Monitor Kit
status OLED

Status OLED

Status OLED shows various information of the system on a new high resolution OLED screen. Now you can use three buttons to toggle between information of the power on self test, debug codes, the current time, temperatures, frequencies and voltages of various points on the motherboard.

multi thermal sensor

Multi-Thermal Sensor

Multi-Thermal Sensor provides users the temperature of various parts of the motherboard graphically, so that users may precisely keep track and control the temperature of each part of their motherboard when overclocking.


Waterproof by Conformal Coating

Conductive liquids such as water pretty much destroy all kinds of electronics on contact. That’s why ASRock has implemented a special layer of Conformal Coating on our motherboards, which makes the motherboards invulnerable to conductive liquids, corrosion and dust. Users won’t have to worry about spilling liquid nitrogen, liquid helium or even clam chowder over their motherboards while overclocking.



Connect your PC and another device to one monitor and toggle between the primary and secondary screen without replugging the connectors every time.


Home Cloud

This motherboard supports remote wake with the onboard Intel LAN, so you can connect with your PC from anywhere in the world. You will be able to power your PC on or off, and monitor and take control of it remotely with another smartphone, tablet or computer.

5 out of 5 eggsIt's simple: This board is PRETTY COOL!

Pros: Whether you're looking for stability or some rocking overclocking capabilities, this board does not disappoint. Nice BIOS GUI and love the mouse support, it's really easy to configure and navigate. If you're a noob, you'll find it pretty easy to use. If you're a geek like me and want to tweak timings, voltages, etc., then you'll find it easy to customize as well.

Cons: I did have a few show-stoppers when I first received the board:
1. An error message "USB hotplug" displayed at boot, and would not boot into Windows setup. To clear this error, I had to remove all my RAM and all connected SATA drives, then install 1 stick of RAM at a time, allowing the system to finish posting. I repeated until all RAM was installed, then connected my SATA drive. This seemed to work, despite flashing BIOS. I don't know why this caused me issues because this RAM was listed as tested and confirmed by Asus.
2. Windows 7 Ultimate would hang at 'Starting Windows' screen and never boot when the Asus Installation CD was in the drive. Removing the disk allowed Windows to successfully boot. My connected drive was a Samsung BD connected via SATA.

Once I got past these issues, I was willing to shovel that off as a minor annoyance. I am VERY pleased with this board which is why I still gave it 5/5 eggs.

Other Thoughts: I've had troubles with Asus boards the last 6 years (I buy many Asus boards in lieu of a PC building business, 10 or so a year). It seems lately that Asus boards have a 8/10 on reliability. I think Asus needs to adopt some better quality controls, it's really frustrating when you get a DOA board or when you're very experienced and despite everything you've tried, the board really doesn't work at all! However, the tech support at Asus almost always has a trick up their sleeve so you don't need to send it in for repairs. If you can get an English-speaking agent they are pretty helpful (no offense to anyone, really!)

5 out of 5 eggsHappy I Tried It

Pros: Feature-rich with amazing built-in sound, built-in wifi and enough ports for any application. It has a great user-friendly bios that makes tweaking it possible for non-techies.

This board just feels like it is well crafted, it's a beautiful piece of hardware made with superior materials to most mobos I have seen.

I was between this and a nice Asus for a high end gaming / music production rig, really happy with it!

Cons: None so far.

Other Thoughts: I was hesitant to buy from a newer company with mixed customer service reviews, but mine works fine and when I had a question, they responded quickly.

5 out of 5 eggsDoes it all

Pros: This board is great, does it all. You can customize the settings for pretty much everything in the BIOS and/or the ASRock software, which also provides great temperature monitoring abilities.

PCI-E slots were also spaced far enough apart that I had no issues installing 2 very large (double width with 3 fans each) video cards. The built in wireless is great, and the ability to adjust RAM speed is very useful if you want to get some very high-spec memory.

Cons: None.

1 out of 5 eggsNo RAID slow POST

Pros: Bluetooth, 802.11ac, and a host of other specs, nice GUI BIOS.

