Is a good motherboard. 9/22/2018 3:13:54 AM

Pros: - AMD Ryzen
- They consistently updated the Bios. When I updated recently it improved my video card Cinebench 15 test results by 33%. Don't know why but it did. Games still play about the same though. **shrug**
- Once updated UEFI/BIOS made it easy to overclock.
- Plenty of USB and SATA connections
- pretty

Cons: - No option in UEFI/BIOS for a startup menu. For dual booting.
- UEFI/BIOS probably should have been closer to 4.8 when first released.

Overall Review: - UEFI/BIOS seemed complicated to me compared to ASUS boards. For overclockers/enthusiasts this might be an advantage. Took one star for that.

Decent MB for Ryzen 1700. 2/27/2018 12:01:14 PM

Pros: Booted up on first try.
R7 1700, Wraith Spire RGB Cooler, 32GB (16x2) Gskill FlareX 2400C15, Intel 600P 512GB PCIe x4 M.2 SSD, Mushkin 1TB SATA3 SSD,
Sapphire Radeon RX 580 Nitro+, and LG 16X BD-R BDXL burner in a Cooler Master N400 case with Rosewill Quark 750W Fully Modular 80 Platinum PS.
R7 1700 runs all core 3.2GHz default
RGB lighting works on MB, fan, GPU, KB and mouse.
HD audio is fine both on headphone jack and back panel jack to Klipsch THX 2.1 175W speakers.
Working for 11 months, first with R9 290X, then with RX580.

Cons: Should have a button for CMOS clear like on my old Gigabyte AM3+ MB.
When attempting to overclock memory, continual rebooting. Had to reset CMOS. Took 3 attempts to clear CMOS to get it to reliably reboot in default settings. Appears to retrain memory at stock 2400 settings. quite a few times. Only got it to work by unplugging PS and then attempting boot.
Impossible to extract 580 GPU without removing MB as too close under card to get at disengage lever.
Rear chassis fan header too far away. Should be one in upper back (left) of MB.
Should have module like Gigabyte for connecting Front Panel switches/LEDs to MB (plug front panel headers into module away from case and then plug module into MB).
EOLed after two months.

Overall Review: For those who use WiFi in M.2 E slot, 2 antenna plugs are at top (left) on MB rear panel.
Haven't tried a 580/480 CFX or mGPU setup as few games support same. Thought about it when I started build, got a XFX RS 480 for $220 3/14/2017 and the 580 Nitro+ for $240 on 10/14/2017 Shell Shocker deal.
Don't need it for LG 27"1080p 8bit IPS monitor (580 nitro+ does 90+FPS in ulltra on most games), but do for Acer ETO 43" ET430K 4k 10bit IPS HDR monitor (580 does 25-45FPS on very high no AF (not needed unless you are under 20" from this monitor with 20/20 vision)).

Wouldn't buy again 2/21/2018 8:10:50 AM

Pros: AM4 platform
looks great

Cons: pretty short list of fully supported memory
very few bios updates made available
couldnt overclock a 1600 beyond 3.7 achieved 4.0 on asus strix board

Overall Review: If your looking for a low end plug and play solution this should work for you. If you want to overclock and tinker stick to asus and gigabyte.

Good for a casual user 12/13/2017 11:09:09 PM

Pros: -Initial setup was fairly painless
-If you give it what it wants it will post reliably (more about this later)
-Good vrm
-looks pretty cool imo
-was easy to oc my 1700 to 4.00, could probably go higher, but memory is a bigger priority

Cons: -Memory support is awful
-UEFI is a little weird, and likes to reset stuff randomly
-If you so much as think about oc your memory it will throw a tantrum and fail to post, I get the good ole f9 code plenty
-changing settings in general is a pretty poor experience with this board, it doesn't do what I tell it to do

Overall Review: If you don't plan to over clock it will work fine, or if you want to oc your cpu and are ok with slow memory, this will do the job. Asrock knows this board has memory issues, it's a real shame they didn't just come clean and admit it and try to help those that bought it, as is, I will not be going with an asrock again, the taichi looks to be much better, but I don't want to risk it, I'll just pay out for the hero VI and get a board that has a useable uefi. The thing that makes this so egregious is how dependent ryzen is on fast memory, the performance difference between 2400 and 3200 is fairly large for ryzen, so a board using the "enthusiast" chipset that can't get memory going fast is kind of pointless to me.

Manufacturer Response:
Dear Jacob,

We sincerely apologize for any inconvenience this may have caused you.
For this case, we'd like to provide you some suggestions:
1. Install your memory on A2/B2 slot.
2. Load BIOS default and set XMP profile for trying.
3. Please increase a little DRAM voltage or loose timing for verify.
4. If possible, please change different CPU model because the memory controller is built into the CPU.


If you have any technical support inquiry, please contact us at http://www.ASRock.com/Support/tsd.asp
We will assist you shortly.

No USB support for Windows 7 12/10/2017 2:48:59 PM

Pros: Looks nice

Cons: No USB support for Windows 7. So, the USB ports don't work on Windows 7.

Dear William,

Thank you for purchase and review.
Due to Windows 7 does not build-in USB drivers for AM4 and Intel 100/200 series chipset, it needs to using Win 7 USB Patcher to create new Windows 7 installation media.
However, Windows 8.1/10 does not have this issue.

Please visit link below for Windows 7 with AM4 and Intel 100/200 series boards..
