Arrived DOA 8/29/2019 4:59:10 AM

Pros: Literally the only board that works for my CPU in an mATX case

Cons: Arrived DOA, all other components are fine but I have a brick for a PC at the moment

Overall Review: If you want an expensive doorstop that just blinks blue lights go ahead and buy this piece of trash.

Manufacturer Response:
Dear Kurtis,

We sincerely apologize for any inconvenience this may have caused you.
Please trouble shoot the mainboard whether the issue is resolved.
• Unplug the ATX power, remove all components from mainboard.
• Remove the mainboard from chassis, place it on mainboard’s box.
• Clear the CMOS.
• Reseat the CPU and heatsink fan.
• Test with single memory module (un-buffered).
• Reseat video card firmly and 6+6 PCIE power (if applied).
• Connect the monitor.
• Plug the 24 + 8 or 4 pins ATX power.
• Connect the chassis power switch to mainboard.
• Turn on the power to check if its post.

If you have any technical support inquiry, please contact us at http://event.asrock.com/tsd.asp

The Perfect (or only) x399m mATX board out there! 6/11/2019 11:26:43 AM

Pros: +Supports the Massive Wraith Ripper Heatsink (and does not cover first PCIE slot!)
+Overclocks the 2950x to 4Ghz stable across the board with ease! (1200 watt PSU)
+Supports a Monstrous Duo of RTX 2080 TI video cards! (not SLi, used for rendering)
+64GB of RAM support and 64PCIE lanes!
+Insanely Fast Triple M.2 Slot RAID Support!

Cons: More precautionary than cons:
-Will not install W10 without IOMMU disabled in North Bridge settings under BIOS even with latest 3.5 BIOS
-BIOS reports higher CPU temps due to zero software efficiency for scaling down CPU
-Manual states to use front audio jack for stereo-only speaker setup

Overall Review: Don't freak out like I did when seeing high CPU temps in BIOS, once you get into Windows everything is normal.

Also don't panic like I did if you can't get Windows 10 to install due to hanging at the logo screen. See above and disable IOMMU if you can't get it to install.

I seem to get weird static/noise when plugging a USB into the mainboard that's next to the audio output jack but I'm not sure if that's a grounding issue or if it's my speakers.

The illuminated gear is cool and Dr. Debug is very handy in diagnosing issues. I changed some settings and the board wouldn't boot, cleared CMOS and back in business again. Instant BIOS flash was a breeze and worked as expected. Do note that the board ships with the processor overclock switch enabled. I disabled it immediately at first due to the erroneous CPU temps in BIOS but back to normal now at a solid 4Ghz.

I would buy this board again, and again, and again.

Great besides the false CPU temps in bios 2/20/2019 3:52:59 PM

Pros: ALL PCI lanes are 16x and M.2's are all 4x. Great overclockable and has the same VRM's as the Asus Zenith Extreme. Running a 1950x overclocked on all cores at 3.8mhz (mild), and running 6 m.2 drives with the Asrock Ultra Quad M.2 Card( run in pcie#2) in raid 10.

Cons: The motherboard is giving off incorrect CPU temps in the bios. Have no idea how to fix it. Correct temps confirmed on "Coretemp" and Rysen Master.

Overall Review: I would recommend it for sure

The product is fine, but... 12/14/2018 6:45:17 AM

- Attractive price
- The only X399 MATX model on the market

Cons: - Board DIMM slot DDR4_A1 was DOA (only 3/4 slots work)
- Newegg refuse to repair / help
- Made several tickets to AsRock (no answer)

Overall Review: Iam still waiting for Asrock to reply, regarding newegg Iam disapointed.

Dear Haakon,

We sincerely apologize for any inconvenience this may have caused you.
Please trouble shoot the mainboard whether the issue is resolved.
• Unplug the ATX power.
• Clear the CMOS.
• Check the mainboard’s CPU contact pins are normal (should be pointing same way and pattern).
• Reseat the CPU and heatsink fan if socket pins are normal.
• Test with 1 x memory module on particular memory slot to verify.

Lots of bios options that need to be changed before an OS will install properly - such as IOMMU 11/20/2018 5:17:19 AM

Pros: Minor RGB lighting around cog. Several M.2 slots. Plenty of sata connections. Lots of USB

Lots of bios options for customizing

Handles ram that is not on its QVL list without issue. (gskill trident z)

Cons: PCI slots cant fit 270-280 mm long cards without blocking several pin connectors.

Could use another USB pin header for cases with multiple front USB's and card reader..

Overall Review: Will go with regular ATX size motherboard next time.

The one and only X399M board and yeah it's great! 10/24/2018 10:05:00 AM

Pros: -Only mATX X399M board out there
-SLI/NVLINK/Crossfire capable
-3 M.2 slots
-Came with latest BIOS to run 2950X out of the box
-Sale price
-RGB

Cons: -WIFI antenna are too close together
-M.2 #1 and #2 are only PCI, while #3 is SATA and PCI just FYI
-MSRP
-Always seems to be out of stock

Overall Review: If you are looking to go X399M in a mATX case then this is your only choice but boy is it a good one. 3 x PCI Express 3.0 x16 Slots with three card spacing means you can do SLI/NVLINK/Crossfire. It has a massive 3 M.2 slots but be reminded only slot #3 can do M.2 SSD SATA, others are PCI only. Latest BIOS out of the box allowed me to run my 2950X without any issue. My biggest qualm is the item seems to always be out of stock! Other than that an awesome mATX X399M board.

Good mobo, but... 10/23/2018 10:50:25 AM

Pros: It word "out of the box" however I was not able to install Win 10 initially due to common BIOS setting that needs to be changed (you can find this issue easily). Stable. Good for OC.

Cons: - BIOS need to be changed to install Windows 10
- my computer will not go to sleep, to be exact: I can put computer to sleep but it will wake up withing few minutes.

Dear Valued ASRock Customer,

Thank you for purchase and review.
IOMMU need to be disable in the BIOS (its common), if using Windows 10 is not RS2 (ver: 1703) or newer.
To avoid this, Please install Windows 10 RS2 (ver: 1703) or newer version.

For the wake up withing few minutes issue, please check the power option setting and the devices setting (i.e keyboard and mouse) and Wake Up Events with Event Viewer to verify which devices is waking up the system.
Or CMD (run as administrator) and in the Command Prompt type following: powercfg -lastwake

Works great for Threadripper 2, no problems yet 9/30/2018 7:27:02 PM

Pros: No issues installing CPU, NH-U9 heat sink, 4x4GB RAM, and graphics card.

BIOS upgraded via USB + flashback just fine (installed 1.10, then 3.20, then 3.30).

My NVMe drive in the top right M.2 slot is working great.

Cons: None yet.

Overall Review: My first ASRock purchase and first time installing a motherboard myself. I do software development and decided that a Threadripper 2 build would be a good replacement for my old quad-core.

I chose this micro ATX board based on personal taste and ASRock are the only ones that offer one for TR4. I don't need the extra slots of the ATX version.

The 24-pin power cord was a little hard to plug in, although I haven't installed enough motherboards to know if it was the motherboard's fault or the power supply's fault.

Haven't tried overclocking yet. My memory is advertised at 2666 MHz, it's currently running at 2133 MHz, but the XMP profiles in the UEFI appear to be available for 2666 MHz.

Last note: if you have an NVMe, make sure you install it first instead of last to avoid infuriating moments with the tiny little screw falling under the motherboard ;)