Cons: I'm a big fan of RAID, so I bought this motherboard to do raid 10 however dispite following the directions to the letter and trying with both a USB 2.0 keyboard in both USB 3.0 & 2.0 slots, and even trying a PS/2 Keyboard, RAID configuration won't open. Furthermore POST, fresh out of the box takes 1-3 MINUTES to finish. that's PRE OS booting. I'm using win 7 pro. Maybe its better of 8 O can't say. I just say if I didn't get a bad batch stay away. emailed their custemer support (NO PHONE EMAIL ONLY) and I'll update this if they get back to me.

Manufacturer Response:

Dear ASRock Customer

We sincerely apologize for any inconvenience this may have caused you.
For the RAID setting, Please visit the installation guide at link ""
Plug keyboard and mouse to USB 2.0 ports (grey).
However, mainboard supports Windows 7, 8, and 8.1.

4 out of 5 eggs

Pros: solid board. easy to put in case. good price.

Cons: This product is easily confused with the Non ac model so make sure the first thing you do upon getting your motherboard is check for the WiFi module. This was my mistake and now I have RMA. other then that i have no compliants seeing i haven't even turned on the board.

5 out of 5 eggsASROCK Formula/AC board top notch!

Pros: High quality Ethernet, wifi AC/BT included, HDMI in, very high quality PCB board and hardware, onboard sound rivals the best dedicated sound cards, stellar 5 year warranty

Cons: None, but a lot of unverified users posting reviews here who I doubt even own this board.

Other Thoughts: First off, you have one user here stating you need to route the wireless antennas outside of the case. That's not true. The antennas bolt to the I/O shield.......then you run the extender outside of the case, or you can replace with a pair of antennas that bolt directly onto the I/O shield if you want.

Second, one user here wrote a review complaining about no wifi/BT........well that's because you have to get the "AC" model. The regular formula board has no wifi AC/BT nor claims to. Glad that gentleman is a stickler for details when he orders up products.......

3rd gentleman is giving himself a 5 star rating on technical knowledge, yet he can't boot up his OS? Really? This board's BIOS is about as straightforward and easy to diagnose as they come. Obviously he didn't read the manual either, which gives a few more details than he let on. ;)

Some people should NOT be allowed to post a review IMO.

This is a fantastic board, be sure to update BIOS to latest 1.6 revision and you will have a rock solid OCing/gaming board that is the best of the best.

4 out of 5 eggsFeature-Rich

Pros: Had enough connectors to last for years. Easy setup and everything worked great out of the box. HD audio was definitely good enough for me. No sound card needed.

Cons: Had issues seating the GPU card. Not sure if it was the board, the GPU, or the case. However, I had to pull it out and reinstall to get it to sit right.

Other Thoughts: Make sure to install the wireless antenna connectors first. Otherwise, you may need to remove large GPU cards to install them. Also, make sure to push out the wireless antenna slots on the backplate first as well (2 of 3) so you won't have to look for small slits of metal in your case/under your newly installed board.

1 out of 5 eggsUEFI/BIOS issues

Pros: A ton of overclocking potential; northbridge has waterblock for custom cooling loop

Cons: UEFI/BIOS will not allow me to boot ANY drives (SDD, HDD, optical, etc) and thus I cannot install an OS! Documentation is poor with no OLED display codes explained; Have not heard back from Asrock tech support and am incredibly disappointed.

Other Thoughts: I am hoping that their tech support department contacts me soon, but the word on the street is that their tech support sucks. I hope they prove me wrong.

Manufacturer Response:

Dear ASRock Customer

We sincerely apologize for any inconvenience this may have caused you.
Please connect the HD drive to (SATA3_0) and optical drive to (SATA3 _ 5) ports.
Check both HDD and optical drives have been detected by mainboard under BIOS, Advanced, Storage configuration.
Set the desire drive to boot at UEFI, Boot, Boot option #1 (please also check Hard Drive BBS priorities).
Also try press F11 repeatedly to bring boot menu once power on, select desired drive to boot.
If you have any technical issues or warranty questions please contact our Tech Support at We can assist you shortly.

Thank you
