4 out of 5 eggsNice Board Bro!

Pros: I have had this board for over a year now. I want to preface this by saying; I PUT THIS BOARD AND THE CPU IN IT THROUGH HELL AND IT STILL WORKS. As of right now I'm running an FX-9370 with this baby. I've used the build that it's a part of right now as a daily driver since mid January 2014. I've Overclocked, Over-volted, Under-volted, and even had my 9370 overclocked to 5.1 Ghz with air-cooling on a 100 degree day in the middle of Georgia. Even through all of that the board is still fully operational and is still in use right now.

Cons: The first few days I had this board running in the build I had 2-3 blue screens. It has blue screened periodically when Idling or under light loads but never when it's under heavy load while I'm gaming or rendering something. I'm pretty positive that it's something to do with my processor and board combination , seeing as the ASRock website doesn't say the CPU is supported on this board. The Northbridge gets pretty hot even if you have good airflow in your case.

Other Thoughts: Pros:
- Can take a beating
-Good daily driver
-Decent overclocker

-Blue Screens sometimes
-Northbridge runs HOT

TL;DR ~ Great board, Good Price, Minor Hiccups, 8/10 Would Recommend

5 out of 5 eggsGreat first build

Pros: Cheap, the UEFI was extremely easy to use and figure out. I recommend this motherboard who's looking to build a cheaper gaming pc for their first build as it has a lot of potential to do some pretty cool stuff with.

Cons: I really don't have any complaints about it.

Other Thoughts: This was for my first build and is amazing for how inexpensive it is.

4 out of 5 eggsGreat motherboard for the price

Pros: 8+2 Power Phase lets me use my FX-8350.
Being able to update the BIOS from the BIOS worked great for me.

Has been running rock solid stable for the past 10 months. No BSOD, no hangs. I've been gaming on this thing pretty hard since I got it, and it's taking it like a champ.

Cons: Most of these are just minor complaints, since I was able to get this board working just fine in the end.

Color Scheme is horrible
Could use a few more SATA Ports
No noticeable difference between the Killer USB port and a standard USB 2.0 with my mouse.
USB 3.0 Header is a little flaky. I'm not sure if it's the ports on my case, but they seem to work when they feel like it.

Audio quality from the built-in sound isn't the greatest. Took quite a bit of tweaking to get it to sound right in games.

I only ran into a few issues when first setting up this motherboard. Mainly the Atheros Killer NIC. Drivers from ASRock just wouldn't work at all. Obtaining them directly from Atheros solved the issue.

Did not recognize my RAM at first. Had to boot into BIOS with one stick 4GB stick installed, and manually configure it. After that it recognized all 16GB of RAM.

Other Thoughts: I have been using this motherboard the past 10 months without any issues. It's true that the VRMs and the North Bridge do run rather hot, but this has not been an issue for me. I have this installed in a Cooler Master HAF 932 Advanced full tower with a massive amount of airflow.

I haven't really bothered to try any overclocking as I don't really need to. The FX-8350 provides more than enough at stock speeds, and never overheats with my Corsair H60 liquid cooler.

Overall, this is a pretty decent board with a lot of features. I would recommend this to anyone not really interested in overclocking since it does run rather hot at stock settings.

4 out of 5 eggs

Pros: Have M2. SATA port. Full x16 for Crossfire and has molex power for high power GPUs. Software for NIC and the NIC is supposed to be good for gaming. 8+2 power phase.

I did not run into any software glitches and everything installed fine. No BSOD or problems.

Cons: Runs hot. Way too hot. I saw a review of this after I already made the purchase, and the review was that the board runs hot and not energy efficient. I thought all AMD CPUs run hot but this is more unusual.

My 8320 running at stock the VRM already idles at 45C. CPU idles around low 30s. Full load and it shoots up to mid-50s. From what I read 8320 temp needs to be under 60s so no chance of any OC.

Other Thoughts: For the price that I paid it was okay, and for the purpose that I want it is also okay. If you want high end and OC, you need to go with ASUS Sabertooth or Crosshair. If you grab this expect no OC. For my Antec case I have 2 intake fans, 2 internal fans blowing on the south bridge, 2 top exhaust, and 1 rear exhaust. Still hot.

My build -
FX 8320
ASRock Fatal1ty 990FX Killer AM3+
Thermaltake Frio
EVGA GTX 660 x2 in SLI
16GB Kingston DDR3
ADATA Premier Pro SP600
SilverStone Decathlon 800W PSU
Lite-on DVD drive
Antec P280 case

5 out of 5 eggsgreat motherboard for the money

Pros: Tthis is a great board with alot of options for the buck im a previous owner of a asus crosshair motherboard and had problems with 2 rma boards decided i would buy this board since its 1 of the newest amd board for a 8 core cpu this is by far a better board ive reached better clocks and more stable clocks with this board runs cooler and has a nice lay out to also having the m.2 option available is also nice if you are looking for a good board and a asus or gigabyte fan like a was and not sure about taking the leap for this board go for it you wont regret it this thing is must and a best buy. plsu as it appears this might be the only amd board that supports pcie 3.0 as it seems it miss advertised her rather than the site which is a big plus

Cons: None really this is a amazing board keep up the good work asrock

Other Thoughts: will reply back in a few months

1 out of 5 eggsHorrible.

