The extra large massive aluminum alloy heatsinks dramatically take away heat and cool down MOSFETs, chipsets.


The next generation NexFET MOSFETs provide lower Rds(on) 2.9mΩ, delivering higher efficiency and lower temperature.


Pure black PCB surface. The new Sapphire Black PCB shows rock-solid quality and gives the Sapphire Black PCB motherboard a more mysterious look.


Specially designed for memory power delivery, the new-gen alloy chokes feature a highly magnetic and heat resistant design, thus delivering more stable and reliable power to the motherboard


Nichicon's supreme 12K platinum capacitors! The industry's longest lifespan – 12,000 hours.*
*Tested under industry standard 221°F (105°C) ambient temperature.


Combining with two silicon dies into one MOSFET, Ultra Dual-N MOSFET provides larger die area and lower Rds(on), so the power supply for the CPU Vcore is more efficient.


Compared to traditional chokes, ASRock's new-gen premium power chokes effectively increase saturation current up to three times, providing enhanced and improved Vcore voltage to the motherboard.

Designed with a 12 Power Phase Design, this motherboard features sturdy components and completely smooth power delivery to the CPU. Plus, it offers unmatched overclocking capabilities and enhanced performance with the lowest temperature for advanced gamers as well.
Dual Gigabit LAN – This motherboard provides two Gigabit LAN ports, Intel® I218V & Qualcomm® Atheros® AR8171.
This motherboard supports DDR4 ECC and RDIMM (Registered DIMM) memory modules which deliver server-grade performance and durability for high-powered computing systems.
By adopting digital Pulse-width modulation (PWM), ASRock motherboards can provide CPU Vcore voltage more efficient and smoothly.
The onboard M.2 socket is a new interface for connecting Next Generation Form Factor (NGFF) SSDs or other devices. ASRock is the best in the world at implementing PCIe Gen3 x4 M.2 socket on motherboards. The ultimate Ultra M.2 interface pushes the speed up to 32Gbps which is 6X faster compared to other M.2 Gen2 x1 solutions that are limited to 5Gbps. In addition to support PCIe Gen3 x4 M.2 modules, the Ultra M.2 also supports SATA3 6Gbps M.2 modules.
Purity Sound™ 2 includes 7.1-channel HD audio with Realtek ALC1150 audio codec, 115dB SNR DAC with Differential Amplifier, TI® NE5532 Premium Headset Amplifier, cap less Direct Drive technology, EMI shielding cover, PCB isolate shielding and DTS Connect. As Nichicon audio capacitors are what every audiophile has been longing for on a PC, ASRock applied these high quality capacitors for Purity Sound™ 2.
There's a dedicated 4-pin HDD Saver Connector placed near the SATA ports. By connecting it to the HDDs, you can shut down or turn on the HDDs via software when needed. HDD Saver Technology secures more privacy, saves more energy, and extends HDD life.
Some sensitive digital components on the motherboard are vulnerable to power surges, the excessive current may cause your system to malfunction immediately. ASRock Full Spike Protection includes various technologies to prevent your motherboard's components (USB, LAN, MOSFETs) from being damaged by these unexpected voltage spikes.
We provide various apps and support software for users to download. You can easily optimize your system and keep your motherboard up to date with ASRock APP Shop.

Great Board 8/5/2016 1:24:06 PM

Pros: I won't rehash everything that's been said about this board in the other reviews on here, it's great, the same board as the "Fatal1ty" , the Killer NIC won't really do you any good.

The main point I wanted to make was to let any prospective buyers know that yes, this board can indeed produce good overclocking results. I'm not sure if the other reviewers got unlucky with their CPUs or just were not experienced, but I've had a 5960X in this board up to 4.5 stable, and currently have my 5820k clocked at 4.6ghz at 1.26v and it never reaches past 75C with my H110i. Pretty solid OCs if you ask me. Also have my RAM overclocked to 3100mhz. So if you're on the fence like I was back when I purchased it, just know that it will likely indeed provide adequate overclocking.

Cons: I agree with others that the PCIe setup is poorly thought out, but it doesn't affect me as I highly prefer a single card setup in any case.

