling fan at top of atx case. But got arround this by putting water cooling in first the set the board (but this could be down to my case not the board.