Pros: Looks nice, great features, very nice audio quality (mostly...)

Cons: This is where the real review is going to be.

I have had nothing but problems with this board.
At first I wasnt sure what the issue was. Took a lot of time to pinpoint what the issue was.
Doing anything from simple tasks to light gaming would give me brief lags. Just total freezes, about a second long.
So we tore the pc back down and checked everything. Turned all features off and did it again. BSOD. Failure to start. Over and over. Mind you this is at stock settings (8320)
So I swapped the cpu with another 8320. Same exact thing, running the exact same temps. Same clocks, same cooler (h100i).

So now what... Lets contact them. HA. It has been 3 weeks since I first contacted them. I have yet to get a response or a call back.

Problem turned out to be the VRMs and CPU socket overheating horribly. Right now (board is still in till the new one gets here. Not getting this one again.) while writing this review the socket temps / vrms are sitting at 49c. CPU at 22c. Horrible.
Should also add that I have to have a fan blowing directly on the vrms just to even keep them that cool. It was the fan off the stock heatsink for the 8320.... and it is always on, full power and plugged into the CPU fan header.... pathetic.
I have had to downclock the CPU just to even use the stupid thing. 3.2 ghz. Any higher and its glowing.

Other issue...
usb3.0 header dont work. At all.

Overall, I would never recommend this board to anyone. For any reason.

Other Thoughts: Get something else. UD3 is a solid board priced about the same, few $ cheaper. And it is a known awesome board.

1 out of 5 eggsTime of Death 3/09/14

Pros: Red an black

Cons: The northbridge and Vrm always ran to hot. The cpu throttling even at an low overclock 8320 at 4.200 would throttle. Random BSOD with lead me to believe my memory was bad.

Other Thoughts: It had a seizure then when into a coma and has never came back. Time to try other brand.

4 out of 5 eggsGreat but not perfect

Pros: lets start of with the good shall we,
handles upto 2450Mhz ram: if you can find them, but 2400mhz does the job, but if you are using that speed only use the black slots, apparently, i haven't bought a 2nd set because 16GB (2x8) 2400mhz is more than enough,

M.2: you can use the sata ones but pci-e is better but more pricey

PCI-e:16x 16x 4x with a power stabilization buckle down the bottom (im only using 1 card right now so its not needed but good to have.

5x sata6gb/s ports, more than enough

UEFI: so easy to use compared to a Gigabyte board i have used before

Cons: now for the bad,

the VRM's/Power control on this board is trash, but its meant to be a gaming board not an overclocking board :( even the simplest gamer wants to toy around a little. it says on many sites that not suitable for FX-9 series, that alos covers oc'd FX8 series and also depending on how hard you push your FX-6, but that said i have an FX-9370 with cpu only OLC water, been thinking of getting a VRM and NB block to suit, sadly though that is a gamble because no one makes them for this particular board, so the aftermarket support for this board is bad too.

and now for my biggest hate of this board, RED AND BLACK, i am sick to death of this colour scheme on the best boards, but if you want great features you have to sacrifice some where.

now i see people have complained about the sata port connectors, myself i love these cause i have a monster case and it makes the cords look neater, but i can see where it would cause a pain for those who like small cases!

the last issue is with custom water cooling, i have seen many video installs of the waterblock i have (XSPC Raystorm) on different boards and they all fit nicely and could even use tension nuts on the screws, this board how ever seems to be a little higher on the cpu block, i could just get enough thread in to screw it down slightly, i had no room to use the tension screws, currently looking for some riser screws so i can fit it properly.

Other Thoughts: it is a great motherboard, it could be better, the heatsinks look too much like solid blocks rather than a heatsink for cooling, more fins next time guys, and please better VRM's and power control and lastly make sure people are able to add on stuff easily like Water Blocks and water blocks and more water Blocks.

5 out of 5 eggsSo far so good

Pros: When I received the motherboard, I noticed when opening the box the quality of the motherboard. The components appeared to be assembled accurately, none of the components seemed to be bent or damaged. I give a plus to quality control. I installed the motherboard about a week and a half from the time I purchased this board. After installing the board and all the other components (Memory, Processor, Power supply, HDD, & Video card) when I powered-up the computer for the first time it fired right up no problems what so ever. At this time the computer has been running strong and no glitches as of yet.

Cons: Some of the components on the board may get in the way of installing HDDs

Other Thoughts: Like the board, I would buy it again. This is my second ASRock board and I have not had any problems with either of them as of yet. My other ASRock MB is a Z77 Formula OC and I have had it for about 3 years its solid and has never given me any problems.