Overall Review: I've had this board for around six months now, and it's been a great board so far. Still getting BIOS updates, and it also has been updated to support the new Broadwell-E chips.

Pros: Great value for the price. Was a perfect choice for my mATX build

Cons: DIMM slot DDR4_C1 is bad. I put a known good DIMM in the slot and it posts with a b7 code. Remove a DIMM from the slot and it boots just fine. Upgraded the firmware on the motherboard and tried again. Same post code.

Overall Review: I've never had a problem with ASRock motherboards before. This is the first one I received that was defective. Returning for replacement.

My 2nd review on here after 8 months of ownership. 7/15/2015 8:06:30 PM

Pros: I'm not sure why so many people think that this is a bad motherboard. This board is the exact same as the red "Fatal1ty" board. Anyone that doesn't believe that it is, is more than welcome to peel the black piece of tape that is covering the fatality logo.

The red color version of this board comes with a heatpipe extension of the VRM heatsinks. It also has power/reset switches soldered onto the PCB where the blue one doesn't.

The Atheros QCA8171 that the blue board has, is the exact same chipset as the "Killer E2200". The only difference is the QCA8171 has a PCI devid of 1969:10A1, where as the Killer's is 1969:E091. All of the "Killer" features of the E2200 are on the driver/software level. If you do your research, you'll find that some users prefer to use the QCA8171 drivers instead of the "Killer" drivers on their red board.

I have had my i7-5820K clocked at 4.4 @ 1.35v since November. Never had any issues. And for those that aren't familiar with ASRock boards, they're great.

Cons: The PCIe slot layout is stupid. The first two PCIe slots are x16/x16 (if you have a 40 lane CPU (or it's x16/x8 if you're using a 28 lane i7-5820K like me). Yet the bottom slot is only PCIe 2.0 x4.

I don't care about the PCIe 3.0 x4 M.2 type3 slot. Those are great if you're using one of the VERY FEW SSDs on the market that support this. I want to be able to use two (water cooled, single slot) GPUs at x16 in the top slots. And a dedicated hardware RAID controller for my small SSD array.

Why ASRock didn't make the bottom slot PCIe 3.0 x8, or even 3.0 x4 if the m.2 type3 ssd slot is in use. Or even let the bottom slot run at PCIe 3.0 x4 with a 28 lane CPU. Because as of right now, I have 4 extra PCIe lanes that are not utilized, while the limited PCIe 2.0 x4 is preventing my SSD array from hitting 2GB/s read/write haha.

Overall Review: Overall I'd give this board a 4/5 stars. But I am deliberately giving it a 5 star review to balance out all the negative reviews from reviewers that do not know what they're talking about.

I am running this board in a μATX case, with the CPU and both GPUs watercooled on my custom loop. I ran BOINC projects 24/7 for 5 months straight that kept both of my GPUs, and my CPU at 100%. My Watt meter was read ~850w. Never crashed once.

Idiot Proof 7/14/2015 5:25:59 AM

Pros: You really can't break this thing because it runs CPU speed fluxtuating up and down but keeps up well with internet and works on demand. Runs 10-13 degrees cooler than a DDR3 and feel good and quick enough. Intel burn test gives 135-140 grops (cpu 5820K0 where DDR gave only 1-5-110 on 4820K. definatly use crucial 8gb double sided ram, I did not care for the 4 x 4gb=16 single sided setup.

Cons: Does run stable, don't ask it too but you can coax it up into the 3.0GHz plus range with bios settings.

Overall Review: They really should come right out and tell you this board is not a stability based motherboard,and that the choke is meant for the purpose of varying the cpu speed safely as it does.

This board does not overclock. 1/20/2015 12:24:09 PM

Pros: - One of the cheapest mATX x99 boards
- One of 3 mATX boards that will fit a Noctua NH-D14 and not block the first PCI-Express slot.

Cons: - Cannot overclock at all. Most people are easily able to hit 4.2-4.5 with i7-5930k processors, I cannot even get this build to do 40x multiplier for more than 10 minutes with a stress test. I've looked at multiple guides and have tried the ASRock A-Tuning presets, but I've had 0 success. It might be just a really bad processor, but I have a feeling it might not be. If you are going to advise a board for overclocking, it better work.
